India’s retail inflation likely rose to 20-month high of 4.9% in August: Mint poll
Retail inflation, measured by the Consumer Price Index (CPI), is estimated to have climbed to around a 20-month high for August 2026, with pre-release polls of economists pointing to a figure in the 4.8–4.9% range.
This would mark the third consecutive month that CPI inflation has stayed above the Reserve Bank of India's (RBI) medium-term target of 4%, a threshold first breached in June 2026.
Rising food prices are cited as the principal driver, with food and beverages inflation expected to climb from around 5.24% in July toward roughly 6% in August; continuing supply-side risks linked to the West Asia conflict are flagged as an additional pressure on fuel and commodity costs.
The Ministry of Statistics and Programme Implementation (MoSPI) is scheduled to release the official CPI data for August, which will feed into the Monetary Policy Committee's (MPC) assessment ahead of its next review.
Consumer Price Index (CPI) and Its Methodology
CPI measures the average change in prices paid by consumers for a fixed basket of goods and services over time, and is India's principal inflation gauge for monetary policy. It is compiled and released monthly by the National Statistical Office (NSO) under MoSPI.
Key Details
- The CPI (Combined, rural + urban) series currently in use has base year 2012=100; a revised series with base year 2024=100 has been scheduled for rollout, moving away from the 2012 base used since 2014-15.
- The CPI basket assigns the largest weight to food and beverages (roughly 46% of the combined index), followed by housing, fuel and light, and miscellaneous items.
- CPI differs from the Wholesale Price Index (WPI), compiled by the Office of the Economic Adviser (Department for Promotion of Industry and Internal Trade) — WPI tracks prices at the wholesale/producer level and excludes services, while CPI captures retail, consumer-facing prices and is the RBI's statutory inflation-targeting anchor.
- CPI data is typically released around the 12th of the following month.
The reported rise toward 4.9% is a CPI (not WPI) reading, and its composition — driven mainly by food inflation — illustrates why CPI's heavy food weight makes it sensitive to monsoon and geopolitical supply shocks, unlike WPI.
RBI's Flexible Inflation Targeting Framework and the MPC
India adopted a statutory flexible inflation targeting (FIT) framework via the RBI Act, 1934 (as amended in 2016), under which the Central Government notifies an inflation target in consultation with the RBI, and a six-member Monetary Policy Committee (MPC) sets the policy repo rate to achieve it.
Key Details
- The inflation target is 4% CPI inflation, with a tolerance band of +/- 2% (i.e., 2% to 6%), first notified in August 2016 for the period 2016–2021, and retained for a further five years to March 2026.
- The MPC comprises three RBI officials (including the Governor as Chairperson) and three external members appointed by the Government; rate decisions are by majority vote.
- If CPI inflation remains outside the 2–6% band for three consecutive quarters, the RBI is statutorily required to submit a report to the Government explaining the failure, its causes, and remedial measures.
- Persistent above-target CPI readings (as flagged in this case) typically weigh against further repo rate cuts and can prompt a more hawkish policy stance at the next MPC review.
With CPI inflation reported near 4.9%, still within the RBI's 2–6% tolerance band but above the 4% target, the MPC faces continued pressure to balance growth support against the risk of inflation drifting further from target, especially with food and geopolitical-driven fuel risks in play.
- CPI inflation (August 2026, estimated/poll-based): approximately 4.8–4.9%, a roughly 20-month high.
- RBI's medium-term CPI target: 4%, with a tolerance band of 2–6%, in force since August 2016 (renewed through March 2026).
- CPI target first breached on the upside in the current cycle: June 2026.
- Food and beverages inflation: around 5.24% in July 2026, expected near 6% in August 2026.
- CPI base year (current series): 2012=100; MoSPI/NSO is the compiling authority.
