France Estimates Iran War Cost at Up to €6 Billion as Borrowing Costs Surge
Published on Reflecto News | World News | Economy & Geopolitics
The economic fallout from the Iran war has cost France between €4 billion and €6 billion, Finance Minister Roland Lescure announced on Tuesday, as the government prepares new support measures alongside a freeze on some spending to mitigate the financial shock. The estimate, released as the fragile two-week ceasefire approaches its April 22 expiration, highlights the severe economic toll the conflict is taking on European economies .
“This crisis is still extremely uncertain in its course, in its economic impact and in its impact on public finances. At this stage, the potential impact of the crisis is still very large — we are talking about €4 billion to €6 billion.” — Roland Lescure, French Finance Minister
Surging Borrowing Costs: The Primary Driver
The sharp rise in government borrowing costs alone accounts for an additional €3.6 billion to France’s budget, Lescure told RTL radio . Since the outbreak of hostilities between the United States, Israel, and Iran on February 28, French bond yields have surged toward 17-year highs, dramatically increasing the cost of servicing the nation’s substantial debt .

|---|---|
| Total estimated loss | €4–6 billion |
| Higher borrowing costs (bond yields) | €3.6 billion |
| Energy support measures | Partially offset by spending freeze |

France, which already has one of the largest budget deficits in the euro zone, is particularly vulnerable to rising interest rates. The government has pledged to fully offset the budgetary impact of measures aimed at helping households cope with the energy price shock triggered by the conflict, but officials stress that support must be “strictly targeted at those most in need” .
Government Response: Spending Freeze, Not Budget Cuts
Prime Minister Sébastien Lecornu’s government is taking a two-pronged approach to the crisis:
1. Freezing Spending
The government plans to freeze approximately €6 billion in spending, including roughly €4 billion for the central government and €2 billion for social security, according to Le Monde . Lescure stressed that the government would stop short of outright budget cuts, describing the freeze as “precautionary measures” that could be unfrozen “if things improve” .
2. Targeted Energy Support
New measures to help consumers manage higher energy prices will be announced, with a particular focus on people who rely on vehicles for work. So far, France has focused on emergency fuel subsidies for the transport, fishing, and farming sectors .
The government is under competing pressures: the far right has called for a costly cut in the 20% value‑added tax on fuel, while the hard-left has demanded energy price caps . However, given France’s fiscal constraints, Lescure indicated that the government can only afford strictly targeted support .
Economic Growth Downgraded
The war has also forced France to lower its economic outlook. Earlier this month, the government reduced its forecast for economic growth this year to 0.9% from the 1% included in the 2026 budget bill. Inflation is now expected to be faster than previously anticipated at 1.9% instead of 1.3% .
The downgrade reflects the broader impact of the conflict on European economies. The effective closure of the Strait of Hormuz, through which approximately 20% of the world’s oil passes, has sent global energy prices soaring, contributing to inflationary pressures across the continent.
The Ceasefire Context
Lescure’s announcement comes as the two-week ceasefire brokered by Pakistan between the US and Iran is set to expire on April 22, 2026 . The truce, which took effect on April 7, was explicitly conditioned on Iran’s agreement to the “COMPLETE, IMMEDIATE, and SAFE OPENING” of the Strait of Hormuz — a condition Iran has not met.
The US has imposed a naval blockade on Iranian ports, which France and other European nations have declined to support, preferring instead to pursue a “peaceful multinational mission” to restore navigation after the conflict ends .
European Impact Beyond France
France is not alone in feeling the economic pain. European nations across the continent are grappling with:
- Soaring energy prices: Oil and natural gas costs have surged, impacting households and industry
- Supply chain disruptions: The closure of the Strait of Hormuz has blocked critical shipping routes
- Inflationary pressures: Higher energy costs are feeding into broader price increases
- Fiscal strain: Governments face pressure to provide relief while deficits widen
The International Monetary Fund (IMF) is expected to revise down its forecast for global economic growth this year due to the conflict, with European economies among the most exposed.
What Comes Next
As the ceasefire expiration approaches, several factors will determine the trajectory of the economic impact:
| Factor | Current Status | Potential Impact |
|---|---|---|
| Ceasefire expiration | April 22, 2026 | Expiration could worsen economic outlook |
| US naval blockade | Ongoing | Blocking Iranian oil exports |
| Second round of talks | Stalled; Iran has not committed | Diplomatic resolution uncertain |
| Energy prices | Elevated near $100/barrel | Sustained inflationary pressure |
The €4-6 billion estimate is likely to grow if the conflict persists. Lescure himself noted that “this crisis is still extremely uncertain in its course, in its economic impact and in its impact on public finances” . For now, France is bracing for continued economic turbulence as the diplomatic window narrows.
