Petrol, diesel and LPG prices will rise marginally at the pumps from September 1, the Chamber of Petroleum Consumers (COPEC) has projected, with petrol seeing the steepest increase.

According to COPEC, petrol could climb to GH¢16.21 per litre, a 5% jump from the current GH¢15.43, with prices ranging between GH¢15.40 and GH¢17.02 within its usual margin of error.

Diesel is projected to edge up to GH¢17.61 per litre from GH¢17.17, while LPG is expected to rise to GH¢14.19 per kilogramme. COPEC's projections, released in a statement on August 30, 2026, and signed by Executive Secretary Duncan Amoah, cover the pricing window beginning Tuesday.

Notably, the increases come even as global crude oil prices dipped slightly and the cedi strengthened against the dollar. COPEC explained that petrol's international Free on Board (FOB) price surged by 10%, from $1,033.15 to $1,136.50 per metric tonne, a jump the chamber says outweighed the benefit of the stronger cedi.

COPEC's statement placed the blame squarely on external market forces rather than local currency performance, framing the petrol increase as driven almost entirely by the sharp rise in the product's global benchmark price. The chamber has appealed to government to extend its fuel subsidy support beyond August, and has separately called on Oil Marketing Companies to hold diesel prices steady to soften the blow on consumers.

The projected hikes come despite favourable macro conditions: the cedi appreciated roughly 2.39% against the dollar during the window, moving from about GH¢11.80 to GH¢11.5166, while average global crude prices dipped slightly from $89.41 to $89.30 per barrel. Diesel's FOB price stayed almost flat, but LPG's FOB price rose by about 2.64%. COPEC's ±5% margin means actual pump prices could ultimately land within a range around each projected figure once OMCs finalise their pricing for the new window.
