We've seen the yuan go stronger even as the dollar had a big move up in its last trading session. That's abnormal and it's probably because the authorities are trying to use it for political effect.
Authorities are opting for direct monetary policy instruments instead of allowing faster appreciation of the yuan to achieve the tightening effect. The pace of yuan appreciation will likely be rather moderate in the coming weeks.
The yuan has moved more closely in sync with the overall performance of the region's currencies against the US dollar.
