Dear Diary: The S&P Just Hit 7,000 and There's a Naval Blockade
Dear Diary: The S&P Just Hit 7,000 and There's a Naval Blockade
April 17, 2026
Let me walk you through the week's most important number. Not 7,022. Not $95 Brent. Not the IMF's 3.1% global growth forecast, revised down from a world that no longer exists. The number is one-fifth.
One-fifth of the world's oil and gas — every drop of it — flows through a 21-mile-wide channel between Iran and Oman. The Strait of Hormuz. You probably knew that already. What you maybe haven't fully processed is that the US Navy is sitting in that channel right now, blockading Iranian ports, while the ceasefire technically holds and the S&P 500 is at an all-time record high. These two facts are co-existing in the same universe. This week, on the same Wednesday, traders celebrated the index crossing 7,000 for the first time in history while the IEA called the supply disruption the most severe oil shock ever recorded. The floor of the New York Stock Exchange was apparently fine with this.
We are, as a civilisation, very committed to the bit.
The IMF dropped its World Economic Outlook on Monday. The title is Global Economy in the Shadow of War, which is the kind of phrase you'd usually see on a history textbook, not a live policy document. Chief Economist Pierre-Olivier Gourinchas stood at a podium in Washington and explained that the fund had been preparing to upgrade its global growth projections — the economy had real momentum, around 3.3% — and then the war happened. Now the reference forecast is 3.1% for 2026, with headline inflation rising to 4.4%. The adverse scenario gets you to 2.5% growth and 5.4% inflation. The severe scenario, where energy supply disruptions extend into next year, starts to rhyme with concepts economists prefer not to use in public.
Four times since the year 2000 has global growth fallen below 2%. Each time, we called it something. The GFC. COVID. The others. The IMF is now formally stress-testing a scenario where we find ourselves there again, not from a financial crisis, not from a pandemic, but from a naval standoff over a nuclear program in a 21-mile strait. The fund's document describes three channels of transmission: higher energy and food prices, persistence in wage and price inflation, and — this one deserves its own sentence — a confidence shock. Confidence is doing a lot of work in global finance right now. Someone should check on it.
Meanwhile, the equity market has developed a curious coping mechanism: it has decided the war is nearly over. Every piece of diplomatic noise out of Islamabad or Washington gets immediately discounted into risk assets. Brent eases slightly. The Nasdaq rips. The Nikkei added 2.43% on Thursday, led by tech. The S&P notched its longest Nasdaq win streak since 2009 in the same week that Iran's military command called the US blockade a ceasefire violation.
This is not irrationality, exactly. Markets are forward-looking, and the forward they're looking at is one where talks resume, a deal gets done, oil comes off, and the Fed — still frozen at 3.50%-3.75% with the dot plot pencilling in one cut and seven officials wanting nothing — eventually gets room to move. It's a coherent thesis. It requires the ceasefire to hold. It requires Iran to accept some version of a nuclear deal. It requires the Lebanon front to stay contained despite Netanyahu explicitly carving it out of the Iran agreement. It requires a lot.
Delta Air Lines already blinked. CEO Ed Bastian said this week the carrier would "meaningfully reduce" near-term capacity growth due to jet fuel costs. That's not a geopolitical forecast. That's a balance sheet reacting to a world where Brent at $95 is the relieved price — down from the $102 it hit when the blockade began. The airlines always see it first. They always say it plainest. The rest of the market is running a different model.
There is a version of this that ends fine. The version Wall Street has priced. Talks resume. A framework emerges. Oil slides back into the low eighties. The ECB hikes once in June, the Fed cuts once in Q4, global growth settles at 3.1% — anaemic by historical standards, survivable by political ones. Goldman hits another record quarter. The S&P grinds to 7,200 by December. We write retrospective pieces about how the market's resilience in April 2026 was actually a buying signal and everyone who panicked was wrong.
There is also a version where the severe scenario in that IMF report is not a tail risk but a base case. Where the confidence shock Gourinchas mentioned at his podium is not a variable in a model but a lived experience in credit markets. Where the ECB hiking into a slowing European economy is the policy error everyone discusses in 2028. Where Brent at $95 is the floor, not the ceiling.
The market is pricing version one. The IMF is publishing version two as a stress test and calling it severe. Somewhere between those two documents is the actual future, and nobody — not the Fed, not the fund, not the desk running the Hormuz scenario in whatever quant shop you care to name — has a confident read on which way it breaks.
What's certain is that the Strait is still blockaded. The war is still live on one front even if paused on another. The IEA's language — most severe oil supply shock in history — is still sitting on a server at rue de André Pascal, uncontested. And the S&P 500 closed this week above 7,000 for the first time ever.
Remarkable times. Possibly the wrong reaction to them. We'll find out.
History doesn't announce which version it chose until it's already done choosing.
