Bank of Korea Gov. Lee Ju-yeol on Monday projected more volatility in the global financial market this year amid mixed policy directions in major economies.

Lee also said the country needs to brace for a possible financial risk as economies around the world are becoming increasingly connected, making them more susceptible to unexpected danger.

The top central banker's remarks come as the Fed is expected to start hiking its key interest rate while Japan and the eurozone stay with accommodative rate policies.

On this year's economic growth, Lee said situations have changed since the central bank made its last outlook revision in October.

"While there seem to be some difficulties, situations have changed from three months earlier," the governor said, hinting at an outlook revision this month.

In a December press conference following a rate freeze, Lee had said that it "seems inevitable to revise down the inflation outlook," citing falling oil prices.

Regarding the weakening oil prices, Lee said, its positive effect is bigger than the negative effect. (Yonhap)
