Several Oil Marketing Companies (OMCs) have begun increasing retail prices for petroleum products as of this morning, June 1, 2026, marking the start of the latest two-week deregulation pricing window.

Star Oil led the implementation this morning, raising its petrol price to GH¢15.20 per litre, up from the GH¢14.60 per litre rate set on May 16.

The company maintained its diesel price at GH¢15.81 per litre. It remains unconfirmed how other major market competitors, including GOIL, Shell, Total, and Zen Petroleum, will adjust their pump prices in response.

The price adjustments follow the National Petroleum Authority’s (NPA) May 28 announcement of the official price floors for the June 1 to June 16 window.

The NPA directive mandates that no OMC sell a litre of petrol below GH¢15.20, representing an increase from the previous window. Conversely, the official floor price for diesel was set at GH¢15.49 per litre, down from the May 16 directive.

Industry Projections

According to projections by the Chamber of Oil Marketing Companies (COMAC) for firms purchasing products on credit from Bulk Oil Distributors:

- Petrol: Expected to rise between 4.20% and 6.20%, potentially reaching up to GH¢15.92 per litre.

- LPG: Expected to increase by up to 2.24%, bringing the cost to GH¢17.30 per kilogramme.

- Diesel: Expected to decrease between 1.65% and 2.00%, resulting in an estimated price of GH¢17.20 per litre.

Drivers of the Price Changes

COMAC attributed the mixed pricing outlook to a combination of lower global market prices, persistent pressure on the Ghana cedi, and ongoing state-industry interventions.

A joint government-industry intervention mechanism, extended on May 16, continues to influence pump prices.

Under the current revision, the intervention has been zeroed out for petrol and reduced to GH¢1.07 for diesel.

According to COMAC, this mechanism is intended to progressively transition local rates toward international market standards while cushioning consumers from the immediate impact of higher global prices.
