Of course, a central bank’s mandate is price stability in the national economy that it serves, and price stability is influenced by exchange rates. So a case can be made that central banks should have the power to intervene in foreign-exchange markets, and that this power should – at least in times of crisis – include commitments to foreign central banks to provide unlimited liquidity in the domestic currency.
当然，央行的使命是所在国国民经济的价格稳定，而价格稳定受汇率的影响。因此央行应该有权力干预外汇市场的看法不无道理，并且这一权力应该——至少在危机时期应该——包括向外国央行承诺无限制供应本币流动性。
