星期三，在央行大幅降低人民币参考汇率之后，美元兑人民币汇率达到6月以来的最高点。

But on Wednesday, the dollar recorded its biggest gain against the yuan since June, after the Chinese central bank sharply lowered the reference rate for yuan movements.

虽然中国去年略微提高了一些其汇率制度的灵活性，但中国央行仍将美元兑人民币汇率的日升降幅度控制在0.3%以内。

Although China moved to a slightly more flexible exchange-rate regime last year, the central bank still restricts the yuan's trading band to a narrow 0.3% each day up or down against the dollar.
