Exchange rate overshooting

3 key takeaways:

• Exchange rate overshooting occurs when a currency’s value initially moves beyond its long-run equilibrium level before stabilizing.
• This phenomenon is often driven by changes in monetary policy, such as interest rate adjustments, which affect capital flows and currency demand.
• Understanding overshooting helps in predicting short-term exchange rate movements and assessing the impact of economic policy changes.

What is exchange rate overshooting?

Exchange rate overshooting is a concept in international finance where the short-term response of an exchange rate to an economic shock is more pronounced than its long-term adjustment. When an economic event, such as a change in monetary policy, occurs, the exchange rate might initially move significantly beyond its new equilibrium level before gradually settling back to a stable value.

This behavior is largely explained by the dynamics of asset markets and goods markets, which adjust at different speeds. Financial markets, where exchange rates are determined, can react very quickly to new information, while goods markets adjust more slowly. As a result, exchange rates can “overshoot” their long-run equilibrium in the short run before stabilizing as the goods markets catch up.

How does exchange rate overshooting work?

Exchange rate overshooting can be illustrated through the following process:

1. Monetary Policy Change: Suppose a central bank unexpectedly raises interest rates to combat inflation. Higher interest rates attract foreign capital, increasing demand for the domestic currency.
2. Immediate Exchange Rate Reaction: In the short term, the exchange rate appreciates significantly as investors move funds to take advantage of higher returns. This initial reaction is often stronger than the long-term effect due to the rapid response of financial markets.
3. Adjustment Phase: Over time, the goods market begins to adjust to the new interest rate environment. The higher interest rates may lead to reduced spending and investment, slowing down economic activity.
4. Long-run Equilibrium: As the goods market adjusts, the exchange rate gradually moves back towards its new long-run equilibrium level, which reflects the underlying economic conditions after the policy change.

This overshooting process highlights the importance of distinguishing between short-term and long-term exchange rate movements when analyzing the impact of economic policies.

Key features of exchange rate overshooting:

Exchange rate overshooting provides several important insights:

• Market Dynamics: It underscores the different adjustment speeds of financial and goods markets, explaining why exchange rates can be highly volatile in the short term.
• Policy Impact: Understanding overshooting helps policymakers anticipate and manage the immediate effects of monetary policy changes on exchange rates, ensuring that short-term volatility does not undermine economic stability.
• Investment Decisions: Investors can use knowledge of overshooting to make informed decisions about currency positions, taking advantage of temporary misalignments in exchange rates.
• Economic Forecasting: Economists and analysts incorporate overshooting into their models to improve the accuracy of exchange rate forecasts, especially following economic shocks.
