The Bank of Korea raised its policy rate by 0.25 percentage points [1] to 2.75% [2] on Thursday.
The move signals a return to a tightening monetary stance to combat persistent inflation and manage the economic impact of strong semiconductor-driven growth.
Governor Shin Hyun-song said the central bank needs to continue raising interest rates to ensure inflation remains anchored to its target. The bank expects the base rate to reach the 3% range [3] by the end of the year.
Shin said the cost of borrowing for homeowners is climbing rapidly. He said mortgage-loan rate ceilings have already surpassed 7% [4], and there is a possibility they could rise to around 8% [5].
The decision comes as the inflation rate remains at 3% [6]. Shin said he will respond until there is confidence that the inflation rate converges stably to the target level.
This policy adjustment also narrows the interest-rate gap between South Korea and the U.S., which decreased from 1.25 percentage points to 1.00 percentage point [7]. The bank is balancing the need to curb domestic price increases against the risk of capital flight and currency volatility caused by the rate differential with the U.S. federal funds rate.
The governor's remarks suggest that the period of rate stability has ended. The bank is now prioritizing price stability over short-term borrowing costs for consumers, despite the pressure on the housing market.
“Mortgage-loan rate ceilings have already surpassed 7% and there is a possibility they could rise to around 8%.”
The Bank of Korea's pivot toward higher rates reflects a struggle to tame inflation that has proven resistant to previous measures. By signaling a trajectory toward 3% and warning of 8% mortgage rates, the bank is intentionally cooling the economy and the housing market. This approach risks increasing the debt burden on households, but it is deemed necessary to prevent the semiconductor boom from overheating the economy and further widening the inflation gap.
