About WPI Inflation YoY — India
DEFINITION
WPI Inflation YoY, or Wholesale Price Index Inflation Year-over-Year, is a key economic indicator that measures the change in the average prices of goods sold in the wholesale market over a one-year period. It is used to track inflation trends and can provide insights into the overall health of the economy. A higher WPI Inflation YoY indicates an increase in prices, while a lower reading suggests a decrease. This indicator is closely monitored by policymakers, businesses, and investors to make informed decisions about monetary and fiscal policies, pricing strategies, and investment opportunities.
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. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Aug 2026): actual 9.92 %, consensus 9.89 %. Prior reading (Jul 2026): 9.78 %. Before that (Jun 2026): 9.87 %.
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 tailwind in the current projection. This indicator correlates most strongly with NIFTY 50 (Bullish NIFTY 50, r=0.54) — a useful reference for index-focused traders.
