Sri Lanka fuel supply restrictions deepen as private operators report heavy diesel losses, renewing scrutiny of pricing and fuel quality controls.
COLOMBO — Restrictions on diesel supplies by three of Sri Lanka’s private fuel distributors have exposed growing strains in the country’s petroleum pricing system, while also renewing attention on the safeguards used to ensure imported fuel continues to meet required quality standards.
Lanka IOC, Sinopec and RM Parks have reduced diesel deliveries to parts of their dealer networks as rapidly rising international oil prices squeeze margins under Sri Lanka’s domestic pricing arrangements. Industry representatives say hundreds of filling stations have been affected.
The immediate problem is financial rather than technical. Information submitted to the Ministry of Energy indicates that Lanka IOC has reported a loss of about Rs. 141 per litre of diesel, RM Parks about Rs. 160 and Sinopec about Rs. 163 under current market conditions. Private suppliers have consequently sought government intervention or a revision of the pricing arrangement.
The supply restrictions come as international oil markets remain under severe pressure. Brent crude settled at US$104.87 a barrel on September 18 after remaining above US$100 as conflict and disruptions affecting Middle Eastern energy and shipping routes unsettled global markets.
Hundreds of private filling stations affected
The Fuel Distributors Association has said all three private suppliers have limited diesel releases to their dealer networks, although the Ceylon Petroleum Corporation maintains that there is no nationwide diesel shortage.
Separate reports citing the Filling Station Owners’ Association said distribution had been restricted at around 500 stations, including approximately 250 Lanka IOC outlets, 150 Sinopec stations and 100 RM Parks stations.
The precise scale has varied as the dispute has continued. Later reports suggested restrictions were affecting 275 Lanka IOC stations alongside 150 Sinopec and 100 RM Parks outlets, with private-sector diesel distribution estimated to have fallen substantially.
The dispute highlights a structural difficulty in Sri Lanka’s partially liberalised petroleum market. Private companies import finished petroleum products but operate in a market where domestic retail prices are heavily influenced by government pricing policy.
According to the private suppliers, large differences between international acquisition costs and local selling prices have made diesel sales commercially difficult. The Government previously provided subsidies when international prices rose sharply, including support for diesel and petrol during April and May, but that arrangement was later discontinued.
Energy Minister Anura Karunathilaka has said several responses are being considered, including renewed subsidies, adjustments to retail prices or the introduction of upper and lower price bands that would give individual suppliers greater pricing flexibility. A decision could be taken before the end of September.
Supply pressure brings fuel quality back into focus
The commercial dispute has also raised a separate question: whether Sri Lanka’s fuel-quality surveillance system is strong enough to withstand periods of severe international price pressure.
There is currently no evidence that Lanka IOC, Sinopec or RM Parks has imported, or intends to import, fuel below Sri Lanka’s required specifications.
Nor does a reduction in a company’s commercial margin establish that it would seek lower-quality supplies.
However, periods of exceptional international price volatility make independent product testing particularly important because refined petroleum products vary in composition and specification, while modern vehicle systems can be sensitive to fuel contamination or fuel that does not conform to the manufacturer’s requirements.
The distinction is important. The risk requiring regulatory attention is not simply whether a consignment is less expensive, but whether every shipment continues to comply fully with applicable specifications before it reaches consumers.
The Sri Lanka Standards Institution maintains standards and testing methods covering petroleum characteristics, including measurement of total sulphur content in engine fuels.
Fuel containing excessive sulphur or contaminants can adversely affect emissions-control equipment and other components, particularly in modern vehicles equipped with sophisticated injection and after-treatment systems. That makes consistent testing and enforcement critical regardless of whether fuel is supplied by the state or private companies.
Suggestions that motorists may eventually require a specialised form of “fuel contamination insurance” should therefore be understood as a warning about potential consumer exposure rather than an existing insurance requirement.
Ordinary motor insurance policies may differ significantly in their treatment of internal mechanical damage, contaminated fuel and consequential engine failures, making prevention through effective fuel-quality control preferable to disputes after damage occurs.
CPSTL laboratories play key quality-control role
Sri Lanka already has infrastructure for petroleum-product testing.
Ceylon Petroleum Storage Terminals Limited says its main laboratory at Kolonnawa performs independent quality-assurance work for marketing companies and tests every batch of receipts, product transfers and bulk delivery tanks before release against relevant specifications.
At the Muthurajawela terminal, laboratory personnel and independent surveyors are also involved in sampling imported products from vessels before distribution.
Maintaining the operational independence and technical capacity of these laboratories is therefore particularly important during periods of intense commercial pressure.
A stronger surveillance regime could include more frequent random sampling throughout the distribution chain, transparent reporting of failed samples and clear procedures for tracing contaminated or non-compliant products to their source.
Any expansion of regulatory powers would, however, have to reflect Sri Lanka’s existing legal framework. The Public Utilities Commission of Sri Lanka is the designated regulator for the petroleum sector but states that legislation giving it full regulatory authority over the downstream petroleum industry has yet to be enacted.
Consequently, proposals to give the PUCSL mandatory filling-station-level testing or enforcement powers would require an appropriate legal and regulatory basis rather than simply an administrative instruction.
Sapugaskanda gives CPC a different cost structure
The current dispute has also highlighted the importance, and limitations, of the Sapugaskanda refinery.
Unlike the three private suppliers, CPC operates a domestic refinery as well as importing finished petroleum products.
CPC Chairman D.J. Rajakaruna has said refinery earnings have helped the corporation offset part of the losses arising from diesel sales, giving CPC a financial mechanism that companies dependent on imported finished products do not have.
Sapugaskanda was commissioned in 1969 to process approximately 38,000 barrels per day and was originally designed around Iranian light crude and similar grades. CPC says crude oils with comparable characteristics, including Upper Zakum and Arabian Light, can be processed at the facility while meeting required specifications.
Murban crude from the United Arab Emirates has also been extensively processed at Sapugaskanda. CPC’s 2022 annual reporting shows that Murban accounted for 53.5% of crude processed that year, alongside Urals, Siberian Light and ESPO crude.
This also clarifies one recurring misconception: Murban is a UAE crude grade, not an Iranian product.
The refinery nevertheless has technical and economic limitations. Government and CPC reports have repeatedly identified the need for modernisation, while the facility currently supplies only part of Sri Lanka’s overall petroleum requirement.
That means Sapugaskanda can strengthen national supply resilience, but it cannot by itself eliminate Sri Lanka’s dependence on imported refined products.
Government weighs pricing options
Karunathilaka has said the Government recognises the concerns raised by private distributors while maintaining that consumer interests and competition must also be protected.
Officials have held discussions with the companies, and the Minister has indicated that subsidies, price revisions or a pricing band are among the options under consideration.
Private operators have also agreed to continue uninterrupted diesel supplies to 52 areas without CPC filling stations, according to the Ministry.
The present dispute therefore involves two separate but connected challenges.
The first is economic: how Sri Lanka maintains a competitive fuel market when international prices rise sharply above assumptions built into domestic retail prices.
The second is regulatory: how authorities guarantee that every litre entering the market meets the required specifications regardless of commercial pressure, supplier or country of origin.
Resolving the immediate distribution restrictions may require changes to pricing or financial arrangements. Protecting motorists over the longer term will require something more permanent: independent testing, transparent enforcement and a regulatory structure capable of ensuring that competition never comes at the expense of fuel standards.
For consumers, energy security is ultimately not measured only by whether fuel is available at the pump. It also depends on whether the product going into the tank consistently meets the standards on which modern engines, transport operators and the wider economy depend.
