Brent six-month spread hits minus 56 cents as Hormuz flows recover

Brent has moved into contango, the structure where prompt barrels trade at a discount to later-dated ones. The six-month spread turned negative on Wednesday and fell to minus 56 cents a barrel on Thursday before edging back to a slight premium on Friday. The September futures contract sat below the following five months, having first slipped to a discount to the second month last week.

The shift follows a surge in shipments through the Strait of Hormuz. Bloomberg reported that more tankers are exiting the strait, easing the supply fears that had built during the Iran conflict, while the Financial Times noted oil prices falling on expectations the chokepoint would reopen. S&P Global Platts confirmed the Brent structure flipped into contango as flows recovered. David Jorbenaze of ICIS said new crude is now chasing demand that has already been diminished, which is why near-term prices are under the most pressure.

The chart below shows Brent over the last six months, against which the move into contango can be read.

What contango means for UK buyers

Contango tells you the market sees ample near-term supply and soft demand. For UK commercial buyers, weaker prompt crude tends to feed through to softer gas and power curves, though the pass-through is partial and lagged. If you are approaching a renewal, a flatter front end can widen the gap between spot and forward pricing, which matters for how you split fixed and flexible volume.

Watch these points as the structure settles:

• Six-month Brent spread (turned negative Wednesday, back to a slim premium Friday)
• Strait of Hormuz tanker throughput and whether flows hold
• Asian demand, the swing factor SEB flags for whether contango widens
• Storage economics, viable only once contango covers 80 cents to $1 per barrel
• Knock-on movement in NBP gas and UK baseload power forwards

Contango usually rewards traders who store barrels to sell later. Nitesh Shah of WisdomTree said little incentive is needed here because inventories were drained during the conflict, so restocking can absorb some of the surplus. A European crude trader put the storage and financing cost at 80 cents to $1 per barrel for those without their own tankage, meaning the current mild contango leaves thin margins for storage plays.

Whether this is a short-lived dislocation or the start of a sustained soft patch depends on Asian demand. SEB analyst Bjarne Schieldrop noted storage opportunities will stay constrained while contango remains shallow. Buyers with flexible contracts should track the front-month spread and the Hormuz flow data through the coming fortnight before committing volume.
