The Declining Impact of Exchange Rate Volatility on Trade

The introduction of the euro in 1999 eliminated exchange rate volatility between the members of the eurozone. Despite the elimination of currency risks, trade flows within the eurozone hardly increased (Bun and Klaassen in Oxf Bull Econ Stat 69:473–496, 2007, Santos Silva and Tenreyro, 2009). Using a standard gravity model, we find that nominal exchange rate volatility has had a negative effect on trade before 1985 but that this effect disappeared in later years, coinciding with the introduction and rapid diffusion of over-the-counter currency swaps. The estimated coefficient for the euro dummy does not change when we include nominal exchange rate volatility as an additional regressor. This confirms our finding that the impact of exchange rate volatility on trade has been small in more recent years.
