The Bank of Korea raised its benchmark interest rate by 25 basis points to 3.00% on August 27, 2026, the highest level since February 2025. This marks the second consecutive rate increase following a similar 25 basis point rise in July 2026 as inflation remains above target and economic growth accelerates [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].
The seven-member monetary policy board voted 6 to 1 in favor of the increase, with one member opposing keeping the rate unchanged [7, 8, 11, 10]. Governor Shin Hyun-song described the back-to-back hikes as "not a routine operation," but a strong signal that the central bank prioritizes curbing inflation above its 2% target and managing financial stability risks [10].
South Korea’s core inflation stood at 2.6% in July 2026, while headline inflation measured 2.8%, both above the Bank of Korea’s target [3, 6, 9]. The persistent inflation risks are linked to an unprecedented semiconductor boom and export strength driven by global AI demand, contributing to robust economic growth [1, 4, 5, 6, 7]. Responding to this, the Bank raised its 2026 GDP growth forecast from 2.6% in July to 3.3%. It also lifted the 2027 growth estimate from about 2.1% to 2.9% [1, 5, 6, 7, 11, 9].
Following the rate decision, the Korean won strengthened to approximately 1377.40 per US dollar, recovering from a 17-year low earlier in the year [5, 6]. The Bank of Korea also warned of ongoing financial stability challenges and signs of overheating in Seoul’s housing market and nearby regions [1, 3, 7, 10].
Market economists were divided before the announcement. A Reuters poll showed 18 of 35 economists expected a 25 basis point hike, though some surveys reflected mixed expectations [1, 8, 10]. Kong Dong-rak, an economist at Daishin Securities, said, "I now think the terminal rate is 3.50%, higher than my earlier projection of 3.25% as the economy could expand as much as 3.5% this year" [1].
Looking ahead, the Bank of Korea is expected to raise rates at least once more in the first quarter of 2027, potentially pushing the terminal rate to 3.50% [1, 5, 7, 11, 10]. Meanwhile, Bank of Japan deputy governor Ryozo Himino noted the need for timely rate hikes to manage inflation risks around 2%, signaling possible BOJ rate changes as early as September [12, 11]. Shotaro Mori, senior economist at SBI Shinsei Bank, said, "The September meeting is likely to be live" given the hawkish stance [12].
