Bank of Korea Raises Rate to 3.00% — Its Second Hike in a Row
The Bank of Korea (BOK) raised its Base Rate by 25 basis points on August 27, 2026, pushing the policy rate from 2.75% to 3.00% (Bank of Korea). A basis point is one-hundredth of a percentage point, so 25 basis points equals a quarter-point move. The decision matched what markets were expecting, according to Reuters.
This is the BOK's second consecutive increase. The first came in July 2026, when the central bank lifted the rate from 2.50% to 2.75%, ending a pause on rate hikes that had lasted more than three years (Reuters). The August move brings the rate back to 3.00%, a level the BOK last touched before cutting to 2.75% in February 2025 (Bank of Korea).
The official base rate history shows the path through this cycle: the rate was raised to 2.75% on February 25, 2025; cut back to 2.50% at a subsequent meeting; held at 2.75% as of July 16, 2026; and now sits at 3.00% after the August 27 decision (Bank of Korea). That stop-start pattern preceded the current back-to-back moves.
The shift traces back to May 2026, when the BOK's new governor flagged rising price and currency risks and the bank raised its 2026 inflation forecast (Reuters). At that meeting the BOK held rates steady, but its internal projections were revealing: of nine policymakers' forecasts, seven pointed to 2.75% while two pointed to 3.25%. The board has since moved past the majority view.
Looking ahead, median forecasts reported by Reuters in July 2026 anticipated the BOK raising the rate to 3.25% in the first quarter of 2027 and holding there through at least end-2027 (Reuters). The August hike is consistent with that path, though forecasts depend on incoming data and should not be treated as guarantees. The two dissenting forecasts from May already pointed to a 3.25% endpoint; whether the committee's center of gravity shifts toward that view will depend on inflation data and pressures on Korea's external balance in the coming months.
The broader context here is what matters for market participants. The May projections placed the majority view at 2.75%, which the board has now exceeded. That the BOK moved past its own central forecast and toward the more aggressive end of the range within a single quarter is the more notable signal from this decision. It narrows the distance to the 3.25% terminal rate that consensus expects for early 2027. The compression of the timeline, rather than the 25 basis points themselves, is what warrants attention.
For Korean households and businesses, a 3.00% Base Rate feeds directly into floating-rate loan pricing. The pass-through to loans tied to KORIBOR (the Korea Interbank Offered Rate) and COFIX (the Cost of Funds Index) typically takes one to three months, squeezing borrowers' ability to service debt at a time when debt-service ratios are already high. The cumulative 50 basis points of tightening since July adds roughly KRW 500,000 per month for every KRW 100 million of floating-rate debt, a cost that compounds quickly for leveraged borrowers.
The wider picture is an Asian central bank that paused longer than most peers, cut rates in early 2025, and is now moving with visible urgency. The May pivot, the July hike ending a three-year pause, and now a second consecutive move all point to a committee that has reoriented its priorities toward persistent inflation and currency risk rather than soft domestic demand. Whether that reorientation extends to a third hike depends on data the BOK has not yet seen, and the August statement offers no explicit forward guidance beyond what the internal projections and the Reuters survey already disclosed.
