- Oil Shock Shifts Ghana’s Currency Risk from Cedi Depreciation to Petroleum Dollar Demand
Ghana’s cedi has remained relatively stable against the US dollar despite a sharp global energy shock, but rapidly rising petroleum import costs are opening a new source of pressure for inflation, foreign-exchange demand and the country’s monetary-policy outlook.
The Bank of Ghana’s interbank reference rate published on Tueday showed the currency at GH¢11.4767 buying and GH¢11.4881 selling per dollar, producing a weighted median rate of GH¢11.4824 from transactions on September 15. The movement remains contained and does not yet point to disorderly foreign-exchange conditions.
The more significant development is occurring outside the spot currency market.
International crude prices rose from approximately US$89.30 to US$103.07 per barrel during Ghana’s latest petroleum pricing window, according to the Chamber of Petroleum Consumers, while the cedi actually appreciated by about 0.29% on the pricing-period average, moving from GH¢11.5166 to GH¢11.4830 per dollar.
Despite that currency support, the international free-on-board price of petrol increased 10.08%, while diesel rose 12.33%. COPEC consequently projected petrol prices to climb 4.24% to an average GH¢16.26 per litre and diesel to increase 10.23% from GH¢17.30 to GH¢19.07.
The divergence is important for Ghana’s macroeconomic outlook. For much of the recent inflation discussion, attention has focused on the cedi because depreciation raises the local-currency cost of imported fuel, food, machinery and intermediate goods.
The current episode shows that even a broadly stable currency cannot insulate the economy when the underlying dollar price of a critical import rises sharply. That shifts the immediate risk from the exchange rate itself towards the size of petroleum-sector dollar requirements.
Importers may need significantly more foreign currency to finance the same physical volume of fuel if crude and refined-product prices remain elevated. Sustained increases in those dollar requirements could eventually feed back into the FX market, particularly if demand coincides with other seasonal or commercial foreign-exchange pressures.
Diesel presents an especially difficult risk. Asian refining margins for 10-parts-per-million sulphur diesel have surged above US$87 per barrel, an all-time high and almost four times the roughly US$22 level recorded before the latest Middle East disruption.
Asian refiners have responded by raising output and sending additional cargoes as far as Africa to address tightening supply elsewhere. The implication is that Ghana could face expensive diesel imports even when crude prices retreat.
Refined-product prices do not move mechanically with Brent. Refinery availability, freight costs, regional inventories, supply disruptions and product-specific demand can all keep diesel prices elevated after the underlying crude benchmark has eased.
There was some relief in oil markets on September 16. Brent settled 2.69% lower at US$105.83 per barrel after Saudi Arabia offered additional crude through Oman, while concerns over Middle East supply infrastructure and shipping routes remained elevated.
But the broader energy market remains tight. Reuters reported that industry executives at Shell and Equinor see traditional shock absorbers weakening after substantial crude and LNG supply losses, raising the possibility that heightened volatility could persist into 2027.
For Ghana, the next transmission channel is inflation. Higher diesel prices affect haulage, public transport, agriculture, mining, construction, electricity generation outside the grid and the distribution of goods across the country.
Petrol increases household transport costs directly. Businesses faced with sustained increases in fuel and logistics expenses will eventually have to decide how much of those costs they can absorb before passing them to consumers.
Apakan Securities has already warned that renewed cedi weakness alongside higher fuel prices could lift Ghana’s September inflation reading and potentially restrict the Bank of Ghana’s scope for additional monetary easing.
That poses a complication for monetary policy. Ghana has been attempting to move from stabilisation towards stronger investment and growth as inflation moderates from previous highs. A renewed imported-energy shock could slow that transition if it forces the central bank to remain cautious on interest rates while simultaneously raising operating costs for businesses.
There is also an emerging fuel-security dimension. BOST Energies has reduced some fuel exports to Burkina Faso and Mali to prioritise domestic requirements amid tighter global supplies, according to Reuters. The state-owned company supplied Burkina Faso only 40,000 tonnes against requests for 80,000 tonnes for July and August and delivered 10,000 tonnes to Mali against a requested 50,000 tonnes.
Elsewhere in West Africa, Nigeria’s naira has remained relatively contained. The latest official NFEM rate was about NGN1,329.15 per dollar, compared with parallel-market quotations around NGN1,380 buying and NGN1,385 selling. Official-market turnover also rose sharply to US$262.12 million from US$94.4 million, providing little immediate indication of a regional FX dislocation spreading from Nigeria.
For Ghana, however, stability around GH¢11.48 should not be interpreted as the absence of currency risk.
The cedi has so far absorbed the global energy shock remarkably well, but the pressure is migrating through a different channel. The key question is whether Ghana can finance substantially more expensive petroleum imports without that increased dollar demand eventually spilling into the exchange rate.
A sustained move above GH¢11.50-GH¢11.60 per dollar, particularly alongside wider interbank-retail spreads or stronger petroleum-sector demand, would signal that the external energy shock is beginning to migrate from imported inflation into the FX market itself.
For now, the cedi remains contained. The bigger test is whether it can stay that way as Ghana pays a much higher dollar price to keep fuel moving through the economy.
