About Core Inflation Rate YoY — Indonesia
DEFINITION
The Core Inflation Rate YoY is a key financial indicator that measures the change in prices of goods and services over a 12-month period, excluding volatile items such as food and energy. It provides a more accurate and stable representation of overall inflation trends, allowing businesses and policymakers to make informed decisions about economic policies and investments. This indicator is widely used by financial analysts and investors to assess the health of an economy and predict future inflation levels.
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 2.59 %, consensus 2.52 %. Prior reading (Apr 2026): 2.44 %. Before that (Mar 2026): 2.52 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a similar reading versus the latest print, with the 3-month outlook reinforcing that direction. Both horizons are aligned bullish for this indicator, suggesting a consistent trend signal. Trend-driven dynamics are the primary headwind in the current projection. This indicator correlates most strongly with Nikkei 225 (Bearish Nikkei 225, r=-0.69) — a useful reference for index-focused traders.
