Kharg Island no longer under Iranian control by March 31, 2026

This is a military logistics and timeline analysis, not a Federal Reserve prediction. The key question is whether Iran will lose control of Kharg Island by March 31, 2026—just 6 days from today (March 25, 2026).

Step 1: Current Status Assessment

• Iran maintains primary governmental and military control through thousands of IRGC personnel (as of March 25, 2026)
• U.S. conducted massive airstrikes on March 13, destroying 90+ military sites but deliberately sparing oil infrastructure
• Crucially, the resolution criteria explicitly exclude temporary bombardment—actual occupation and transfer of control is required

Step 2: Pentagon Timeline

• Pentagon officials stated on March 24, 2026 that any ground operation would not occur for "approximately one month"
• This timeline extends well beyond the March 31 resolution deadline
• Military deployments (82nd Airborne, 5,000 Marines) are accelerating but these units are still in transit/staging

Step 3: Military Logistics Reality Check

• Modern amphibious operations against heavily defended strategic targets require extensive preparation
• Historical precedent: Iwo Jima took 5 weeks of combat after months of planning; Falklands took 10 weeks
• A successful invasion, occupation, and establishment of control within 6 days would be unprecedented
• Base rate for such rapid control transfer: effectively 0-5%

Step 4: Resolution Criteria Strictness

• Must be actual transfer of governmental/military control
• Temporary raids, special operations, bombardment, naval presence—all explicitly excluded
• If control is contested, unclear, or disputed by March 31, resolves NO
• This is a high bar requiring clear, unambiguous control transfer

Step 5: Tail Risk Assessment

• Could Iran suddenly collapse or negotiate a surprise transfer? Non-zero but highly improbable given:
  • IRGC's entrenched defensive position
  • Strategic importance (90% of Iran's oil exports)
  • No credible reporting suggesting imminent capitulation
  • No indication of negotiated settlement in progress

Step 6: Market Comparison

• Market prices this at 7.5% (0.075)
• This seems to appropriately price in small tail risks: sudden Iranian collapse, unannounced special operations success, or surprise diplomatic deal
• However, given Pentagon's explicit one-month timeline and only 6 days remaining, even 7.5% appears slightly generous

Conclusion: Estimated probability 2% This accounts for extreme tail risks (surprise Iranian surrender, covert operation already underway but not yet public, catastrophic internal collapse) while recognizing that Pentagon's own March 24 statement essentially rules out a March 31 control transfer under normal military planning.

SLIGHT EDGE TO NO: Market probability of 7.5% appears slightly overpriced given Pentagon's explicit one-month timeline and only 6 days remaining. Estimated true probability is ~2%, suggesting the market is overweighting tail risks by ~5.5 percentage points. However, this is a relatively modest edge (not a huge mispricing), and given the extreme uncertainty of geopolitical/military situations, the difference between 2% and 7.5% is within reasonable calibration bounds.

The market may be rationally pricing in scenarios invisible to public analysis: classified intelligence suggesting faster timelines, or giving higher weight to Iranian collapse scenarios. Additionally, in highly volatile military situations, option value of unexpected developments may justify market's higher probability.

RECOMMENDATION: Weak NO bet (betting Iran retains control through March 31). The edge exists but is modest. Given low absolute probabilities on both sides, transaction costs, and geopolitical unpredictability, this is not a strong conviction opportunity. Only bet if you have very low friction costs and can accept that 2-8% tail events do occur.
