The value of the Chinese yuan has been falling since the U.S.-China trade war began in earnest this month. On Aug. 1, the yuan’s value fell to 6.82 against the U.S. dollar.
The central parity of the yuan has depreciated by more than 4 percent since the beginning of the year, while its value against the dollar has dropped by 8 percent since April—the worst four-month fall on record.
