Reunion Island Drivers Brace for Sharp Fuel Cost Surge This September

FUEL PRICES SET TO CLIMB AGAIN IN SEPTEMBER FOR REUNION ISLAND DRIVERS

Motorists across Reunion Island face a difficult stretch ahead as fuel costs are poised to rise sharply in early September, ending the relative respite that August provided. The regional prefecture has already signaled a “significant increase” in pump prices for the coming month, a warning issued at the end of August before new tariffs take effect.

The announcement underscores a pattern that has gripped the island since April, when fuel prices began climbing in lockstep with global petroleum markets. August offered temporary relief, with unleaded petrol sitting at 1.78 euros per liter and diesel at 1.55 euros. That stability is unlikely to persist.

The root cause lies thousands of kilometers away. A conflict that erupted in the Middle East in late February continues to disrupt global energy supplies. The Strait of Hormuz, a critical chokepoint through which one-fifth of the world’s petroleum products once flowed, has been closed by Tehran since the war began. The conflict was triggered by strikes from the United States and Israel against Iran, prompting President Donald Trump to impose a naval blockade aimed at economic strangulation of the country.

Julien Baddour, a lecturer at the University of Reunion, explained the cascading effect on local pump prices. “This war, unfortunately, occurred in the zone that is most sensitive and most important from an energy and geopolitical perspective,” he said. “Consequently, the world’s principal producers and exporters are located in this region. Any prolongation of this conflict can only disrupt global crude oil supplies.”

The impact has been concrete and measurable. For nearly seven or eight months, very few vessels have transited the Strait of Hormuz, Baddour noted. Global supply has begun falling relative to worldwide demand, creating what he characterized as “total uncertainty” in market conditions.

Meanwhile, the prefecture emphasized that fuel prices depend entirely on international market rates and supply conditions, recalculated monthly by state services. The calculation involves multiple components: the average of quotations observed over 15 working days, supply costs, transportation and storage expenses, taxation, the euro-to-dollar exchange rate, and regulated margins that compensate importers and distributors. Fuels are exempt from value-added tax on Reunion Island, a distinction that sets the island apart from mainland France, where fuel pricing operates under different rules.

This pricing mechanism, established in 2014, is designed to guarantee a single price across the island that remains “faithful to market costs” with margins set “in complete transparency.” The prefecture said it wanted to explain these factors “so that everyone can better understand their evolution and be informed in advance, in a clear and transparent manner.” That commitment to transparency offers residents some clarity, even if it offers no shelter from the price itself.

Tensions around the Strait of Hormuz intensified again in July after a brief lull, directly contributing to the anticipated September surge. For ordinary residents filling their tanks on an island where there is no alternative to road transport, the question is not whether prices will rise, but by how much, and for how long the distant conflict will continue to reach into their daily lives.
