This paper examines the effect of foreign exchange (FX) trading volume on volatility using high-frequency data.
FX trading volume is a key factor in volatility. Estimation results from econometric models reveal a significant impact of third-party trade volumes on the volatilities of original currency pairs. Though the United States dollar (USD) exerts sizeable effect through third-party channels, currency pairs without USD linkages also have impact, calling renewed attention to using regional cooperation in mitigating volatility as compared with major FX trading partners.
