Scroll through the local press this month and you could be forgiven for bracing yourself at the pump. Headlines have warned of another maximum increase, with talk of the litre going well beyond Rs 75. Then, this week, oil prices dipped on news of talks between the United States and Iran.

So which is it? A fresh shock, or relief on the way? The honest answer sits somewhere in between, and it matters for how you plan your motoring budget.

A Rise of Up to 10 Per Cent Is on the Cards

The pressure behind the headlines is genuine. As of 21 September, the official pricing formula showed a gap of 9.94 per cent for petrol and 10.86 per cent for diesel.

If the Petroleum Pricing Committee met on that basis, petrol would go from Rs 70.65 to Rs 77.70 a litre. Diesel, held at the regulatory 10 per cent cap, would move from Rs 71.25 to around Rs 78.35.

Meanwhile, holding prices where they are is costing money. The Price Stabilisation Account, the fund meant to cushion motorists from global swings, is sitting at a deficit of Rs 3.32 billion. The country's oil import bill had already reached Rs 57.3 billion in the first seven months of the year.

For a typical 40-litre petrol tank, a maximum rise would add roughly Rs 282 to every fill-up. A 50-litre diesel tank would cost around Rs 355 more. The Minister of Commerce has said the committee will meet when it judges it necessary, so the timing remains open.

What the Oil Dip Actually Changes

Now the better news. On Wednesday, Brent crude traded at $98.41 a barrel after President Trump described a three-hour meeting involving US and Iranian delegations as "very productive", with another meeting already planned. Prices had fallen for several sessions in a row.

That is welcome, but keep it in perspective. Brent has repeatedly gone above $100 since the Middle East conflict began in February and remains up sharply on where it started the year. The Strait of Hormuz is still heavily disrupted, the US blockade of Iranian ports continues, and shipping through the Red Sea remains at risk.

There is also a detail that matters for Mauritius in particular. We pay for refined fuel, not crude. Even as crude has eased, concerns over refined products, and diesel especially, have kept growing.

Why a Price Cut Isn't Coming Soon

Supply, at least, isn't the worry. A cargo of almost 40,000 tonnes arrived from India on 23 September, though the Ministry of Commerce has been clear that new deliveries don't in themselves change the retail price.

Even if oil keeps falling, do not expect cheaper fuel at the pump in the near term. The regulations only allow a price reduction when there are funds available in the Price Stabilisation Account. With a deficit of more than Rs 3 billion, any saving from lower oil prices will go towards rebuilding that fund first.

Reference prices are also averaged over previous months and forecasts, so today's dip feeds through slowly. The realistic best case is a smaller increase, or no increase at all, rather than a cut.

What You Can Control

Fuel prices will keep moving with events thousands of kilometres away. How much fuel you use is another matter. Smooth, patient driving at the speed limit is safer and noticeably cheaper to run, and a modern hybrid or electric vehicle takes much of the sting out of every revision.

If your next car is on your mind, compare hybrids, EVs and efficient petrol models onAutoCloud.mu. The next revision is a matter of when, not if. The question is whether your next car will make it matter a little less.
