This paper investigates the impact of the money supply in different states of inflation and economic growth in South Africa from 1990 to 2021. The term “states” defines periods of low and high rates of economic variables of interest. Markov-switching dynamic regression (MSDRM) and time-varying parameter structural vector autoregression (TVP-VAR) are used in this paper. The contribution of this paper is not only based on the long run but also on the examination of the impact of the money supply in different states of inflation and economic growth. Moreover, the use of shock accounts for time-varying elasticity. It is found that there is a 0.70% decrease in the gross domestic product for a 1% increase in money supply in state 1, while in state 2, the money supply was insignificant. The money supply had a negative and a positive impact on inflation in states 1 and 2, with rates of 0.05% and 0.35% in the respective states. The money supply had a high multiplier effect on gross domestic product and inflation. More than 5 years were spent in each state for both gross domestic product and inflation, while the transition probability of moving and returning to each state is significant. The trade-off of using the money supply for economic growth and inflation is evident in South Africa. It is recommended that the state of the economy be considered when using the money supply in an effort to stimulate economic growth or stabilise inflation.

Monetary Policy and the Economy in South Africa covers both modern theories and empirical analysis, linking monetary policy with relating house wealth, drivers of current account based on asset approach, expenditure switching and income absorption effects of monetary policy on trade balance, effects of inflation uncertainty on output growth and international spill overs. Each chapter uses data and relevant methodology to answer empirical and pertinent policy questions in South Africa. The book gives new insights into understanding these areas of economic policy and the wider emerging-markets.

The South African Reserve Bank has continued to fulfill its constitutional mandate to protect the value of the local currency by keeping inflation low and steady. This paper provides evidence that monetary policy tightening aimed at maintaining low and stable inflation could at the same time reduce consumption inequality over a 12–18 month horizon, commonly understood as the transmission lag of monetary policy action to the real economy, and similar to the distance between survey waves used in the analysis. In response to “exogenous” monetary policy tightening, the real consumption of individuals at lower ends of the consumption distribution declines relatively modestly, or even increases. With greater reliance on government transfers, thus smaller reliance on labor income, and relatively larger food consumption, these individuals appear to benefit mainly from lower inflation. By contrast, the real consumption of individuals at higher ends of the consumption distribution is more likely to decline due to lower labor income, weaker asset price performance, and higher debt service cost.

This book focuses on income inequality, output-inflation trade-off and economic policy uncertainty in South Africa. Tight monetary and macroprudential policies raise income inequality. Income inequality transmits monetary policy and macroprudential policy shocks to real economic activity. Economic policy uncertainty influences the dynamics in the lending rate margins, inflation expectations, credit, pass-through of the repo rate to bank lending rates and companies’ cash holdings. The trade-off between output and inflation and output growth persistence vary with inflation regimes. Stimulatory demand policy shocks are less effective in high inflation regime. High income inequality raises consumption inequality, which raises demand for credit, but price stability matters in this link. Increased bank concentration raises income inequality, lowers economic growth and employment rate. Elevated economic policy uncertainty lowers output growth, lowers capital formation, reduces credit and raises companies’ cash holdings. Increased companies’ cash holdings reduce capital formation and impact the transmission of expansionary monetary policy shocks to real economic activity. This book shows there is an inflation level within the target band below it which lowers income inequality, while raising GDP growth and employment. Thus price stability, economic policy uncertainty and income inequality matter for the efficient transmission of policy shocks.

This Selected Issues paper studies the growth-inflation trade-off of monetary policy in South Africa. The combination of low growth and stubbornly high inflation expectations for a protracted period has complicated monetary policy decisions. The IMF staff analysis contributes to the ongoing growth-inflation trade-off discussion in South Africa, concluding that there is limited growth trade-off of monetary policy efforts to anchor inflation expectations at a lower level at present. The findings in this note suggest that the South African Reserve Bank should continue its efforts of anchoring inflation and inflation expectations at a lower level because monetary policy lends limited support to growth dampened by structural issues. During the 2010s, domestic demand growth responded little to monetary policy action. The environment of weak growth, low interest rates, and relatively moderate inflation (expectations) could have muted monetary policy transmission. Ultimately, the constraints to economic growth need to be removed. Meanwhile, inflation expectations continue to respond to monetary policy action albeit to a lesser extent. Monetary policy transmission through demand has weakened––demand growth does not systematically respond to monetary policy action nor does core inflation––but the exchange rate and credibility channels appear to remain operational.

This paper describes the main elements of inflation targeting, reviews its pros and cons, and examines the experiences thus far in countries using this framework. It discusses the implications and relative merits of such a framework for South Africa, and concludes that it would be feasible and desirable for South Africa to adopt explicit inflation targeting. Doing so could reduce uncertainties about the Reserve Bank’s objectives and enhance the transparency of monetary policy. However, further experience with the operational aspects of the repurchase system and a refinement of the inflation forecasting framework may be needed before inflation targeting is implemented.
