Strait of Hormuz closure drives global energy shock
The defining geopolitical event for supply chains in this cycle is the ongoing US-Israel-Iran conflict and the effective closure of the Strait of Hormuz — the corridor through which roughly 20% of global oil supply normally transits.
Brent crude reportedly spiked to $119 per barrel in mid-March 2026, while governments moved into emergency response mode. Measures now include reserve releases, export bans, price caps, work-from-home mandates, and temporary sanctions waivers designed to keep energy moving through alternative channels.
The result is not just a market shock. It is a third-party risk event affecting logistics, manufacturing, cloud infrastructure, and any vendor whose delivery model depends on stable energy pricing or Middle Eastern transit corridors.
Key facts
Brent crude rose sharply; the IEA agreed to release 400 million barrels from emergency reserves; repeated attacks on energy infrastructure have intensified disruption.
Temporary measures
US waivers were issued for Russian oil at sea, Venezuelan oil transactions, domestic shipping capacity, and short-term Iranian oil purchases.
Third-party risk implication
Energy-dependent vendors face cost escalation, pricing volatility, and possible supply interruption. The mix of sanctions waivers creates added compliance ambiguity for vendors operating in distressed energy markets.
Exposure areas
Data centers, manufacturing vendors, transport and logistics providers, import-heavy suppliers, and vendors reliant on Middle Eastern energy infrastructure or transit routes.
Recommended actions
- Map all third-party dependencies on energy sourced through the Strait of Hormuz.
- Assess the continuity plans of critical vendors exposed to Middle Eastern energy infrastructure.
- Review sanctions compliance programs where temporary waivers may create operational confusion.
- Monitor Brent crude direction and model the impact on vendor pricing and service cost inflation.

Sanctions
Expanding sanctions regimes are reshaping vendor risk
Sanctions activity remains one of the most operationally significant geopolitical forces affecting third-party ecosystems. The EU, UK, and US are all adjusting pressure points, but not in a linear way: new restrictions, selective de-listings, cyber sanctions, and secondary-sanctions logic are all occurring at once.
The EU’s 19th Russia package, the coming Russian LNG ban, expanded cyber sanctions, active UK secondary-sanctions behavior, and OFAC list volatility together create a compliance landscape where static annual screening is no longer credible.
Russia-related developments
EU 19th package includes LNG restrictions from January 2027, lower oil price cap, export restrictions, and measures affecting roughly 2,600 persons and entities.
Cyber sanctions
The EU expanded its cyber sanctions framework to cover additional Chinese and Iranian-linked entities tied to attacks and disruptive operations.
US and UK signal
UK sanctions show real use of secondary-sanctions style pressure. OFAC’s list activity remains dynamic, with both de-listings and new designations occurring frequently.
Third-party risk implication
Vendors with Russia, Belarus, Iran, China-linked sanctioned exposure, or indirect energy trade exposure may create legal, reputational, and continuity risks. Weekly screening is becoming the practical minimum.
Recommended actions
- Run updated sanctions screening across all third parties using the latest EU, UK, and US lists.
- Assess vendor exposure to Russian LNG and gas ahead of January 2027 and January 2028 milestones.
- Evaluate secondary sanctions exposure for vendors headquartered in China, India, or Southeast Asia.
- Review technology vendor contracts for any exposure to EU-sanctioned Chinese cyber entities.
- Ensure sanctions screening tools refresh at least weekly.
