Cocoa drops roughly 5%: surplus pressure, Ivory Coast and the arrivals data that can mislead

Cocoa ended the week under renewed pressure. In a Reuters snapshot at 13:26 GMT on September 18, London cocoa was down 4.3% at £4,227 a ton, while New York cocoa fell 4.9% to $5,603 after touching an intraday low of $5,530. It was heading for a third consecutive weekly decline.

For CFD traders, the useful reading is not simply ‘more supply equals lower cocoa.’ The market is separating expected surplus, weaker demand, Ivory Coast crop timing and the quality of early arrival data.

The drivers to separate

The statistical trap in early arrivals

The 26,000-ton figure can look weak in isolation. But Reuters had already reported on August 26 that the 2026/27 main season would formally start on September 1, with weekly arrivals expected below 15,000 tons in September and below 25,000 in October before accelerating from late October and November.

Low early arrivals therefore do not automatically prove physical scarcity. They can reflect the timing of a season whose official calendar starts earlier, a delayed crop and a later concentration of volumes.

Why futures are still falling

Reuters says dealers are focusing on an expected seasonal surplus and on concerns that previously high cocoa prices damaged third-quarter demand. The market also expects port supplies to build as the new marketing season progresses.

That is why cocoa can fall even while the first arrival numbers remain modest: futures price expectations about what may reach the market in coming weeks, not only beans already sitting at port.

Traceability adds operational noise

From September 1, Ivory Coast requires an electronic producer card as part of a new national traceability system ahead of European anti-deforestation rules. Reuters documented early difficulties for cooperatives and buyers, including uneven access to terminals and unfamiliar digital procedures.

That does not mean traceability caused the sell-off. It means early delivery data may contain more logistical noise than usual and should not be converted automatically into a supply thesis.

The counterpoint: future supply still carries risk

The story is not one-way bearish. Reuters reported the main crop is delayed by difficult weather, insufficient farm maintenance and an unusually strong mid-crop. August estimates pointed to about 900,000 tons of arrivals from October through December 2026, versus 1.1 million tons in the same 2025 period.

So the market is currently pricing better near-term availability and a surplus expectation while remaining exposed to crop timing, bean quality and West African weather.

What cocoa CFD traders should watch

Three checks matter more than a forecast: the pace of port arrivals after September, grind/demand evidence after months of high prices, and weather in Ivory Coast and Ghana. Faster arrivals with weak demand would reinforce the surplus view. Persistent delays would force the market to reassess effective availability.

This morning we examined a different commodity problem in copper: Chinese physical demand versus COT positioning. Cocoa is different: the challenge is separating logistics, calendar effects and actual supply.

The practical lesson is simple: one arrivals number is not enough for a thesis. In cocoa, the calendar and traceability rollout matter almost as much as the headline tonnage.
