Bank of Korea's Surprise Rate Hike Signals More Tightening Ahead

The Bank of Korea raised its benchmark interest rate for the first time in three and a half years, lifting the seven-day repurchase rate by 25 basis points to 2.75% in a unanimous decision, and signalled that further increases could follow. The move reversed an easing cycle and reflected the central bank's judgment that inflation is likely to remain above its 2% target for a considerable time, while housing prices and household debt stay elevated and brisk growth in Asia's fourth-largest economy fans price pressures. Governor Shin Hyun-song, who took over the central bank earlier this year, has stressed the need to act decisively against inflation. The decision ran counter to the broader global drift toward rate cuts and unsettled markets: the benchmark Kospi tumbled more than 6% as chipmakers Samsung Electronics and SK Hynix slid, tracking losses in US chip stocks. Economists said further tightening looks likely given resilient growth, underpinned by a semiconductor export boom, with the country's exports having surged in recent months. Investors are now focused on how far and how fast the central bank is prepared to move to rein in prices and stabilise the won.
