## Prediction

Within 7 days, major maritime insurers and compliance departments will tighten risk assessments and possibly premiums for vessels explicitly linked to Iranian ownership or trade, in response to US rhetoric that 'all Iranian tankers are at risk worldwide.' Some shipping companies will quietly avoid charters involving Iranian crude and products, leading to a slight decrease in effective Iranian export capacity even absent new sanctions. This will increase Iran’s reliance on shadow fleet operations and complex transshipment schemes. A contrarian outcome would be a quiet US assurance to key insurers to prevent excessive market disruption, but this is less likely given current rhetoric.

## Drivers

- Trump and Hegseth’s explicit global threats to Iranian tankers
- Past patterns of insurance market responses to heightened conflict risk
- Sustained trend of sanctions and enforcement pressure on Iranian shipping
