The Bank of Korea’s August 27 monetary policy decision occurs against a 2.75% policy rate set by the July 16 hike—the first tightening since 2023—driven by headline CPI at 3.2%, well above the 2% target, alongside elevated oil prices, a still-weak won, and rapid household credit and property price growth. Strong semiconductor export momentum tied to AI demand has eased growth concerns and supported a 2.6% 2026 GDP projection, while July board minutes and comments from outgoing and incoming deputy governors highlighted preemptive tightening risks. These elements underpin the 70.5% market-implied probability of a further 25 basis point hike to 3.00%, versus 29% odds of no change, as traders weigh inflation persistence against data-dependent caution on post-hike transmission effects ahead of the meeting.

This market may resolve as soon as the statement or release of the Bank of Korea's Monetary Policy Board resulting from its August 2026 meeting with relevant data is issued.
If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound.
If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of "Increase" or "Decrease" will include policy rate increases or decreases of any size.
