2.3 Co nclusio
The chapter examined three theoretical views about the link
between economic growth and financial development: the one stating that the
financial sector development leads to economic growth, another putting economic
growth ahead of financial development and lastly the view which does not
support the importance of financial development on economic growth. On the
empirical side, a strong positive role of financial development on economic
growth has been found mostly in developed countries, and a weak or absence of
link in developing countries. In some cases, the demand leading hypothesis has
not been supported. In the next chapter we present the Rwandan financial
sector.

Financial Development and Economic Growth in Rwanda
CHAPTER 3
OVERVIEW OF THE RWANDAN FINANCIAL SECTOR 3.0
Introduction
This chapter narrows the financial development issue to
Rwandan case and highlights the weaknesses as well as the strength of the
Rwandan financial system. To situate the level of financial development in
macroeconomic perspective, a brief review of Rwandan economy is first
presented. The chapter finishes with a comparison of the financial sector in
Rwanda with those of other country members of East African region where Rwanda
and Burundi were admitted in 2008.
3.1. Overview over the Rwandan economy
Rwanda is a small landlocked country in Central-East Africa,
with 26,338 square kilometers. Its GDP per capita was $ 62.95 in 1970 with a
population of 3.7 million, eight years after its independence from Belgium in
1962. The country is hampered by mountainous terrain and distance from the
sea.
Rwanda is among most densely populated countries in Africa.
In 2009, Rwanda was ranked 29th among densely countries in 239
countries with density of 379 people per square kilometer, far ahead of the
African average of 34 people per square kilometer. In 2009, the population was
9.998 million, growing at 2.8 %, compared to African average of 1.66 %, thus
putting increasing pressure on agriculture land and environment (United Nations
Population Division, 2008).
Rwanda's economy is essentially rural; nearly 81% of the
population lives in rural areas (United Nations Statistic Division, 2009) and
derives its livelihood from subsistence agriculture, cultivating coffee and tea
for export with rudiment methods. Besides agriculture, there is exploitation of
scarce natural resources in some regions like cassiterite, wolframite, and
methane recently discovered in Lake Kivu.
Rwandan economy has been improving since 2000 with an
increasing growth rate especially for the last four years, when the country
maintained an average

growth rate vis-à- vis many African countries over the
period 2005-2008. In fact, the growth rate was 7.2 % in 2005, 7.3% in 2006, 7.9
% and 11.2 % in 2007 and 2008 respectively accumulating into an average growth
rate of 8.4 % above the African average rate of 5.82% during this period. In
addition, the country became the third, after Angola and Ethiopia (IMF, 2009).
Moreover, Rwanda has made considerable efforts in improving living conditions
of her population. Poverty has fallen by 3%, from 60% of the population living
under the poverty line in 2000/2001 to 56.9% in 2006 but leaving 37.9% still
extremely poor (IFAD website). However, Rwanda's development indicators are
still below the African and East African averages, as indicated by the table
below:

As the table indicates, for the period 1981-1990 Rwanda
reached the highest average per capita GDP with $323.5 compared to the average
of $276.6 during the recent period ranging from 2000-2008. In addition, it is
only in this period where its per capita GDP and the share of Gross capital
formation in GDP was

above East African average. This was mainly due to political
stability and favorable weather that prevailed during that time which made
agricultural sector to contribute a lot in GDP.
The period 1990-2000 was marked by war of four years
(1990-1994), the genocide of 1994 in which more than one million lost their
lives and insecurity which affected the north (1996-1998). This explains the
decrease in above indicators. Despite this situation, the growth rate of GDP
exceeded African and East African average, as the country was trying to
recover. Although the recent period was marked by the highest per capita GDP in
2008 with $ 458.49, but the period was characterized by a low per capita GDP in
the period ranging from 2001-2003, a figure less than $200.
It is worth to say that it is in 2008 where the country
recovered and passed over the level of per capita GDP reached before the
genocide, that of 1988 with $360.87. The per capita GDP has been declining as
from 1989, one year before the beginning of the war of 1990, up to 1994 from
$360.87 in 1988 to $207.43 in 1994. Since 1995, the economic growth started to
recover and currently, though the per capita GDP is still low, but Rwanda is
among top performing in Africa with the growth rate currently above both
African and East African average.
Many reasons explain the poverty of the country: being a
landlocked country, on this it added the bad governance which has characterized
the country since its independence, war, genocide and insecurity, lack of
natural resources, little skilled human capital, as per year 2005, less than 1%
of the population had a tertiary education, and a low level of investment.
3.2 The Rwandan financial sector
We analyse the financial sector by looking at the banking
sector, MFIs, insurance companies and financial markets. We begin by mentioning
that the Rwandan financial sector can be traced back from the creation of the
Central Bank, National Bank of Rwanda and issue of the local currency, Rwandan
Franc (RWF) in April 1964.

Financial Development and Economic Growth in Rwanda
3.2.1 Banking sector
The development of the financial sector before the genocide
of 1994 was slow. At the time, only 3 commercial banks and 2 specialized banks
operated with a total of less than 20 branches in the country, and one
microfinance (UBPR) with around 146 branches. The war and the genocide affected
heavily the banking sector: The genocide itself resulted in closure of the
Central bank for 4 months. The former government left the country in 1994 for
the DRC, after committing the genocide, with two-thirds of the national
monetary base in addition to US $7 million in cash which was taken from the
UBPR (Alson et al, 2001). Consequently, it took two years for this bank to
reopen, in 1996. Moreover, almost both physical and human capital of all banks
were destroyed during the genocide.
The post genocide period was marked by increase in number of
banks, where in 2002 there were 6 commercial banks with 28 branches, 2
specialized banks and 1 union of financial institutions (UBPR) with 148
branches (NBR, 2004). In 2007, commercial banks operated only 38 branches,
making only 7 % of all branches of financial institutions and by the end of
2008, 8 commercial banks, 2 specialized banks and 1 Microfinance bank were
operating.
However, there was a lack of competition as three banks (BCR,
BK and ECOBANK) held 66% market share before the licensing of UBPR as
commercial bank in 2008. This situation has led to high interest rate spreads
(8.6% in 2005), a modest 16% per annum growth in deposits over the past 5
years, and lending primarily to a core group of about 50 relatively large
customers concentrated in Kigali and a few sectors (Murgatroyd et al, 2007).
The penetration of banking sector is very low, and worse in
rural areas. The survey conducted by FinMark Trust in 2008 showed that in
general, only 14 percent of the active population use banks, 7% use MFIs, 26%
are informally served and 52% are financially excluded. In rural areas, less
than 6 percent of the population hold savings account in a formal finance
institution. Indeed, penetration of domestic credit to the private sector is
underperforming, with 11

Financial Development and Economic Growth in Rwanda
percent of GDP, compared to 18 percent of GDP for peer countries
(NBR, 2008).
Several reasons explain the underdevelopment of financial
services. The weak culture of savings among the people is due to low level of
per capita income in the country. In fact, in 2009 Rwanda was ranked
21st poorest of the least developed countries in the world and 56.9
percent of its population lives on less than US$0.45 equivalent a day, the
poverty threshold in Rwanda (IMF, 2009).
Secondly, a high spread between the deposit rate (around 7%)
and a lending rate (around 16%) does not provide an incentive to the public to
save. Many bank accounts are used as a payment mechanism for employees. It is
important to note that due to relative higher penetration of UBPR, it has been
upgraded to commercial bank in 2008 and became BPR S.A, and that KCB, a new
regional bank from Kenya has been licensed.
3.2.2 Microfi na nce institutions
Microfinance initiatives mushroomed from 2002, primarily as a
response to the weak involvement of the traditional banks in small and micro
enterprises, and rural areas. Sixty-three microfinance institutions were
licensed in 2006 (Habyalimana, 2007).
In 2009, the microfinance sub-sector consisted of around 125
MFIs including 111 COOPECS (Kantengwa, 2009). In June 2006, NBR estimated that
MFIs represented 24.18% of the total financing of the economy with RWF 59bn
(equivalent of $100 million) out of RWF 244bn of credit of the financial
institutions and 25% of savings mobilization. The mobilized savings amounted to
RWF 65bn (equivalent to around $.110 million) out of RWF 259bn. Informal
finance is so popular that 73 % of total population reported using informal
loans in 2005 (Habyalimana, 2007).
However, Microfinance institutions are inexperienced,
characterised by management with poor corporate governance, weak information
systems, important losses caused by poor internal organisation and a
mismanagement of their loan portfolio (Kantengwa, 2009). All these weaknesses
culminated into

the failure of nine microfinance institutions in 2006 with
total deposits of more than $5.3 million, leading to a general panic (NBR,
2007). To include rural population in the financial system, UMURENGE SACCOs was
introduced in the end of 2008, a saving scheme to be operating in each of 421
sectors.
3.2.3 Insurance and pension funds
This sector comprises 5 classic insurance companies (SONARWA,
SORAS, COGEAR, CORAR and Phoenix of Rwanda Assurance Company) and six insurance
brokers. In 2006, only about 3% of the active population held insurance policy.
In addition, there are three public medical insurance companies: RAMA, MMI and
Mutuelle de Santé and one private company, AAR Health Services, licensed
in 2008. The relatively well performing RAMA and MMI serve only 5% of the
population (NISR, 2008).
The pension sector is assured by one Public Pension fund
(SSFR) and 10 Growing Private Pension funds. The SSFR covers only 7.5% of
active population and on overall less than 8% of the active population is under
pension schemes (NBR, 2009).
3.2.4 Financial markets
In January 2008, Rwanda established a capital market with the
creation of an Over-The-Counter market operated and regulated by a Capital
Market Advisory Council (CMAC). However, its market capitalisation is still
very low as only $ 360, 000 has been traded in 15 transactions (the average of
$24,000 in each transaction) and newspapers frequently reported that the OTC
has been silent due to lack of transactions recorded. The main reason is the
poverty of Rwandan citizen which does not allow the culture of saving where
even those who earn monthly salary are able to spend it for survival only. With
regard to market participants, Rwandan OTC has 7 members divided into three
categories: Stockbrokers, Dealers and Sponsors (CMAC website).
3.2.5 Financial liberalization i n Rwanda
Before the financial liberalization, tools of monetary policy
were mainly credit rationing, directed credit and interest rate controls.
The financial deregulation

was characterized by legal reforms affecting the nature of
central bank supervision and new tools of monetary policy were introduced like
regal reserve requirements and discount rate, alongside the abolition of
interest rate ceilings, directed credit and credit rationing as well.
The process of financial liberalization started in March 1995
by the liberalization of exchange rate and interest rate in 1996. In the same
year, banking structure was opened to foreign investment and entry requirements
for MFIs were relaxed. However, despite abolition of controls on interest
rates, the rigidity in the later is still observed, fluctuating around 16% for
lending and 7% for deposit rates of interest, due to oligopolistic nature of
the banking system.
The period 2004-2006 was characterized by take over of
nonperforming banks due to poor corporate governance. BACAR and BCDI were taken
over by FINABANK and ECOBANK respectively, and the government sold its majority
of share in BCR. In 2006, the spread of MFIs nationwide came as another step in
financial liberalization, following the failure of commercial banks to deliver
in rural areas. However, as prophesized by Diaz-Alejandro (1985), the end of
2006 and 2007 turned the financial sector in crisis as consequence of
unmonitored regularization, after which the central bank started exerting basic
controls on financial institutions through micro finance law and regulation
adopted in 2008, and strengthened by creation of MFI association created in
2007.
3.2.6 Monetary policy i n Rwanda
Monetary policy is a responsibility of the NBR and is a part
of the annual economic program aiming at implementing the medium-term program
referred to as EDPRS. Like all central banks, NBR uses open market operations,
reserve requirements (fixed at 8% before 2009 and reduced to 5% from 2009), and
discount rate (which fluctuates between 7.5 % and 8%). With its basic objective
of price and foreign exchange stability, its development can be regarded in two
periods: the period of financial regulation, from 1964 to 1995 and after
liberalization in 1995.

Before 1995, the country was in fixed exchange rate regime.
From 1970 to 1990, the foreign exchange rate was 1$ for nearly 82 RWF. However,
the war period 1990-1994 saw many devaluations, especially that of 1991 with
51.5 % and that of 1994 of 91.64% and by the end of 1994, the exchange rate
stood at 1$ for 220 RWF (DUSHIMUMUKIZA, 2006).
The period of flexible exchange rate was characterized by
volatility in exchange rate. As evidence, in January 2003, the average exchange
rate stood at 511.2168 RWF for 1$, but by end of the year, the exchange rate
was at 574.83RWF for 1$. The depreciation rate stood at 11.6% from one year to
another. If we compare the average exchange rate of 2002 and 2008, the index is
115.2 in six years, from the exchange rate of 475.32 FRW for 1$ in 2002 to
547.61 FRW for 1$ in 2008 (NBR, annual report, 2008). Indeed, this exchange
rate can be compared to 220 RWF for 1$ in 1994.
Regarding price stability, again the rampant inflation
characterized the after liberalization period, as compared to the period before
where the price stability was observed. Evidence from Kigali (the Capital city)
in 2003 shows that the CPI for all products in constant terms of 1982 was
559.32 compared to the CPI of 408.93 and in 1996 (NBR, annual report of 2003).
The inflation rate is fluctuating around 7.5%
For money supply, there was an upward trend in money supply
to the level where its growth rate was above that of GDP. For instance, in
2007, increase in money supply was 31.25% against 13% of nominal GDP. Indeed,
in some years, the money supply experiences an over expansion, especially
during election periods like 2003 and 2008.
For payment system monetization, SIMTEL was introduced in
2005 aiming at speeding up the level of financial innovation, which is very
low, as in 2008 the value of transactions using bank cards was 0.59 percent of
the non cash payment instruments (dominated by cheques) and cash payment
represented 98% of the payment system (NBR, 2009). Introduction of Real Time
Gross Settlement and an Automated Clearing House were few among mechanisms of
such modernization.
Financial Development and Economic Growth in Rwanda
3.3 Comparison of financial development within
EAC
The discussion omits comparison based on the number of
financial institutions as the countries are not equally sized and formal
financial markets since Rwanda and Burundi do not have them while Kenya
launched its stock market (Nairobi Stock Exchange) in 1954 and those of
Tanzania and Uganda are operational since 1998. We rather use some ratios
regarded as proxies of the level of financial development.
The need for this comparison lies in the sense that the
macroeconomic policies of these countries are tied together, hence it pays for
Rwanda to know its status quo in this community of countries. Three indicators
are used: Liquid liabilities as % of GDP, claims on private sector to GDP ratio
and domestic credit to GDP ratio. Data which are sources of the figures are
presented in appendices.
3.3.1 Ratio of Liquid liabilities (M3) to
GDP
Rwanda and Uganda are the last and their M3/GDP ratio are far
below the average of the AEC (21.98 % of GDP) with Kenya leading at 39.77%
compared to 15.35% of Rwanda, as shown by the chart below:

On overall, Kenya comes first followed by Tanzania, Burundi,
Rwanda and Uganda. We noted that in 2005, worldwide ranking of these countries
were: Kenya 94th, Tanzania 113rd, Burundi
118th, Rwanda 131st and Uganda 132nd out of
173 countries, with weighted average of 58%.

Financial Development and Economic Growth in Rwanda
3.3.2 Claims o n private sector to GDP ratio
This indictor was suggested by some researchers as the best
measurement of the level of financial depth as discussed in chapter two. The
figure below indicates the level of financial depth in East African Countries
had been this indicator used.

Figure 2: Evolution i n average of claims o n private

Kenya is still leading followed by Burundi whereas other
countries are almost at the same level, which is very low below the average of
14.75%. Rwanda is the fourth with 7.05% while Uganda is the last in the group
with 6.11%. Based on this indicator, we can say that Kenya enjoys a financial
deepening four times that of Rwanda. However, Rwanda has been improving but at
a slow rate compared to Burundi which made a significant improvement. This
ratio for Burundi was more than three times that of Uganda and more than double
that of Rwanda in recent period, while 30 years ago the difference between
these countries was slightly small (less than 3%).
3.3.3 Domestic credit to GDP ratio
As the next figure shows, Burundi has been improving
considerably from the last in row during the period 1970-1975 (with 9.45 %) to
the 2nd position (with 36.62%) for last two consecutive periods,
from 1995 to 2005. Surprisingly, this indicator declined considerably in
Rwanda's post genocide where it moved from 17.51% as the average for the war
period of 1990-1995 to 11.54% for the last period 2001-2005 while the country
was supposed to be putting enough effort in the credit to private sector to
speed up the economic growth.

This ratio for Rwanda was below the EAC average throughout
the period. Moreover, there is an increasing gap between Rwanda, the last in
group, and Kenya, the first, from 11.46% over the period 1970-1975 to 27.97%.
This is one among reasons that explain the gap in the level of economic
development among these countries. Uganda and Tanzania too have the low ratio.
Though several reasons can explain why Rwanda is lagging behind in financial
development, civil war, insecurity and poor governance are paramount factors to
the explanation. However, a detailed analysis is needed to explain why Tanzania
and Uganda are not performing well in some areas while they enjoyed a relative
stability, contrary to Burundi which was in war since 1993 up to 2005 and
performed well.
3.4 Co nclusio
Rwandan economy has been growing during post genocide period
but still the economy is at the lower level when compared to other countries.
Indeed, the financial development is still low and below the average of the
East African countries. When considering some indicators of the financial
development over the period 1970-2005, Rwanda is almost the last within five
countries though Uganda and Tanzania too are not performing well. This
observation brings to mind the empirical question of the extent to which the
level of financial development in Rwanda is linked with the level of economic
growth. Therefore the following chapter presents the methodology followed to
conduct this study.
Financial Development and Economic Growth in Rwanda
CHAPTER 4
METHODOLOGY
4.0 I ntroductio
This chapter presents the methods and techniques, the model,
estimation techniques and types of data used in this study in investigating the
causality among the proxies of financial development and economic growth.
4.1 Meaning and rationale of the model used
The use of VAR was motivated by its ability to capture the
dynamic interaction of financial sector development and economic growth. A VAR
is a direct generalization of the univariate AR(p) model to the case of a
vector of variables and is used to express the dynamic correlations between the
variables and hence is considered as an alternative to large-scale simultaneous
equations structural models (Brooks, 2008).
It allows treating each variable as endogenous thus avoiding
restrictions, judged incredible by Sims (1980), imposed by univariate AR, by
specifying some variables as being exogenous. This model was chosen because the
changes in indicators of financial development are possibly correlated with the
disturbance term in the equation of economic growth. This is because an
unobserved factor that influences growth of GDP may very well influence
indicators of financial development, making them endogenous. Further more, this
study joins other studies on the matter which used the VAR frame work, namely:
Hassan and Jung-Suk (2007); Teame (2002); Sakutukwa (2008) and others.
4.2 Model specification and rationale of
variables
In a VAR model, all variables have equations linking the
change in that variable to its own current and past values and the current and
past values of all the variables in the model, as it describes the dynamic
evolution of a number of variables from their common history (Verbeek, 2004).
The model is expressed
in a matrix form as:Yt = B +
Elic_i AtYt_i + Et with:
V, = ( GRATES
DEPTHBANKPRIVATESOPHT )

Yt : It is a 5×1 column vector of 5 variables
including proxy measures of the financial development, B is a 5×1 column
vector of constants, At and
Yt_i are
5×5 matrices of coefficients and lagged variables
respectively, i is the lag length
to be determined by AIC criteria and et is a 5×1
column vector of error terms. Variables included in the models are:
GRATE = Growth rate of Real per capita GDP, following the works
of Sinha and Macri (2001) and Kesseven et al (2007);
DEPTH = Claims on Private sector to GDP ratio considered as
proxy of financial deepening, following the works of Karima and Holden (2001),
Firdu and Struthers (2003) and Zhang et al (2007);
BANK = Domestic credit by deposit money bank and other banking
institutions divided by total domestic credit;
PRIVATE = Claims on the non-financial private sector to gross
domestic credit; SOPHT = Ratio of broad money to narrow money (M2/M1) as proxy
of financial sophistication, following the work of Sakutukwa (2008).
BANK and PRIVATE are inspired by the work of Levine and King
(1993). Unlike to them, we have included the domestic credit for other banking
institutions in BANK to mitigate the drawbacks of this indicator as commercial
banks are not the only financial institutions to provide valuable financial
functions. However, there is still a weakness in these proxies in Rwanda
because data used on assets of financial institutions do not include the UBPR
which play an important role in Rwandan financial sector.
4.3. Model estimatio
4.3.1 Statio narity and coi ntegratio
Due to spurious regression resulting from nonstationary
series in the regressions, we have conducted the tests for stationarity, using
ADF to check whether the residual series are white noise. The tests for
cointegration have been conducted to determine the form of the VAR to be
estimated. In fact, trend stationary variables are estimated by OLS, if the
variables contain stochastic trends and cointegrated, a VECM is used and
finally if the variables are not stationary and not cointegrated, the model is
estimated after the stochastic

trends have been removed by taking first differences of the data.
All tests were run within Eviews 6.
4.3.2 Granger causality tests
To determine which sets of variables have a significant
effects on each dependent variable, causality tests have been conducted by
restricting the coefficient of the lags of a particular variable to zero
(Wooldridge, 1990). The objective is to find out if changes in one variable do
affect changes in another variable and vice versa. If this is the case, as
explained by Brooks (2008), a sets of lags of the included variable should be
significant and it would be said that there is a bi-directional causality,
otherwise it should be said that some included variables are exogenous or no
causality exists at all between variables had been all lags insignificant.
4.3.3. Variance decomposition and Impulse
response
The ambiguity in interpreting individual coefficients in VAR
model (Gujarati, 2004) motivated us to use the variance decomposition and
impulse response function which trace out the response of the dependent
variable in the VAR model to shocks in the error term for several periods in
the future, keeping constant all other variables dated t and
before.
4.4. The data source and measurement
The five considered time series are ratios we have computed
from data provided by the IFS Yearbooks. The database includes 42 annual
observations from 1964 to 2005. Unlikely to previous studies which used natural
logarithm of the series, we did not find any graphical relationship, as advised
by Gujarati (2004), which motivates a priori transformation of the data to
log-log model.
4.5 Co nclusio
This chapter has presented the methodology that has been used
in this study. The next chapter presents and analyses the results of
econometric estimation. The main objective of the chapter is the hypothesis
testing.

Financial Development and Economic Growth in Rwanda
CHAPTER 5
MODEL ESTIMATION AND FINDINGS
5.0 I ntroductio
So far we have presented the literature both on theoretical
and empirical side on the causality between economic growth and financial
development. It is now time to turn to the empirical testing of this
relationship for Rwandan economy. This chapter presents the results obtained
from econometric testing and discusses the meaning and reason behind the
figures.
5.1 Test for statio narity
The footstep of this analysis is to determine whether the
series are stationary or not. The ADF was used to test for stationarity of
these series as it provides a superior test to DF, especially in case the
residuals of the regression could be serially correlated. The lag length has
been automatically selected by AIC from nine proposed lags and all three
possibilities have been tested: neither intercept nor trend, intercept but no
trend and both intercept and trend. In all cases, results were found similar
irrespective of the model used.
Here we present the results from the general model including
intercept with
trend, as depicted by: AYt=f3i +
f32t + SYt_i + al El:=i AYt_p + Et.
In addition, we have tested for the presence of trend in series,
with the model:
Yt =cx +f3t + Et. The presence or the absence of the trend will
be used for
subsequent tests. The table below presents the results:

The hypotheses tested are:

there is no trend

After taking first differences of SOPHT and BANK, the series
were found to be stationary at 1%, as the table below depicts:

The above results conclude that GRATE, DEPTH and PRIVATE are
I(0) while SOPHT and BANK are I(1). Therefore, VAR in levels cannot be
applied.
5.2 Test for coi ntegratio
In econometric literature, it is not clear whether
cointegration should be applied to only series integrated of the same order.
Though Verbeck (2004) noted that the concept of cointegration can be applied to
(nonstationary) integrated time series only and Dickey et al, quoted by
Gujarati (2004), stipulated that Cointegration deals with the relationship
among a group of variables, where (unconditionally) each has a unit root,
however Brooks (2004) stressed that it is also possible to combine levels and
first differenced terms in a VECM. The later therefore illustrates that
cointegration can exist among variables not integrated of the same order.

Heij et al (2004) developed the mathematical proof of this
view where they asserted that a cointegration relationship exists between
stationary and nonstationary variables. If their mathematical proof is put in
simple terms, there are three possibilities in VAR with many variables: If m:
the number of variables, r= rank of the matrix of coefficients and also the
number of cointegration relations, therefore:
· If all variables are stationary, r=m and all roots lie
outside the unit cycle
· If all variables are not stationary, r=0, there are m
unit roots or m stochastic trends.
· If some variables are stationary and others not
stationary, r= 0<r<m, there are m-r unit roots, the polynomial have m-r
common stochastic trends and there are r cointegrating relations.
As some variables are stationary and others not, Johansen
cointegration test has been used to determine whether there exists a long-run
relationship between these variables. This test was preferred to Engle-Granger
approach because in case of five variables we may have more than one
cointegrating relationship (Brooks, 2004).
a) Johansen coi ntegratio n test
Johansen trace test was used on the number of cointegrating
relations with null hypothesis of no cointegration between series against the
alternative hypothesis of existence of cointegration between the series. All
variables enter the cointegration analysis in levels. This table depicts
cointegrating vectors for each model with 4 lags.

*Critical values based on MacKinnon-Haug-Michelis (1999)
All five possibilities about the nature of deterministic trend
assumption suggest that the series are cointegrated. At least there is one
cointegrating factor except the Max-Eig method with neither intercept nor
trend in data, which is unlikely to

be the case. The subsequent step is to determine whether an
intercept or trend or both are included in the cointegrating relationship and
to present the results of the selected model. The analysis of the nature of
trend conducted showed that all variables except GRATE have significant
intercept and trend. After estimating the selected model of both intercept and
trend with 3 lags selected by AIC, the results were as follows:

Trace test indicates 1 cointegrating eqn(s) at the 0.05 level *
denotes rejection of the hypothesis at the 0.05 level **MacKinnon-Haug-Michelis
(1999) p-values
The statistic of 137.1 considerably exceeds the critical value
(of 88.8) and so the null of no cointegrating vectors is rejected. But the
2nd row shows that the null hypothesis of at most one cointegrating
vector can not be rejected as trace statistic of 55.19 is less than critical
value of 63.9. Therefore, there exists one cointegrating relation which means
that the rank of the matrix (r) is one.
The results from trace test were the same if maximum
eigenvalue test was considered. As there is one cointegrating vector, this
allows us to estimate a VECM, in line with advice of Brooks (2004) of not using
models in differences when cointegration is present, as this flows away
important information and have no long-run solution.
5.3 Vector Error Correction Model (VECM)
The lag length was chosen based on AIC, which was consistent
with LR and HQ. Noting that as data are annual observations, a maximum of 4
lags is reasonable, as suggested by Brooks (2004) based on the frequency of the
observation and AIC picked 3 lags. The estimated output is presented in the
appendix, but the table below presents the significant lags at 5% level.

The Error correction term showing the long-run equilibrium is
estimated as:
CointEgl = GRATEt_i -- 0.057 SOPHTt_i + 0.0019 /31t -- 0.0019
/30
+ 0.332DEPHTt_1 -- 0.114 PRIVATEt_i + 0.298BANKt_1
In all equations, the cointegrating equation has a negative
sign as expected and significant in three out of five equations. We note from
the table above that in many equations of the VECM, the coefficients of lags of
other variables are not significant, especially for PRIVATE which is determined
solely by its own lags, SOPHT is explained by one lag from PRIVATE whereas for
DEPTH only its own lags and 1 lag of SOPHT are significant.
The cointegration is strongly significant for GRATE, DEPTH and
SOPHT. However, as noted by Brooks (2004), evaluation of the significance of
variables in a VECM is based on the joint tests on all of the lags of a
variable in the equation rather than individual coefficient estimates.
Therefore we proceed to F test as indicated in the table below:

Critical values of F-statistic are taken from F-statistic table
provided by Gujarati (2004) and are 3.09; 2.2 and 1.84 for 1%; 5% and 10%
respectively. The VECM

shows that for GRATE the null hypothesis being all
coefficients are simultaneously zero is rejected at 1%, for DEPTH and SOPHT the
null hypothesis is rejected at 5%, for BANK it is rejected at 10% and for
PRIVATE the null hypothesis can not be definitely rejected.
The results suggest that there exist: a long-run relationship
between growth rate of real per capita GDP and proxies of financial
development, a long-run relationship between financial depth, rate of growth of
real per capita GDP and other included measures of financial development and
the same applies to financial sophistication. The F-test denies any long-run
relationship between the ratio of credit to private sector to total domestic
credit with GDP, and other measures of financial development and for the ratio
of credit allocated by banks to total domestic credit when 5% level is
considered.
5.4 The E ngle=Gra nger test
The test is meant to detect any short-term relationship
between the variables and it is applied to test whether the changes in one
variable can cause changes in another variable and vice-versa. As there is a
long-run relationship between variables, the error correction term will be
included in the Granger causality test for estimating a short-run relationship.
It is worth noting that Granger causality test should be applied to stationary
series (Sinha and Macri, 2001). Therefore, we have applied this test with
differences in non-stationary series. When estimated the VAR model with
differences in nonstationary variables to come up with lag length, the AIC and
HQ criteria gave out 5 lags. The model to be estimated is:
M'at =0(0-Foci ~ 78 ~ ~~ ~ 98 ~
8 8 ~~ where Ya and Yb are
~~~ ~~~
variables on which causality test is being applied. The
hypotheses to be tested are:
Ho: âi=0, Yb does not Granger causes Ya
H1: âi ?0, Yb does Granger causes Ya
The results for Granger causality are presented in table
below:

The table above gives the probability values at 5% for the
null hypothesis that all the lags of a given variable are jointly insignificant
in a given equation. The second row after the headings shows that all the lags
of DEPTH and DSOPHT are jointly significant in explaining the changes of GRATE
(values less than 0.05). Indeed, both lags of GRATE and DEPTH jointly explain
the changes in DSOPHT. Moreover, a part from the lags of PRIVATE which jointly
explain DBANK, there is as well no causality between DEPTH and other variables
as applied for PRIVATE.
The Engle-Granger causality suggests that in short-term, there
is unidirectional causality from financial deepening to growth rate of real per
capita GDP and bidirectional feedback between financial sophistication and
growth rate of real per capita GDP. But other proxies of financial development
do not seem to have affected economic growth, or being affected by economic
growth.
5.5 Impulse responses and variance
decompositions
The Granger Causality solves the problem of existence or not
of variables with significant lags in the model but will not indicate whether
there is a positive or a negative relationship between variables or how long
the effects will take place. Fortunately, this information is given by Variance
decomposition and Impulse responses.
5.5.1 Variance decompositio
Gebhard and Wolters (2007) define variance decompositions as a
determinant of how much the s-step-ahead forecast error variance of a given
variable is

explained by innovations to each explanatory variable for s = 1,
2, etc. The estimated variance decompositions are as follows:

The data shows that in period 1, changes in Growth rate of GDP
are due to its own shocks at 100%. However as time passes, the effects of
shocks of other proxies of financial development to GDP increase significantly,
especially financial depth shocks, which increase from 0 in period 1 to 56% in
fifth period and represent more than 45% of all shocks on GDP from period 5-7
and nearly 40% above period 8. For Financial sophistication, although its
shocks to GDP are low up to fifth period, they become important in the
long-run, as they account from 10% - 20% of the whole shocks in GDP growth
rate.
In long-run, BANK and PRIVATE exert some influence on Growth
rate of GDP as they account for around 9% and 6 % respectively after the
seventh period. This leads to a considerable decrease of responsiveness of
growth rate of GDP to its own shocks from the range of 20% to 30 % after the
fifth period.

From the first period, the shocks in GDP growth rate account
for 6.59% of the shocks in DEPTH and no other variable exerts a shock on
financial depth. However, as from the fourth period, the financial
sophistication exerts a relatively higher significant influence on DEPTH than
other variables, around 20%. Shocks in rate of GDP account still for around 5%
and 2.8% for PRIVATE. It is noted that the impact of BANK shocks as well
increase in the long-run, from 0% to 10.25% from the first period onwards.

From the above table, the shocks in growth rate of GDP account
for 26.69% in explaining changes in financial sophistication whereas its own
shocks account for 73%, as other variables do not influence SOPHT in the first
period. However, this order changes over time as financial depth takes over
growth rate of GDP in explaining changes in financial sophistication. In fact,
starting from the third period, shocks in financial depth lead to variability
in financial sophistication by 11.7% compared to 9.6% of growth rate in GDP
where still its own shocks account for more than 60%.
The influence of financial depth increases considerably up to
40% in sixth period and the own shocks decline to 31.95%, coupled with an
increase in influence of BANK with 20.92% and a decrease in influence of GDP
rate from 26.69% to 3.23% and remained at this level. The impact of PRIVATE
shocks

remains low close to 3.5% whereas that of shocks from
financial depth account for 40% to 45% in long-run, leaving the own shocks
between 30% to 23% and BANK shocks around 23%.

The part of changes to BANK due to its own shocks declines
sharply from 89% in the first period to around 40% in long-run. In the
short-run, shocks from DEPTH have a largest impact on BANK, varying from 7% to
21% whereas in long-run, shocks from SOPHT outweigh DEPTH shocks in explaining
changes in BANK. Financial deepening and sophistication continue to exert a
significant influence on the ratio of sources of credit (BANK), contributing to
40% of BANK shocks in the long-run (from the fifth period). Whereas, the shocks
from growth rate of GDP and PRIVATE account for nearly 6% and 10%
respectively.

Compared to other variables mentioned above, PRIVATE own shocks
are relatively small (55.5%) in the first period, and the shocks decline
sharply to a

quarter in long-run. Shocks from Financial sophistication have
a strong influence on PRIVATE and account for more than a half of total shocks
from the fourth period onwards. Shocks from BANK are insignificants as they do
not account for 2% and shocks from growth rate of GDP and DEPTH together
account for nearly 10% of total PRIVATE shocks.
5.5.2 Impulse response models
Gebhard and Wolters (2007) define impulse responses as the
measure of the effect of a unit shock of the variable i at time t on the
variable j in later periods. So for each variable from each equation
separately, a unit shock is applied to the error term and the effects upon the
VAR system over time are noted. Details of impulse responses are presented in
appendices and their summarized results are:
o Positive shocks of DEPTH and BANK to GDP growth rate but
negative shocks from SOPHT and PRIVATE.
o Positive shocks on DEPTH from GDP growth rate, financial
sophistication and BANK in short-run. Moreover, SOPHT and BANK have positive
shocks on DEPTH in long-run and negative PRIVATE shocks on DEPTH.
o Positive shocks on financial sophistication from BANK and
growth rate of GDP in short-run and negative shocks from growth rate of GDP,
DEPTH and PRIVATE in long-run.
o Positive shocks on BANK from PRIVATE and negative shocks from
growth rate of GDP and financial sophistication.
o Negative shocks on PRIVATE from all variables.
In the results above, the ordering was GRATE, DEPTH, SOPHT,
BANK, and PRIVATE. Unfortunately, the main drawback of Variance decomposition
and Impulse responses is that if the variable order is altered the results will
change too. For independent results from variable order, a priori knowledge
about the order is required, but not easy in most interdependent financial time
series data.
5.6 Discussion of findings
The tests revealed a long-run relationship between the Growth
rate of real per capita GDP and 4 proxies of financial development.
Precisely, financial

deepening and financial sophistication were revealed to be
associated to this rate of GDP in the long-run. This implies that as the
economy allocates more credit to the private sector, as new financial
instruments are introduced in Rwandan financial system, with time, then the
level of economic growth will be affected. The causality test, Variance
decomposition and impulse responses show that financial deepening influences
positively economic growth. But no bidirectional causality detected from growth
rate of GDP to financial deepening.
These results confirm the importance of the level of financial
depth for Rwandan economic growth, unlikely to the conclusion of some
researchers who used panel data analysis and affirmed the irrelevance of the
level of financial deepening on economic growth for Sub-Saharan Africa and poor
countries in general, as noted by Hassan and Jung-Suk (2007) and Michael and
Giovanni (2001). Our results do agree with the conclusions of Zhang et al
(2007) in China, Demetriades and Luintel (1996) in India and Sakutukwa (2008)
in Zimbabwe.
The causality test and variance decomposition showed a
bi-directional influence between the level of financial sophistication and
economic growth. Surprisingly, impulse responses show that this relationship is
negative and a mere interpretation may conclude that financial sophistication
aggravates economic growth. But there can be an intuitive explanation of this
situation: «the true measurement of the financial sophistication in
Rwanda». The used growth rate of real per capita GDP excludes effects of
inflation and the increase in the ratio of M2 to M1 used as proxy of financial
sophistication could imply increase in money supply due to inflationary
pressure rather than financial innovation.
This is the case for Rwanda where post genocide economy was
characterized by high rate of inflation and volatility in exchange rate.
Despite the increase in the quasi-money which resulted in the increase of the
ratio of M2 to M1, there was no E-banking in Rwanda up to 2005, no remarkable
new financial instruments and ATM cards were recent in few banks, in major
towns only.
No link was found between economic growth and allocation of
credit. Were the relationships to be established by Granger causality, the
impulse responses

show that the relationship would be negative. The absence or a
negative relationship between the growth rate of real per capita GDP and
PRIVATE, and between PRIVATE and DEPTH can be explained by the allocation of
credit. Credit devoted to agricultural sector which employs more than 80% of
the population was less than 1.5% of total credit to private sector while the
manufacturing, trade, restaurants and hotels received more than 60% of the
total credit, while these sectors employ less than 5% of the population and
contributed to only 17.4% in GDP in 2005.
Moreover, some loans were given to no profitable projects and
non credit worthy customers as indicated by the high level of defaulters which
led to bank crisis in former BACAR, BICDI and many MFIs. These findings of
negative relationship between credit allocation and economic growth conquer
with findings of Karima and Holden (2001), in a panel of 30 developing
countries.
5.7 Co nclusio
The study finds a strong positive causality from financial
deepening to economic growth and a negative bi-directional feedback between
economic growth and financial sophistication, in the short-run, and a long-run
relationship between economic growth and proxies of financial development.
The lack of short-run relationship between economic growth and
the credit allocation, from the source (commercial bank versus central bank) to
the users (private sector versus public sector) has been confirmed, while in
the long-run, variance decompositions and impulse responses showed a minor
relationship between economic growth rate and credit allocation. The found
negative link between level of economic growth and financial sophistication is
explained by the lack of accuracy of measurement of financial sophistication in
Rwanda. The next chapter will therefore put forward the general conclusions and
recommendations of the study.

Financial Development and Economic Growth in Rwanda
CHAPTER 6
CONCLUSIONS AND RECOMMENDATIONS
6.0 I ntroductio
This study intended to examine the bi-directional influence
between financial development and economic growth in Rwanda from 1964 to 2005.
Chapter one presented the existing problem which was the rationale of our study
alongside the objectives, research hypotheses among others. Chapter two
reviewed the literature on the subject both on theoretical and empirical
ground. In chapter three, a comparative analysis of the level of financial
development within East African countries has been carried out and revealed a
weak level of financial development in Rwanda. The results indicate that Rwanda
either takes the fourth or the last position among five countries.
In chapter four, we have explained the methodology followed,
focused on a VAR with five variables, namely: the indicator of financial
deepening, financial sophistication and other two indicators of the credit
allocation, and the growth rate of real per capita GDP was used as proxy of
economic growth. The fifth chapter has been devoted to econometric testing.
This chapter summarizes the results of the study and gives recommendations as
well as areas for further studies.
6.1 Summary of findings
The empirical results demonstrated both a short and a long-run
relationship between both financial depth and sophistication and economic
growth. For financial deepening, the causality runs from financial deepening to
economic growth and for financial sophistication, the causality is
bi-directional but negative. As some studies have concluded, we have not found
any evidence of the link between credit allocation and economic growth and even
if the relationship was to be significant, it would be negative. This is
explained by the pattern of the credit to private sector which has become
increasingly skewed to service sector with less employment and loan defaulters
rather than to agriculture and businesses for productive investments.


All in all, we found that the level of financial development
matters most for Rwandan economy, contrary to the irrelevance of the financial
development on economic growth in cross-sectional analysis for developing
countries confirmed by previous studies. The reason being that their analysis
does not take into consideration country's unique characteristics or the
results are biased by the presence of outliers in their regression, due to size
inequalities of countries within a region.
The first and fourth hypotheses were partly confirmed while
the second and third could not be confirmed. The study has attained its
objectives and recommendations for further strengthening both Rwandan financial
sector and Rwandan economy in general have been suggested.
6.2 Policy recommendations
Based on the results of the study, it is urgent that Rwandan
government takes the financial sector as a pillar of economic growth which can
replace non performing industrial sector and agriculture. The emphasis put on
it can allow Rwanda to be the net exporter of financial services within East
African Community and Commonwealth where Rwanda was admitted recently, as we do
not have any comparative advantage in remaining sectors.
The emphasis should be put on the level of financial
intermediation through increase in the credit allocated to private sector. It
is however important to note that the allocation of the credit should be
changed from private consumption and services to agriculture and other
investment projects like construction sector. Additionally, credit allocation
should be based on the profitability of the investment rather than personal
considerations or values.
More so, Rwandan government should accelerate financial
innovations which are currently very low, by making compulsory: distribution of
ATM cards by banks upon bank account opening; and the use of credit cards as a
means of payment in strong legalized supermarkets and shops, as a first step in
the introduction of card-based system of payment.
BPR S.A has provided evidence that bank branch proximity is a
key factor in bank profitability. It is therefore, recommended that other
commercial banks in Rwanda should open at least one branch in each district.
Due to the absence of positive impact of financial innovations on economic
growth explained by inflationary pressures and exchange rate depreciation, the
Government of Rwanda should put more efforts on price and exchange rate
stability.
The introduction of OTC market was a good step for financial
development. However, a lot need to be done regarding empowering the saving
capacity of Rwandans, by policy measures enhancing an equal distribution of
income, poverty eradication and the fight against rampant unemployment. We
believe these factors to have been the reasons for the absence of transactions
on OTC market rather than lack of public awareness as reported by
newspapers.
For employed population, the government of Rwanda should
ensure that the salary is enough to cover the subsistence needs so that saving
is possible. This can be done through the minimum wage legislation since a
larger group of employed people earn even what is not enough for family
expenses. In such conditions, any policy aimed at saving mobilization would
futile.
We can not claim that the study has explored all areas of the
problem. For instance, we have not used the level of stock market development
in our econometric analysis due to lack of data as the existing OTC started in
2008.
6.3 Areas for further research
Studies need to be conducted to determine best proxies of
financial development in Rwanda, especially for financial innovations, as the
used ratio of M2 to M1 may reflect the increase in classical saving functions
rather than diversification of financial instruments and use of modern
technology in the financial sector. Indeed, a cross-sectional study in EAC
would be interesting, to assess how developed financial systems are and how
they are relevant to economic growth.
