About IPCA mid-month CPI YoY — Brazil
DEFINITION
IPCA mid-month CPI YoY is a key financial indicator that measures the year-over-year change in the Consumer Price Index (CPI) for mid-month in Brazil. This indicator is used to track inflation and price stability in the country, providing valuable insights for investors, businesses, and policymakers. A higher IPCA mid-month CPI YoY indicates an increase in the overall cost of goods and services, while a lower reading suggests a decrease in prices. This indicator is closely monitored by the Brazilian government and financial institutions to make informed decisions related to monetary policy and economic planning.
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 (Sep 2026): actual 4.47 %, consensus 4.3 %. Prior reading (Aug 2026): 4.24 %. Before that (Jul 2026): 4.52 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a similar reading versus the latest print, with the 3-month outlook diverging from that direction. The 1-month and 3-month horizons disagree, suggesting a mixed signal. Trend-driven dynamics are the primary headwind in the current projection. This indicator correlates most strongly with EUR/USD (Bullish EUR, r=0.42) — a useful reference for forex-focused traders.
