Determinants of Liquidity Shortage Risk in the Banking Sector in Sudan

Mai Mahmoud Abdo

Abstract


The aim of this study is to investigate the determinants of the liquidity
shortage risk in the banks operating in Sudan, it applies panel logit regression model
for the sample of 25 banks during the period from 2012 to 2017. The dependent variable
is the extreme shortage of liquidity which has been identified by using Value at Risk
(VaR) technique. The independent variables are bank specific and macroeconomic
factors. The bank specific are the banks’ size measured by the total deposits, the
investment variable measured as the total finance extended through the modes of
finance, and the profit approximated by the net profit. The macroeconomic factors are
the black market exchange rate premium and the budget deficit. The findings of the
analysis show that the bank size and the investment are significantly associated with
the liquidity shortage risk but negatively. This implies that the larger the bank, in terms
of total deposits, the lower the liquidity shortage it faces, moreover the investment is
dominated by short term investments, i.e. deferred sales receivables (murabaha
financing). The profit factor is also negative but insignificant, this implies that banks’
profits can be generated via short term investment activities that increase cash holdings
of the banks and reduce liquidity shortage. The black market exchange rate premium is
positive but insignificant whereas the budget deficit is positive and significant. The
positive sign of the black market exchange rate premium implies that increase in the
exchange premium lead to decrease in the local currency value which induce higher
deposit withdrawals by the depositors also banks reduce their holdings of local
currency, and this increase liquidity shortage. The positive sign of the budget deficit
factor implies that the government finances its deficit mainly by resorting to debt
financing (money creation), this lead to increase in inflation rate which cause
depreciation of the value of the local currency, this induce the banks to adjust their
portfolios of local currency holdings as a result the liquidity shortage increases. The
stress testing results reveal that as the black market exchange rate premium increases
the probability of the liquidity shortage risk rises, therefore the Sudanese banking
system is susceptible to high liquidity shortage risk as the black market rate premium
exceeds 50 Sudanese pounds per dollar
