The Korea Composite Stock Price Index (KOSPI) rose 45.43 points, or 1.86 percent, to 2,492.81 points in the first 15 minutes of trading.
Overnight, US shares closed higher after the Fed hiked the key rates by 0.75 percentage point, the largest increase since 1994, to tame high-flying inflation.

The Fed also signaled it could raise the rates by the similar margin next month to bring inflation under control.
The Dow Jones Industrial Average rose 1.0 percent, and the tech-heavy Nasdaq composite advanced 2.5 percent.
On Wednesday, the South Korean index fell to a 19-month low to extend its losing streak to a seventh session amid uncertainties about the US central bank's monetary policy path and concerns over a global economic recession.
