South Korean Central Bank Sends Hawkish Signals; Two Dissenting Votes Stoke Expectations for July Rate Hike

The South Korean central bank announced on May 28th to keep the seven-day repurchase rate at 2.50% unchanged, extending the policy pause since last July, marking the eighth consecutive decision to stand pat. However, this meeting was far from calm.

The decision was not passed unanimously — out of seven committee members, two voted in favor of a rate hike. This rare internal divide, coupled with the central bank's substantial increase in economic forecasts, directly ignited market bets on a policy shift. The central bank raised its 2026 inflation expectation from 2.2% to 2.7% and its growth expectation from 2.0% to 2.6%, stating that "policy will be implemented to stabilize inflation at target levels," while emphasizing "the need to pay attention to drastic fluctuations in exchange rates."

The core logic for the central bank's attitude shift is the combination of higher-than-expected inflation and growth. On the inflation front, South Korea's consumer inflation rate for April rose to 2.6%, a 21-month high, with the closure of the Strait of Hormuz due to the Iran war driving up energy costs being the main force. On the growth front, exports jumped 48% year-on-year in April, with a revised increase of 50% for March, driven by surging semiconductor shipments, benefiting from the robust demand generated by the large-scale construction of AI infrastructure by global tech companies. The simultaneous strength in both directions means that the central bank's previous logic of "using easing to support growth" is no longer sustainable.

Market expectations for the rate hike path are rapidly converging. CHO Yong-gu, a fixed income strategist at Shinyoung Securities, said: "Inflation seems to have a bit more room to rise, and the likelihood of the Bank of Korea taking action in July is quite high. If there are two dissenting votes in favor of a rate hike, the market might quickly start pricing for a July hike."

Citigroup economist Jin-Wook Kim expects the Bank of Korea to raise rates once each in July and October 2026, and in January and April 2027, totaling four times. Bloomberg quoted economist Hyosung Kwon as saying that the substantial increase in growth and inflation forecasts means that "policy trade-offs have shifted from supporting growth to controlling inflation," and the Bank of Korea is paving the way for a tightening cycle.

There were two additional notable backgrounds to this meeting: the newly appointed governor Shin Hyun Song chaired his first monetary policy meeting since taking office; and new member Kim Jinill, a former Fed economist widely perceived as more hawkish than his predecessor, participated in the decision-making for the first time. The Bank of Korea's simultaneous release of the rate dot plot, together with the governor's press conference remarks, became key references for the market to interpret future policy paths.

The won reacted indifferently to the decision, falling about 0.3% against the dollar after the announcement, roughly in line with the intraday trend.
