FUEL prices across the country are in slight decreases, with petrol dropping by 36/- per litre and diesel by 23/- per litre starting yesterday. Dr James Andilile, the Energy and Water Utilities Regulatory Authority (EWURA) director general, said in a statement yesterday that price adjustments resulted from changes in the world market.

Globally the price of petrol decreased by 0.2 percent, diesel by 5.5 percent and kerosene by 3.5 percent compared to August 2025 prices, while average foreign exchange conversion cost for September declined by 3.96 percent, he said.

This also contributed to the downward adjustment of local pump prices as the exchange rate plays a critical role in determining the final consumer prices given that fuel imports are transacted in foreign currencies, he said.

Monthly new rates relate to cost particulars of consignments received at the ports of Dar es Salaam, Tanga and Mtwara, where despite overall decrease, the cost of importing fuel through Dar es Salaam port rose sharply during the period under review.

It climbed by 20.73 percent for petrol, 7.75 percent for diesel and 2.62 percent for kerosene, while at the Tanga port import costs fell significantly, by 12.66 percent for both petrol and diesel. Mtwara port imports showed no notable changes in costs, the statement indicated.

These adjustments reflect EWURA’s mandate to align local prices with prevailing global trends and associated costs while safeguarding consumer interest, it affirmed, reassuring the public that despite fluctuations in the world market, the regulatory agency was closely monitoring the situation to oversee stable and fair pricing.

EWURA reminded wholesale and retail fuel traders to strictly adhere to approved prices, as selling fuel above set out rates invites stern legal action. Compliance is mandatory to protect consumers from exploitation, the statement intoned.

Fuel prices are reviewed monthly to take into account changes in global oil prices, freight charges, insurance costs, port handling charges and exchange rate movements.

The September review is expected to offer slight relief to consumers, particularly transport operators, with future adjustments likely to depend on ongoing volatility in the global oil market, analysts noted.
