The global energy order is fracturing as tensions in Iran disrupt oil flows and reshape geopolitical dynamics. The blockaded Persian Gulf and OPEC fragmentation have shifted market priorities from economic efficiency to political alignment. Resource nationalism, once rare, now defines supply chains, with nations prioritizing sovereignty over global trade rules.

The U.S. fossil fuel dominance has intensified as Washington leverages its energy self-sufficiency to pressure adversaries. Meanwhile, Iran’s war-driven export collapse—down 70% year-on-year—has created supply shocks, pushing oil prices above $90 a barrel. OPEC’s inability to coordinate output cuts amid internal divisions underscores the group’s weakening influence.

Market volatility has surged, with Brent crude fluctuating 15% in weeks. Analysts warn that geopolitical risk premiums may persist, complicating long-term investments in energy infrastructure. Non-OPEC producers, like the U.S. and Russia, are filling gaps but lack OPEC’s coordinated pricing power.

Investors face uncertainty as energy market volatility becomes the new norm. Policymakers must navigate a world where oil flows are weaponized, and economic interdependence erodes. The breakdown of the post-WWII energy order signals a return to Great Power competition, with far-reaching implications for global stability.
