Market expected a freeze, but Bank of Korea delivers 'surprise' rate hike

The Bank of Korea's Monetary Policy Committee surprised the market on August 27 by raising the benchmark interest rate by 0.25 percentage points to 3.00%, a move that defied widespread expectations of a rate freeze.

According to a survey conducted by the Korea Financial Investment Association between August 13-19, involving 100 domestic bond experts from 49 institutions, a significant majority, 79%, predicted that the committee would freeze the rate at its August meeting. Only 20% anticipated an increase. While factors like upward revisions to economic growth forecasts, inflationary pressures, and rising household debt supported a rate hike, experts believed that stabilizing exchange rates and increasing market interest rates favored a freeze.

In contrast to the domestic experts' consensus, international investment banks (IBs) were more aligned with the Bank of Korea's decision. Many major financial groups, including DBS, Mitsubishi UFJ Financial Group, and Citigroup, had predicted that the Bank of Korea would raise rates again, following the 0.25 percentage point increase in July. Goldman Sachs and Barclays, while presenting a rate freeze as their base scenario, acknowledged that the odds of a hike versus a freeze were nearly even.

The surprise decision highlights a divergence in economic outlooks between domestic market participants and international financial institutions. The Bank of Korea's move signals a continued focus on managing inflation and financial stability risks, even amidst concerns about economic growth and household debt.
