    Effect of exchange rate volatility on capital flows in South Africa
    (2015) Ng'ambi, Muma
    e period 2000:q1 – 2014:q3 in South Africa. In addition, the paper examines the impact that the exchange rate volatility exerts on the different forms of capital flows. Consequently, the aim of the study is to examine whether the volatility in the exchange rate is a significant determinant of foreign investor capital into South African markets as well as to empirically establish the dynamic relationship that can be observed between capital flows and exchange rate volatility. A trade weighted exchange rate was constructed from which the conditional variance GARCH (1,1) model is applied to estimate exchange rate volatility. The findings from the multiple regression analysis reveal that exchange rate volatility has a statistically significant negative impact on the aggregated capital flows to South Africa. Using the bi-variate vector autoregressions (VARs), the Granger-causality test, impulse response and variance decomposition, the results show there is a dynamic interrelationship between exchange rate volatility and the aggregated and disaggregated capital flows. Furthermore, the VAR specifications results reveal that portfolio flows exhibits a strong bi-directional causality with exchange rate volatility as well as explaining a significant percentage of innovations in exchange rate volatility. This suggests that fluctuations in the exchange rate can be explained by portfolio flows into South Africa’s capital markets. The recommendations for authorities resulting from the findings include, a monetary policy that mitigates the rand exchange rate volatility in an effort to attenuate the adverse subduing effects it has on capital flows in South Africa. Further broadening financial instruments and derivatives available for investors to hedge against exchange rate volatility and a meticulous management of portfolio flows is imperative to ensure prevention of its destabilizing effect on the exchange rate.

    Monetary policy transmission and house prices, a VAR approach: a case study of South Africa (1994 to 2011)
    (2013-08-21) Mutsvunguma, Priscilla Tatenda
    We analyse the role of financial and macro-economic variables in the conduct of monetary policy, particularly the role played by monetary policy in the house price boom of the early 2000s. The analysis is performed in the setup of a New Keynesian open economy. We estimate a five variable Recursive Vector Autoregressive model consisting of the short term interest rate, house prices, inflation, output and the exchange rate. Quarterly data from 1994 to 2011 was inputted in Eviews (6) to run the model. We find a significant causal relationship between the short term interest rate and house prices; the impulse response results show an instant response of house prices to a shock in monetary policy. We conclude that the house price boom of the early 2000s was partially attributed to an overreaction to a shock in monetary policy. We also find evidence of exchange rate pass- through to the consumer price index as in (Mishkin, 2008).We conclude that perhaps monetary policy should take cognisance of asset price fluctuations and exchange rate volatility in determining the policy instrument
