Petroleum prices are likely to come under renewed pressure at the pumps from September 1, 2026, after the National Petroleum Authority (NPA) increased the approved price floors for petrol and diesel for the September 1–16 pricing window.
The NPA has raised the minimum price for petrol from GH¢13.92 to GH¢14.53 per litre, representing an increase of about 4.38% over the previous benchmark.
The price floor for diesel has also been increased from GH¢15.19 to GH¢15.60 per litre, an increase of 2.69%.
Liquefied Petroleum Gas (LPG), however, recorded a marginal reduction, with its price floor falling from GH¢10.98 to GH¢10.85 per kilogramme.
The new floors mean Oil Marketing Companies (OMCs) and LPG Marketing Companies (LPGMCs) will not be permitted to sell the affected products below the NPA-approved minimum prices during the pricing window.
NPA clarifies price-floor structure
In its notice, the NPA reminded industry players of the requirement to comply with the approved price floors.
The Authority, however, explained that the price floors do not include premiums charged by International Oil Trading Companies (IOTCs), operating margins of Bulk Import, Distribution and Export Companies (BIDECs), or the marketers’ and dealers’ margins of OMCs and LPGMCs.
Those components, the NPA said, would continue to be independently determined by the respective companies in accordance with the Price Petroleum Products Pricing Guidelines (PPPG).
This means the new price floors do not necessarily represent the final prices consumers will pay at filling stations.
Pump prices may remain unchanged
Despite the increase in the NPA’s benchmarks, the development does not automatically mean that fuel prices will rise across all filling stations from September 1.
Some OMCs have indicated that pump prices could remain unchanged at the start of the new pricing window, depending on their commercial decisions and prevailing market conditions.
OMCs are expected to assess competition and other market factors over the weekend and into Monday before determining their prices.
However, the possibility of increases remains significant because several OMCs are already selling petrol and diesel well above the current price floors.
With more than 200 OMCs operating in Ghana, pricing decisions are expected to vary depending on individual companies’ margins, supply costs and competitive strategies.
Diesel subsidy remains uncertain
The outlook for diesel prices is further complicated by uncertainty surrounding the government’s temporary intervention at the pumps.
On August 3, 2026, the government announced that it would absorb GH¢2 per litre of the price of diesel as a measure to cushion consumers.
The intervention was announced as a one-month relief, raising questions about whether it will be extended into September and whether it contributed to moderating the increase in the diesel price floor.
The Energy and Green Transition Minister, John Abdulai Jinapor, has already indicated that the measure was intended only for August and would be reviewed before any decision is made on its continuation.
Without an extension of the subsidy, consumers could face greater exposure to the impact of the revised diesel benchmark from September.
Global market, margins to shape final prices
The NPA’s adjustment of the price floors provides a new benchmark for the September 1–16 window, but actual pump prices will depend on a combination of factors.
These include international oil prices, exchange-rate movements, taxes and levies, trading premiums, operating costs and the margins applied by individual OMCs.
The distinction between the NPA price floor and actual pump prices is particularly important because many marketers currently sell above the regulatory minimum.
Consequently, even a modest increase in the benchmark could translate into higher retail prices where companies adjust their margins or pass on higher supply costs.
For consumers, the key issue will be whether OMCs absorb the latest increase or pass it through to motorists.
The higher petrol and diesel benchmarks also come at a time when transport operators, households and businesses remain sensitive to changes in fuel prices because of their broad impact on transportation, logistics, food distribution and production costs.
While LPG consumers have received some relief through the reduction in its price floor, motorists using petrol and diesel will be watching the pricing decisions of OMCs closely as the new window begins on September 1, 2026.
The latest NPA adjustment therefore sets the stage for potentially higher fuel prices, although the final outcome at the pumps will depend on individual marketers, market competition and the government’s decision on whether to extend its temporary diesel subsidy.
