French overseas territories displayed varied inflation patterns in August 2025, with Guadeloupe maintaining price stability while La Réunion experienced a notable monthly decline. According to data from France's national statistics institute Insee, consumer prices in Guadeloupe remained unchanged from July, following a slight 0.3% increase the previous month. Meanwhile, La Réunion saw prices decrease by 0.7% in August after a 0.6% rise in July, highlighting contrasting economic dynamics across France's overseas departments.

The energy sector emerged as a significant deflationary force across all territories. Guadeloupe recorded a 1.7% monthly drop in energy prices, contributing to an annual decline of 7.5%, while La Réunion experienced an even steeper annual decrease of 11.1%. This trend was largely driven by falling petroleum product prices, which declined by 1.0% in August across both territories. The energy price reductions helped temper overall inflation rates, particularly in Guadeloupe where the annual inflation rate stood at 0.8%, slightly below mainland France's 0.9%.

Food prices showed divergent patterns, with La Réunion experiencing a sharp 1.5% monthly decline primarily due to a 10.5% drop in fresh product prices as markets normalized following spring cyclone disruptions. In contrast, Guadeloupe maintained stable food prices monthly, though annual food inflation reached 1.5%, closely aligning with the national average of 1.6%. The fresh produce sector in La Réunion returned to levels接近 those seen in February 2025, indicating a recovery from weather-related supply chain disruptions earlier in the year.

Services continued to outpace national inflation trends, with both territories recording identical 3.1% annual increases. Transportation services showed particularly volatile movements, with La Réunion experiencing a 22.6% drop in air transport prices in August following a 24.6% surge in July due to seasonal tourism patterns. Manufactured goods prices remained generally stable or slightly negative annually across both territories, while tobacco prices showed significant increases, reaching 4.0% annually in Guadeloupe. These sectoral variations underscore the complex economic landscape facing France's overseas departments as they balance local market conditions with national economic trends.
