Wholesale Onion Prices Are Falling. Retail Prices Are Not Following Yet.
Wholesale onion prices turned down weeks ago. Retail prices have barely followed. That gap — between what the mandi has already priced in and what the shop counter still charges — is the live question in India's onion market this month, and it is a question about transmission, not about supply. Supply, on the government's own numbers, is improving from three directions at once.
Wholesale moved first, and it moved clearly
In Maharashtra, the state that sets the tone for this market, the weighted average mandi price fell by nearly 13 per cent in just over a fortnight — from around ₹4,030 per quintal on 16 September to about ₹3,475 per quintal on 3 October, according to the Consumer Affairs ministry. The all-India picture points the same way. The average mandi price has come down from a peak of approximately ₹3,600 per quintal in September to around ₹3,300 per quintal in October.
| Series | Earlier | Latest |
|---|---|---|
| Maharashtra weighted avg mandi price | ₹4,030/qtl (16 Sep) | ₹3,475/qtl (3 Oct) |
| All-India average mandi price | ~₹3,600/qtl (Sep peak) | ~₹3,300/qtl (Oct) |
| All-India average retail price | ₹26.65/kg (Oct 2025) | ₹52.99/kg (10 Oct 2026) |

Fresh arrivals are doing part of this work. Kharif onions have started arriving from Karnataka, Andhra Pradesh and Rajasthan, stored rabi stocks are still feeding the market alongside them, and the ministry expects arrivals to build further through the festive weeks. None of that is a forecast of abundance. It is a sequence: the wholesale market prices the arrivals it can see, and it has priced them down.
Retail is telling a different story
At the counter, the same month looks almost flat. The all-India average retail price stood at ₹52.99 per kg on 10 October — down just 0.2 per cent over the month, and still close to double the ₹26.65 per kg recorded a year earlier. Wholesale prices averaged ₹4,591 per quintal on the same government data, up 123.3 per cent from a year ago. A buyer reading only the retail series would conclude nothing has changed. A buyer reading only the mandi series would conclude the correction is done. Both readings are wrong, and the distance between them is where procurement mistakes get made.
The city detail shows the turn starting, unevenly. On 7 October the ministry counted 126 cities where retail prices had fallen by ₹1–21 per kg over two weeks. Nine days later the count had widened: 211 cities had reported declines of ₹1–13 per kg. Transmission is happening. It is happening city by city, at different speeds, which is exactly why a national average is the last place it shows up.
The buffer is the third supply channel, and it is a logistics operation
Between the stored crop and the fresh crop sits the government's buffer, and this season it is being moved like a freight problem, because it is one. By 7 October the government had disposed of more than 2.0 lakh quintals of buffer onions through 8 Kanda Express trains and 467 trucks across 123 cities, with additional rail rakes planned for high-consumption markets.
The Northeast run shows what that means at the margin. A consignment of approximately 440 metric tonnes was expected to reach Agartala by 18 October, covering seven of Tripura's eight districts. Before it, two Kanda Express consignments of 840 and 452 tonnes, plus 44 truck consignments totalling 1,513.46 tonnes, had already supplied Assam, Tripura and Nagaland. The effect is measurable where it lands: Assam's average retail price, at ₹54.30 per kg, now sits just ₹1.23 above the all-India average — two years ago the gap was ₹7.83. Buffer stock does not set the national price. Moved to the right deficit market, it closes the regional premium, and that is a different, more achievable job.
The arrivals calendar argues against paying the old price
The forward picture rests on acreage and timing, both stated plainly in the ministry's update. All-India kharif onion acreage is estimated at around 5 per cent higher than last year's level, crop conditions are reported favourable in the main producing regions, and the IMD rainfall outlook carries no forecast of excessive rains in the key kharif onion regions in the coming weeks — the condition that matters for harvesting, drying and movement.
Traders are reading the calendar in stages. Supplies from Karnataka, Telangana and Andhra Pradesh are expected to run to the end of November, Maharashtra and Madhya Pradesh hold old-crop stocks the trade judges sufficient until the third week of November, and Maharashtra's early kharif crop should start arriving in small quantities by the end of October, with Rajasthan's Alwar supplies reducing north India's dependence on Maharashtra in the meantime. That is a trader assessment reported in the press, not an official estimate. It is still the right shape for planning: supply arrives in waves, by region, over six weeks — not in one national step.
What to do while the two prices disagree
For processors, dehydrators, exporters and institutional buyers, the working rule this month is to price off the mandi and the arrivals calendar, not off the retail counter. Retail is a lagging indicator in a falling wholesale market; contracts indexed to it will overpay through November. For lenders and insurers with exposure to onion storage, the same lag cuts the other way: stock bought at September prices is being carried into a market whose wholesale line has already fallen an eighth in Maharashtra, and its realisable value should be marked on the mandi series, with the buffer-release calendar treated as a standing source of competing supply in deficit cities.
And for anyone building a price view, the discipline is to keep the three channels separate — stored crop, fresh arrivals, buffer movement — because each moves on its own timetable and each shows up in a different series first.
