Tanzania's fuel prices jumped sharply in April 2026. Petrol is up 33%, diesel is up 33%, and kerosene is up 26% compared to March. The increases follow a global oil supply disruption caused by the conflict in the Middle East. Every trader who moves goods, runs a generator, or sells cooked food is already feeling the impact.

What Changed This Month

Tanzania's Energy and Water Utilities Regulatory Authority (EWURA) sets official fuel price caps each month. For April 2026, the new caps are significantly higher than March.

Fuel Type	March 2026 (per litre)	April 2026 (per litre)	Change
Petrol	Sh2,864	Sh3,820	+33%
Diesel	Sh2,858	Sh3,806	+33%
Kerosene	Sh2,932	Sh3,684	+26%

These are the new maximum prices at the pump. In practice, many stations were already charging close to these figures before the official announcement, as some retailers reportedly hoarded fuel ahead of the price revision.

Why Fuel Prices Jumped

The root cause is a major disruption to global oil supply. On February 28, 2026, military strikes on Iranian oil infrastructure — including fields, storage facilities, and refineries — were followed by Iran closing the Strait of Hormuz. That strait handles about 20% of global oil shipments. When it shut, crude oil prices spiked worldwide.

Tanzania imports most of its fuel from the Middle East. The disruption created two cost pressures at once: higher crude oil prices, and higher shipping and insurance costs for tankers taking longer alternative routes. Both get passed directly to the pump price.

This is not a local policy decision. EWURA raised the caps because the underlying cost of importing fuel went up sharply.

What It Costs Your Business

Transport and delivery

Diesel powers trucks, buses, and boda bodas. A 33% rise in diesel means any supplier delivering goods to your shop will face higher running costs. Most will pass those costs on. The Tanzania Transporters Association has warned publicly that fares and freight rates will rise. If you receive stock by road, your cost per delivery will go up.

Food and produce prices

Farmers use diesel for irrigation pumps and tractors. Distributors use it to move produce from farms to markets. Every step of the food supply chain runs on diesel. Higher diesel means higher food costs at the wholesale level. If you sell food, fresh produce, or groceries, expect your buying price to increase within weeks.

Kerosene and cooking fuel

For food vendors, street cooks, and market stalls using kerosene stoves, the 26% price increase is direct. A vendor cooking chapati, mandazi, or grilled meat absorbs that increase either through lower profit per item or by raising the selling price to customers.

Generator costs

Shops and traders who use petrol or diesel generators to handle power cuts will see their electricity costs rise in line with fuel prices. A 33% diesel increase translates to a 33% increase in the cost of every hour the generator runs.

"The surge in diesel prices will inevitably lead to higher public transport fares and increased distribution costs for goods, which will quickly translate into higher food prices at the market." — IPP Media / The Guardian Tanzania, April 2, 2026

What the Government Is Doing

President Samia Suluhu Hassan addressed the situation directly. She warned traders not to use the fuel price increase as an excuse to raise the prices of goods that were purchased before the hike. Stocks bought at the old prices should still be sold at prices reflecting those old costs, she said.

On April 9, Tanzania also implemented fuel consumption curbs, according to reporting by Automotive Transportation News, in an effort to reduce demand pressure on national fuel supplies.

The government has also warned that hoarding fuel to create artificial shortages is treated as economic sabotage — a serious criminal offence under Tanzanian law.

How to Protect Your Margins

Talk to your suppliers now. Ask whether their delivery costs have already changed. Lock in existing prices for any orders you can place before they revise their rates.
Audit what you spend on transport. If you collect stock yourself, calculate how much more each trip now costs. Factor that into your pricing.
Adjust prices in small steps. A sudden large price jump can push customers away. Small, gradual adjustments are easier for customers to absorb — and easier for you to explain.
Reduce your generator hours. Run the generator only for essential operations. LED lighting and phone banking for payments can reduce how much power you actually need.
Keep records. If a supplier raises prices, ask for a written invoice showing the new rate. This protects you if customers question your own price changes.

Why This Matters

Fuel is one of the hidden costs that runs through almost everything a small business does. You may not sell petrol or diesel, but those products are in your supply chain whether you see them or not. A 33% increase does not stay in the fuel sector. It moves into transport rates, food prices, import costs, and delivery fees — often within weeks. Tanzanian traders who understand this can adjust their buying, pricing, and operations ahead of the full impact reaching their shelves.

Conclusion

Tanzania's April 2026 fuel price increases are among the steepest in recent memory, driven by a global supply disruption beyond the country's control. The knock-on effects for shop owners, food vendors, and market traders are real and will compound over the coming weeks. Review your costs now, talk to your suppliers, and adjust incrementally before the full pressure hits your margins.
