Why did crude fall while the Strait of Hormuz stayed shut?

On Thursday 13 August WTI settled at $81.25, down 2.43%, and Brent at $87.07, down 2.15% — handing back a six-session run that had carried Brent up 12.0% from its 5 August low. The strait did not reopen on that day. Both things are true, and reconciling them is the work.

The reconciliation this brief can defend is that two legs of the same conflict are being priced as separate durations. The ceasefire leg is marked at 0.984 through the weekend — effectively settled, and therefore no longer a source of movement. The closure leg is the one still repricing, and it is repricing in the horizon rather than on the front page. We named that regime 'de-linked: war premium fading, closure premium accruing'.

Conviction is deliberately split here: medium-high on the de-linking, which is measured rather than inferred, and low on flat price, which is not. A view on the structure of a market is not the same thing as a view on its next print.
