- Description
- This study seeks to investigate the trends and interactions of market volatility as a source of instability in the South African financial markets. Financial instability can be manifested in the form of banking and currency crisis, institutional failures and extreme asset price volatility. This study, however, focuses on a single aspect of financial instability - asset price volatility. Asset price volatility reflects changes in market expectations as investors react to such changes, and thus on its own is not necessarily a source of instability. However, volatility spillovers can propagate volatility shocks across the market, increasing the risk of widespread instability. Using a combination of graphical and trend analysis as well as more formal estimation techniques, the study examined volatility in the stock, money and foreign exchange markets. To obtain estimates of market volatility, the study experimented with various volatility models that include the GARCH, TARCH and EGARCH. An analysis of volatility interactions and the transmission of volatility shocks across the market is crucial to understanding financial instability. To examine volatility interaction and the transmission of volatility shocks, a VAR model was estimated. This framework allowed us to examine the propagation of shocks across the markets. Volatility in the financial markets was found to be highly persistent and in the case of exchange rates, volatility was also characterised by an increasing trend. Significant linkages between the financial markets were found. The links also extended to the volatility relationship as evidenced by significant volatility spillovers across the markets. While volatility spillovers from the money market were found in the stock market and the foreign exchange market, no volatility spillovers from these markets were found in the money market. Thus the money market was identified as the major source of volatility spillovers and shocks in the financial markets. These results highlighted the role of monetary policy in the financial system, specifically the need to make monetary policy stable and predictable to ensure that interest rate shocks are not an additional source of instability.
