How the Panama and Suez Canals Shape Global Trade — and Why They're Both Vulnerable

The Panama Canal (5% of global trade) and Suez Canal (12% of global trade) are critical chokepoints. Panama: drought lowered water levels, restricting ship size and increasing transit costs. Suez: Red Sea Houthi attacks diverted traffic around Cape of Good Hope (10-14 day detour). Both vulnerabilities highlight supply chain fragility. Alternatives: Nicaragua Canal (stalled), Northern Sea Route (Arctic ice melting), and Suez Canal expansion. The real lesson: critical infrastructure concentrated in two narrow waterways creates systemic risk that affects every consumer through higher shipping costs.
