When fuel prices fall, will the cost of living follow? For Ugandan households, the answer matters far beyond the petrol station. Fuel affects the cost of transporting food, moving goods, operating businesses and getting to work. When prices rise, the effects can spread across the economy. But when fuel becomes cheaper, consumers cannot always expect the costs of everyday goods and services to fall at the same pace.
Uganda is confronting that problem again. Petrol prices rose from around Shs5,090 a litre in March to an average of Shs6,642 in September, while diesel increased from about Shs5,090 to Shs6,757 over the same period. By early October, some petrol stations were charging about Shs6,950 a litre and now 7000,
The pressure is also visible in the inflation figures. Annual headline inflation rose to 4.6 per cent in September from 4.1 per cent in August. Petrol prices were 30.9 per cent higher than a year earlier, while diesel prices had risen by 42.5 per cent.
For households already managing transport, food, rent and school expenses, the concern is what happens next. If fuel prices retreat, will fares and supermarket prices follow, or will families continue paying more long after the original shock has eased?
Fuel is an input into almost every stage of the supply chain. Farmers and traders need transport to move produce; manufacturers rely on energy and logistics; retailers pay to bring goods from suppliers. Public transport operators and boda boda riders face fuel costs directly.
When fuel becomes more expensive, businesses must decide whether to absorb the increase or pass some of it to customers. The decision depends on their margins, competition, other operating expenses and how much customers can afford.
The reverse, however, is not automatic. A decline in fuel prices reduces one component of operating costs, but it does not necessarily reverse increases in wages, rent, vehicle repairs, financing or wholesale prices. Businesses may also be selling goods purchased when transport and production costs were higher.
The exchange rate adds another complication. Uganda imports petroleum products, meaning local prices depend on international prices for crude oil and refined products, alongside the shilling’s value against the dollar. A fall in global oil prices may therefore be partly offset by a weaker shilling, while stocks bought at higher prices can delay reductions at the pump.
These factors help explain why lower fuel prices may take time to feed through to the wider economy. They do not, on their own, establish that businesses are passing on increases quickly while deliberately withholding reductions. That requires evidence from actual prices, fares and business costs.
Uganda’s experience in 2022 offers a useful illustration of how fuel prices and the broader cost of living can move differently.
According to the Ministry of Energy and Mineral Development, petrol reached Shs6,590 a litre in July 2022, while diesel climbed to Shs6,313. By June 2023, petrol had fallen to Shs4,970 and diesel to Shs4,830.
Yet cheaper fuel did not return the economy to its previous price structure.
The distinction lies in the difference between inflation and the general level of prices. Inflation measures how quickly prices change; it does not measure whether goods have become affordable again.
If a household item rises from Shs5,000 to Shs6,000, a subsequent decline in inflation does not automatically bring it back to Shs5,000. It may simply mean the Shs6,000 price is increasing more slowly.
Uganda’s annual headline inflation averaged 7.2 per cent in 2022, compared with 2.2 per cent in 2021. Inflation subsequently eased, but that did not mean all the price increases experienced during the period were reversed.
This distinction explains why households can hear that inflation is falling and still feel that life is becoming more expensive. A slower rate of increase offers some relief compared with accelerating inflation, but it is not the same as a reduction in the prices people pay.
It is also important not to attribute every increase in food prices to fuel. Weather conditions, harvest volumes, seasonal supply and market access can all affect what consumers pay. UBOS reported that annual inflation for food crops and related items rose to 4.5 per cent in September from 2.1 per cent in August. That movement coincided with the fuel-price increase, but the figures alone do not establish how much of the change was caused by fuel.
The more difficult question is whether consumers benefit when businesses’ costs fall. A transport operator may have legitimate reasons to maintain fares after a fuel-price reduction, particularly if spare parts, maintenance and other expenses remain high. A trader may still be selling stock purchased at elevated wholesale prices. But if fuel costs fall substantially and other costs remain unchanged, consumers have reason to ask whether some of the savings should be reflected in lower prices.
Competition matters here. In markets where customers can readily switch providers, businesses may face pressure to reduce prices when costs decline. Where alternatives are limited, or customers have little bargaining power, reductions may be slower or less complete.
Determining which situation applies in Uganda requires more than comparing fuel prices with inflation. It means tracking what happens to actual taxi and bus fares, the cost of moving produce, wholesale and retail food prices, and the prices of selected manufactured goods as fuel prices change.
Transport operators, traders and economists can help establish which costs have remained elevated, how long adjustments normally take and whether competition is strong enough to pass savings on to customers. Such evidence would help distinguish genuine cost pressures from cases where businesses have little incentive to reduce prices.
That matters because households experience the cost of living through the total amount they spend, not through the inflation rate announced each month. A family may benefit from inflation slowing, but it will feel a more immediate improvement if the cost of transport, food and other essential purchases actually declines.
Uganda’s current fuel shock may eventually ease. The international oil market may stabilise, the exchange rate may improve and suppliers may replace expensive stocks with cheaper purchases. Whether those developments translate into meaningful relief for consumers will depend on how businesses adjust their prices and how competitive the markets they operate in are.
The central test is not simply whether petrol becomes cheaper. It is whether the savings travel beyond the pump. For households, that is the difference between a fuel-price correction and a genuine easing of the cost of living.
