Credit extension in South Africa: an analysis of the impact of interest rates and income levels on the level of household debt

Abstract

The recent growth in the unsecured lending market and the bankruptcy of African Bank Investments Limited have brought to light concerns regarding credit extension and the level of household indebtedness in South Africa. This study seeks to investigate the relevant aspects of credit extension in both the secured and unsecured lending markets by firstly analysing contemporary literature and then conducting a more formal empirical analysis. A VAR model is estimated to examine the effects household disposable income and interest rates have on the level of household debt in South Africa for the period 1995Q1-2015Q3. The empirical results indicate that there is no significant deterministic relationship between household disposable income and household debt. However, the results show that such a relationship does exist between interest rate and household debt. Finally, impulse response functions obtained from the VAR estimation are examined which indicate that both shocks too household disposable income and interest rates effect the level of household debt, but that this effect returns to equilibrium within six periods.
