Bank of Korea Board Divided as August Rate Hike Odds Rise

The Bank of Korea's rate-setting board is divided over whether to deliver a second consecutive rate hike in August, according to minutes from its July meeting released on August 5. Four of the six Monetary Policy Board members, excluding Governor Shin Hyun-song, explicitly called for further tightening, while two held back from committing to a position, keeping alive uncertainty over what would be an unusual "back-to-back" move for the central bank.

The four hawkish members pointed to improving corporate investment and household income, along with rising import costs tied to the exchange rate, arguing that any slowdown in core inflation could take longer than expected. Their comments in the minutes ran notably longer on average than those of the two more cautious members, who said they wanted more time to assess real-economy and price data, with one also stressing the role fiscal policy should play in taming demand. The shorter, more guarded language attributed to the doves has been read by market watchers as a sign they are still wrestling with whether to back another hike rather than firmly opposing it.

The debate follows the BOK's decision in July to raise its base rate by a quarter point to 2.75%, a unanimous move that marked the bank's first increase in more than three years. At a briefing after that meeting, Shin described the coming policy sessions as "live meetings," language that left the door open to consecutive action rather than a pause.

Data published since then has strengthened the case for another hike. Second-quarter real gross domestic income jumped 15.6% from a year earlier, the fastest pace in 38 years, while core inflation in July climbed to 2.6%, its highest level in 31 months. Internal briefing materials from the BOK's executive wing separately flagged risks of price pressure and financial imbalances building up alongside stronger nominal growth, calling for tighter policy management.

Even so, the board's caution has not disappeared. Analysts note that the views of the deputy governor, who works closely with Shin in setting policy direction, are likely to carry outsized influence over the two undecided members when the board meets again. Should oil prices or the won weaken further in the coming weeks, easing some of the price pressure behind the case for tightening, the muted skepticism visible in the July minutes could resurface more forcefully, setting up a tighter contest at the August meeting.

For now, market participants say the outcome effectively rests with the two dovish board members, whose stance could tip the balance either toward a rare consecutive hike or a pause to assess how the economy absorbs July's increase.
