The Bank of Korea raised its benchmark seven-day repurchase rate by 25 basis points to 3.00% on Thursday, extending its tightening cycle for a second straight policy meeting. The move brought the policy rate to its highest level since February 2025.
The central bank also released updated forecasts showing its 2026 GDP growth estimate was revised up sharply to 3.3%, from 2.6% in May. That upgrade stood out as one of the main points from the meeting.
Chip exports are supporting growth while feeding inflation
In its post-meeting statement, the Bank of Korea said the latest back-to-back rate increases were driven in large part by stronger inflation pressure tied to the semiconductor cycle, which has lifted income.
Official figures cited in the report showed real GDP rose 0.6% quarter over quarter in the second quarter, three times the central bank’s earlier 0.2% forecast. July core inflation came in at 2.6% year over year, remaining above the bank’s 2% target.
As framed in the report, stronger chip exports are boosting household purchasing power, while also adding to upward pressure on prices.
July’s first hike triggered a sharp market reaction
This was not the Bank of Korea’s first move this year. On July 16, it delivered its first rate hike in three and a half years, ending the pause that had been in place since January 2023.
On that day, the KOSPI fell more than 6% and trading was briefly halted by a circuit breaker, underscoring how sharply markets reacted to the policy shift.
Governor Rhee Chang-yong was quoted at the time as saying, 「Inflation, economic growth, the exchange rate, and financial stability risks all point in the same policy direction」, adding that rates would keep rising until there was enough confidence that inflation would return to 2%.
Household debt adds to the policy dilemma
A Reuters survey of 35 economists previously found that only 18 expected the Bank of Korea to raise rates by 25 basis points at this meeting, showing that even with the direction of policy in focus, views on the timing and pace remained split.
That divide reflects the central bank’s current dilemma. It is trying to contain financial risks linked to record-high household debt and a heated housing market, while also preserving growth momentum supported by the semiconductor upcycle. A move that is too aggressive could cool the economy earlier than intended.
At the same time, a stronger U.S. dollar and rising expectations for Federal Reserve tightening have added pressure on the won and on cross-border capital flows. The decision was made by the Bank of Korea’s seven-member Monetary Policy Board. Markets are now watching how policymakers see the rate path over the next three months and whether they will still leave room for more tightening after September.
Crypto markets are watching South Korean liquidity conditions
For crypto investors, the policy turn matters for a straightforward reason: South Korea is one of the world’s three largest retail cryptocurrency trading markets. Order flow on Upbit and Bithumb can directly affect BTC and ETH pricing and trading appetite during Asian hours.
With the central bank now clearly in tightening mode, higher funding costs tend to hit risk assets early, and cryptocurrencies are part of that group.
At the same time, the report said South Korea’s so-called kimchi premium has recently moved back into positive territory after a long stretch of negative readings, recovering to about 1.5%. That suggests local buying demand has not faded despite the rate hikes. Because South Korea has long maintained strict capital controls and a real-name KYC system, local crypto prices have often traded somewhat separately from international markets. The direction of the kimchi premium is often treated as a gauge of South Korean retail sentiment.
