Watched this whole thing unfold Friday into Saturday and honestly can't tell if anyone's repriced yet. Friday afternoon Iran said Hormuz was fully open. WTI cratered 10+ percent in a session. Gold held around 4878. SPX sat at record highs. Markets priced peace.
Saturday Iran walked it back. IRGC fired on an Indian VLCC carrying 2 million barrels of Iraqi crude. India summoned Iran's ambassador. 20-plus ships u-turned. Trump said the US blockade stays in full force. So the "completely open" window lasted less than a day.
So what does Monday open at? Honestly not sure anyone's confident. Friday's close doesn't reflect what happened Saturday. If your shop didn't get weekend-updates into Monday's risk book, you're starting the week marked to a ceasefire that doesn't exist anymore.
The piece I think most people are underweighting: Wednesday. That's when the whole thing expires. AP says there's an in-principle deal. A senior US official says there's no formal agreement. Both on the record, same weekend. Shuttle diplomacy running through Pakistan right now. Any Monday or Tuesday headline out of Islamabad will probably move oil 3-5 percent on interpretation alone. That's a lot of gamma for three trading days.
Secondary thing I'm watching: WSJ reported over the weekend that the US military is staging up to board and seize Iran-linked tankers in international waters. That's a real escalation from the current turn-back posture. If that happens mid-week and the ship is Chinese-owned (Rich Starry was sanctioned by the US and is owned by a Shanghai company, so it's the obvious first target), you're looking at a different class of tail risk than a pure Middle East oil premium. USDCNY, tech, defense all react to a direct US-China maritime incident.
One more thing. Energy majors lagged Friday's oil drop. XLE barely moved relative to the front-month futures. That usually means operators are pricing longer-term Iran risk, not weekly spot. If you think Wednesday goes well, XLE is a short. If you think it goes badly, XLE is already in the trade and the catch-up happens elsewhere (gold, defense, Brent calls).
Not gonna pretend I know how this resolves. Both scenarios are in the price somewhere. But the weight shifts with every headline and we get a lot of them this week.
The US military is reportedly staging to board and seize Iran-linked tankers in international waters. If the US seizes a Chinese-owned vessel, it triggers a direct US-China maritime incident, expanding risk beyond just Middle East oil. Defense (ITA) and Gold (GLD) are the catch-up trades if Wednesday's deal fails or escalation occurs. A formal ceasefire is signed and respected, deflating geopolitical premiums.
Energy majors (XLE) lagged Friday's massive 10%+ drop in WTI crude futures. This divergence means operators are pricing in longer-term Iran risk rather than weekly spot prices. If Wednesday's diplomatic deal succeeds, XLE is a prime short candidate to catch up to the downside. The deal falls apart, or the US seizes a Chinese-owned tanker, spiking oil prices.
