The local stock market remained in a tight range on strong foreign sell-offs, as expectations of a fast economic rebound raised inflation concerns in global markets, pushing up commodities and U.S. Treasury yields.

Overnight, the Nasdaq dipped 2.46 percent as tech stocks, sensitive to high inflation, retreated.

“The market is anticipating some positive guidance from (U.S. Federal Reserve Chairman Jerome) Powell,” Shinhan Investment analyst Choi Yoo-joon said. “If Powell comments on the recent bond yields hike, it could calm the markets in the short run,” he said.

The U.S. Federal Reserve is to hold its monetary policy meeting on Tuesday and Wednesday (U.S. time).
