Lower fuel prices can swiftly translate into lower overall costs in many African countries where road transport transports labor, food, and merchandise across large distances.

According to Reuters, the country's gas prices decreased dramatically between June and July, slowing annual inflation to 4.3% in July from 5% in June.

Lower gasoline prices lower the cost of operating automobiles, taxis, buses, and delivery trucks.
