BOK Raises Benchmark Rate to 3.00%, Signals Scope for Further Tightening

The Bank of Korea raised its benchmark interest rate to 3.00% and signaled it could tighten policy further.

On Aug. 27, the BOK’s Monetary Policy Board voted to raise the base rate by 25 basis points to 3.00% from 2.75%. The board said the economy is sustaining stronger-than-expected growth, supported by robust exports and a recovery in domestic demand. With inflation expected to remain above target for an extended period, it said a preemptive response was needed to keep price pressures from spreading.

The board also explicitly left open the possibility of additional rate increases. “Future monetary policy will determine the timing and pace of further hikes while closely monitoring inflation, growth and financial stability conditions,” it said. The statement indicates the central bank is not immediately shifting to a pause after this increase and may tighten further depending on economic data.

The BOK also sharply raised its growth forecasts. It now projects the economy will expand 3.3% this year and 2.9% next year, up from its May forecasts of 2.6% and 2.1%, respectively. The central bank expects exports and investment to keep increasing on strong semiconductor demand, while improving income conditions gradually broaden the recovery in consumption.

Inflation also underpinned the case for further tightening. Headline consumer inflation slowed to 2.8% in July, but core inflation, which excludes food and energy, accelerated to 2.6% as price gains widened in personal services and durable goods. The BOK forecasts consumer inflation at 2.7% this year and 2.3% next year, with core inflation at 2.5% in both years. Those core inflation forecasts were raised from 2.4% for this year and 2.3% for next year in May.

The central bank said accumulated cost pressures continue to feed through to prices, while demand-side pressures are also building as income conditions improve. It expects inflation to remain above target for a considerable period. The inflation path will depend on global oil prices, exchange-rate moves, the pace of domestic-demand recovery and the extent of wage growth.

The BOK also said tighter policy is still needed from a financial-stability perspective. It said risks linked to strong gains in home prices in the Seoul metropolitan area and a substantial increase in household debt should continue to be monitored.

Six members of the Monetary Policy Board backed the rate increase. Board member Hwang Geon-il dissented, arguing that keeping the benchmark rate unchanged at 2.75% would be preferable.
