Pakistan and Türkiye defending Saudi Arabia against Houthi attacks, invoking the Mecca pact, risks broadening West Asia's conflict. This move could mean direct confrontation with Iran, which backs the Houthis, disrupting Saudi oil exports.

While ending hostilities benefits the oil market, the situation's escalation hinges critically on Iran's unpredictable reaction, making crude prices uncertain.
