South Korean stocks finished lower Wednesday, as rising global oil prices renewed concerns about inflation and the continued push for monetary tightening by major economies. The local currency rose against the US dollar.
The benchmark Korea Composite Stock Price Index shed 18.84 points, or 0.73 percent, to close at 2,563.34, extending a losing streak to the second session. Trading volume was moderate at 415.9 million shares worth 7.55 trillion won ($5.66 billion), with losers outpacing gainers 588 to 288.
The index opened a tad lower and had extended losses on heavy selling by institutions.
Institutions and foreigners sold a net 306.31 billion won and 69.52 billion worth of shares, respectively, while retail investors bought a net 341.45 billion won worth of shares.
Investor sentiment became weak as global oil prices rose to the highest level since late 2022 after the Organization for the Petroleum Exporting Countries Plus vowed to extend supply cuts.
"Inflationary pressures will dash investors' hope for the Federal Reserve to ease its aggressive monetary tightening. Uncertainties regarding macroeconomic circumstances would limit the rise of the KOSPI," Han Ji-young, an analyst at Kiwoom Securities Co., said.
