Ship spoofing rise in Strait of Hormuz complicates US naval operations

Windward reports a rise in ship spoofing in the Strait of Hormuz, complicating US naval operations. The likelihood of the UK sending warships through the strait by April 30 is now at 8.5% YES, up from 4% a week ago.

Market reaction

The UK warships in the strait market has moved 4.5 percentage points over the past week. The increase in electronic deception tactics points to Iran leaning harder on asymmetric warfare against the US blockade, which could push the UK toward deploying naval forces as diplomatic pressure builds.

Meanwhile, odds on Trump announcing the lifting of the US blockade by May 31 have slipped. The Trump blockade announcement market is at 83.5% YES, down from 84% yesterday. Continued spoofing makes a near-term de-escalation announcement less probable.

Why it matters

The warship market trades $29,185/day in face value but only $2,627/day in actual USDC. It takes just $942 to shift the odds by 5 points, which means the market is thin and prone to sharp moves. A three-point spike at 7:21 PM shows how quickly a single large buy order can move the price.

The spoofing increase looks more like a strategic shift than a one-off event. At 8.5¢, a YES share on UK warship deployment pays $1 if it resolves, a 11.8x return. That bet requires believing the UK will act within 15 days.

What to watch

Statements from the UK Ministry of Defence or evidence of allied naval movements near the strait. Either could shift deployment expectations and move the market.
