Yemeni government forces are battling Houthis in strategic Kahbub mountains, near Bab al-Mandeb, Al Jazeera reports

Episodes of this kind have historically transmitted to Brent and WTI through freight rates, war-risk insurance premia, and rerouting around the Cape rather than through any actual loss of supply, since Yemen itself is not a material producer. The distinction that has mattered in past escalations is between combat confined to land and attacks or credible threats against commercial shipping; the former has tended to fade from prices quickly, the latter has sustained a premium for as long as carriers divert. The actors are well established: government forces backed by a regional coalition on one side, a group with a demonstrated capability and prior willingness to target vessels on the other. The tells worth noting are any statement from the group on maritime operations, advisories from shipping authorities and insurers, and tanker tracking showing diversion patterns. Absent a shipping dimension, ground offensives of this kind have typically been a headline-risk event rather than a structural one for crude.
