The Houthi movement has declared a naval blockade on Saudi Arabia, raising the stakes for global energy supplies and shipping routes in the Red Sea region.
The declaration marks a significant escalation in the ongoing conflict, with potential implications for oil flows and freight costs.
Markets are reacting to the heightened risk, with Brent crude prices climbing as traders price in the possibility of supply disruptions.
The Strait of Hormuz, a critical chokepoint for global oil shipments, remains under threat, with shipping firms already offering hazard bonuses to crew members transiting the area.
US Secretary of State Marco Rubio has reiterated Washington's readiness to negotiate with Iran, signaling a diplomatic effort to de-escalate tensions.
However, the immediate impact on energy markets is likely to persist as long as the blockade threat remains active.
