Why Fuel Prices Change So Frequently in Ghana

A 2026 Intelligence Brief from Accra Street Journal

For the average Ghanaian driver or household, the frequency of fuel price changes can feel bewildering. Just as you get used to one price at the pump, another adjustment arrives—sometimes down, often up. This is not administrative chaos. It is the direct result of a carefully structured deregulated pricing framework that ties domestic fuel prices to volatile global markets through a rigid bi-weekly review cycle .

This ASJ report explains the mechanics behind Ghana’s frequent fuel price changes, analysing the regulatory framework (the bi-weekly pricing window), the structural drivers (Ghana’s status as a net importer, exchange rate volatility, global crude dynamics), the policy layer (the price floor debate), and the competitive dynamics that amplify price movements. The evidence suggests that frequent price changes are not a bug in Ghana’s system—they are a feature. And they will persist as long as Ghana remains a net importer of petroleum products .

Part 1: The Regulatory Framework — The Bi-Weekly Pricing Window

The legal foundation for Ghana’s frequent fuel price adjustments is the National Petroleum Authority (Prescribed Petroleum Pricing Formula) Regulations, 2012 (L.I. 2186) , which established a deregulated pricing framework . Under this framework, fuel prices are not set by government decree but are determined by market forces—within a regulated structure.

The Two Pricing Windows

The NPA operates two pricing windows per month :

Every two weeks, Oil Marketing Companies (OMCs) recalculate their ex-pump prices based on:

• The average Free On Board (FOB) price of refined products over the preceding reference period

• The exchange rate between the cedi and the US dollar

• Suppliers’ Premiums (charged by Bulk Import, Distribution, and Export Companies)

• Statutory taxes and levies

• Distribution margins

At the beginning of each pricing window, the NPA publishes a price floor—the minimum price below which no OMC may sell . OMCs are then free to price above that floor, creating space for competition.

COMAC’s Price Outlooks

The Chamber of Oil Marketing Companies (COMAC) publishes bi-weekly price outlooks that forecast expected price movements. According to COMAC CEO Dr Riverson Oppong, these outlooks “have no doubt that for the past three to four windows, we’ve forecasted a lower or reduction in fuel price” .

When prices change at the pump, they are rarely surprises to industry participants. The frequency of changes is dictated by the calendar—every two weeks, predictable and scheduled .

Part 2: The Structural Drivers — Why Prices Move

The frequency of price changes is determined by the pricing window. The magnitude of those changes—whether prices rise or fall—is determined by three structural drivers.

Driver 1: Ghana’s Net Importer Status

Ghana consumes approximately 4 billion litres of petroleum products annually but refines less than 30% of its needs domestically. The Tema Oil Refinery (TOR) operates below capacity, and the country relies on imports for the majority of its fuel supply .

COMAC CEO Riverson Oppong has been unequivocal about the implication: “You cannot expect to have cheaper fuel in a country where we are a net importer, and a huge net importer for that matter” . He notes that even Nigeria, with the massive Dangote Refinery, has experienced significant fuel price increases because the global nature of petroleum pricing affects all import-dependent nations.

The arithmetic: When Ghana imports fuel, the price paid is determined by the FOB price at the time of purchase. If global prices rise between the reference period and the pricing window, Ghanaian consumers feel that increase within weeks—not months.

Driver 2: Exchange Rate Volatility

The pricing formula converts the dollar-denominated FOB price into cedis using the prevailing exchange rate. When the cedi weakens against the dollar, the landed cost of fuel rises immediately .

The National Petroleum Authority (NPA) confirmed in January 2026 that the persistent cedi pressures over the past year have been a primary driver of frequent price hikes . Consumers have faced frequent price increases “largely driven by currency pressures and volatility in international markets” .

The double volatility problem: Global oil prices and the cedi-dollar exchange rate are both volatile. When they move in the same direction—rising together—consumers face sharp, frequent increases. When they move in opposite directions, the effects can partially cancel, but the frequency of adjustments remains.

Driver 3: Global Crude and Refined Product Prices

The FOB price component of the pricing formula tracks international refined product markets. The Russia-Ukraine war, Middle East tensions, and OPEC+ production decisions all affect Ghana’s pump prices.

The most dramatic recent example is the Strait of Hormuz closure following US-Israeli strikes on Iran. With approximately 20% of global oil supply transiting the strait, crude prices surged to about $107 per barrel in early 2026 . This translated directly into higher projected pump prices in Ghana.

The projection: In May 2026, COMAC projected that without government intervention, petrol could reach GH¢15.80 per litre and diesel could climb to GH¢18.05 per litre . With government absorbing some costs (GH¢2.00 per litre on diesel, GH¢0.36 per litre on petrol), the increases were moderated—but not eliminated.

The Pricing Formula in Practice

The Chamber of Petroleum Consumers (COPEC) has broken down the formula :

• Ex-Refinery Price = FOB Price + Suppliers’ Premium

• Ex-Pump Price = Ex-Refinery Price + Taxes + Levies + Distribution Margins + Price Stabilization Margin

Each component can change between pricing windows. The Suppliers’ Premium, which covers discharge fees, storage, financing costs, and demurrage, is particularly sensitive to port efficiency and logistical bottlenecks—factors that Ghana has struggled to address.

Part 3: The Policy Layer — The Price Floor Debate

The price floor is the most controversial feature of Ghana’s fuel pricing regime. It does not cause price changes, but it shapes their magnitude and public perception.

What the Price Floor Does

Introduced in April 2024, the price floor sets a minimum retail price for petrol, diesel, and LPG, reset every two weeks based on import costs, taxes, port charges, and regulatory levies . OMCs must sell above that level, even when procurement costs fall.

The NPA’s justification: The Authority has defended the policy on three grounds :

1. Market stability: Prevents predatory pricing by large OMCs that could drive smaller competitors out of business

2. Supply security: Ensures the industry remains viable so fuel is available nationwide

3. Long-term consumer protection: Prevents monopolies that could later exploit consumers

The NPA’s director of economic regulation and planning, Abass Tasunti, stated in January 2026 that “the National Petroleum Authority has no plans to remove this policy,” warning that removing the floor could lead to uneven pricing among operators and supply disruptions .

Why the Floor Intensifies Price Change Perceptions

Critics argue that the floor prevents full pass-through of global price drops to consumers. Star Oil CEO Philip Tieku has stated that without the floor, his company could sell petrol as low as GH¢9.50 per litre during off-peak hours (10pm to 4am)—a significant discount from current prices .

When global prices rise, consumers see the full increase reflected at the pump. When global prices fall, the floor limits how much OMCs can cut. This asymmetry means that over time, prices ratchet upward more easily than they decline—even though the frequency of changes remains bi-weekly .

The COMAC-Star Oil Split

Star Oil has been so frustrated with the price floor that it indefinitely suspended its membership in COMAC in January 2026, citing “unfair representation” within the Chamber . The company argues that COMAC’s positions favour larger, less efficient players at the expense of consumers.

COMAC CEO Dr Riverson Oppong has dismissed suggestions that the price cuts seen in January 2026 were unusual, arguing they were a natural outcome of market competition. “What we are seeing today, I will say, was expected,” he stated . He acknowledged the aggressive price competition between GOIL and Star Oil, describing them as “the Tigers and the lions fighting, making the whole country messed up with too much noise around the topic.”

Part 4: The Competitive Layer — The GOIL-Star Oil “Saga”

The frequency of price changes is a matter of calendar and formula. But the visibility of those changes—and the public debate they generate—is amplified by fierce competition between Ghana’s two largest OMCs.

The Market Leaders

In January 2026, GOIL and Star Oil engaged in sharp price reductions that triggered reactions across the downstream sector. GOIL cut petrol prices from GH¢10.99 to GH¢9.99 per litre. Star Oil followed with reductions to GH¢9.97 per litre for petrol and GH¢10.97 per litre for diesel .

The Consumer Impact

This “healthy, unhealthy war” between the two giants  means that consumers see price changes that are not solely driven by global markets and exchange rates—they also reflect competitive dynamics. When Star Oil or GOIL chooses to cut prices aggressively, other OMCs must follow or lose market share. When margins are squeezed, the frequency of adjustments may increase as companies jockey for position.

However, the price floor prevents either company from cutting too deeply, ensuring a minimum level of profitability across the sector—and also ensuring that consumers never see the full benefit of global price drops.

Part 5: The Infrastructure Layer — Hidden Costs That Drive Frequency

Behind the visible price changes are hidden infrastructure constraints that make the market more volatile.

The Suppliers’ Premium

The Suppliers’ Premium—which includes off-loading charges, in-transit losses, inspection fees, letters of credit costs, financing costs, storage and rack loading costs, in-plant losses, and demurrage—is a direct function of infrastructure adequacy . Inadequate storage facilities, inefficient port operations, and logistical bottlenecks inflate this premium.

When vessels are delayed and cannot discharge because of port congestion or lack of storage capacity, demurrage costs accumulate—and these costs are passed directly to consumers in the next pricing window.

The BOST 24-Hour Distribution Pilot

BOST Energies has been selected to pilot 24-hour fuel distribution along the Accra Plains Depot (APD)-Kumasi corridor as part of the government’s 24-Hour Economy Programme [citation:?]. If successful, this could reduce demurrage costs by enabling faster turnaround of fuel trucks and more efficient supply chain management.

However, infrastructure deficits remain a structural constraint that no amount of regulatory adjustment can eliminate. As long as Ghana lacks sufficient strategic storage and efficient port operations, the Suppliers’ Premium will remain volatile—and fuel prices will continue to change frequently.

Part 6: The Outlook — Will Price Changes Become Less Frequent?

Near-Term: Continued Volatility

Several factors suggest that frequent price changes will persist in the near term:

Medium-Term: Potential Stabilisers

COMAC has stated that periodic increases in fuel prices are unavoidable as long as Ghana relies heavily on imported petroleum products . Without a significant increase in domestic refining capacity or a reduction in import reliance, the frequency of price changes will not decline.

Government Intervention as a Mitigating Factor

In response to the sharp price increases driven by the Middle East conflict, the government absorbed GH¢2.00 per litre on diesel and GH¢0.36 per litre on petrol in April 2026 . This intervention was designed to shield consumers from the full impact of global price shocks—but it came at a significant fiscal cost.

If such interventions become routine, they could dampen the frequency of price changes visible to consumers. However, the government has shown that it will not—and cannot—absorb all volatility. The NPA’s insistence on retaining the price floor suggests a preference for managed volatility over unmanaged chaos.

Conclusion: The Logic of Frequent Change

Fuel prices in Ghana change frequently because the pricing system is designed to reflect market realities. The bi-weekly pricing window ensures that changes in global oil prices, the exchange rate, and suppliers’ costs are passed through to consumers with minimal lag . This is not administrative failure—it is policy choice.

The 2015 deregulation ended the era of subsidised, government-administered prices and the budget deficits they created. The trade-off was exposure to global volatility. When crude prices rise or the cedi weakens, consumers feel the impact quickly. When prices fall, consumers benefit quickly—though the price floor limits how much of that benefit can be passed on .

The debate over the price floor reflects a fundamental tension: the floor protects smaller OMCs from predatory pricing and maintains supply security, but it also prevents full pass-through of favourable market movements . The NPA has made clear that it has “no plans to remove this policy” .

Frequent fuel price changes are not a temporary phenomenon. They are the logical consequence of Ghana’s integration into global petroleum markets. As COMAC’s CEO noted, “You cannot expect to have cheaper fuel in a country where we are a net importer” . Until Ghana significantly expands domestic refining capacity—or until the cedi achieves sustained stability—Ghanaians should expect to see pump prices adjust every two weeks. That is not a flaw in the system. It is the system working as designed.

Quick Reference: Why Fuel Prices Change Frequently

FAQ Section

Q1: How often do fuel prices change in Ghana?
A: Fuel prices are reviewed every two weeks, with pricing windows from the 1st to the 15th and from the 16th to the end of each month .

Q2: What is the fuel price floor and why does the NPA enforce it?
A: The price floor is a minimum retail price set by the NPA that OMCs cannot sell below. It exists to prevent predatory pricing, protect smaller OMCs, ensure supply security nationwide, and prevent monopolies that could later exploit consumers .

Q3: Will the NPA remove the price floor?
A: As of January 2026, the NPA stated it has “no plans to remove this policy,” warning that removing the floor could lead to uneven pricing and supply disruptions .

Q4: Why does Ghana’s fuel pricing depend on global markets when we have oil?
A: Ghana exports crude oil but imports refined petroleum products because the Tema Oil Refinery operates below capacity. As a net importer of finished products, Ghana is exposed to global refined product prices .

Q5: What is COMAC’s role in fuel pricing?
A: The Chamber of Oil Marketing Companies (COMAC) publishes bi-weekly price outlooks, forecasts price movements, and represents the interests of OMCs. According to COMAC, its price reductions were “long anticipated” and consistent with industry forecasts .

Q6: Why did Star Oil suspend its COMAC membership?
A: Star Oil suspended its membership in January 2026, citing “unfair representation” within the Chamber. The company argues that the price floor prevents it from passing cost savings to consumers .

Q7: How does the exchange rate affect fuel prices?
A: The pricing formula converts dollar-denominated FOB prices into cedis. When the cedi weakens against the dollar, the landed cost of fuel rises immediately, leading to higher pump prices .

Q8: What was the government’s fuel price intervention in 2026?
A: In April 2026, the government absorbed GH¢2.00 per litre on diesel and GH¢0.36 per litre on petrol to shield consumers from price spikes driven by the Middle East conflict .

Q9: How does the Strait of Hormuz closure affect Ghana’s fuel prices?
A: Approximately 20% of global oil supply transits the Strait of Hormuz. The closure following US-Israeli strikes on Iran sent crude prices to about $107 per barrel, directly affecting Ghana’s FOB import costs .

Q10: Will Ghana ever stop changing fuel prices so frequently?
A: As long as Ghana remains a net importer of petroleum products, fuel prices will continue to be influenced by global market dynamics. COMAC has stated that frequent adjustments are “unavoidable” until Ghana significantly increases domestic refining capacity
