Berkshire’s Hormuz Hesitation Signals Institutional Skepticism on Strait Stability
Warren Buffett's insurance arm joins US-backed program but hasn't written a single policy—a price-dependent stance that contradicts de-escalation optimism.
Berkshire Hathaway has joined a US government-backed insurance program for Strait of Hormuz shipping but hasn’t underwritten any policies, with Vice Chairman Ajit Jain stating participation depends on pricing and naval escort guarantees—a conditional stance that signals institutional caution rather than confidence in corridor stabilization.
Speaking at Berkshire’s annual meeting on May 2, Jain confirmed the firm has CNBC “taken a small participation in a program that’s been put in place so as to write Insurance for the ships in the Strait of Hormuz” but crucially added: “We haven’t written any deals as yet.” When pressed on underwriting appetite, Jain’s response was unambiguous: “The short answer is—depends on the price.”
The Strait of Hormuz, a chokepoint carrying 20% of global oil supply, has been effectively closed to commercial traffic since February 28 following US-Israel strikes on Iran. A ceasefire agreed April 8 collapsed within days when the US refused to lift its naval blockade of Iranian ports, triggering Iran’s reassertion of control over the waterway.
Premiums Remain Elevated Despite Government Backstop
War-risk insurance premiums sit at 1-3% of vessel value as of May 3—translating to $6-8 million for large tankers—according to Khaleej Times. While down from a February peak of 10%, current rates remain 4-12 times pre-conflict levels of 0.25%. The US doubled reinsurance guarantees to $40 billion in April and recruited Berkshire, AIG, and Chubb as private partners after the commercial insurance market effectively collapsed. Yet the pricing gap persists.
Strait traffic remains at approximately 5% of pre-war levels—around 150 vessels per month versus 3,000 previously—per data from CNN. Roughly 2,000 ships remain stranded in the Persian Gulf, unable to secure coverage at commercially viable rates. Iran has limited passage to approved vessels and imposed tolls exceeding $1 million per ship.
Ceasefire Fragility Undermines Underwriting Confidence
The April ceasefire unraveled within 24 hours of its announcement. Iran declared on April 17 that the Strait would open to commercial traffic, only to reverse the decision April 18 when the US refused to lift its blockade. Oil prices tumbled more than 10% on the initial announcement before spiking 5.6-6% as tankers came under fire April 19-20, CNBC reported at the time.
Insurance underwriters are demanding sustained evidence of threat reduction before premium compression. Analysts quoted by Al Jazeera specified requirements: “a durable ceasefire or political resolution, clear naval security guarantees, consistent freedom of navigation, no recent vessel seizures or attacks, credible mine clearing and surveillance, and predictable rules of engagement among the key military actors in the region.” None of these conditions currently exist.
“Insurance rates will fall—and the willingness of commercial operators to insure and send cargoes through the Strait will rise—only after Iran’s military capabilities are degraded.”

Government Backstop Fails to Close Risk-Pricing Gap
The $40 billion federal reinsurance program announced April 6 aimed to restore private market participation, Insurance Journal reported. Yet Berkshire’s zero-policy track record reveals a fundamental disconnect: government capital alone cannot substitute for political stability signals that would justify lower premium floors.
Jain’s emphasis on US Navy escorts as a precondition for underwriting indicates Berkshire views unaccompanied transits as uninsurable at any price the market will bear. This conditional participation framework suggests the firm is positioning for potential entry once risk metrics improve, but sees current conditions as mispriced relative to actual threat exposure.
Macro Signal: Institutional Capital Waits for Political Resolution
Berkshire’s participation-without-commitment posture reflects broader institutional reluctance to price geopolitical tail risk absent credible de-escalation. The firm’s reputation for disciplined underwriting makes its hesitation particularly significant: if Berkshire won’t write coverage with a $40 billion government backstop, the private market’s implicit assessment is that current conditions remain uninsurable at commercially sustainable rates.
This dynamic creates a self-reinforcing cycle. Elevated premiums deter traffic, minimal traffic prevents the stability data insurers require for premium compression, and without premium compression, stranded capacity remains offline. According to Khaleej Times, underwriters are waiting for months of uninterrupted operations before considering rate adjustments—a timeline that appears incompatible with current geopolitical volatility.
- Berkshire joined US Hormuz insurance program but hasn’t issued a single policy, with pricing and naval escorts as preconditions
- War-risk premiums at 1-3% of vessel value remain 4-12x pre-conflict levels despite $40B government backstop
- Strait traffic at 5% of normal levels; April ceasefire collapsed within 24 hours
- Insurers require months of uninterrupted operations before premium compression—incompatible with current political trajectory
- Institutional hesitation signals risk-pricing disconnect between government program design and underwriter threat assessment
What to Watch
Monitor Berkshire’s first policy issuance as a binary indicator of institutional confidence in corridor security. Any premium below 1% of vessel value would signal meaningful de-escalation; rates above 2% suggest underwriters still price substantial kinetic risk. Track US Navy escort commitment language in Pentagon briefings—explicit guarantee protocols would address Jain’s stated precondition. Watch for sustained 30-day periods without vessel seizures or attacks, the minimum stability window insurers indicated would trigger preliminary premium reviews. Finally, observe whether alternative routing via Cape of Good Hope maintains market share despite 3,500-mile detour costs—persistent avoidance behavior would confirm institutional skepticism of Strait security regardless of government assurances.
