Bank of Korea Raises Base Rate to 2.75%, Ending a Two-Year Easing Run

The Bank of Korea’s Monetary Policy Board raised its base rate by 25 basis points to an annual 2.75% on July 16, 2026, the first increase recorded in the central bank’s own 24-month rate history and a formal end to the easing cycle that had defined Korean monetary policy since late 2024. The move returns the policy rate to where it stood in early 2025 — but the direction of travel, not the level, is what matters for households and markets.

A Four-Cut Cycle Runs in Reverse

The Bank of Korea’s ECOS statistics database shows how deliberate the path to this decision was. Between October 2024 and May 2025, the board delivered four consecutive quarter-point cuts, taking the base rate from 3.50% down to 3.25%, then 3.00%, 2.75%, and finally 2.50% in May 2025. What followed was a hold of roughly fourteen months — the longest pause in the published record — before the board moved in the opposite direction.

A 25-basis-point step is the board’s standard increment, and reversing course after a long hold rather than extending the cuts marks a genuine turn in the policy stance rather than fine-tuning. Decisions of this kind require at least five of the Monetary Policy Board’s seven members to be present and a majority of those attending to agree, under rules that have governed the body — the Bank of Korea’s rate-setting organ since the central bank’s founding in 1950 — in their current form since the 1998 revision of the Bank of Korea Act.

The Bond Market Got There First

The more telling numbers sit in the market data from the decision date. The overnight call rate stood at 2.74%, hugging the old 2.50% policy rate’s replacement almost exactly — evidence that short-term funding markets had fully priced the hike by the time it arrived. The 91-day CD rate, at 2.91%, was already trading 16 basis points above the new base rate.

The three-year Korean Treasury Bond yield is the outlier: 3.85% on decision day, a full 110 basis points above the freshly raised policy rate. A gap that wide at the three-year tenor is consistent with investors positioning for additional tightening ahead, or at minimum demanding compensation for the risk of it. If the July move were expected to be a one-off, the curve would sit far flatter to the policy rate than it does.

Mortgage Borrowers Were Already Paying More

For Korean households, the squeeze predates the hike. The average rate on newly extended mortgage loans reached 4.36% in June 2026 — the month before the decision — putting new housing credit 186 basis points above even the post-hike policy rate. Lenders, in other words, had been repricing household credit upward while the base rate still sat at 2.50%.

The July increase ratifies that repricing rather than triggering it. The practical question for borrowers over the coming quarters is whether the pass-through steepens: mortgage pricing that ran nearly two percentage points above the policy rate during a hold suggests limited room for lending rates to stand still if the board follows the bond market’s implied path.

Where the Level Leaves Policy

At 2.75%, the base rate sits exactly where it did after the February 2025 cut — a level the board previously treated as a waypoint on the way down. Holding the economy at that same number now, with three-year yields near 3.9% and new mortgage lending above 4.3%, produces meaningfully tighter financial conditions than the identical rate did seventeen months earlier. Whether July proves to be a single corrective step or the first leg of a tightening sequence, the market pricing around the decision shows that lenders and bond investors have already made their assumption clear.
