The Bank of Korea has made a significant move by raising its benchmark interest rate for the first time in 3 1/2 years. In a unanimous decision, the Monetary Policy Board voted to increase the base rate by 0.25 percentage point, from 2.50% to 2.75%. This decision effectively reverses the easing cycle that began in October 2024 and marks the bank’s first rate increase since January 2023.
The board cited several reasons for the rate hike, including elevated inflation, housing prices, and household debt. Despite concerns that higher borrowing costs might place excessive pressure on the economy, the bank’s governor, Shin Hyun Song, stated that stronger-than-expected economic growth had reduced these risks.
The bank expects second-quarter growth to exceed its earlier projection of 0.2% from the previous quarter, driven by a surge in exports, particularly in the semiconductor industry. South Korean exports surpassed $100 billion for the first time in June, driven by strong global demand for semiconductors. The bank anticipates the semiconductor boom to spread beyond exports by increasing corporate earnings, investment, wages, and tax revenue, supporting a recovery in domestic demand.
However, the bank also warned that the semiconductor upturn could add to demand-side inflationary pressure. Real gross domestic income rose considerably faster than output in the first quarter as higher semiconductor prices improved South Korea’s terms of trade. This increase indicates that gains from the chip industry are generating income that could flow into consumption and investment.
The central bank emphasized the importance of monitoring semiconductor prices rather than the share prices of chipmakers when assessing their broader effect on the economy. Governor Shin also cautioned that earlier increases in energy costs and the effects of the exchange rate could gradually spread to prices for goods and services.
Consumer prices rose 3.2% in June from a year earlier, remaining above the bank’s 2% inflation target for a second consecutive month. Core inflation stood at 2.5% while an index measuring frequently purchased goods and services remained in the mid-3% range. Short-term inflation expectations stayed in the upper-2% range.
The bank’s decision was influenced by rising home prices in the Seoul metropolitan area, growing household loans, and volatility in the won. Governor Shin stated that the bank would continue responding until it was confident that inflation was moving sustainably toward its target. He declined to commit to a predetermined timetable for another increase, saying future decisions would depend on incoming economic data.
