Central banks can intervene in the currency markets and sell reserves, thereby offsetting the withdrawal of financing by foreign lenders. But intervention requires that the authorities first have both the reserves and the will to abandon (at least temporarily) their hands-off commitment to a floating exchange rate.
中央银行可以干预货币市场，出售外汇储备，从而抵消外国贷款人融资撤出的影响。但干预首先要求当局拥有储备，并愿意放弃（至少暂时放弃）它们不干涉浮动汇率的承诺。并非所有新兴市场中央银行都符合这两个要求。
