Grok:
As of late March 2026 (about four weeks into the conflict), the U.S.-Israel military campaign against Iran—launched on February 28, 2026, and known as Operation Epic Fury—has involved extensive airstrikes, naval operations, and strikes on Iranian military infrastructure, leadership targets, and proxies.

Direct U.S. military costs so far are estimated in the range of $12–25+ billion, with projections for significantly higher totals if the conflict continues. These figures come from Pentagon briefings, Trump administration statements, and independent analyses, though exact accounting is incomplete (e.g., it may exclude full pre-war buildup, long-term replenishment, or indirect costs like veteran care).Key cost breakdowns
- The first six days alone cost at least $11.3 billion, primarily on precision munitions (e.g., missiles costing $1–4 million each vs. cheap Iranian drones at ~$20,000).

- By mid-March (around day 15–18), Trump economic adviser Kevin Hassett cited ~$12 billion; other estimates (e.g., Center for Strategic and International Studies) put it at ~$16.5 billion by day 12, with early daily burn rates near $891 million to $1 billion.

- As of late March, cumulative costs have likely exceeded $20–25 billion (and could hit that threshold by the end of the week of March 24), with daily spending now lower due to a reduced operational tempo and cheaper munitions.

- Pre-war military buildup in the region added hundreds of millions (one estimate: ~$630 million).

- The Pentagon is seeking a $200 billion supplemental appropriation for ongoing operations, munitions replenishment, and related costs—on top of the regular defense budget. Longer scenarios project $40–95 billion for a two-month conflict or up to hundreds of billions (potentially trillions long-term) if it drags on.

These are taxpayer-funded direct outlays for munitions, aircraft carrier operations, air sorties, and lost/damaged equipment. They do not include U.S. casualties (early reports noted at least 13 service members killed and others injured) or broader economic ripple effects like higher domestic energy prices.

Global supply chain disruptionsThe conflict has severely disrupted the Strait of Hormuz—a critical chokepoint carrying ~20–31% of global seaborne crude oil and significant liquefied natural gas—leading to near-halt of tanker traffic, attacks on vessels, and widespread rerouting.

- Oil and energy: Regional production has been slashed (by more than two-thirds in some estimates), spiking global crude prices above $100/barrel for the first time since 2022. In the U.S., gasoline prices rose roughly a third (to an average around $3.98/gallon early on), with diesel climbing even higher (near $5/gallon in some reports). This drives inflation in transportation, manufacturing, and consumer goods worldwide.

- Shipping and logistics: Over 150 vessels (including oil/LNG tankers) were stranded or anchored; at least four tankers damaged/ablaze, with insurance companies canceling war-risk coverage or imposing massive premium hikes. Many carriers reroute around the Cape of Good Hope (adding 10–14 days and higher fuel costs per voyage), causing port backups, container shortages, and elevated freight rates across Asia-Europe and other lanes. About 10% of global container ships have been affected.

- Other commodities: Beyond oil, disruptions hit oil-derived products like fertilizers (raising food prices), pharmaceuticals and specialty chemicals (e.g., from India/Middle East routes), semiconductors/electronics (via broader Asian shipping delays), and helium. Industrial production and global supply chains face knock-on shortages and cost increases.

In short, the direct U.S. military price tag is already in the tens of billions after one month, with a requested $200 billion supplemental on the table. Supply-chain chaos—centered on the Strait of Hormuz—has driven energy price spikes, shipping delays, and inflationary pressures globally, affecting everything from fuel to food and manufactured goods. Figures are estimates and will evolve with the conflict’s duration; the war remains ongoing with no clear end date as of March 27, 2026.
