NEW DELHI:July’s retail inflation figure arrives on Wednesday, and forecasts cluster around 4.5 per cent. Almost every household reading that will feel it understates their month. Both can be true, and the reason is worth understanding once, properly.
The consumer price index is not a measure of how expensive life is. It is a measure of how much the price of one fixed, weighted shopping basket has changed since the same month a year earlier. Two design choices in that sentence do most of the work. The first is fixed: the basket’s contents and weights are held constant, so the index tracks price movement rather than changes in what people buy. The second is a year earlier: the comparison is with last July, not last month, which means a price that rose steeply twelve months ago and has merely stayed high since will show up as no inflation at all. It is still hurting the household. It has simply stopped being news to the index.
Where the disagreement lives: the index averages a basket. A household buys the items in it at very different frequencies, and remembers the ones it buys most often.
The index is an average of a basket. Nobody buys the average. That gap is not an error in the statistics — it is the point of them.
At a Glance
• Data due: July 2026 retail inflation, Wednesday, August 12
• Forecast: about 4.5 per cent, with risks to the upside (Bank of Baroda)
• Core inflation: expected near 4 to 4.1 per cent
• Pressure points named: onions, edible oils, rice, pulses
• Bank of Baroda essential commodities index: up 4.1 per cent year on year in July — the sharpest in that series
• RBI projection: 5 per cent CPI inflation for FY27, trimmed from 5.1
• Repo rate: unchanged at 5.25 per cent since August 5
• What CPI measures: price change in a fixed basket, against the same month a year earlier
The second reason for the gap is frequency. A household buys vegetables several times a week, cooking oil monthly, a school uniform twice a year and a refrigerator once a decade. Its felt inflation is dominated by the items it touches most often — and food is exactly where the pressure sits this month, with onions, edible oils, rice and pulses named as the main contributors. That is why a separate essential-commodities gauge compiled by Bank of Baroda rose 4.1 per cent year on year in July, the sharpest reading in that series, while the headline forecast sits near 4.5 per cent and core inflation, which strips out food and fuel, is expected around 4 to 4.1 per cent. Three different numbers, all defensible, all measuring something different.
Knowing which number answers which question is the useful part. If you want to know what your kitchen will cost next month, watch food inflation and the mandi prices behind it. If you want to know whether the price pressure is spreading into the wider economy — rents, services, fees — watch core. If you want to know what the Reserve Bank is likely to do, watch headline inflation against its own projection, currently 5 per cent for the financial year, with the repo rate held at 5.25 per cent since August 5. The Monetary Policy Committee said it wanted greater clarity on the inflation outlook before acting, and noted little sign so far that price pressure has generalised beyond food and fuel. Wednesday’s print is one of the readings it will use to decide whether that judgement still holds. Read it as a diagnostic, not a verdict on your own month — and read the food line first.
