The State Trading Corporation was established by Act of Parliament on 24 October 1982 to regulate and rationalise trade in essential commodities. It became operational in January 1983. According to its own institutional description, confirmed on its official website, the STC is "solely responsible for the importation and supply of Petroleum Products to meet the country's inland requirements," covering fuel for public transport, industrial and commercial activities, private motor vehicles, the operation of turbines by the Central Electricity Board to generate electricity, and aircraft refuelling at SSR International Airport. The STC's total annual imports of petroleum products have exceeded 1.1 million metric tons. All its selling prices are fixed by the government. The STC operates its domestic lines of business strictly on a cost basis with no profit mark-up. This is the foundation of the mechanism: a state entity with monopoly import rights, selling at prices set by government decree, with the fiscal consequence of any gap between cost and price absorbed by the state.

The Petroleum Pricing Committee is established under Government Notice and is responsible for determining retail fuel prices. According to its own press release of 14 August 2026, the PPC met to assess retail prices in accordance with Regulation 8 of the Consumer Protection (Control of Price of Petroleum Products) Regulations 2011, as amended. The committee reviewed the evolution of world prices and assessed the estimated deficit of Rs 3.50 billion in the Price Stabilisation Account before recommending the Mogas price increase. The Price Stabilisation Account is the mechanism by which the gap between world prices and administered retail prices is tracked and eventually reconciled. When world prices rise faster than the PPC raises retail prices, the PSA accumulates a deficit. That deficit represents the cumulative amount by which consumers were charged below the landed cost of fuel. The Rs 3.50 billion figure is the accumulated deferred cost as of 14 August 2026.

The STC's own FAQ documentation states that taxes, levies, and contributions including subsidies on staple food and LPG represent 40 to 55 per cent of the retail price at which consumers buy petrol and diesel. The same documentation records that subsidies on ration rice, wheat flour, and LPG cost the STC more than Rs 1.2 billion, a figure from the 2019/20 period when the annual report recorded a deficit of MUR 917.2 million attributable to subsidy payments. The subsidy architecture therefore operates on two levels simultaneously: the administered retail price is held below world cost (creating the PSA deficit), and a portion of the taxes embedded in the retail price cross-subsidises food and LPG for the population. The fiscal cost flows in both directions: from the public budget to the STC when the PSA deficit is settled, and from fuel consumers to food and LPG subsidy recipients through the embedded levy structure.

When petroleum products arrive at Port Louis, they are discharged through pipelines into the shore tanks of four Local Oil Companies and the Central Electricity Board, all located within the port area. The four LOCs are the retail distribution entities: they purchase from the STC at government-fixed prices and sell to filling stations and direct commercial customers at government-fixed margins. The CEB purchases fuel directly from STC to run its thermal generation turbines, which according to the US Department of Commerce Country Commercial Guide for Mauritius produce approximately 47 per cent of the country's electricity. The remaining 53 per cent comes from Independent Power Producers, which also rely substantially on imported fossil fuels outside the sugarcane harvesting season. The electricity that Mauritian commercial and industrial entities consume is therefore substantially generated from petroleum products and coal imported at world market prices, sold to the CEB and IPPs at government-administered or market-negotiated rates, and priced to end consumers through the CEB tariff structure. When the STC holds fuel prices below cost, the CEB's input cost is also affected, as a portion of its fuel is sourced through the STC at administered prices.

The administered pricing mechanism is designed to protect the population from world market volatility. It achieves this by holding retail prices below landed cost when markets spike, with the PSA deficit recording the accumulated gap. The protection is available to all consumers: the household, the small business, the large commercial operation, and the industrial entity. The mechanism does not discriminate by consumer category. It is therefore neutral in its design and asymmetric in its effect.

The asymmetry arises from the relationship between the value of below-cost pricing and the volume of consumption. A household that purchases thirty litres of petrol per month captures approximately Rs 190 of below-cost benefit when the administered price is held Rs 6.40 per litre below the market-justified level, the gap implied by the Mogas adjustment of 14 August 2026. A commercial logistics operation, a hotel complex, a food distribution network, or an industrial facility that consumes 30,000 litres per month captures Rs 192,000 of the same benefit per month. The mechanism is identical for both. The value captured is proportional to the volume consumed. The entities that consume at the greatest volume capture the greatest absolute value from the subsidy. The public budget absorbs the cost for all of them equally.

The conglomerate sector of Mauritius, as disclosed on the Stock Exchange of Mauritius, is the segment of the economy that operates at the consumption scale where administered pricing delivers material fiscal benefit. The major listed conglomerates, IBL Group (Ireland Blyth Limited), Rogers Group, CIEL Group, ENL Group, and Harel Mallac, operate collectively across logistics and distribution networks, hotel and hospitality complexes, food manufacturing and retail chains, agricultural operations, and industrial facilities. These operations are large consumers of diesel fuel, industrial fuel oil, and electricity. They are not exceptional consumers in any pejorative sense: their consumption is proportional to their industrial and commercial scale, which is substantial. IBL Group, for example, encompasses among its disclosed portfolio: logistics and port operations, food manufacturing and distribution, healthcare infrastructure, and retail chains. Each of these verticals requires significant fuel and electricity inputs at commercial volume.

The structural point is precise and limited. When the Price Stabilisation Account accumulates a deficit of Rs 3.50 billion because retail fuel prices have been held below cost, that deficit represents a transfer of value from the public budget to all fuel consumers in proportion to their consumption. The household that filled its tank receives a small share of that transfer. The conglomerate operating a distribution fleet, a hotel complex, and a manufacturing facility receives a large share of the same transfer. Neither is acting improperly. The mechanism delivers what it is designed to deliver: below-cost fuel to all consumers. The structural consequence, that the entities with the greatest consumption capacity capture the greatest absolute value from the subsidy, is not a design flaw. It is the arithmetic of a universal price support applied to a market with highly unequal consumption volumes.
