Yuan Appreciates More Than 3% In Real Terms
The fact that inflation is accelerating and is higher than in the United States also implies that the real exchange rate of the yuan is continuing to rise even though the nominal exchange rate haven't increased so much. While the U.S. August inflation numbers aren't available yet, the inflation rate was 1.2% in July.
Assuming this stays unchanged in August, this implies an inflation differential of 2.3%. Together with the 1% nominal appreciation since the slight June modification of Chinese currency policy, this implies a real appreciation of 3.3% during the latest year.
While it is up to Chinese policy makers to decide to what extent this will involve nominal appreciation, real appreciation is over a longer period inevitable, not because of posturing by U.S. politicians, but because of the Penn effect and because high money supply growth will in the long run follow from high reserve growth caused by currency intervention.
However, since the Penn effect involves a relative price increase of non-tradable goods and services over tradables, and since it is the prices of tradable goods and services that matters for international competitiveness, this may not mean that Chinese competitiveness will decline very much.
