South Korea’s consumer price index (CPI) rose 0.5% month-over-month in May 2026, matching the 0.5% increase recorded in April 2026, according to data updated on 1 June 2026. The back‑to‑back identical readings indicate that the pace of monthly price gains has stabilized rather than accelerating or cooling further.
On a month-over-month basis, the “actual” figure for May reflects price changes compared with April, while the “previous” figure shows April’s change versus March. With both periods coming in at 0.5%, the data suggest that short-term inflation pressures have remained consistent across the last two months. Investors and policymakers will now be watching upcoming releases closely to see whether this plateau in monthly CPI marks a new trend or a temporary pause in price dynamics.
