"I think capital flows won't change sensitively even if the (rate) differences widen a little bit," Suh Young-kyung said, when asked at a scheduled event what would happen if rate differences widened further with the United States.

She also said South Korea's monetary policy would be in a tightening mode even if the central bank keeps the policy interest rate unchanged in the coming months.
