BOK delivers back-to-back rate hikes, signals gradual tightening ahead

The Bank of Korea (BOK) raised its benchmark interest rate by a quarter percentage point to 3.00% on Thursday, marking a second consecutive hike as inflation remains above target and financial stability risks continue. The seven-member monetary policy board voted to increase the seven-day repurchase rate to the highest level since February 2025.

Economists had predicted this decision, with 18 out of 35 surveyed by a Reuters poll. The BOK also revised upwards the country's growth estimate for the year to 3.3%, from the 2.6% projected in July, while keeping the inflation forecast unchanged at 2.7%. Currently, the median expectation is for one more rate hike in the first quarter of 2027, with a hold through the end of next year.

Analysts anticipate policymakers will focus more on managing financial stability amid an overheating housing market as strong growth feeds into underlying inflation. The BOK's hawkish move aligns with a global central bank environment characterized by significant division, with the Federal Reserve holding restrictive rates and the Bank of Japan taking a cautious stance towards a fragile recovery.

Domestic inflationary pressures and a hot housing market are the primary concerns for the BOK, as geopolitical tensions may push global import costs higher. Investors will closely monitor Chinese and US demand indicators and emerging inflation data in the coming weeks to determine if the BOK's extended tightening cycle becomes the global norm.

Local bond markets had already anticipated the BOK's move, with yields reflecting a market bracing for a prolonged tightening campaign. South Korean policy-sensitive treasury bond futures traded down 0.03 points to 103.29 after the central bank's forward guidance. The updated six-month dot plot, refreshed since May, suggests a policy rate of 3.25% as the most probable outcome for the end of 2026, with 10 of the 21 dots clustered at that level.

Six dots point toward a higher peak of 3.50%, while the remaining five favor holding steady at 3.00%. BOK Governor Shin Hyun-song will address reporters in a news conference at 0210 GMT.
