South Korean stocks closed nearly 2 percent lower Friday to end a three-session winning streak, as investors locked in profits following hotter than expected US inflation. The local currency fell sharply against the US dollar.

The benchmark Korea Composite Stock Price Index dropped 51.92 points, or 1.91 percent, to 2,666.84.

Trade volume was heavy at 575 million shares worth 12.9 trillion won ($9.7 billion), with losers beating winners 557 to 224.

Institutional and foreign selling weighed down the Kospi, which recorded a net 1.06 trillion won sell off, while retail investors purchased local stocks.

The market retreat came after the Kospi's three-session winning streak on Thursday, when it hit an almost 2-year high. Overnight, Wall Street also lost ground after the February producer price index showed US inflation was hotter than expected.

The Dow Jones Industrial Average fell 0.4 percent, and the S&P 500 dropped 0.3 percent. The Nasdaq Composite also shed 0.3 percent.

"The Kospi retreated amid overnight Wall Street losses over the US producer price index for February recording a six-month record high," said Kim Seok-hwan, an analyst at Mirae Asset Securities.

In Seoul, blue chips retreated across the board, with market heavyweight Samsung Electronics dropping 2.69 percent to 72,300 won and No. 2 chipmaker SK hynix sliding 0.43 percent to 161,200 won.

Financial shares also faced corrections following strong gains in the past few sessions. KB Financial fell 3.05 percent to 76,200 won and Shinhan Financial slipped 3.69 percent to 49,600 won.

Battery-related shares also declined amid a lingering worrisome US electric vehicle market outlook. LG Energy Solution slumped 4.21 percent to 398,500 won and Samsung SDI dropped 4.71 percent to 425,000 won.

The local currency ended at 1,330.50 won against the greenback, sharply down 12.90 won from the previous session's close.

Bond prices, which move inversely to yields, fell. The yield on three-year Treasurys rose 3.5 basis points to 3.308 percent, and the return on the benchmark five-year government bonds climbed 4.2 basis points to 3.344 percent. (Yonhap)
