The benchmark Korea Composite Stock Price Index added 9.36 points, or 0.39 percent, to 2,382.38 in the first 15 minutes of trading.

Overnight, US shares finished higher following last week's deep losses. The Dow Jones Industrial Average jumped 1.58 percent, and the tech-heavy Nasdaq Composite rose 1.26 percent.

The Federal Reserve will begin its two-day meeting on Tuesday, where it is widely expected to deliver a 50-basis point hike, smaller than what it has been.

But investors remain cautious over Fed Chair Jerome Powell's press conference on Wednesday.

The US consumer price index will also come out Tuesday.
