Seoul shares closed higher Thursday to extend their winning streak to a third day as investors also wait for the US inflation data. The local currency gained against the US dollar.
The benchmark Korea Composite Stock Price Index gained 23.36 points, or 0.81 percent, to 2,891.35.
Trade volume was moderate at 453 million shares worth 14.4 trillion won ($10.4 billion), with gainers outnumbering losers 438 to 414.
Foreigners bought a net 606 billion won, while individuals sold a net 351 billion won. Institutions offloaded a net 81 billion won.
Investors awaited the US consumer price index (CPI) for June due on Thursday, which will set the overall tone for the Federal Reserve's future rate policy.
South Korea's central bank froze its key rate for the 12th straight session at 3.5 percent but hinted that it may move toward an easing policy amid moderating inflation. The Bank of Korea remained cautious over a hasty pivot toward a monetary policy reversal.
"Investors' hope over additional slowdown in inflation and a rate cut remained valid," said Kim Jee-hyun, an analyst from Kiwoom Securities.
