Oil prices fall as Russian diesel supply prospects offset gulf disruption fears

Oil prices fell on Tuesday, October 13, as traders weighed the prospect of additional Russian diesel supplies against renewed threats to energy infrastructure and shipping routes in the Middle East, leaving crude benchmarks on course for their first decline in nearly a week.

Brent crude futures dropped $1.30, or 1.2%, to $105.35 a barrel by 0329 GMT, while US West Texas Intermediate (WTI) crude futures fell $1.25, or 1.3%, to $92.49 a barrel.

The decline followed gains of nearly $2 a barrel in the previous session, when Brent settled at its highest level since September 15.

The latest pullback suggests that expectations of additional fuel supplies are offering some relief, although persistent geopolitical tensions continue to support prices.

US President Donald Trump said Russia had agreed to supply diesel to global markets. His administration also temporarily lifted US sanctions on Russian fuel, a move intended to facilitate additional supplies amid tight global fuel markets.
The prospect of more Russian diesel could ease pressure on refiners and consumers, particularly in markets facing shortages of middle distillates used in road transport, industry and other economic activities.

However, the scale and timing of any additional deliveries remain important to determining whether the move will have a lasting effect on prices.

There is also uncertainty over the durability of a proposed energy ceasefire between Russia and Ukraine.

ING analysts said there was considerable scepticism about the arrangement, particularly following reports that Russia had continued striking Ukrainian energy targets after the ceasefire announcement.

The agreement has also attracted criticism from lawmakers in both major US political parties, who argue that easing restrictions on Russian energy could conflict with legislation designed to deprive Moscow of revenue for its war in Ukraine.
While the prospect of increased Russian diesel exports weighed on prices, fresh security concerns in the Middle East continued to limit the market’s downside.

Iran-aligned Houthi forces struck Riyadh’s international airport over the weekend, raising concerns about the vulnerability of Saudi infrastructure.

Attacks on tankers near the Strait of Hormuz have added to fears that further incidents could disrupt crude and refined-product shipments.

The Strait of Hormuz is a critical energy transit route connecting Gulf producers with international markets.

Any prolonged disruption could delay cargoes, increase freight costs and tighten supplies, particularly for economies heavily dependent on energy imports.
The latest incidents have also threatened to undermine the recovery in Middle Eastern oil supplies recorded in September.

Traders are therefore balancing the potential benefit of additional Russian fuel against the possibility of fresh interruptions to Gulf production and exports.

“Fresh diesel supply from Russia and steadier Saudi flows are offering some relief, yet the market still looks more worried about the risk of further hits to ships or pipelines in the Gulf than it is reassured by extra barrels,” said Tim Waterer, chief analyst at KCM Trade.

He added that prices could remain biased to the upside until there are clearer signs of de-escalation.

The cost of transporting energy has become another source of pressure. Ministers from OPEC and non-OPEC countries participating in the Declaration of Cooperation said shipping and insurance costs had climbed to more than one-third of the value of the commodity in some cases, impeding the efficient movement of crude oil and petroleum products.

Such increases can keep delivered fuel prices elevated even when benchmark crude prices retreat. Higher freight and insurance costs also feed into the operating expenses of traders, refiners and importers, potentially passing through to consumers.

The price outlook is also being shaped by a weaker demand forecast. OPEC Secretary-General Haitham Al Ghais said on Monday that the organisation had reduced its forecast for global oil demand growth in 2026 to 400,000 barrels per day, from 1.4 million bpd projected at the beginning of the year.
The revision reflects developments in the market over the course of 2026 and suggests that consumption growth has been considerably weaker than previously anticipated. OPEC expects some demand deferred this year to materialise in 2027.

The lower forecast would ordinarily weigh on crude prices by pointing to slower growth in consumption.

However, the immediate impact has been offset by supply-side risks, as traders remain concerned that attacks on energy infrastructure and shipping could restrict the volume of oil and fuel reaching international markets.

The combination of weaker demand expectations and persistent supply threats leaves the market highly sensitive to developments in Russia, Ukraine and the Gulf.

For oil-importing economies, including Nigeria, the direction of crude and refined-product prices matters for domestic fuel costs, inflation and foreign-exchange demand.
A sustained decline in global prices could ease import costs and inflationary pressure, although the benefit would depend on exchange-rate movements, freight charges, refining economics and domestic pricing arrangements.

For Nigeria, a major crude producer that also relies on imported petroleum products and domestic refining capacity, higher crude prices can support export earnings and government revenue.

But gains are not automatic: production levels, operational costs, the volume of crude available for export and the cost of refined products all influence the net effect on the economy.

With Brent still trading above $105 a barrel, Tuesday’s decline represents a retreat from recent highs rather than clear evidence that the market’s supply concerns have eased.

Traders are likely to remain focused on the implementation of the Russian diesel arrangement, the security of Gulf shipping lanes and any further changes to OPEC’s demand outlook.
