NEW DELHI, October 16 — The Office of the Economic Adviser, Department for Promotion of Industry and Internal Trade (DPIIT), on Friday released the official Wholesale Price Index (WPI) data for September 2026, revealing that wholesale inflation moderated to 1.84 percent year-on-year.
The downward trajectory in wholesale price pressures was anchored by cooling retail-mandi arrivals across primary food articles—notably potatoes, onions, and seasonal pulses—alongside declining international energy inputs. The fuel and power sub-index registered deflationary prints at negative 2.1 percent, while manufactured products maintained modest stability at 1.15 percent.
Macroeconomists noted that subdued upstream wholesale inflation provides a vital disinflationary transmission pipeline into headline Consumer Price Index (CPI) numbers, expanding monetary leeway for the RBI's Monetary Policy Committee (MPC) to sustain accommodative liquidity conditions heading into the festive cycle.
The structural distinctions between the Wholesale Price Index (WPI, base year 2011-12, tracked by DPIIT without services component) and the Consumer Price Index (CPI, base year 2012, released by NSO), the Urjit Patel Committee recommendations anchoring inflation targeting at 4% ($\pm 2\%$), and headline versus core inflation dynamics are staple concepts in UPSC Civil Services (GS-III: Indian Economy) and RBI Grade B examinations.
