How India's monsoon shaped this year's food inflation

Every monsoon tells a price story. This year’s version began with a June that arrived ten days late over the grain belt, and ended with an August that dumped a month’s rain on Maharashtra’s vegetable districts in a single week. Both showed up, almost on schedule, in the consumer price index.

Food inflation is not one number but a bundle of very different markets. Cereals respond slowly, because stocks and procurement smooth the shock. Vegetables respond within weeks, because tomatoes and onions cannot be warehoused through a flood.

Where the pressure came from

Decompose June’s reading and the pattern is stark: vegetables alone contributed nearly half of the food inflation print, more than cereals, pulses and milk combined. That is the signature of a weather shock, not a demand surge.

When inflation is made of onions, interest rates are a blunt instrument. The relevant policy lever is cold storage, not the repo rate.

The practical takeaway for readers watching the RBI: a rain-driven spike tends to reverse as the winter crop arrives. What matters is whether households’ inflation expectations reset before it does.
