Iran War Halts Oil Flows; Saudi Output Lowest Since 1990, Strait of Hormuz Traffic Down 30%

The Iran-Israel conflict has triggered the most severe energy supply shock in decades. According to the EIA, crude oil and fuel flows through the Strait of Hormuz fell by nearly 6 million barrels per day in the first quarter of 2026, representing a nearly 30 percent decline in one of the world's most critical chokepoints. This supply destruction has cascaded into global energy markets, pushing crude prices sharply higher and forcing central banks and investors to reassess inflationThe rate at which prices rise across an economy. trajectories.

Saudi Arabia's crude oil production has collapsed further in recent weeks, with the kingdom reporting output at the lowest level since 1990, according to an OPEC submission. The combination of direct conflict impacts (disruptions at export terminals, shipping lane insecurity, refinery damage) and market-driven production cuts by OPEC members seeking to support prices has created a perfect storm of supply tightness. North Sea oil has begun trading at a discount for the first time during the Iran war, a sign that even premium grades are losing pricing power as the market absorbs the supply shock.

The macro implications are severe. Higher energy costs are filtering through the global supply chain, evident in the uptick in producer prices and the need for firms to stockpile goods ahead of further price rises. Developing economies, particularly those that import most of their fuel, face the sharpest margin pressures. Pakistan's economy accelerated in the last quarter despite the conflict, but observers note that higher crude prices are a near-term headwind.

Fitch Ratings downgraded Bangladesh's outlook to negative, citing high vulnerability to the Middle East conflict.

Energy importers globally face rising input costs that will either compress margins or force price increases onto consumers. Farmers and transporters are already reporting pressure from fuel surcharges, and automotive maintenance costs have risen due to oil-linked input costs. Conversely, energy exporters and companies with exposure to oil and gas services stand to benefit. Oil-linked currencies (RUB, SAR, AED, KWD) are steady to stronger. The US is using the conflict as a geopolitical tool, with reports that a Chinese-owned supertanker is testing a US blockade of the Strait of Hormuz; outcomes here could further tighten supplies or relax them, depending on US policy enforcement.
