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.

Jordan

Jordan's armed forces downed three Iranian missiles on Tuesday with no casualties, a second successful interception since the 19 July strike on Muwaffaq Salti that killed three US service members. Amman has neither confirmed nor denied ISW's assessment that its intelligence sharing is a Russia-China cover story.
Operation Aspides
Operation Aspides
Operation Aspides has not needed to intervene against the Houthi Bab al-Mandab embargo: six vessels, including the Chinese VLCC Xin Long Yang, reversed course after radio hailing alone, with no vessel boarded, fired on or stopped by force.

Hegseth told the Senate Appropriations Committee the campaign has cost $37.5 billion so far, without saying whether the figure is obligated, appropriated or incremental. It is the first cost Washington has put on the war, arriving as OMB seeks $87.6 billion for the wider supplemental.

Iran's IRGC and Artesh reported destroying radar and Patriot installations at four Gulf bases on Tuesday night, the fifth dated iteration of the same claim against the same sites since 13 July. Neither Kuwait nor Bahrain has named or confirmed a single base as destroyed.
Saudi Arabia
Saudi Arabia
Riyadh has pressed Washington to end the Hormuz blockade specifically to remove Tehran's incentive for the Houthis to escalate Bab al-Mandab beyond radio warnings. It treats the embargo as coordinated pressure on Saudi shipping tied to the Hormuz campaign, not an independent Yemeni action.

Kuwait reported power and desalination stations struck for a fourth consecutive day and four cruise missiles plus 21 drones intercepted since dawn Wednesday, while its defence ministry statement used only the word interception, never destruction. Kuwait has confirmed no Iranian claim of a destroyed base.
