China Regulator Said to Ask Banks for More Currency Trading Data

China’s financial regulator asked some banks to report additional foreign-exchange transaction data on top of its routine quarterly requests, according to people familiar with the matter, adding to earlier surveys on currency trading and capital flows.

The National Administration of Financial Regulation last week ordered at least three commercial banks to report a detailed set of data, including quarterly and annual spot and derivative currency trading volume, said the people who asked not to be named as they aren’t authorized to discuss the matter publicly.
