如果人民币每天贬值（比如）2 % ， 那么不消多久，其币值就会跌去20 % — —足以引发恐慌，造成汇率混乱，不管经济基本面如何。
If the renminbi were to depreciate by, say, 2% every day, it would take very little time for the currency to lose 20% of its value – enough to cause a panic and, regardless of the country’s economic fundamentals, send the exchange rate into a tailspin.
