Strait of Hormuz Crisis: What Impact for Mauritius?

Mauritius is a small, open economy that depends heavily on international trade, with roughly USD 6.65 billion of imports in 2024. Food, fuel and equipment all arrive by sea. So as the Strait of Hormuz crisis escalates, what is the real impact for the island and its residents? This analysis cuts through the headlines, sector by sector, with a simple conclusion up front: the risk is higher prices, not empty shelves.

The situation: a chokepoint under pressure

The Strait of Hormuz, through which around 20% of the world's oil passes, has effectively seized up. Daily traffic has collapsed from about 138 vessels a day to a handful, and tankers have stopped transiting. Dozens of ships are anchored nearby, some have been attacked, and insurers have pulled war-risk cover, which freezes commercial traffic in practice. The International Energy Agency describes the strait as the world's single most important oil transit chokepoint.

Kuwait has halted production, Iraq has cut output by about 70%, and Qatar has warned that crude could reach USD 150. This is a worldwide shock to energy markets, not a Mauritius-specific event, which is the most important context to keep in mind throughout.

Oil: direct exposure, but no shortage in sight

In 2024, Mauritius imported roughly USD 1.4 billion of petroleum products. Because the island has no oil, gas or coal of its own, around 82% of its primary energy is imported. Here is how its fuel suppliers break down:

In plain terms: about half of the oil Mauritius imports travels on a route now under threat. The other half moves on shipping lanes that are entirely clear of the Gulf.

1. India: the immediate Plan B, and a strong one

India already supplies USD 202 million of refined fuel to Mauritius. Its refineries, including Jamnagar (the largest in the world, at 1.4 million barrels a day), sit on India's west coast and have no dependence on the Strait of Hormuz. The State Trading Corporation (STC), Mauritius's sole authorized importer of petroleum products, already runs a multi-year contract with an Indian refiner only about eight days' sailing away.

The India-to-Mauritius sea route (7 to 10 days) crosses the open Indian Ocean, far from the conflict zone. The capacity is there, the route is safe, and Indian Oil already operates on Mauritian soil, so redirecting purchases toward Indian refineries is a realistic lever rather than a theoretical one.

2. Coal for electricity: minimal risk

Roughly 30% of Mauritius's primary energy comes from South African coal (Richards Bay) and about 10% from local renewables. That means a meaningful slice of the country's electricity is generated without oil and entirely outside the threat zone. Coal arrives directly from Richards Bay on a 5-to-8-day voyage.

3. Buffer stocks exist

Mauritius holds an estimated two to four weeks of fuel reserves in the tank farms of Port Louis. Even in a scenario where suppliers have to be switched, there is no risk of an abrupt cut-off, only the need to manage a transition.

4. A fully closed Hormuz: unsustainable worldwide

A fifth of the world's oil moves through this strait, so a prolonged closure is a shock to the entire planet, not to Mauritius specifically. The international pressure to reopen a shipping corridor would be enormous. Even during the Iran-Iraq War (1980-1988), Hormuz was never closed for long.

Food: no supplier transits Hormuz

Mauritius has an overall food self-sufficiency ratio of only about 25%: it imports three-quarters of what it eats, worth roughly USD 1.1 billion in 2024. But the categories are not equal, and where the food comes from matters more than the headline number.

What Mauritius grows locally

• Fresh vegetables: close to 100% self-sufficient. Imports are limited to onions, potatoes and garlic. For everyday vegetables (tomatoes, squash, beans, salads) the island feeds itself
• Tropical fruit: close to 100% self-sufficient. The USD 51M of imports covers temperate fruit (apples, grapes, oranges), while mangoes, lychees, bananas and pineapples are grown locally
• Poultry: about 99% self-sufficient. Mauritius produces almost all of its own chicken, though roughly 90% of the animal feed (corn, soy) is imported from Argentina on a clear route

What Mauritius has to import

Mauritius's food shipping routes

• India: direct across the Indian Ocean, 7 to 10 days at sea
• South Africa: direct route, 5 to 8 days (the shortest)
• Australia: direct across the Indian Ocean, 8 to 12 days
• New Zealand: South Pacific then Indian Ocean, 12 to 18 days
• France / Spain: via Suez or the Cape of Good Hope, 20 to 35 days
• Argentina / Brazil: South Atlantic then the Cape then the Indian Ocean, 25 to 35 days

The real impact: prices, not availability

The risk for Mauritius is not scarcity but inflation. UN Trade and Development (UNCTAD) has flagged exactly this pattern for import-dependent economies: higher energy, freight and insurance costs feed through into the shelf price. Here are the mechanisms at work:

• Shipping costs: oil above USD 100 pushes freight rates up. Fuel is 40 to 60% of the cost of a cargo voyage
• Marine insurance: premiums rise globally during conflict, even on routes that are not directly affected
• Knock-on effect on food: if the conflict drags on, world food prices climb because energy drags the whole cost base upward

For residents and expats in Mauritius, this means a likely rise in the cost of living in the short term, mostly on fuel and imported goods. But no shortage is on the cards. If you are weighing a move, our guide on why people move to Mauritius looks at the fundamentals that a price wobble does not change.

"Mauritius will see prices rise like the rest of the world. But unlike many small islands, its food suppliers sit 100% outside the conflict zone, and credible alternatives exist for oil."
