US blocks $500M cash to Iraq, pressuring Iran-backed militias

The U.S. blocked a $500 million cash shipment to Iraq to pressure Baghdad into dismantling Iran-backed militias. The move has pushed the likelihood of a US-Iran nuclear deal by April 30 down to 6.5% YES, and odds on Trump agreeing to Iranian oil sanction relief in April have fallen sharply.

Trump agreeing to Iranian oil sanction relief in April dropped to 14% YES, down from 26% a day ago. Daily actual USDC volume is $1,814, and it takes only $416 to move the odds by 5 points, meaning thin liquidity and room for sharp swings.

The US-Iran nuclear deal by April 30 market fell to 6.5% YES from 20% over 24 hours. A 2-point drop at 9:47 AM was driven by $11,881 in actual USDC traded. The Treasury’s cash blockage signals intensified U.S. pressure on Iran and makes a deal within the next week less likely.

The cash blockage points to a hardening U.S. stance on Iran-Iraq relations, with direct consequences for regional stability and energy supply expectations. For traders, the contrarian angle: buying YES in the nuclear deal market at 6.5¢ pays $1 if resolved, a potential 15.4x return, though the risk is obvious given the direction of U.S. policy.

Watch for shifts in U.S. diplomatic language or direct engagement with mediators like Oman or Turkey. Either could move these markets quickly.
