Ghana Just Cut Diesel by GH¢1.80. But Cooking Gas Is Going Up.
Ghana's National Petroleum Authority set new fuel and LPG price floors for the May 1 to May 15 window. Diesel falls by GH¢1.80 a litre. Petrol drops two pesewas. But cooking gas jumps GH¢2.23 a kilo. That mix changes the math for delivery vans, lorries, food vendors, and chop bars in different directions on the same day.
What Changed on May 1
The National Petroleum Authority (NPA) is Ghana's downstream petroleum regulator. Every two weeks it sets ex-pump price floors that Oil Marketing Companies (OMCs) must respect. On April 28, 2026 it published the floors for the May 1 to May 15 window.
The new floors:
| Product | New floor | Change vs mid-April |
|---|---|---|
| Petrol | GH¢13.25 per litre | Down 2 pesewas |
| Diesel | GH¢14.30 per litre | Down GH¢1.80 |
| LPG (cooking gas) | GH¢13.02 per kilogram | Up GH¢2.23 from GH¢10.79 |
GOIL and Star Oil were the first OMCs to publish their May rates. Both held petrol at GH¢13.25. GOIL set diesel at GH¢15.66, down 44 pesewas. Star Oil set diesel at GH¢15.55, down 55 pesewas. Retail prices sit above the NPA floor because OMCs add their own margins. Other OMCs were expected to adjust within days.
The NPA reminded all OMCs and LPG marketing companies to stay at or above the announced floors. Pump prices can still vary station by station based on those margins.
Diesel Relief for Lorries and Trotros
Diesel is the fuel that moves goods. Lorries that bring tomatoes from Techiman to Accra run on diesel. Trotros that deliver wholesale provisions to Madina and Kasoa run on diesel. Generators behind half the shops in any town run on diesel.
A GH¢1.80 cut in the floor is real money on a full tank. A 50-litre tank now costs about GH¢90 less than at the mid-April peak. For a delivery van running two full tanks a week, that is GH¢180 saved every week, or roughly GH¢720 a month before margins.
This matters most for Techiman, Kumasi, and Tamale traders who flagged in mid-April that fuel costs were forcing them to mark up tomatoes, onions, yam, and plantain. The diesel drop will not reverse those markups overnight. Wholesalers usually wait a full pricing window or two before passing relief through. But the direction has flipped.
One thing to watch: traders who bought stock when diesel was at the GH¢17.10 April peak are now sitting on goods costed at the old transport rate. Some will need to clear that stock at a small loss before the new lower rate shows up in shelf prices.
The Cooking Gas Hike Will Hurt Food Vendors
LPG up GH¢2.23 a kilo is the bigger story for anyone who cooks for sale. A standard 14.5 kg domestic cylinder that cost about GH¢156 to refill in mid-April will now cost about GH¢189. That is a GH¢33 jump per cylinder. A chop bar that swaps two cylinders a week is paying GH¢66 more this week than last.
This hits hardest:
- Chop bars and food joints — waakye, banku, kenkey, fufu, jollof. All cooked on LPG.
- Roadside grills and koko sellers — kelewele, kebab, khebab, koko. Most have moved off charcoal to gas in the past five years.
- Bakeries and pastry shops — gas ovens running all morning.
- Cold stores and small frozen-food retailers — gas-powered backup when ECG light goes off.
- Households — middle-income families that switched from charcoal will feel it on the monthly food bill.
The Herald Ghana flagged the LPG surge as the most painful single line in the May window. The NPA has not given a public reason for the size of the LPG move, but traders point to global LPG benchmarks moving differently from crude in recent weeks, plus cedi pressure.
Why Petrol Barely Moved
Petrol came down only two pesewas. That is a rounding error. Boda riders, taxi drivers, and most private cars use petrol. So the relief is real but small for that group.
Two reasons petrol moved less than diesel:
- Diesel had spiked sharply in April when Middle East tensions pushed gas oil benchmarks up. It had more room to fall back. Petrol stayed closer to its trend line.
- The cedi is also part of the price formula. Movements in the cedi-dollar rate can offset crude price drops product by product.
The NPA's CEO has warned in recent weeks that fuel pricing remains volatile while the Middle East situation drags on. Ghana now holds about seven weeks of fuel stock, so a sudden global jump would not show up at the pump for at least one full pricing window.
What This Means for Other African Markets
Ghana is not alone in re-pricing fuel for May. Kenya saw a record diesel jump in mid-April and the Treasury cut VAT in response. South Africa's R3-a-litre fuel levy cut ends on May 6, 2026, with diesel projected to jump over R7 a litre if the cut is not extended. Nigeria's Lagos traders flagged in late April that fuel and logistics costs were pushing food prices up at the wholesale stage.
Across the region, the pattern is the same. Diesel and LPG do not move together. A drop in one does not mean relief in the other. Shop owners in Lagos, Nairobi, Kampala, and Dar es Salaam should run the same check Ghanaian traders are running this week: which fuel actually drives my cost, and is that fuel up or down right now?

5-Step Action Plan for Ghanaian Shop Owners
- Refill diesel tanks now if you run a generator or delivery van. The May 1 to 15 window may not last. If global crude moves up before May 15, the next window could undo the relief.
- Buy two cylinders of LPG at a time if your chop bar runs through gas fast. Lock in today's GH¢189 refill before retailers add their own margin on top of the new floor.
- Hold off on raising your menu prices on the back of LPG alone. Customers who tolerate one price hike may walk if you raise prices in the same week diesel went down. Wait one week, see what other chop bars do, then move.
- Talk to your wholesaler about pass-through. Diesel relief should reach you within one to two weeks on goods you buy by the carton. Ask. Do not assume.
- Keep a small notebook of pump prices and cylinder refill costs every week. When the next NPA window arrives on May 16, you will know exactly how much your costs really moved, not just the headline figure.
Why This Matters
Fuel is not one input. It is at least three different inputs that move on different schedules. Diesel funds your transport. LPG funds your cooking. Petrol funds your boda or taxi run to the wholesaler. Treating them as one number is how shop owners get squeezed.
The May 1 reset gives Ghanaian traders a small window to plan ahead. The diesel drop is a chance to clear old stock at the old transport rate without raising prices. The LPG hike is a warning that food vendors must reprice carefully or take the loss on margin for two weeks. Either choice is fine. Drifting into the window without making one is the expensive choice.
Conclusion
Ghana's May fuel window is not the relief it looks like at first glance. Diesel falls. Petrol holds flat. Cooking gas climbs. The smart shop owner reads the full table, not just the headline. The next NPA window opens on May 16. By then traders should know exactly which side of the price split helped them, and which side hurt.
