Brent Term Structure Flips to Backwardation as Iran Tensions Elevate Supply Risks
Alina Collins
The Brent front-to-six-month spread hit $8.92 a barrel on Tuesday — the widest since June 10 — as the term structure flipped from contango back into backwardation, repricing near-term supply risk around the Strait of Hormuz.
What is backwardation, and why did it suddenly return?
Brent's nearest contract now trades $8.92/bbl above the six-month-out contract — the largest gap since June 10. This means → buyers are paying a premium for oil *right now*, signaling the market sees today's barrels as scarcer than future ones.
In early July, Brent sat in contango — a structure where later-dated contracts cost more, implying comfortable supply. Hormuz exports had briefly resumed and tension eased.
That structure has now reversed. In plain terms = the market shifted from "no rush" to "afraid we can't get the barrels."
Who is sounding the alarm?
Ole Hansen, head of commodity strategy at Saxo Bank, said: "A return to backwardation means the market expects crude supply to remain constrained over the coming weeks."
Neil Crosby, head of research at Sparta Commodities, noted this is still largely a paper-market move — investors re-entered bets after the latest escalation, but physical markets have not tightened in lockstep.
Crosby added that cargo flows through Hormuz are already slowing; if disruption persists, it could gradually feed into physical markets over the next few weeks.
What is the physical market showing?
Middle East crude benchmarks — Oman, Dubai, and Murban — all swung from discounts to premiums. This means → supply anxiety is not confined to financial contracts; physical buyers are bidding up too.
Kpler analysis on Monday showed tanker transit volumes through Hormuz had fallen to their lowest since May 25.
In plain terms = paper prices rising, Middle East spot premiums widening, tanker throughput dropping — three lines pointing to the same conclusion: near-term supply is genuinely tightening.
What to watch next?
The single pivotal variable: whether normal shipping through the Strait of Hormuz resumes. Early July showed that once exports recover, backwardation can unwind quickly.
If disruption persists, paper-market stress will gradually transmit into physical markets, pushing up delivered costs for Asian refiners.
This reflects a shift in crude's key driver — from demand-side dynamics to geopolitical supply risk — where price direction hinges on the situation on the ground, not on fundamentals.
