Carnegie: Iran war masks Kyiv's oil strike cost

3 min read

Carnegie put numbers on a paradox this week: Ukrainian strikes cut Russian crude exports by 33% between 25 March and 11 April, yet post-attack weekly revenues ran 62% above late February because the Iran conflict drove global prices higher.

Key takeaway

Tehran's war is currently subsidising two thirds of Moscow's export revenue loss.

Analysts at the Carnegie Endowment for International Peace, a Washington-based non-partisan think tank, published a quantification in April showing that Ukrainian strikes cut Russian crude exports from 5.2 million to 3.5 million barrels per day between 25 March and 11 April, a 33% volume cut 1. Over the same period the Iran conflict drove global prices higher. Post-attack weekly revenues ran 17% below the preceding two weeks but 62% above late February. Carnegie's figures place the price offset above the volume loss on a common ledger for the first time.

Ukraine's oil strike campaign has been scaling since the Baltic terminal hits in late March, and Urals crude spiked through the Iran war's early-April phase . With Russian barrels displaced from the market and global demand elevated by Hormuz risk, the residual barrels Moscow sells clear at a premium that covers most of the shortfall. Tehran's war is functioning as Moscow's revenue insurance.

That subsidy is contingent. If the strait of Hormuz reopens and global prices fall, the fiscal squeeze Reshetnikov named in the same fortnight tightens directly. The UK-France planning conference at Northwood on 22 April is aimed at exactly that reopening, which means the same week's institutional calendar contains both the lever that keeps Russia's revenue high and the lever that would pull it down. Carnegie's quantification is the first analytical frame to price the link between the two theatres on a common ledger, and it positions Moscow's fiscal stability on an axis Moscow does not control at either end.

Deep Analysis

In plain English

Ukraine has been attacking Russia's oil export facilities: the ports, pipelines and tanks that Russia uses to sell oil abroad. That campaign cut Russia's oil exports by about a third between late March and mid-April. Normally that would hit Russia's income hard. But at the same time, a separate war between the US, Israel, and Iran drove global oil prices sharply higher, because Iran's threat to block the Strait of Hormuz: the narrow waterway through which 20% of global oil passes: made buyers nervous. Higher prices partially compensated Russia for selling less oil. It is an accidental subsidy from the Iran conflict to Russia's war chest.

What could happen next?
  • Risk

    A successful Hormuz reopening from the Northwood conference would depress Brent and Urals prices, removing the Iran-war price floor that currently offsets Ukraine's volume cut: tightening Russia's revenue position significantly without any new Ukrainian strike action required.

  • Opportunity

    Ukraine's energy strike campaign remains economically effective even when price offsets the volume impact: each destroyed refinery or dispatch station degrades domestic refined-product supply chains that cannot be offset by higher export prices, creating internal fuel shortages distinct from export revenue calculations.

    Medium term · 0.65
  • Risk

    Shadow fleet concentration on Russian National Reinsurance Company cover, driven by cumulative EU designations reaching 632 vessels, creates an unquantified tail risk: a single catastrophic tanker casualty could expose RNRC's capital inadequacy and trigger a fleet-wide insurance crisis.

Different Perspectives
Oil markets / Lloyd's of London
Oil markets / Lloyd's of London
Brent fell to near $87.33 on 80 per cent deal-probability pricing, but Lloyd's has not de-listed Hormuz from its war-risk register and shipping diversions continue at 139 vessels. Insurance markets are lagging futures: physical risk remains while financial markets have spent the good news before the paper exists.
India
India
Modi is expected to raise the deaths of three Indian sailors in the 11 June CENTCOM strike on the MT Settebello with Trump at G7 sidelines, the first non-party leader to put the blockade's human cost into a formal bilateral. New Delhi is also a major Iranian oil buyer whose import volumes the sanctions-relief terms will govern.
Israel (Netanyahu)
Israel (Netanyahu)
Netanyahu stated Israel is not party to the deal on 12 June; Defence Minister Katz ruled out the Lebanon withdrawal Iran's draft demands, inserting a third blocker the US-Iran negotiating channel cannot resolve. Israel's position tethers Hormuz reopening to a Lebanon settlement Washington has not brokered.
Pakistan (mediator, Sharif/Naqvi)
Pakistan (mediator, Sharif/Naqvi)
Sharif declared a final agreed text on 12 June before either principal confirmed it, running two Tehran visits in under a week without securing a written IRGC or Khamenei response. Islamabad's incentive to claim a diplomatic win outpaces its standing to deliver either capital's signature.
Iran foreign ministry (Araghchi)
Iran foreign ministry (Araghchi)
Araghchi declared digital signing within days while setting dilute-in-Iran as a non-negotiable red line on the 440.9 kg HEU stockpile, a standing Tehran position he cannot override without authorisation from Khamenei, reachable only by courier. The FM track is sprinting to close before the IRGC reasserts control.

Vance called the deal still TBD on 12 June while CENTCOM downed Iranian drones over Hormuz for a second consecutive night and the White House register stayed blank. Washington holds the ship-out position on HEU and has not signed an Iran instrument in over 100 days of conflict.
