With inflation high and financial risks unresolved, the Bank of Korea has raised interest rates to a three-year high.

On Thursday, the Bank of Korea announced it would raise its benchmark interest rate by 25 basis points to 3% , marking the second consecutive rate hike , in response to stronger-than-expected economic growth and persistent inflationary pressures above the target level.

The Bank of Korea stated that today's interest rate decision was not unanimous, with one of the seven members of the Monetary Policy Committee voting to keep rates unchanged.

At the same time, the Bank of Korea significantly raised its 2026 GDP growth forecast to 3.3%, a substantial increase from the 2.6% forecast in May, further reinforcing the signal of continued monetary policy tightening.

The Bank of Korea stated that it expects inflation to remain above the target level for a considerable period of time and pledged to continue implementing monetary policies that can stabilize CPI inflation at the target level.

The central bank also pointed out that, driven by sustained high growth in exports and investment, the domestic economy will continue to maintain strong growth, and the pace of consumption recovery will gradually accelerate.

This rate hike marks the bank's second tightening of interest rates since July, which was the first such increase since January 2023. Following the decision, the Korean won strengthened against the US dollar, while South Korean government bond futures fell.

The suspense surrounding the interest rate decision continues until the very end.

Prior to the announcement of this resolution, market expectations were clearly divided, and the outcome was almost undecided.

According to a Bloomberg survey of 22 economists, 14 expect the central bank to raise interest rates by 25 basis points at this meeting, while 8 expect it to remain unchanged; a survey by some South Korean media outlets shows that the two groups' expectations are more closely aligned.

Those who support pausing interest rate hikes previously cited the recent sharp appreciation of the Korean won as a reason to reduce the urgency.

Since the July meeting, the South Korean won has strengthened significantly, breaking through the 1,400 won per dollar mark and outperforming all similar Asian currencies this month. As of Tuesday afternoon in Seoul, the won was trading at approximately 1,383, near its strongest level in 11 months, which theoretically helps to curb imported inflation.

However, stronger economic fundamentals ultimately supported the decision to raise interest rates. The Korea Development Institute, a state-owned think tank, predicts that the South Korean economy will expand by 3.2% this year, and private economists surveyed by Bloomberg even expect the growth rate to be faster.

The path of inflation is subject to multiple uncertainties.

The Bank of Korea maintained its 2026 CPI growth forecast at 2.7%, consistent with its May forecast.

Nevertheless, the central bank clearly pointed out that the future trend of inflation faces high uncertainty, mainly related to oil price fluctuations, exchange rate trends, the pace of domestic demand recovery, and the degree of transmission of wage increases.

Previously, the market expected inflation forecasts to be revised upwards further from 2.7% in May, citing reasons including rising oil prices, the depreciation of the Korean won since the beginning of the year, and the transmission effect of the semiconductor boom on investment and consumption.

The central bank also named several financial stability risks, including the fact that housing prices in the Seoul metropolitan area have risen for 81 consecutive weeks, the continued expansion of household debt, and the increase in leveraged stock investments.

The South Korean government has proposed imposing higher taxes on high-priced and investment properties as part of a broader measure to curb housing demand.

Market attention shifts to the path of subsequent tightening.

With the interest rate hike now in effect, investors' attention has quickly shifted to forward guidance on the policy path. This update will be the first to show a six-month dot plot since May, and the market will be looking for signs of further tightening.

Bank of Korea Governor Shin Hyun Song previously stated that maintaining a tightening bias is necessary given that inflation continues to exceed the target, economic growth is trending strongly, and financial stability risks remain.

The minutes of the July meeting showed that committee members generally agreed that monetary policy should continue to tighten, but several officials said that the timing and pace of subsequent actions should be determined by subsequent data.

The Bank of Korea also emphasized that the extent of expansion in the chip sector, developments in the Middle East, and changes in the global trade environment remain the main uncertainties for the economic outlook, and it will continue to assess inflation, the domestic economy, and financial stability.
