Ceasefire Collapses: Brent Crude Surges Back Above $85 as Hormuz Risk Returns

The clearest technical signal that traders are treating this as more than noise is in the futures curve itself. Brent flipped into backwardation this week - near-term contracts trading above longer-dated ones - for the first time in a month, a structure that specifically prices in tight prompt supply rather than just elevated average risk over the year.

Shipping data adds a physical layer to that pricing signal. Traffic through the Strait of Hormuz, which carries roughly a fifth of global oil consumption on a normal day, has fallen sharply since the latest escalation, even though some vessels are still transiting - a real behavioural response from insurers, shipowners, and charterers, not just a price move on fear.

The Bab el-Mandeb dimension turns this from an Iran-US bilateral problem into a broader Gulf supply-risk story. That strait is a critical route for Saudi Arabia's oil exports through the Red Sea, and a Houthi closure - even a threatened one - pulls a second chokepoint into the risk premium instead of just Hormuz.

For energy-importing economies, the mechanism is familiar from earlier this year: higher landed crude and LNG costs pass through to fuel prices and, with a lag of one to three months, into headline inflation. The IMF's July WEO Update had already flagged this exact channel as the reason its global inflation forecast jumped to 4.7% for 2026 - this week's price action is a live test of that forecast.

It's worth being precise about magnitude. $84-87 a barrel is elevated but still well below the peaks seen during the initial conflict escalation, when prices spiked past $100 amid fears of a full Hormuz closure. The current move looks more like a return toward those earlier crisis levels than an unprecedented risk event.

The MOU's collapse also raises a question about the durability of diplomatic de-escalation in this conflict specifically. A memorandum that held for roughly four weeks before breaking down suggests the underlying disputes were paused, not resolved - which should temper how much weight markets put on any future ceasefire announcement without enforcement mechanisms attached.
