• Maize deliveries reached 312,717 tonnes between 1 April and 24 July 2026, up 106% on 152,047 tonnes a year earlier
• The volume is 11.6% of the 2,685,021 tonne crop, so 88% remains outside formal channels. It already exceeds the 227,338 tonne strategic grain reserve on its own
• GMB is paying US$364.75 a tonne for maize, above the ZMX spot price of US$348.60 and the US$337 import parity, which is what pulled the grain in. The board paid US$20 million and ZiG 230 million since 1 April.
• The 600,000 tonne reserve target has to be met from this harvest, because the next crop is the drought crop

Harare- Zimbabwe’s formal maize deliveries have reached 312,717 tonnes between 1 April and 24 July 2026, up 106% on the 152,047 tonnes marketed in the same window a year earlier, according to the latest Agricultural Marketing Authority data. National maize production rose 49.2% over the same period, from 1.8 million tonnes to 2,685,021 tonnes, so deliveries grew roughly twice as fast as output.

Hence, farmers did not mainly grow more maize, they even sent a far larger share of what they grew through the formal market.

The gap between a 106% delivery rise and a 49.2% production rise is the whole point, and it has a price behind it. GMB set a floor producer price of US$364.75 a tonne for maize and traditional grains for the 2025/26 season, paid partly in foreign currency and partly in ZiG at the interbank rate. That floor sits above the Zimbabwe Mercantile Exchange spot price, which eased to US$348.60 a tonne in June, and above the regional import parity estimate of US$337.

When the state buyer pays more than the open market and more than imported grain would cost, grain that would otherwise stay on the farm or move informally comes to the depot.

The board has backed the price with payment behaviour, which is the second half of why the grain moved. GMB reports paying US$20 million and ZiG 230 million for grain delivered since the season opened on 1 April, and settled older obligations of US$5.2 million and ZiG 62 million. Growers who were burned by slow payment in past seasons are the ones deciding whether to deliver now. With GMB having cleared all outstanding debts to farmers in both USD and ZiG, and with new deliveries settled promptly, that confidence is being rebuilt.

The scale of what has not been marketed is where the reserve managers should look. At 312,717 tonnes, formal deliveries are 11.6% of the 2,685,021 tonne crop, so close to 2.37 million tonnes, 88% of the harvest, is held on farm for consumption and seed, traded informally, or waiting for a better price later in the season. A large retained share is normal for a communal-dominated crop, and the marketing season still runs for months. The figure nonetheless measures how thin the formal pipeline is against the size of the harvest, which matters more this year than in a normal one.

What makes it matter is the reserve target set against a coming drought. Cabinet has committed to a strategic grain reserve of 600,000 tonnes by mid-2027, against a reserve that stood at 227,338 tonnes across all grains at the July post-Cabinet briefing, and it did so explicitly against an intensifying El Niño. The grain to fill that reserve has to be bought from the harvest now being marketed, because the next harvest, planted from October into the drought, is the one that fails. Maize deliveries at double last year’s rate are the single best input to that build, and the 312,717 tonnes marketed through all channels already exceeds the current whole-grain reserve.

The demand side is tightening at the same time, which competes with the reserve for the grain. The stockfeed sector is expanding as broiler, egg, beef and dairy output grows, and millers and stockfeed manufacturers are competing with GMB for limited supply. On the Mercantile Exchange, buyer demand of 7,000 tonnes met seller offers of 6,510 tonnes in early June, a market close to balance despite the harvest coming in. A new rule requiring millers and processors to source at least 40% of their supply locally from April 2026, under Statutory Instrument 87 of 2025, adds a further formal claim on the crop. The reserve is bidding against a feed industry and a milling mandate for the same tonnes.

The regional context explains why the grain stays home and the price holds. Zimbabwe trades maize at a premium to the rest of the continent, with South Africa the cheapest at around US$194 a tonne and other regional markets between US$217 and US$328, against a Zimbabwean spot near US$348. That premium keeps domestic grain from being drawn across the border and supports the local price, and it is the mirror image of the drought risk, since the same premium means imported replacement grain would be expensive if the reserve is not filled from local supply first.

The USDA expects Zimbabwean maize imports to fall 25% on the stricter import controls and the local-sourcing rule, which raises the stakes on domestic procurement.

The read on maize is a genuinely strong marketing season arriving exactly when it is needed. The doubling of deliveries is real, it is priced and not forced, and it lands in the one year when the reserve has to be built ahead of a drought the forecasters have all-round confirmed.

The open question is whether the formal pipeline, at 11.6% of the crop so far, deepens fast enough to carry the reserve to 600,000 tonnes as a growing feed sector and a 40% milling mandate compete for the same grain. The price is right and the payment is improving. The volume through the depot over the next three months is what decides it.

In the next 30 to 90 days the key variables to watch are the delivery run-rate against the 600,000-tonne reserve target (currently 312,717 tonnes through all channels, since the reserve must still be built from this harvest), the GMB floor of US$364.75 against the ZMX spot of US$348.60 (the premium that pulls grain to the depot, any narrowing of which would slow deliveries), and compliance with the 40% local-sourcing mandate under Statutory Instrument 87 of 2025, which will determine how hard millers and processors compete with the reserve for the same crop.
