With inflation currently at 3.2%, above the central bank's 2% target, and the Korean won down around 1.8% against the dollar so far this year, the BOK is unlikely to change its hawkish stance anytime soon.

However, Governor Rhee Chang-yong said in a New Year speech the BOK would adopt a "policy mix" to bring down inflation and needed to prepare for the possibility of financial uneasiness that may be triggered by monetary policy remaining restrictive.

All 38 economists in the Jan. 3-8 Reuters poll expected the BOK to leave the base rate unchanged at 3.50% on Jan. 11.

"They (the BOK) will freeze the policy rate for the time being, but are likely to loosen their stance a bit," said Stephen Lee, chief economist at Meritz Securities Research Center.

"The most likely scenario for the BOK's pivot will be in 2H24. By then, both headline and core inflation will fall below 2.5%...increasing the need for policy support related to a soft-landing. The problem can be bigger if interest rates remain higher throughout the year."

According to the central bank, inflation was expected to return to its target in late 2024.

Median forecasts showed interest rates remaining on hold until end-Q2, followed by 25 basis-point cuts in each of the remaining two quarters of this year, unchanged from a November poll.

Among those who had forecast through Q3, nearly half or 11 of 24 economists expected interest rates to fall to 3.25%. While 10 saw them at 3.00%, two predicted no change at 3.50% and one saw rates at 2.75%.

If realised, the BOK's easing cycle for this year would be shallower than what is expected from the U.S. Federal Reserve, one of Korea's largest trading partners.

"There is not enough reason for the BOK to begin easing earlier. Healthier exports should mitigate weaker domestic demand following the BOK's restrictive monetary policy while the government's fiscal policy can provide selective support for the weaker segments of the economy," noted Jin Choi, economist at HSBC.

"We think the Board will likely retain its cautious stance mainly for two reasons. Firstly, we are not in for fast disinflation ahead. Moreover, the BOK has been stressing the risk of accumulated cost pressures faced by various domestic producers."

Economic growth will improve this year, averaging 2.1% in 2024 from 1.4% last year, BOK estimates showed.
