Could Iran Disrupt 20% of Global Oil Flows?

As tensions rise between Iran and Israel, Alex Hodes, Director of Energy Market Strategy at StoneX, breaks down the energy market implications of potential disruptions in the Strait of Hormuz.

Key Takeaways

  • Strait of Hormuz disruption could affect 20% of global oil supply
  • Saudi Arabia and UAE have limited alternatives to bypass chokepoint
  • Potential for oil prices to reach $100 if escalation continues

Strait of Hormuz: A Global Oil Lifeline

Roughly 20 million barrels of oil per day move through the Strait of Hormuz, accounting for 20% of global supply. This makes it one of the world’s most strategically significant energy corridors. As Alex Hodes explains, “It’s a supply route for some of the major Gulf oil producers, including Saudi Arabia, the UAE, Qatar, Oman as well”.

Iranian Threats and Supply Risks

Although Iran has repeatedly threatened to close the strait, Hodes assesses that such a full closure remains unlikely. “Judging by their rhetoric… it is unlikely that this is the case,” he says. Instead, he highlights Kharg Island—a terminal responsible for 90% of Iranian oil exports—as a more immediate vulnerability.

Tanker Disruptions and Electronic Warfare

Even without a closure, there are growing signs of interference. “Overnight, there was actually a collision between two UAE tankers,” says Hodes, noting over 900 vessels in the region lost navigation signals. Tanker rates may spike, but historical precedent suggests flows won’t halt entirely.

Which Countries Are Most Exposed?

Saudi Arabia appears most exposed, sending 5.5 million barrels per day through the strait. However, they’ve built a key pipeline allowing them to divert up to 7 million barrels to the Red Sea. The UAE, exporting 3.3 million barrels per day, is also at risk but has limited rerouting options.

What If the Strait Closes?

Most producers lack meaningful alternatives. “Only the UAE and Saudi Arabia have really developed the infrastructure to avoid it,” says Hodes. In a full closure scenario, oil could “see prices back into the $100 per barrel level”.

Perspective: Morning Commentary for August 11

August 11 – It was generally a quiet night for the markets until early this morning when a headline hit that Iran and Oman were close to reaching a deal. Stock futures rallied, while the dollar index followed Treasury yields lower, along with active selling in the energy- and food-based commodities. The headline had limited impact though in a world that has become skeptical of promises of peace. Stock futures remain steady to firmer at this hour, while the VIX trades near 16 – just above 2026 lows. The dollar index is trading near 99.8 this morning, after recovering from its early morning selloff over the following hour of trade. Yields on 10-year Treasuries are trading near 4.69%, while yields on 2-year Treasuries trade near 4.22%. WTI crude oil is trading near $82 per barrel at this hour, while Brent trades near $88. The grain and oilseed markets are mostly weaker, after failing to recover from this morning’s early selloff that started in the crude oil market.

Perspective: Morning Commentary for August 10

August 10 – The world commodity markets and economy remains at risk amid two wars this morning. Tensions continue to escalate in both the Middle East and the Black Sea – risking pulling other countries into the conflicts. Stocks are down modestly this morning as we start a week of trade in which we’ll see key inflation and retail sales data following a weak jobs report this past Friday. Yet, stocks continue to trade just below record high levels, with the VIX trading near 2026 lows just above 15. The dollar index is trading near 99.7. Yields on 10-year Treasuries are trading near 4.68%, while yields on 2-year Treasuries are trading near 4.23%. The energy and food-based markets are firmer today amid the escalated risks. WTI crude oil is trading near $80, while Brent trades near $85 per barrel. Double-digit gains in the winter wheat markets lead the way for higher grain and oilseed prices.

WTI and Brent Crude Are Now Reading the Strait of Hormuz Differently

WTI and Brent crude are moving to different beats as a possible U.S. Iran deal reshapes the oil market. The two benchmarks are pricing Strait of Hormuz risk in their own ways, and the gap between them says a lot about where crude goes next.
