Iran War & Business Impact — Sanctions, Contracts, and Legal Exposure

I own an import/export company that does significant volume through the Persian Gulf region. We don’t trade directly with Iran, but we have clients in the UAE, Oman, and Turkey who do, and we handle transshipment logistics for goods that may have Iranian-origin components.

With Operation Epic Fury, I’m bracing for a massive expansion of sanctions. My immediate concerns:

• OFAC compliance: Are we about to see a new round of executive orders expanding the SDN list and secondary sanctions? How fast do these typically roll out during active military operations?
• Contract performance: We have existing contracts with delivery obligations through the Strait of Hormuz. If shipping insurance gets pulled or routes become impassable, can we invoke force majeure?
• IEEPA authority: The administration has been using IEEPA (International Emergency Economic Powers Act) aggressively for tariffs — SCOTUS just struck that down. Does the Iran situation give them a stronger IEEPA footing for actual sanctions?
• Oil price contracts: We have several clients with fixed-price fuel supply agreements. Crude is already spiking. Who bears that risk?

I need practical guidance on protecting my business and my clients over the next 30-90 days. This feels like it could be existential for companies in our space.

Sanctions attorney here. Let me address the IEEPA and OFAC questions first, because this is where I expect the fastest regulatory movement.

IEEPA and Iran Sanctions — Distinct from the Tariff Cases:

You’re right that the Supreme Court recently held that IEEPA (50 USC §§1701-1706) does not authorize the imposition of tariffs, since the statute expressly excludes “the authority to regulate or prohibit” imports in a way that functions as a tariff. That ruling was about the misuse of IEEPA for trade policy purposes it was never designed for.

Iran sanctions are an entirely different matter. IEEPA was specifically designed for situations like this — national emergencies arising from foreign threats. Iran has been subject to IEEPA-based sanctions since Executive Order 12170 (1979). The legal foundation for Iran sanctions under IEEPA is rock-solid and has been upheld repeatedly. The SCOTUS tariff ruling does not affect the administration’s authority to expand Iran sanctions.

What to expect:

• New Executive Orders within days, possibly hours. During active military operations, OFAC typically issues new designations and expands sanctions programs rapidly. Expect a significant expansion of the SDN (Specially Designated Nationals) list targeting Iranian military, government, and commercial entities.
• Secondary sanctions expansion. This is where it hits your clients. Secondary sanctions under the Comprehensive Iran Sanctions, Accountability, and Divestment Act (CISADA) and subsequent EOs penalize non-US persons for doing business with designated Iranian entities. Your UAE, Oman, and Turkey clients could face secondary sanctions risk for their Iran-related trade.
• Transshipment scrutiny. OFAC has been intensifying enforcement against transshipment schemes that route Iranian-origin goods through third countries. If your logistics operations touch goods with Iranian-origin components, your compliance exposure just increased dramatically. Review your KYC procedures immediately.

Immediate action items: Run a fresh SDN screening on all counterparties. Review all contracts involving Persian Gulf logistics for Iran nexus. Brief your compliance team on enhanced due diligence requirements. Consider engaging outside sanctions counsel if you don’t already have one.

Supply chain risk consultant here. Not a lawyer, but I can speak to the operational side of what’s about to hit.

Strait of Hormuz: Roughly 20% of the world’s oil and a significant volume of LNG and dry cargo transits the Strait daily. Even before Iran responds militarily (and they will respond), insurers are already reassessing war risk premiums for the entire Persian Gulf. I’m hearing from contacts in London that Lloyd’s syndicates are pricing war risk premiums for Gulf transits at 3-5% of hull value, up from fractions of a percent yesterday. For a large container vessel, that’s potentially millions of dollars per transit.

Shipping disruptions: Multiple major container lines have already announced they’re rerouting around the Cape of Good Hope, adding 10-14 days to Asia-Europe routes. This is the Houthi/Red Sea playbook from 2024, but potentially worse because the Strait of Hormuz is a much more critical chokepoint than Bab el-Mandeb.

Practical impacts for import/export firms:

• Lead times for any goods transiting the Persian Gulf region are about to extend dramatically.
• Shipping costs will spike — and those costs flow through to your clients and their contracts.
• Marine cargo insurance policies with war exclusion clauses (which is most of them) may not cover losses in the region. Check your policies today.
• Letters of credit may be affected if correspondent banks in the region restrict operations.

@TradeRouteLogistics_Karen — if you have cargo currently in transit through the Gulf, contact your freight forwarder and insurer immediately. Don’t wait for the situation to escalate further.

International trade attorney. Let me address the force majeure and contract performance questions, because these are going to be the bread-and-butter disputes for the next year.

Force majeure clauses: Whether you can invoke force majeure depends entirely on the language of your specific contract. There is no universal force majeure doctrine in US law (unlike some civil law jurisdictions). You need to look at:

• Is “war” or “military action” listed as a triggering event? Most well-drafted commercial contracts include war, hostilities, or government action as enumerated force majeure events. If yours does, you likely have a viable claim — but you still need to show the war actually prevents your performance, not just that it makes it more expensive.
• The “impracticability” vs. “impossibility” distinction: Under UCC §2-615, a seller may be excused when performance becomes “impracticable” due to an unforeseen contingency. This is a lower bar than impossibility. If your shipping routes through the Strait of Hormuz become uninsurable or subject to military risk, that likely meets the impracticability standard even if alternative routes exist — because the cost differential may be commercially unreasonable.
• Notice requirements: Almost every force majeure clause requires timely notice to the other party. If you think you may need to invoke force majeure, send written notice now, even if you’re not yet certain performance will be affected. Late notice can waive your rights entirely.

Oil price contracts and fixed-price fuel agreements: This is trickier. Commodity price fluctuations, even dramatic ones, are generally not force majeure events unless the contract specifically covers them. Courts have repeatedly held that price increases alone do not excuse performance. See Hess Energy Trading Co. v. Lightning Oil Co. and similar cases. Your clients with fixed-price fuel supply agreements are likely stuck with those prices unless the contract has a specific price adjustment mechanism or market disruption clause.

However: If the price spike results from a supply disruption that makes physical delivery impossible (not just expensive), that’s a different analysis. If your client literally cannot source the fuel at any price because of sanctions or supply chain collapse, that’s impracticability, not just a bad price.

Marine insurance broker, 15 years specializing in war risk and political violence coverage. Let me fill in the insurance picture.

War exclusion clauses: Standard marine cargo policies (based on the Institute Cargo Clauses) contain a war exclusion under Clause 6 of ICC(A). This excludes loss caused by “war, civil war, revolution, rebellion, insurrection, or civil strife arising therefrom, or any hostile act by or against a belligerent power.” US military strikes against Iran clearly constitute hostile acts by a belligerent power. Any cargo loss in the Persian Gulf region attributable to the conflict will almost certainly be excluded under standard policies.

War risk cover: Separate war risk policies are available, but here’s the problem: most war risk policies have a 7-day cancellation clause for listed areas. The Joint War Committee (JWC) at Lloyd’s has already expanded the listed area to include the entire Persian Gulf, Gulf of Oman, and parts of the Arabian Sea. Existing war risk policies for these areas can be cancelled on 7 days’ notice, and new coverage will be priced at the dramatically higher rates @RajeshGupta_SupplyChain mentioned.

What this means practically:

• If you have cargo in transit through the Gulf right now, check whether your war risk cover is still in force. Don’t assume it is.
• New shipments through the region will require war risk premiums that may make the shipment commercially unviable. This is not hypothetical — it’s already happening.
• Political violence and terrorism insurance for onshore operations in the Gulf states may also face exclusions or premium spikes. If your clients have facilities in the UAE or Oman, review those policies.
• Trade credit insurance — if your counterparties in the region can’t perform, your trade credit insurer may invoke the war exclusion to deny claims on receivables.

I’m already getting requests to place coverage at rates I’ve never seen. The insurance market for this region is going to be extremely tight for the foreseeable future.

Quick update — OFAC has already issued a new FAQ this morning indicating that “significantly expanded designations” under the Iran sanctions program are forthcoming. They’re also signaling enhanced enforcement of existing secondary sanctions authorities.

One critical point for everyone in this thread: The penalties for sanctions violations are severe. Under IEEPA, civil penalties can reach $356,579 per violation (as adjusted for inflation), and criminal penalties can reach $1 million and 20 years imprisonment per violation. 50 USC §1705. “Strict liability” applies to civil violations — you don’t need to know you were dealing with a sanctioned party to be liable.

If your business has any Iran-adjacent exposure — even indirect, even through third-country intermediaries — this is the moment to get your compliance house in order. The enforcement environment during active military operations is dramatically more aggressive than peacetime.

This thread has been incredibly valuable. Let me summarize my action items based on everyone’s input:

1. Immediate SDN rescreening of all counterparties, especially UAE, Oman, and Turkey contacts with any Iran nexus. Engaging @DavidStern_SanctionsLaw’s firm for outside sanctions counsel review.
2. Force majeure notices going out today on all contracts with Strait of Hormuz delivery obligations, per @NataliePrice_TradeLaw’s advice. Better to notify early and not need it than to miss the window.
3. Insurance review — calling our marine broker this morning to confirm war risk coverage status on in-transit cargo and assess new premiums. Also reviewing trade credit policies for war exclusions.
4. Client communication — proactively reaching out to clients with fixed-price fuel agreements to discuss price adjustment mechanisms before crude prices spike further.
5. Enhanced KYC/due diligence on all transshipment operations touching the Persian Gulf region. Pausing any shipments with potential Iranian-origin components until compliance review is complete.
6. Contingency routing — working with freight forwarders on Cape of Good Hope alternatives, even though the cost and time implications are painful.

Thank you to @DavidStern_SanctionsLaw, @RajeshGupta_SupplyChain, @NataliePrice_TradeLaw, and @TomBrennan_MarineInsurance. This is exactly the kind of cross-disciplinary analysis I needed. Will update as the situation develops.
