Oil Prices Stabilize After Iran Sanctions Waiver Takes Effect; Time Spread Structure Weakens
Claire Weston
After Washington issued a 60-day Iran oil-sales waiver, Brent steadied near $78 — but the futures curve has already flipped toward contango, pricing in a supply surplus before barrels actually arrive.
What does the waiver actually unlock?
The U.S. granted a 60-day waiver citing "productive" Swiss talks, letting virtually any buyer purchase and pay for Iranian crude and petroleum products — including American refiners.
This means → buyers previously blocked by sanctions now have a legal pass; the barrier to Iranian oil re-entering the open market drops sharply.
Iran has already shipped over 30 million barrels in the past week. Gulf neighbors Kuwait and the UAE are also seeking alternative export routes, pushing regional supply higher overall.
Why did oil stabilize after the sell-off?
Brent traded near $78 a barrel; WTI held above $74, following a 3%+ plunge the previous session.
In plain terms = the sell-off was a one-shot repricing of "waiver plus diplomacy"; the stabilization reflects a market still waiting for verification — talks have not yet become a formal deal.
In Qatar, several empty LNG tankers transited the Strait of Hormuz openly, signaling that the chokepoint carrying roughly 20% of global oil supply is gradually reopening.
What is the futures curve saying?
Brent's front-month spread has narrowed toward flat — near-month and far-month prices are converging.
Dubai and Murban crude spreads have already flipped into contango — a structure where far-month prices exceed near-month, typical when traders expect rising supply.
This means → the market is using price structure to front-run a supply increase — the curve bent before the extra barrels showed up.
Can the diplomacy hold together?
U.S. Vice President Vance said Iran agreed to let inspectors in, but Tehran disputed the claim, denying any new commitment on inspections.
This reflects an open split on a critical issue; whether the temporary waiver can convert into a permanent arrangement remains uncertain.
Unresolved items still on the table include Iran's nuclear capability, a Lebanon-Israel ceasefire, and the secure reopening of the Strait of Hormuz.
Where could the market get it wrong?
CIBC Private Wealth managing director Rebecca Babin warned: "Crude has a habit of overshooting."
In plain terms = the market may price in a surplus before supply actually materializes — just as it priced in a shortage before barrels were actually lost.
Whether the inspection dispute can be resolved within the 60-day waiver window is the key test of whether this round of supply expectations will be borne out.
