The Bank of Korea increased its policy interest rate from 2.75 % to 3.00 % on August 27. This is the second consecutive adjustment following the increase on July 16, and was prompted by domestic growth exceeding expectations while inflationary pressures and financial stability risks remained significant.
The primary rationale for the rate hike was inflation expectations. Consumer price inflation was projected at 2.7 % this year and 2.3 % next year; whereas core inflation is expected to stay around 2.5 %, so there remains a risk of exceeding the target.
Growth prospects also influenced the decision. In its August economic outlook, the Bank of Korea forecast growth of 3.3 % this year and 2.9 % next year, with exports and investment gains leading to improvements in income levels and consumption recovery. Accordingly, raising rates is intended to raise borrowing costs, curb spending and investment, and lower expected inflation.
This policy move also has implications for financial stability. Even as domestic bond yields and currency volatility persist, it may reduce the likelihood of risk‑asset price swings. The Bank of Korea will continue monitoring data and, together with inflation, growth, and financial conditions, set its policy direction accordingly.
