Ghanaian Oil Marketing Companies (OMCs) have started increasing fuel prices at the pumps. Star Oil, a major market player, adjusted its prices on August 1, 2026, setting petrol at GHS 14.53 per litre and diesel at GHS 18.77 per litre.
This price hike follows industry projections and aligns with the bi-weekly fuel price review mechanism. This system operates under Ghana's petroleum price deregulation policy. The increases reflect a sharp rise in international crude oil prices and a depreciation of the Ghana cedi against the US dollar.
These adjustments are a regular feature of Ghana's deregulated petroleum market. The policy allows OMCs to set their prices based on market forces. This approach aims to ensure a consistent supply of fuel but often leads to price volatility for consumers. The current increases will likely impact transport costs and the broader economy, which relies heavily on fuel.
Philip Tieku, Chief Executive of Star Oil, explained the reasons behind the price changes. In a Facebook post on July 24, 2026, he stated that world market prices for gasoline have increased by nearly 20%. Diesel prices have also risen by approximately 25% during the current pricing window. The Ghana cedi has also depreciated against the US dollar in the same period, further increasing import costs.
The immediate implication of these price hikes is increased operational costs for businesses and individuals. Transport operators, particularly the Ghana Private Road Transport Union, may renew their calls for fare increases. This could lead to higher costs for commuters and goods, potentially fueling inflation. Decision-makers will closely monitor the impact on consumer spending and economic stability.
Many OMCs are increasing prices even before August 1, 2026. This is because most players purchase petroleum products daily on a cash-and-carry basis. Every new stock purchase is priced using prevailing international petroleum prices and the current exchange rate. Mr. Tieku noted this practice helps prevent arbitrage opportunities.
More OMCs are expected to review their prices on August 2, 2026, with others adjusting by August 3, 2026. Some have indicated they will work with industry price quotes. This could see petrol reach at least GHS 15.23 and diesel exceed GHS 18 per litre. Market analysts believe the increases may not be as steep for many consumers, as several OMCs have already raised prices in recent weeks.
The Chamber of Bulk Oil Distributors (COMAC) attributed the projected increase to a sharp rise in global crude oil prices. Average crude oil prices increased by 23.25% during the review period. Refined petroleum products also recorded substantial gains, with diesel posting the highest increase at 24.84%. Petrol increased by 12.58% and LPG by 12.24%.
Average crude oil prices climbed from US$71.90 to US$88.62 per barrel. COMAC linked this surge to heightened geopolitical tensions, specifically developments surrounding the US-Iran conflict. Uncertainty over the reopening of the Strait of Hormuz has sustained these risks, keeping Brent crude near US$88 per barrel. The cedi's depreciation also played a role.
For the August 1 pricing window, the exchange rate moved from GHS 11.4970 to GHS 11.6593 per US dollar. This represents a 1.41% depreciation, further increasing the cost of importing petroleum products. This currency weakness adds to the burden on OMCs and, ultimately, on Ghanaian consumers.
