The Bank of Korea (BoK) maintained its policy rate at 2.50% for the eighth consecutive meeting, a move that was widely anticipated by the market. However, the central bank adopted a notably hawkish tone, with Governor Shin Hyun Song stating that the Board 'judged necessary to raise the Base Rate at an appropriate time' [1]. This sentiment was reinforced by the first hawkish dissent of the current cycle, as two of the seven Board members, Chang Yongsung and Ryoo Sangdai, voted in favor of a 25 basis point hike [1].
Following the BoK's announcement, the USD/KRW exchange rate eased back toward 1500 after briefly surpassing 1510. The Kospi index experienced significant volatility, plunging as much as 5% before paring losses to around 1% [1]. Brown Brothers Harriman’s Elias Haddad highlighted that the South Korean Won (KRW) remains significantly undervalued on a real effective basis, currently over -11% below its trend—the largest undervaluation since 2009. Haddad expects this mispricing to persist until the ongoing energy shock subsides [1].
In addition to its policy stance, the BoK revised its economic forecasts upward. The central bank raised its 2026 real GDP growth projection by 0.6 percentage points to 2.6%. It also increased its inflation outlook, with headline CPI forecasted up by 0.5 percentage points to 2.7% and core CPI up by 0.3 percentage points to 2.4% [1].
The combination of a hawkish policy signal, upwardly revised economic forecasts, and persistent undervaluation of the KRW suggests that the BoK is preparing the market for potential tightening, though the timing remains dependent on external factors such as the energy shock [1].
CONCLUSION
The Bank of Korea's hawkish hold and upward revisions to growth and inflation forecasts signal a potential rate hike ahead, contributing to market volatility and a partial recovery in the Kospi. The South Korean Won remains deeply undervalued, with normalization unlikely until energy market pressures ease. Investors should monitor BoK communications and global energy trends for further direction.
