Nobody actually blockaded the Strait of Hormuz. The tankers just stopped showing up — which, if you own oil, is the same thing. The ceasefire ended the way these things do, with ordnance: Iran hit commercial ships in the Gulf, including an LNG tanker, the U.S. answered with a second night of strikes on Bandar Abbas and Sirik and kept Iran's export license revoked, and Iran lobbed one back at Bahrain and Kuwait. Roughly 20% of the world's oil squeezes through that waterway, and insurers don't wait for a formal "closed" sign — Rystad Energy told the Journal traffic has essentially stopped. Here's the tell I love: U.S. crude inventories actually rose 3 million barrels, the first build in eleven weeks, and oil ran up anyway. More supply, higher price. That's not a shortage, that's a fear premium — and fear premiums can pack up and leave as fast as they arrive.
The sharper move was one rung downstream. The Kremlin banned diesel exports, U.S. diesel futures popped 11% in a day and are now up 72% on the year, and the refiners — who buy crude and sell the product — printed money on the spread. Marathon Petroleum (MPC) and Valero (VLO) both punched 52-week highs, which is the most seductive chart in the business: a stock at its high, a headline that explains exactly why, momentum waving you aboard. And that's precisely the one I pass on. This is where portfolio hedging earns its name — the whole point of an energy sleeve, anchored in the boring bluechips like Chevron (CVX) and Exxon Mobil (XOM), is that you own it before the scare, so on a day like this part of the book is working while the front page melts down. As a general planning principle, a hedge you buy after it spikes isn't a hedge, it's a bet. When the insurance pays, the disciplined move is to trim the winnings back into the rest of the plan — not to chase 52-week highs on war news and double your coverage at the top of the panic.
You don't need me to tell you a storm's coming when you can watch the tankers turning around on the radar. But the forecast isn't the point — the roof is. So while it's still just a headline, that's the day to climb up and check yours, not the day the water's already in the hallway. A review runs about 15 minutes; bring your latest statement and we'll see whether your umbrella's actually where you left it. Nothing here is a forecast or a promise — just the unglamorous math of owning the hedge before you need it.
