Hormuz is moving 5% of its usual oil traffic. Brent at $100 still prices in a quick fix.
ICE Brent front-month is above $100, yet the Strait carries just 5% of normal volume and the MoU's survival is far from assured.
ICE Brent crude front-month crossed $100 per barrel early Friday (2026-07-24), its highest level since the U.S.-Iran conflict erupted, having surged above $91 in Asian trade on Monday (2026-07-20) before pulling back through the session as fresh U.S. strikes on Iran and Iranian targeting of American bases and vessels in the Strait of Hormuz added a new layer to the standoff.7,6
The intraday fade that followed the Monday (2026-07-20) spike has become a pattern. Traders have used each escalation — including Brent's $2.74 gain to $86.04 on Tuesday (2026-07-14) — as a selling opportunity, betting the memorandum of understanding signed weeks earlier between Washington and Tehran would hold and that shipping disruptions would prove temporary.4,1 That trade has not aged well.
What the episodic fading is obscuring is the physical severity of what is already in place. Reporting from mid-July described the Strait of Hormuz operating at just 5% of its usual capacity. The U.S. Energy Information Administration recorded approximately 20 million barrels of crude oil and petroleum products per day transiting the Strait in 2024, representing about 20% of global petroleum liquids consumption. At 5% throughput, the implied interruption to a chokepoint with no viable alternative routing is near-total.5,6
Markets have not ignored this. Brent jumped 5.4% to $85.58 in a 24-hour window in mid-July, and hedge funds substantially increased their exposure to crude around that time.5 But $85 to $100 is not $85 to $180, which is where Rystad Energy's head of geopolitical analysis put the potential ceiling in the event of acute re-escalation and prolonged Hormuz blockage.2 The distance between the current spot price and Rystad's projection implies the market is still assigning substantial probability to a near-term resolution.
That assumption rests heavily on the MoU surviving. Citi said in a research note that the probability of Iran abandoning the memorandum before the U.S. midterm elections has increased, a scenario in which oil prices could remain elevated for an extended period.4 The political calendar matters because it constrains both parties' diplomatic flexibility. Washington is unlikely to offer significant concessions in the weeks before a domestic vote; Tehran has limited incentive to concede before it understands the post-election U.S. posture. The U.S. decision to revoke sanctions waivers on Iranian oil exports has narrowed the economic benefits Iran might gain from compliance.3
The second factor markets appear to be underweighting is less dramatic but arguably more durable: depleted inventories and damaged infrastructure do not reverse the moment a ceasefire is signed. Energy analysts flagged this as early as Thursday (2026-05-28), noting that traders were balancing diplomatic optimism against long-term concerns about inventory depletion and damaged port infrastructure — and that was before the July escalation.1 Tanker routing diversions, elevated insurance costs, and loading disruptions compound over weeks. A headline-driven settlement closes the political chapter; the physical supply deficit it leaves behind does not vanish within a trading session.
JKM front-month was at $21.82 per MMBtu early Friday (2026-07-24), reflecting the exposure of Asian importers dependent on Gulf shipping lanes. The transmission from a Hormuz constraint through Dubai and Urals grades before reaching European benchmarks typically takes weeks to propagate fully, which means the complete cost of the current interruption may not yet be visible in forward markets.
The contrarian case resolves if shipping data from the Strait recovers materially from the 5% throughput figure reported in mid-July — toward 40% or higher — or if Iran signals a credible return to the diplomatic track before the U.S. electoral calendar forecloses that option. IMF PortWatch transit data for Hormuz will be the clearest early indicator. If throughput does not recover, the gap between $100 and the Rystad ceiling may prove narrower than current pricing assumes.5,2
