The local currency further weakened late Friday morning from the earlier session, jolted by heightening tension on the peninsula following the exchange of cross-border artillery fire between the two Koreas, analysts said.
The Korean won was changing hands at 1,192.70 won against the U.S. dollar as of 11:20 a.m., down 7.4 won from Thursday's close.
The won declined to the 1,190.00-won mark again, nine days after it dipped to that level following the consecutive yuan devaluations by China's central bank.
Dealers said the latest military provocation by Pyongyang pushed the won down, although its falling pace has been limited.
The Federal Reserve's July minutes, which stated lingering concerns about the economy, sapped expectations for a September rate hike, sending the dollar lower Thursday (U.S. time).
The local stock market also continued to trend in negative territory, with the benchmark KOSPI retreating 29.38 points, or 1.53 percent, to 1,885.17 as of 11:20 a.m. The tech-laden KOSDAQ slumped 3.1 percent. (Yonhap)
