As the US-Israeli military campaign against Iran enters its eighth day (March 6, 2026), the economic toll is mounting rapidly. Beyond battlefield casualties and geopolitical shockwaves, the war is burning through tens of billions of dollars—hitting defense budgets, energy markets, global supply chains, and inflation expectations worldwide. Here is a breakdown of the hard numbers emerging from Western and regional estimates.
Direct Military Costs – US & Israel
- United States Daily operational expenditure is estimated between $1 billion and $2 billion, according to preliminary assessments by defense analysts and congressional staffers.
- CSIS (Center for Strategic and International Studies) places the figure at approximately $891 million per day (as of March 5), assuming current tempo of B-2, F-35, and naval missile strikes, plus carrier group sustainment.
- Costs rise sharply when factoring in high-end munitions (JASSM-ER, Tomahawk Block V, JDAMs), aerial refueling, and electronic-warfare support. A single B-2 sortie can cost upwards of $150 million in direct operating expenses.
- Troop deployment (several thousand additional personnel across CENTCOM bases) and heightened alert status across the region add tens of millions more daily.
- Israel The Israeli Ministry of Finance privately briefed that each week of the current intensity costs roughly $3 billion (≈₪11 billion).
- This covers Iron Dome, Arrow-3, and David’s Sling interceptors (each Arrow-3 round ≈ $2–3 million), fighter jet sorties (F-35I fuel & maintenance), reserve call-ups, and economic disruption (closed airspace, halted commercial flights, tourism collapse).
- Israel is still recovering from the Gaza war (2023–2025), which left a budget deficit of nearly 8% of GDP and public debt above 70% of GDP. The new front is pushing the deficit toward double digits.
Energy Market Shock – Global Collateral Damage
Iran’s retaliatory strikes and the near-total disruption of the Strait of Hormuz have sent energy prices soaring:
- Brent crude rose to $87 per barrel (+20% since February 28), the highest since July 2024. Futures climbed another 1.8% on March 6.
- European natural gas (TTF hub) surged 62% in one week, reaching €51 per MWh, with some contracts briefly touching levels not seen since the 2022 Russia-Ukraine peak.
- Bloomberg reports that weekly gas futures have risen more than 60% since the conflict began.
- The Institute of International Finance (IIF) warns:
- Oil at $80/barrel shaves 0.2% off global GDP.
- Oil at $100–110/barrel subtracts 0.6% from global output—roughly $600–700 billion in lost economic activity annually if sustained.
- Shipping: Interactive maps by journalist Mahmoud Al-Kan show tanker traffic through Hormuz down 80–90%. Hundreds of vessels are idling in the Gulf of Oman and Arabian Gulf, creating floating storage and massive demurrage costs (up to $100,000–$200,000 per day per VLCC).
Secondary & Tertiary Damage
- Saudi Arabia & Kuwait: Strikes on Ras Tanura refinery and other facilities have disrupted production and storage. Saudi Arabia has activated emergency drawdowns, but export capacity is constrained.
- Global supply chains: Shipping companies (Maersk, MSC, Hapag-Lloyd) have suspended Gulf calls; rerouting around Africa adds 10–14 days and $1–2 million per voyage in fuel and insurance.
- Inflation risk: Keith Boyfield (Centre for Policy Studies, London) warns that a month-long conflict could double global inflationary pressure, especially for Asia’s net oil importers (India, China, Japan, South Korea).
- Europe’s buffer: The EU’s strategic petroleum reserve (~2 billion barrels equivalent) offers temporary relief, but prolonged disruption would still feed through to consumer prices within 60–90 days.
The Bottom Line – A War Measured in Billions
- US daily burn rate: $1–2 billion
- Israel weekly burn rate: $3 billion
- Global oil/gas market shock (first week): tens of billions in lost value and higher import bills
- Projected global GDP hit (if oil reaches $100+ sustained): 0.6% (~$600–700 billion annually)
This is not a cheap war. Unlike previous US-led campaigns in the region, the current conflict combines high-intensity air operations, expensive missile defense expenditures, and immediate global energy-market contagion. For Washington and Tel Aviv, the financial ledger is darkening by the hour—and for the rest of the world, the inflationary aftershocks are only beginning. If the fighting drags beyond a month, the “war of billions” could easily become the most expensive Middle East conflict of the 21st century.
