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.

  • 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 underwriters
Oil markets / Lloyd's underwriters
Futures markets priced CENTCOM's strikes-complete statement as a de-escalation signal and pushed Brent down 1.7 per cent to $94.71, even as the IRGC declared Hormuz closed. Lloyd's war-risk premiums held elevated because institutional de-listing requires a UN Security Council resolution that Russia and China have just shown they will block.
Pakistan (mediator)
Pakistan (mediator)
Interior minister Mohsin Naqvi carried dual civilian and military letters to Mojtaba Khamenei in Tehran on 6-7 June with no public response. The IRGC's Hormuz closure on 11 June shows the corps is acting independently of the channel Pakistan is using, making the mediation structurally unable to produce a binding commitment without direct IRGC access.
Russia and China
Russia and China
Russia and China voted against GOV/2026/40 at the IAEA Board, following through on the blocking position coordinated with Grossi in Geneva on 5 June; both states continue to oppose Western institutional pressure on Iran at every multilateral venue.

E3 and IAEA (UK, France, Germany)
The E3 co-sponsored IAEA resolution GOV/2026/40, adopted 21-3-10 on 10 June, demanding Iran disclose 440.9 kg of unaccounted HEU and admit inspectors to four denied facilities. The 10 abstentions and Russia-China noes leave any Security Council referral without a viable enforcement path.
IRGC / Iran military command
IRGC / Iran military command
The corps declared Hormuz closed to all traffic on 11 June and claimed two vessels struck, overriding the MoU its own civilian negotiators were pursuing through Pakistan. The closure order used the Persian Gulf Strait Authority apparatus to convert a toll mechanism into a military prohibition.
Trump administration / CENTCOM
Trump administration / CENTCOM
CENTCOM completed a second day of strikes on Tehran, Sirik and Minab, rejected the IRGC Hormuz closure as inconsistent with observed transit, and said strikes were complete. Hegseth framed the bombing explicitly as the negotiation: the method is coercive deal-making with no stated pause threshold.
