What this value means
June 2026 index 119.99 (2020=100), +0.1% m/m, +3.2% y/y — the fastest since December 2023, second straight month above 3%. Core CPI (ex food & energy) +2.5% y/y; living-cost index +3.4%; petroleum products +24.7% y/y (largest since July 2022) on Middle East tensions and won weakness. Monthly index levels: May 119.92, Apr 119.37, Mar 118.80 (from official korea.kr briefing transcripts, loaded). Access quirks: the statistics office was renamed from 통계청 (Statistics Korea/KOSTAT) to 국가데이터처 under the 2025 government reorganisation — kostat.go.kr deep links now 301-redirect to mods.go.kr; a CPI rebasing to 2025=100 was announced 2026-07-07 (release list_no=445795), so index levels (not the published y/y rates) will be restated when the new base goes live.
