SEOUL, Jan 30 (Reuters) - Most of the Bank of Korea's (BOK) board members said monetary policy needs to stay restrictive for some time to bring inflation back down to the bank's target level of 2% as uncertainties related to supply-side persist, minutes of its Jan. 11 meeting showed on Tuesday.

The BOK held its benchmark rate at 3.50% for an eighth meeting in January and hinted it may pivot towards monetary easing along with its global peers, an outcome correctly forecast by all 38 economists polled by Reuters.
