SEOUL, Dec. 13 (Yonhap) -- South Korean stocks retreated after a two-day increase Thursday, as investors worry rising inflation in the United States could hasten the Federal Reserve's tapering move. The Korean won rose against the U.S. dollar.
The benchmark Korea Composite Stock Price Index (KOSPI) fell 10.39 points, or 0.35 percent, to close at 2,962.09 points.
Trading volume was moderate at about 597 million shares worth some 11.3 trillion won (US$9.5 billion), with losers outnumbering gainers 449 to 412.
Institutions sold a net 304 billion won and retail investors offloaded 91 billion won, while foreigners bought 369 billion won.
Stocks got off to a muted start as the U.S. consumer price index increased 7 percent in December, the highest on-year jump in almost four decades.
Overnight, the tech-heavy Nasdaq composite inched up 0.23 percent and the Dow Jones Industrial Average rose 0.11 percent, as the inflation woes have been largely on stock prices.
The Seoul stock market increasingly lost ground in the afternoon, joining the other Asian stock markets.
"The latest keyword in the market is the pace of the Fed's tapering and rate hikes," Eugene Investment & Securities analyst Huh Jae-hwan said.
"Investors are not buying into a radical pace of tapering, but the high inflation rates will need some time to cool. Stocks lacked momentum for additional gains," he said.
In Seoul, market bellwether Samsung Electronics lost 1.27 percent to 77,900 won, while No. 2 chipmaker SK hynix added 0.78 percent to 129,500 won.
LG Electronics surged 6.2 percent to 145,500 won after reports that it will supply an infotainment system to Mercedes-Benz's EQS model.
Internet portal operator Naver moved up 0.72 percent to 348,000 won, and financial heavyweight KB Financial grew 0.65 percent to 62,300 won.
Among losers, leading carmaker Hyundai Motor dropped 0.71 percent to 210,000 won, and electric car battery maker LG Chem declined 2.33 percent to 755,000 won.
The local currency closed at 1,187.5 won against the U.S. dollar, up 3 won from the previous session's close.
