Executive Summary
One of the largest drone attacks yet directed towards Moscow has struck an oil refinery in the Russian capital, raising further concerns over already constrained Russian fuel production.
Russian authorities said more than 1,600 drones had been intercepted since Saturday, including approximately 450 heading towards Moscow.
Several drones nevertheless reached the Moscow refinery.
Reuters witnesses heard explosions and saw smoke rising from the facility.
The extent of damage to the refinery was not immediately known.
Two people were killed elsewhere in the Moscow region and hundreds were evacuated from a residential building following drone impacts.
Ukraine had not commented on the attacks at the time of reporting.
The development is particularly significant because Russia and Ukraine have continued attacking energy infrastructure despite President Donald Trump’s announcement earlier this week that the two countries had agreed to stop.
Previous Ukrainian attacks have already removed significant Russian refining capacity and contributed to:
- Fuel shortages.
- Higher domestic prices.
- Export restrictions.
- Reduced diesel availability.
The important development is therefore not simply another refinery attack, but evidence that the expected reduction in energy-infrastructure risk has not yet materialised.
UK Impact
The UK no longer relies directly upon Russian refined fuel in the way it did before sanctions.
But diesel and other refined products trade through international markets.
Reduced Russian output can therefore increase competition for alternative supplies.
UK businesses may experience the effect through:
- Road haulage.
- Agricultural costs.
- Construction.
- Industrial machinery.
- Backup generation.
- Freight surcharges.
- Supplier margins.
The risk is particularly relevant because Middle Eastern refined-product supply is simultaneously under pressure.
Global Impact
The Moscow refinery processed approximately 11.6 million tonnes of crude in 2024.
Its output included approximately:
- 2.9 million tonnes of gasoline.
- 3.2 million tonnes of diesel.
The plant has been targeted previously.
The latest attack therefore arrives when Russia’s refining network is already operating under sustained pressure.
This matters internationally because Russia has historically been one of the world’s major exporters of diesel and other refined products.
Losses of Russian capacity can force traditional customers to compete for replacement fuel from other markets.
Our View
Businesses should avoid assuming that diplomatic announcements immediately remove operational risk.
Companies should ask:
- How dependent are logistics costs upon diesel?
- Are haulage contracts fuel-indexed?
- Can carriers impose emergency surcharges?
- Are agricultural suppliers fuel-intensive?
- Are construction projects exposed?
- Are backup generators dependent upon diesel?
- Is emergency fuel stored appropriately?
- Are alternative suppliers available?
- Could Russian export restrictions tighten further?
- Could Middle Eastern disruption compound the shortage?
- Are customer prices fixed?
- Can increased transport costs be passed through?
- Could suppliers experience margin pressure?
- Are fuel-price assumptions within budgets still realistic?
- Are critical suppliers financially resilient?
There is also an important lesson around ceasefires and negotiated arrangements.
Businesses should distinguish between an announced agreement and an observable change in operational conditions.
Until attacks actually stop and damaged capacity returns, supply-chain planning should be based upon what is happening physically rather than what has been announced diplomatically.
