Ghana’s downstream petroleum market is heading into October under renewed price pressure, with diesel expected to record the steepest increase among the three major petroleum products, according to a projection by the Chamber of Petroleum Consumers (COPEC).
COPEC projects petrol to rise by 5.21%, diesel by 22.91%, while Liquefied Petroleum Gas (LPG) is expected to increase to GH¢15.68 per kilogramme in the first pricing window of October 2026.
The projected changes reflect a combination of higher international petroleum prices and a weaker cedi over the pricing period.
The projection places diesel at the centre of the latest downstream pricing pressure. While petrol is expected to experience a relatively moderate increase, the much sharper movement in diesel points to the uneven way international product-price changes can feed into Ghana’s domestic market.
Global Oil Prices Drive New Pressure
COPEC’s assessment attributes the expected increases primarily to movements on the international market.
The Chamber said global crude prices rose from US$103.07 per barrel to US$124 per barrel during the pricing window. At the same time, the cedi depreciated marginally against the US dollar, moving from an average interbank rate of GH¢11.4830 to GH¢11.6211.
The combination matters because Ghana’s downstream market remains exposed to international petroleum prices and foreign-exchange movements.
A rise in the dollar-denominated cost of petroleum products increases the underlying cost of imports, while depreciation raises the amount of cedis required to purchase those products.
That means even a relatively modest exchange-rate movement can reinforce an international price increase.
COPEC’s projection therefore illustrates how Ghana’s fuel-pricing pressures can emerge from two markets simultaneously: the international petroleum market, where crude and refined-product prices are determined, and the domestic foreign-exchange market, which determines the cedi cost of those purchases.
Diesel Carries Heaviest Increase
Diesel presents the sharpest pressure in COPEC’s projection.
The Chamber estimates that the international Free on Board (FOB) price of diesel increased from US$1,404.73 per metric tonne to US$1,524.22, representing an 8.51% increase. Combined with the 1.20% depreciation of the cedi, COPEC projects a retail price of GH¢22.42 per litre.
That would represent a 22.91% increase from the current mean price of GH¢18.24 per litre.
“The projected retail pump price for diesel in the next window shall work up to Ghc22.42/L representing 22.91% increase of the current mean price of Ghc18.24/L.”
Chamber of Petroleum Consumers (COPEC)
COPEC places the expected diesel price within a range of GH¢19.40 to GH¢21.44 per litre within a ±5% range of its projection.
The scale of the projected movement makes diesel particularly important for the wider economy because the product is closely connected to commercial transport and other economic activities.
Any sustained increase would therefore extend beyond the filling station, potentially increasing operating costs for businesses that depend on diesel.
Petrol Faces More Moderate Adjustment
Petrol is also expected to become more expensive, although the projected increase is considerably smaller than the movement anticipated for diesel.
COPEC estimates that the FOB price of petrol increased from US$1,251.07 per metric tonne to US$1,304.39, representing a 4.26% increase. After accounting for the cedi’s depreciation, the Chamber projects a retail price of GH¢17.78 per litre.
That would represent a 5.21% increase from the current mean price of GH¢16.90 per litre.
COPEC expects petrol to sell within a range of GH¢16.89 to GH¢18.67 per litre around its projection.
The difference between the projected petrol and diesel increases highlights an important feature of the current pricing environment: movements in the international market do not necessarily translate into uniform changes across petroleum products.
LPG Adds Household Energy Pressure
LPG is also expected to record a significant increase.
COPEC puts the international FOB price of LPG at US$777.59 per metric tonne, up from US$712.43, representing a 9.10% increase. Combined with the cedi’s depreciation, the Chamber projects an LPG retail price of GH¢15.68 per kilogramme.
The projected range is GH¢14.89 to GH¢16.48 per kilogramme within the Chamber’s ±5% margin.
The LPG movement adds another dimension to the downstream pricing challenge because LPG is not simply a transport fuel. It is also an important household energy product, meaning higher prices can affect household energy expenditure alongside the broader costs associated with petroleum products.
Local Refining Seen As Longer-Term Buffer
Beyond the immediate price outlook, COPEC’s recommendations point to a broader question for Ghana’s energy policy: how to reduce the country’s exposure to international refined-product markets.
The Chamber commended government for maintaining crude supplies to local refineries, which it said was supporting continuous refinery production.
It nevertheless argued that greater refining capacity would be necessary to meaningfully reduce dependence on imported finished petroleum products.
COPEC specifically called for faster expansion of the Tema Oil Refinery’s capacity from the current 45,000 barrels per day to 100,000 barrels per day.
“We believe this will go a long way in reducing our reliance on imported finished petroleum products.” Duncan Amoah, Executive Secretary, COPEC stated.
The recommendation is significant because domestic refining does not eliminate Ghana’s exposure to crude-price movements. However, increasing local refining capacity could alter the composition of that exposure by reducing reliance on imported finished products.
That distinction matters. Ghana could remain exposed to international crude prices while gaining greater control over some aspects of domestic petroleum supply, including the availability of refined products and the infrastructure required to process crude locally.
Marketers Urged To Absorb Part Of Pressure
COPEC has also appealed to Oil Marketing Companies (OMCs) to consider reducing part of their margins to limit the impact of the expected increases on consumers.
The Chamber said OMCs should consider “shelving some of their margins” rather than transferring the full pressure of the expected increases to consumers.
That proposal places part of the immediate burden on the downstream commercial chain, although the extent to which marketers can absorb higher costs depends on their own operating margins and the wider pricing structure.
The more fundamental issue remains the exposure of Ghana’s downstream market to external price movements and exchange-rate conditions.
Price Pressure Tests Energy Resilience
COPEC’s October projection comes down to a familiar vulnerability in Ghana’s petroleum market: international price movements can quickly become domestic cost pressures when the country remains exposed to imported petroleum products.
The projected 22.91% increase in diesel, alongside higher petrol and LPG prices, demonstrates how sharply individual products can respond when international prices rise.
For policymakers, the longer-term challenge is therefore not simply managing one pricing window. It is building a downstream system capable of absorbing external shocks without transferring their full impact to consumers.
COPEC’s emphasis on expanding domestic refining capacity points to one part of that equation, while its call for OMCs to moderate margins addresses the immediate pressure.
The Chamber’s projection ultimately places Ghana’s petroleum resilience at the intersection of three factors: international prices, exchange-rate stability and domestic refining capacity.
Until those vulnerabilities are reduced, global petroleum-market movements will continue to have a direct bearing on prices at Ghana’s pumps.
