About CPI YoY — South Korea
DEFINITION
South Korea's CPI YoY rose to 3.100000% in June, beating the 3.000000% estimate and up from May's 2.600000%. This acceleration signals a faster inflation pace compared to the previous month. Market focus will remain on the Bank of Korea's response amid rising price pressures. Updated 6/2/26
WHY THIS INDICATOR MATTERS
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (May 2026): actual 3.1 %, consensus 3 %. Prior reading (Apr 2026): 2.6 %. Before that (Mar 2026): 2.2 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a lower reading versus the latest print. Current dynamics are the primary headwind in the projection. This indicator correlates most strongly with USD/KRW (Bullish KRW, r=-0.50) — a useful reference for forex-focused traders.
