From July 2005 until this past December, China’s renminbi appreciated steadily. So why, if China was still running a decent current-account surplus and a long-term capital surplus, did the currency suddenly depreciate, forcing the PBoC to intervene to prevent it from falling further?

BEIJING – From July 2005 until this past December, China’s renminbi (RMB) appreciated steadily. But then the RMB fell unexpectedly, hitting the bottom of the daily trading band set by the Peoples’ Bank of China (PBoC) for 11 sessions in a row. Though the RMB has since returned to its previous trajectory of slow appreciation, the episode may have signaled a permanent change in the pattern of the exchange rate’s movement.
