Weekly Risk Snapshot – March 2026: Oil, Treasuries, Anthropic

1. Energy Stagflation Shock (Strait of Hormuz)

What Changed
P&I Clubs (London P&I, Skuld, American Club, et al.) revoked war risk coverage for commercial vessels in the Persian Gulf and Gulf of Oman, triggering the standard 72-hour notice period. The U.S. responded with DFC sovereign guarantees and U.S. Navy readiness to escort tankers.​

Why It Matters
Insurers' decision effectively blocked access to ~20% of global crude oil and LNG supply. The key driver wasn't Iranian blockade but actuarial risk models of insurance syndicates. Even OPEC+'s announced production increase becomes meaningless as spare capacity is physically trapped within the conflict zone.​

Amplified Risk
Global stagflationary shock, cascading maritime logistics paralysis, energy shortages across Asia and Europe.​

2. Safe-Haven Pattern Breakdown (U.S. Treasuries)

What Changed
10-year U.S. Treasury yields surged above 4.1% and continued climbing amid the largest Middle East conflict in two decades.​

Why It Matters
Instead of classic "flight to quality," investors are pricing persistent inflation from rising oil prices (Brent > $84), outweighing safe-haven demand. This signals expectations of prolonged tight Fed policy.​

Amplified Risk
Higher corporate cost of capital, de-rating of long-duration assets (tech), mortgage rates returning to ~6% pressuring housing.​

3. AI Infrastructure Politicization (Anthropic vs. Pentagon)

What Changed
U.S. DoD designated Anthropic a "supply chain security threat" for refusing to lift ethical restrictions on Claude for domestic surveillance and autonomous weapons systems.​

Why It Matters
First use of national security tools—originally designed against foreign adversaries—against a domestic AI leader. Pentagon contractors and cloud providers risk losing federal contracts if they continue commercial relationships with Anthropic.​

Amplified Risk
U.S. AI ecosystem fragmentation, vendor lock-in to "compliant" providers, sudden loss of AI infrastructure access for civilian business...
