Petrol Prices To Go Up By 9.63%, Diesel By 6.97% From September 16 – COMAC Projects

Petroleum prices are set to go up significantly from Wednesday, September 16, 2026.

The Chamber of Oil Marketing Companies (COMAC) is projecting a 9.63% increase in petrol prices and 6.97% increase in diesel prices at the start of the second pricing window for September.

Liquefied Petroleum Gas (LPG) is also expected to go up by 3.22%, according to COMAC's latest pricing outlook.

The Chamber attributes the projected increases to rising international crude oil and refined petroleum product prices.

Per COMAC's projections based on cash purchases, petrol could be sold at GH¢17.23 per litre, diesel at GH¢18.35 per litre, while LPG could sell at GH¢16.66 per kilogramme.

COMAC however says government’s GH¢2 per litre intervention on diesel will remain in place to reduce the impact on consumers.

The forecast comes as the National Petroleum Authority (NPA) has increased the price floors for all three products for the second window. Petrol's floor price has been set at GH¢16 per litre, diesel at GH¢16.77 per litre and LPG at GH¢10.97 per litre.

This represents an increase from the first window in September. Petrol's floor has moved up by GH¢1.47 from GH¢14.53, diesel by GH¢1.17 from GH¢15.60, and LPG by GH¢0.12 from GH¢10.85.

The NPA floors are not the final retail prices. Under the Petroleum Product Pricing Guidelines, the floors do not include premiums by International Oil Trading Companies, operating margins of Bulk Import, Distribution and Export Companies (BIDECs) and margins for marketers and dealers.

The expected hikes are driven by a sharp rise in crude oil on the international market. Average crude oil price went up by 12.29% to US$104.01 per barrel for the September 16 window – crossing the US$100 mark for the first time since May.

The rise has been linked to attacks on vessels in the Gulf, tightening supply following the closure of Saudi Arabia’s East-West crude pipeline which has put about 4 million barrels per day at risk, and heightened geopolitical tension between the US and Iran.

Prices of refined products also surged, with petrol up by 13.21%, diesel by 7.50% and LPG by 16.42%.

The Ghanaian cedi also depreciated by 1.01% to GH¢11.4849 to the US dollar between August 27 and September 11, putting additional pressure on prices.
