Households in Mayotte face financial pressure

According to L'Institut national de la statistique et des études économiques (Insee), constrained spending has continued to weigh on households in Mayotte, despite a lower inflation rate than in the Hexagon. Although the price increase marked a pause, the relief remains relative.

Energy prices drive inflation in Mayotte

Energy remains the main driver of price increases in the island, with an annual growth of 14.1%. In September, energy prices increased by 3% on a monthly basis, after an increase of 0.9% in August. On an annual basis, the increase reached 14.1%, compared to 11.8% the previous month.

Petroleum products see sharp price increases

Petroleum products are particularly affected, with an annual increase of 20.9%. In September, the price of a liter of diesel increased by 14 cents, and that of super fuel by 6 cents. The price of a gas cylinder also increased by 50 cents, while that of electricity remained stable on the month. On an annual basis, electricity prices have nonetheless increased by 2.9%.

Energy costs impact household budgets

This evolution heavily weighs on a category that represents 8% of the consumption of Mahorais households, according to the institute. Furthermore, it fits into a trend also observed at the national level, where energy prices have increased by 21.3% on an annual basis. In the Hexagon, the increase in petroleum products has even reached 36.2%.

Some expenditure categories see price decreases

On the contrary, some expenditure categories experienced a decrease in September. This is particularly the case for services, whose prices decreased by 0.5%, after having increased by 0.8% in August. This decrease is mainly explained by the decrease in transport prices, which fell by 10.5% in a month, notably airplane tickets, whose prices decreased by 21.4% due to seasonal variations, according to Insee.

Food prices show slight declines

Food also contributed to slowing down the general increase in prices. In September, prices decreased by 0.6%, after a decrease of 0.2% the previous month. Prices of fresh products decreased by 0.4%, while those of other food products decreased by 0.7%.

Annual food price trends vary

On an annual basis, however, food prices remain almost unchanged in Mayotte, with a limited increase of 0.1%. Fresh products even show a decrease of 1.7%, while they increased by 9.5% in France. For other food products, the trend is slightly different, with an increase of 0.5% on an annual basis in the archipelago.

Manufactured products see mixed price changes

As for manufactured products, their prices also decreased in September, by 0.3%. This decrease is particularly linked to clothing and shoes, whose prices decreased by 1.2%. On an annual basis, the prices of these products decreased by 1.5%. On the contrary, other manufactured products increased by 0.7%, while health products increased by 1.2%. As for tobacco, prices did not change throughout the month of September, but they remain up by 2.6% on an annual basis. The same observation applies to rent, water, and household waste collection, whose prices remained stable on the month, despite an increase of 1.3% since September 2025.

Manufactured products show contrasting trends

Manufactured products follow a different trend. Their prices have slightly increased in Mayotte, by 0.2% on an annual basis, while they have decreased by 0.3% in the Hexagon. Energy remains, however, the main point of tension, even though its annual increase is less important in the island than at the national level.

Inflation has slowed in Mayotte

Another element to note, inflation has slowed down in Mayotte for several months. It reached 2% in July last, according to Insee figures. In the Hexagon, the trend is the opposite.
