La Réunion's inflation rate in September 2026

The Insee estimates the annual inflation at La Réunion in September 2026 at 1.9%, compared to 3.1% for the entire France. Energy prices increased by 20.3%, while food prices remained relatively contained.

Inflation comparison with previous month

Inflation reached 1.9% on an annual basis at La Réunion in September 2026, compared to 1.4% in August. According to Insee, in its report published on October 28, the acceleration is mainly linked to energy. However, on a monthly basis, the general price index decreased by 0.2%.

Energy price impact

Energy prices increased by 20.3% between September 2025 and September 2026 on the island, after 15.1% in August. Petroleum products increased by 28.6% on an annual basis and by 5.9% in a month. Insee measures, between August and September, an increase of 13 cents in diesel and 5 cents in super fuel.

Energy's role in inflation

Energy represents 6.6% of the weight of expenditures of Reunionese households in the index. Its increase explains a large part of the annual inflation: excluding energy, prices only rise by 0.6% on an annual basis, compared to 1.6% for the entire country.

Food prices at La Réunion

Food prices decreased by 0.4% in September at La Réunion, with a decline of 2% in fresh products. Over twelve months, food only increased by 0.4%, compared to 1.4% nationally. Fresh products from La Réunion show an annual increase of 0.8%, far from the 9.5% recorded nationally.

Other product and service price trends

Manufactured products decreased by 1.3% on the month and by 0.8% on an annual basis. The monthly decrease concerns particularly clothing and shoes (-4.9%), in a context of sales. Services decreased by 0.3% in September, but remain 1.4% more expensive than a year ago. Rents, water and household waste collection increased by 1.1% on an annual basis.

Understanding the two inflation measures

The two measures describe distinct phenomena. The 0.2% decrease between August and September corresponds to a monthly variation of the index, while the 1.9% measures the difference with September 2025. This latter has deepened since July, when the annual inflation was limited to 0.7%.

National comparison and energy differences

The national comparison is based on the final results of September published by Insee on October 15. It reveals another significant gap: petroleum products increase by 36.2% on an annual basis throughout France, compared to 28.6% at La Réunion. For households on the island, the composition of expenditures and local devices therefore explain different price trajectories according to the items, despite a common energy pressure.
