Applied Derivatives reported white maize at R4,302/t and yellow maize at R4,168/t on 16 October, with modest gains in both December contracts.
South Africa’s December maize futures ended the week to 16 October slightly higher, according to Applied Derivatives’ market note, providing a firmer reference point as attention turns to the next crop.
The broker put December white maize at R4,302 a tonne, up R25 from R4,277 on 12 October. December yellow maize moved from R4,156 to R4,168 a tonne, an increase of R12.
Calculated from those reported marks, the changes were about 0.58% for white maize and 0.29% for yellow maize. The white-maize premium over yellow maize widened from R121/t to R134/t over the same comparison.
These are dated December futures figures from the broker’s report. They are not Monday’s live prices, a spot-market quotation or a delivered price offered to an individual farmer.
Keep the contract and date together
The JSE describes its agricultural derivatives market as a platform for price discovery and price-risk management. White and yellow maize are among its grain futures and options products.
A futures price refers to a specified contract. That distinction matters when comparing a newspaper figure, a broker’s market screen and a buyer’s offer. A quotation for another delivery month is a different observation, even if both quotations refer to maize on the same trading day.
White and yellow maize also need to be tracked separately. In the reported December comparison, both contracts rose, but they did not rise by the same amount. Describing the week simply as a single maize-price increase would conceal that difference.
The percentage calculations are useful for putting the rand movements in proportion. They describe the change between the two quoted dates; they do not measure a producer’s return or establish the direction of the next session.
A market reference is one part of a transaction
The exchange’s account of its commodities market also identifies physical delivery and silo receipts as features of agricultural trading. The futures market therefore connects price discovery with a formal delivery system, although a quoted contract price is not itself a complete farm sale agreement.
For an actual transaction, the commodity, delivery arrangement and contract terms still matter. An isolated market number cannot establish the net amount a particular producer will receive, nor the total cost a particular buyer will incur.
The JSE distinguishes live or intraday data from end-of-day and historical data in its market-data offering. This report uses a dated broker summary and does not present the figures as an independently downloaded exchange settlement file.
What the weekly move establishes
The narrow conclusion is that the two reported December maize marks were firmer at the end of the stated comparison. The available figures do not, by themselves, explain how much of that move came from weather expectations, currency changes or trading activity.
The next useful comparison will be the same contracts on a later, clearly identified date. For farmers and grain users following planting-season markets, keeping that consistent reference is more informative than comparing numbers drawn from different months or different kinds of quotation.
