South Korea’s central bank raised its benchmark interest rate by 25 basis points to 3.00% on Thursday, marking back-to-back policy tightening. The Bank of Korea acted to curb persistent inflation pressures driven by strong economic growth, while significantly upgrading its annual gross domestic product growth forecast to 3.3%.
The Bank of Korea delivered a second consecutive rate increase on Thursday, pushing borrowing costs to their highest level since early 2025. In a decision widely anticipated by financial markets, the central bank’s seven-member monetary policy board voted to lift the seven-day repurchase rate by 25 basis points to 3.00%, a move predicted by 18 of 35 economists surveyed in a Reuters poll, and by 14 of 22 economists surveyed by Bloomberg. The BOK last raised rates at consecutive meetings in early 2023, capping a run of seven straight hikes, and Thursday’s decision marked the first back-to-back (consecutive) rate hike
since the COVID-19 pandemic, pushing the base rate into the 3% range for the first time in one year and nine months since November 2024. Governor Shin Hyun-song held a press conference at 0210 GMT following the decision.
The move comes as Asia’s fourth-largest economy expands at a pace that continues to outrun earlier projections, powered primarily by an unprecedented boom in the semiconductor sector.

The Bank of Korea Monetary Policy Board previously convened on the 27th of last month, when the central bank raised the base rate by 0.25 percentage points for the first time in three years and six months, maintaining a 2.75% annual base rate before the latest hike.

Behind the central bank’s tightening cycle lies a powerful economic expansion fueled by global demand for artificial intelligence infrastructure.
Core Inflation and Housing Pressures Drive Policy Turn
While overall consumer price inflation cooled slightly to 2.8 percent in July after rising, underlying price pressures proved sticky. Core inflation in Asia’s fourth largest economy climbed to 2.6% in July, while the headline inflation rate in July cooled slightly to 2.8%, after rising. This core inflation reading hit the highest level last month since December 2023, stripping out volatile food and energy prices and moving the other way while consumer price inflation eased. Korea’s policy turn is recent, as the central bank cut its benchmark rate by a full percentage point between October 2024 and May 2025 before leaving the rate unchanged prior to its recent tightening.
Firm core inflation and a renewed jump in Seoul housing prices strengthened the case for another move, with policymakers having already flagged more tightening in July. The Bank of Korea stated that while South Korea’s economy continued to grow at a stronger-than-expected pace, inflation is likely to remain above the target level for a considerable time.
With growth running hotter than expected on the back of strong exports and a recovering domestic economy, the central bank judged that inflation would remain above its target for a considerable period and that a preemptive response was warranted.
Most experts expected the Bank of Korea to raise its policy rate again at its monetary policy meeting, following a hike last month, operating under the view that the central bank would act preemptively given expectations for strong growth above 3% this year and still-unstable inflation. Some urged caution, however, saying the BOK would maintain its tightening stance while easing the pace in light of recently surging government bond yields, according to a survey of 20 economics and business professors and bond market experts conducted by Seoul Economic Daily.
“Prices are expected to rise above the target level for a considerable period, as the pass-through of cost pressures that have built up continues and demand-side pressures gradually intensify alongside improving income conditions.”

Imbalanced Expansion and Market Strain
The Bank of Korea raised its interest rate by 25 basis points to 3% on Thursday to contain inflation risks fueled by stronger-than-expected economic growth amid an unprecedented semiconductor boom, bringing borrowing costs to their highest level since early 2025. The won nudged higher, adding to gains in the run-up to the decision. The move followed another 25-basis-point increase at the previous meeting in July, which marked the BOK’s first hike since January 2023. The decision came as South Korea’s economy benefits from strong semiconductor exports and the artificial intelligence boom, while higher energy costs stemming from the ongoing Middle East conflict have also contributed to the challenging inflation outlook.
