Hedge Fund Crude Oil Long Positions Rise to May Highs as Iran Tensions Boost Energy Risk Premium

Hedge funds pushed Brent crude net longs to 261,435 lots — the highest since May — as renewed US-Iran military conflict reignited fears of a Strait of Hormuz shutdown, while diesel and gasoline longs hit multi-month highs in tandem.
What are fund managers betting on?
In the week to September 1, money managers added 37,837 net long lots in Brent on ICE Futures Europe, lifting the total to 261,435 lots — the highest since May.
On the US side, CFTC data showed US crude net longs also climbed to their highest since June.
This means → Large money is adding long exposure on both major crude benchmarks at once — a clear, aligned directional signal.
Why the sudden surge?
The trigger: US airstrikes on Iran and Iran's retaliatory strikes on US military bases, directly stalling efforts to restore normal shipping through the Strait of Hormuz — the chokepoint for roughly 20% of global seaborne oil.
Iran resumed targeting transit vessels, reversing the gradual recovery in strait traffic.
After Iran fired missiles at Jordan, Kuwait, and Bahrain, Israel warned it would strike Iranian civilian infrastructure if attacked by Tehran — raising the spectre of a fresh military escalation across the region.
In plain terms = the world's most important oil-shipping bottleneck is being squeezed by active conflict, and supply could snap shut again at any moment.
Why are refined products rallying harder?
Diesel net longs rose to their highest since March; US retail diesel hit a record $5.85 per gallon on Thursday.
This means → Two simultaneous war fronts — the Middle East and Ukraine — are squeezing diesel supply at the refining stage, a tighter bottleneck than crude itself.
Gasoline net longs jumped to 89,263 lots, the highest since last December. Seasonally, that is the largest long position on record for this time of year, and gasoline prices sit at a September all-time high.
Can this long trade last?
Positioning data shows the market's pricing of geopolitical risk is still deepening, not a one-off spike.
The key variable is singular: whether the Strait of Hormuz situation de-escalates in a meaningful way.
In plain terms = as long as the strait is under fire, longs have a reason to stay; the moment shipping truly normalises, these positions will be unwound fast.
