This study demonstrates with the aid of single equation regression analysis the role global capital markets play in determining the behaviour of the Johannesburg Stock Exchange(JSE ALSI) the Rand/ US dollar exchange rate (ZAR) and long term interest rates in South Africa on a daily basis represented by the All Bond Index (ALBI) or long term government bond yields represented by the R157. It will be shown that since 2005 the state of global equity markets, represented in the study bythe MSCI Emerging Market Index (EM) has had a very powerful influence on the JSE. The EM Index is shown to have had a less powerful yet statistically significant influence on the ZAR while it is also demonstrated and that conditions in global capital markets, and the ZAR have had some weak but statistically significant influence on the direction of long term interest rates in South Africa. It will be demonstrated that movements in policy influenced short term interest rates, have had very little predictable influence on share prices, the ZAR or long termbond yields. The causes as well as the consequences of the ineffectiveness of policy determined interest rates for monetarypolicy are further analysed.
