The Effects of Foreign Currency Derivatives on the Monetary Policy Exchange Rate Channel in China

Abstract

This paper examines changes in the monetary policy exchange rate channel in the presence of foreign currency derivatives (FCD) markets in China. Initially a theoretical macroeconomics model incorporating the exchange rate risk hedging is presented, and this is followed by an empirical test. A theoretical model implies that with more firms using foreign currency derivatives to hedge the exchange rate risk, the effect of the exchange rate on the net exports will be weaker and may even be reversed. The empirical section uses Structure Vector Autoregression (SVAR) models with China's monthly macro data over the 2000–2013 period to assess the impact of the FCD market on the exchange rate channel. Empirical support for the changes in the exchange rate channel transmission is found. By impulse response function (IRF) analysis, with the emergence of the domestic FCD market in China, in the long run the probability becomes higher that the negative effect of RMB appreciation on China's net exports to the US is reversed; meanwhile the negative effects of RMB appreciation on the overall net exports and the net exports to the EU become gradually weaker on average.
