  2. US Patriot Aid Package and Black Sea Mining Risks43Approved multi-billion-dollar military aid alongside ongoing Black Sea naval mine hazards sustains great-power escalation concerns and elevates maritime commodity logistics risks.
  3. Houthi Missile Threat and Regional Strike Capabilities45Potential Russian intelligence support for Houthi targeting prolongs threats to commercial shipping lanes and elevates regional security risk premia.
