South Korea’s dollar deposits hit a record high in October.

The Bank of Korea (BOK) said on Tuesday that outstanding foreign currency deposits held by local residents marked 63-point-four billion U.S. dollars as of the end of last month, up four-point-two billion dollars from a month earlier.

U.S. dollar-denominated savings grew about six billion dollars last month to reach a record high 49-point-four billion dollars.

The central bank said that as the Korean currency is strengthening against the U.S. dollar, local exporters are not withdrawing dollars from their accounts.

Chinese yuan-denominated deposits, however, dropped to a 22-month low of seven-point-19 billion dollars.
