American oil refiners are positioned to more than triple their profits as the ongoing military conflict with Iran triggers a massive boom in processing margins.

The disruption to global supply chains has created a significant arbitrage opportunity for US-based processors, who can buy crude at relatively lower prices while selling refined products at premium levels driven by scarcity fears.

This development marks a sharp divergence in the energy sector's performance during the crisis.

While integrated trading divisions of major oil companies have already recorded exceptional results from market volatility, independent refiners are now capturing the bulk of the upside.

The widening crack spreads reflect the severe bottleneck in global product availability, particularly for gasoline and diesel, as shipping routes remain exposed to geopolitical risk.

The economic winners of the four-month campaign have become increasingly clear, with defence contractors, energy firms, and investment banks all benefiting from the market upheaval.
