Accra: Ghanaian businesses and households alike, as well as government itself, are bracing up for new price shocks as the renewed surge in the Brent crude oil benchmark above US$100 per barrel in the second week of September 2026 is likely to create a fresh inflationary test for Ghana, this coming at a time that domestic price pressures had begun to moderate.
According to Ghana Web, Brent settled at US$101.21 per barrel on September 9 and subsequently traded above US$105, reaching almost US$110 intraday on September 11 before retreating. The immediate trigger is the sharp deterioration in the Middle East security environment and the threat to oil flows through the Strait of Hormuz and other strategic shipping routes. Brent was still around US$90-92 during the period used to determine Ghana's first September pricing window.
For Ghana, therefore, the important issue is not simply that crude has crossed the psychologically significant US$100 threshold. It is that the increase has occurred after the price-setting inputs for the first September window had largely been established. This means the full effect is more likely to emerge in the second pricing window, beginning September 16. Instructively the expected petroleum price hikes will come just a few days before Ghana's biggest commercial road transport union, the GPRTU, may implement a 30 percent increase in transport fares - from September 21 - citing rising fuel and other operating costs.
The first September window already demonstrated the extent to which international petroleum prices were putting pressure on the Ghanaian market. The National Petroleum Authority raised the petrol price floor from GHc13.92 to GHc14.53 per litre and the diesel floor from GHc15.19 to GHc15.60. At the same time, Government retained a GHc2-per-litre reduction in the regulatory margin on diesel to moderate the impact on consumers.
OMCs initially responded cautiously. GOIL, for example, maintained petrol at GHc15.43 and diesel at GHc17.26 per litre, while Star Oil subsequently moved to the same GHc15.43 petrol and GHc17.26 diesel levels. TotalEnergies was charging GHc16.18 for petrol and GHc17.59 for diesel.
The Chamber of Petroleum Consumers (COPEC) has already warned that the Brent price surge is likely to push Ghanaian pump prices higher from September 16. Its Executive Secretary, Duncan Amoah, has pointed out that crude-price movements take some time to pass through the refining, shipping, and importation chain.
A reasonable working scenario is therefore for petrol and diesel prices to rise by roughly 5-10 percent during the second September window, assuming Brent remains around US$100-110 and the cedi does not suffer a major depreciation. The precise adjustment will depend on the average international refined-product prices, freight and insurance premiums, the exchange rate, and the extent to which OMCs absorb part of the increase.
The impending oil shock is coming at a delicate point in Ghana's disinflation process. Consumer inflation fell from 5.3 percent in June to 4.6 percent in July-the first decline since March. However, producer-price inflation moved in the opposite direction, rising from 3.5 percent in June to 4.0 percent in July. Consumer inflation then proceeded to rise again, to 5.0 percent in August, driven largely by transport and utility costs.
The announced intention by commercial transport operators to raise fares is therefore potentially more consequential than the direct increase in fuel prices. The GPRTU has announced a proposed 30 percent increase in transport fares from September 21, citing rising fuel and other operating costs.
Government has several options, although none is cost-free. It can temporarily extend or increase the diesel intervention, target the intervention to specific sectors, or engage OMCs to moderate margins temporarily. However, suppressing fares administratively could transfer financial problems to drivers and owners.
For Ghana, a temporary Brent price of US$100 is uncomfortable but manageable. The more serious threat would be Brent remaining above US$100 for several months. If geopolitical disruptions keep crude around US$105-120, the impact would increasingly migrate from filling stations into transport, food, manufacturing, and household budgets.
