By combining expansionary open market operations with sales of foreign exchange, the central bank can expand the monetary base without depreciating the exchange rate. Thus, if there is a monetary political business cycle, sales of foreign exchange are especially likely before elections. Our...

Studies of central bank intervention are complicated by the fact that we typically observe intervention only during periods of turbulent exchange markets. Furthermore, entering the market during these particular periods is a conscious "self-selectionʺ choice made by the intervening central...

The paper contributes to understanding the economic dynamics at the zero lower bound and the exchange rate movements under different central bank intervention regimes. It provides a theoretical framework for modeling foreign exchange interventions at the ZLB within a dynamic general equilibrium...

To counter the sharp appreciation of the Swiss franc that set in in the wake of the European sovereign debt crisis, on September 6, 2011, the Swiss National Bank announced to enforce a minimum EUR/CHF exchange rate of CHF 1.20. We find that the simple, though elegant model for the exchange rate...

This study examines foreign exchange intervention based on novel daily data covering 33 countries from 1995 to 2011. We find that intervention is widely used and a highly effective policy tool, with a success rate in excess of 80 percent under some criteria. The policy works very well in terms...

This paper examines the effects of the foreign exchange market interventions by the Bank of Japan on the ex ante correlations between the JPY/USD, EUR/USD, and GBP/USD exchange rates. The correlation estimates used in the analysis are derived from the market prices of OTC currency options. The...

This study considers emerging market central bank interventions motivated by international reserve management. Emerging market central banks use currency intervention as a policy tool against exchange rate movements and accumulate international reserves as an insurance against sudden stops or...

Between September 6, 2011, and January 15, 2015, the Swiss National Bank (SNB) enforced a lower bound of 1.20 on the CHF/EUR exchange rate. In this paper, we view the SNB's commitment to this lower bound as a put option and use a latent likelihood estimation approach to infer (a) where the...
