Global oil markets have been impacted by a renewed confrontation between the US and Iran, with vessel traffic through the Strait of Hormuz significantly reduced. This disruption, combined with attacks on regional energy infrastructure and shipping, has driven Brent crude above $100 per barrel in September 2026. Despite this, Ghanaian pump prices have remained relatively stable, with a 4.38% increase in petrol prices and a 2.69% increase in diesel prices.
The Institute for Energy Security (IES) attributes Ghana's relative calm to deliberate policy choices and macroeconomic conditions. Ghana imports over 60% of its petroleum products, making fuel prices closely tied to international crude movements and the strength of the cedi. The IES notes that a stable cedi, lower inflation, and targeted government interventions have cushioned the impact of the global oil market turmoil on Ghanaian consumers.
The cedi has remained relatively stable, with an appreciation of 2.39% against the dollar from January to August 2026. This stability has helped prevent a second shock from stacking on top of the first. Inflation has also decreased, with headline inflation at 5.0% in August 2026, down from previous high-inflation years. The Bank of Ghana credits this disinflation to tight monetary policy, fiscal consolidation, and the cedi's recovery.
The government has implemented temporary measures to absorb some of the shock, including a one-month absorption of GH¢2.00 per litre on diesel and GH¢0.36 per litre on petrol introduced on 16 April. A fresh GH¢2.00-per-litre reduction in the diesel regulatory margin was restored from 4 August and extended into the first September pricing window. These interventions have helped mitigate the impact of the global oil market turmoil on Ghanaian consumers.
Despite these buffers, fuel prices in Ghana have still increased. The National Petroleum Authority (NPA) reported a 4.38% increase in petrol prices and a 2.69% increase in diesel prices in September. The IES ran a stress test to illustrate how much worse things could have been if the cedi had depreciated, inflation had risen, and government relief measures had been removed.
The NPA has acknowledged Ghana's exposure to global oil market volatility, with CEO Godwin Tamakloe stating that the country's heavy reliance on imported petroleum means price volatility is built into the system. The NPA has also frozen a proposed transport fare hike, reflecting concern over how far fuel-driven costs might spread into transport fares.
The situation in the Strait of Hormuz remains a concern for Ghanaian households, transport operators, and businesses. Any further escalation in the Gulf that keeps Brent above $100 a barrel could raise the dollar cost of fuel imports, leading to potential price increases at the pump. The impact will depend on whether the cedi holds steady, inflation stays contained, and government relief measures remain in place.
