It is just over a year since Switzerland surprised many when it announced, and strictly implemented, a threshold beyond which its currency would not be allowed to appreciate against the euro. And, remember, the country’s operating model for centuries has been to provide a safe haven for foreign capital.
以瑞士为例，该国在一年前就令人惊讶地宣布（并严格执行）了一个阈值——如果超过这个阈值其货币就不能继续对欧元升值。而请留意这个国家好几个世纪以来的运作模式就是为外国资本提供安全的港湾。
