The effects of global monetary policy and Greek debt crisis on the dynamic conditional correlations of currency markets
This study examines first the effects of financial market turmoil in the fall of 2008 on the conditional correlations between three exchange rate returns (USD to EUR, JPY to USD, USD to GBP), and then the effects of quantitative easing programmes and Greek debt crisis on the entire distribution of estimated correlations. The dynamic correlations have sharply increased during the period that followed the collapse of Lehman Brothers, indicating a financial contagion across currency markets. The quantitative easing programmes of the Federal Reserve and the Bank of England have affected the conditional correlations between the currency pairs. Finally, the Greek debt crisis has emerged as the most significant covariate of the quantile regressions.
