Summary Soft but firm Exchange rate bands with a longer horizonExchange rate intervention by monetary authorities should defend a band not for the spot exchange rate, but for a moving average of its recent values. This target zone is soft, in that it allows greater short-run flexibility, but also rigorous: it still precludes any sustained easing of monetary policy. In comparison with conventional hard target zones for the spot exchange rate, we find considerable advantages for the rule we propose. In particular, without compromising long-run discipline, it increases resilience against speculative attacks, especially when shocks to exchange rate fundamentals are transitory.— Leonardo Bartolini and Alessandro Prati
