Global Defense Supply Chains Strained as US–Iran and Russia–Ukraine Wars Consume Munitions

Moderate confidence (72%)
Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over 30 days, parallel conflicts with Iran and Russia will significantly strain Western and allied arms production, leading to delayed deliveries, rationing of high‑end munitions, and increased prices across the defense industrial base. Allies reliant on U.S. precision weapons, air defenses, and drones will face difficult allocation choices between their own stocks and exports to frontline partners. This will open space for non‑Western suppliers (Russia, China, regional producers) to capture arms market share where sanctions permit. Confirmation would be official warnings about depleted stocks, delayed contracts, and emergency production surges; denial would require either rapid de‑escalation in one theater or previously undisclosed large reserve stocks.
Drivers
- Emerging trend: US–Iran war strain drives global weapons shortages and alliance stress

- NATO states
- Gulf countries
- Asia–Pacific allies
Affected assets
