Is commercial bank lending in South Africa procyclical?

This paper aims to examine the relationship between commercial bank lending and business cycle in South Africa. This paper attempts to know whether commercial bank lending in South Africa is procyclical.

The model assumed that the lending behaviour is related to the business cycle. In this study, vector error correction model (VECM) is used to capture the relationship between bank lending and business cycle to accurately elicit the macroeconomic long-run relationship between business cycle and bank lending, as some banks might slow down bank lending due to some idiosyncratic factors that are not related to the downturn in the economy. This paper uses data from South African Reserve Bank for the period of 1990-2015 using VECM to understand the extent to which business cycle fluctuation can affect credit crunch in the financial system. The Johansen cointegration approach is used to ascertain whether there is indeed a long-run co-movement between credit growth and business cycle.

Results from the VECM show that there are significant linkages among the variables, especially between credit to gross domestic product (GDP) and business cycle. The influence of business cycle is seen vividly after a period of four to five years, where business cycle explains 20 per cent of the variation in the credit to GDP. South African banks tend to change their lending behaviour during upturns and downturns. This result further confirms the assertion in theory that credit follows business cycle and can amplify credit crunch. The result shows that in the long run, fluctuations in the business cycle can influence the credit growth in South Africa.

The impulse analysis result shows that the impact of business cycle shock is very persistent and lasting. This also demonstrates that the shocks to the business cycle result have a persistent and long-lasting impact on credit. This study finds that commercial bank lending in South Africa is procyclical. It is suggested that the South African economy needs forward-looking policies that will mitigate the flow of credit to the real sector and at the same time ensure financial stability.

Most research papers rarely distinguish between the demand side and supply side of credit procyclicality. This report is presented to develop an econometric model that will examine demand side procyclicality. This study adopts more realistic and novel methods that will help in explaining the relationship between bank lending and business cycle in South Africa, especially after the global financial crisis. This report is presented with a concise and detailed analysis and interpretation.
