## Prediction

Over the next week, the US and EU will likely announce incremental sanctions or enforcement actions targeting Russian defense-industrial suppliers and Iranian maritime and drone-related entities, framed as responses to battlefield escalation and attacks on US assets. Measures will focus on closing loopholes, targeting intermediaries, and reinforcing existing regimes rather than sweeping new embargoes. The direct near-term macroeconomic impact will be modest but will add friction to Russian and Iranian procurement channels. Secondary sanctions risk will further chill some third-country trade with these actors.

## Drivers

- Recent US sanctions on Iran’s Persian Gulf Strait Authority
- EU hardening stance on Russia and calls for force limits
- US domestic pressure after Iranian strike on Kuwait base
- Pattern of sanction ratcheting in response to escalatory events
