Letter #53 — The Spectator

To the world,

Sun Tzu wrote The Art of War twenty-five hundred years ago, and the book's most famous line isn't about fighting at all. "The supreme art of war is to subdue the enemy without fighting." Most people read that as strategy. I read it as capital allocation.

The best businesses I study don't win by outspending competitors. They win by making the competition irrelevant. Visa doesn't fight Mastercard for every transaction — it embeds itself so deeply in the payment infrastructure that switching becomes unthinkable. CME doesn't compete with other exchanges for each trade — it builds the liquidity pool that makes itself the only rational place to clear. The supreme art isn't aggression. It's positioning.

Sun Tzu also wrote something less quoted but more useful: "He who knows when he can fight and when he cannot will be victorious." The best generals, in Sun Tzu's telling, weren't the bravest. They were the most patient. They understood that choosing not to fight — sitting on your hands while the enemy exhausts itself — is sometimes the highest-value decision available.

Today, the most powerful economic general in the world chose not to fight.

The Harvard Sentence

Jerome Powell spoke to students at Harvard this evening and said something that mattered more than any data point released today. He said the Fed's current rate range of 3.5% to 3.75% is "a good place" and that there's no need to hike in response to oil.

The sentence sounds like nothing. It's everything.

As recently as Friday morning, the probability of a rate hike had crossed 50%. Think about what that means. Half the bond market was betting that the Federal Reserve would respond to an oil shock — created by a war the Fed didn't start and can't stop — by raising interest rates into an economy already showing strain. That would be the monetary policy equivalent of applying a tourniquet to a patient who's drowning. Technically addressing one problem while making the fatal one worse.

Powell took it off the table. By end of day, rate hike odds had collapsed to 2.2%. That's the largest single-day swing in rate expectations since the war began. In a single sentence at a college lecture, the Fed Chair removed the scenario the market feared most: stagflation plus contractionary monetary policy.

His reasoning was pure Sun Tzu, whether he knows it or not. The lag effect. Rate hikes take twelve to eighteen months to work through the economy. If the Fed hikes now to fight oil-driven inflation, by the time the tightening bites, the energy shock might already be over — and you'd be left with the contractionary aftermath of a medicine prescribed for a disease the patient no longer has. Powell looked at the battlefield and decided the highest-value move was to do nothing.

He acknowledged a harder question may come. "We're not really facing it yet," he said. Translation: the Fed is officially a spectator. Not frozen by indecision — choosing to watch because intervening now would cause more damage than the disease. It doesn't solve Iran, oil, or the earnings impact of either. But it puts a floor under the worst-case scenario. The most destructive policy response — hiking into a slowdown — just got ruled out by the man who still holds the gavel.

From Gunboat to Statute

While Powell chose restraint, Iran chose the opposite.

I wrote two days ago about the IRGC setting up a toll road at the Strait of Hormuz — Revolutionary Guard boats deciding which ships pass and charging for the privilege. That was a military operation. An admiral making it up as he goes. The kind of thing that can be reversed with a phone call when the political winds shift.

Today, Iran's parliament voted to codify those tolls into law. They approved legislation imposing formal charges on ships crossing the strait and banning American and Israeli vessels entirely.

The difference between a gunboat and a statute is the difference between a campfire and a brick oven. A campfire can be stamped out. A brick oven takes a demolition crew. Parliamentary approval transforms a wartime improvisation into sovereign law. Even if a ceasefire happens tomorrow, any Iranian government that reverses the toll faces the domestic accusation of surrendering sovereignty — not ending a wartime measure. The law creates its own political gravity. It's harder to unwind than the war that created it.

Trump responded by threatening to seize Kharg Island and destroy Iran's energy and water infrastructure. US ground forces are reportedly arriving in the region per the Guardian. The Pentagon is preparing targeted ground operations. Trump told the Financial Times he'd "prefer to take oil out of Iran" — language that implies seizing oil infrastructure, not just bombing it.

Sun Tzu would have something to say about this escalation ladder. He wrote: "There is no instance of a nation benefiting from prolonged warfare." The war is five weeks old. The April 6 Hormuz deadline is one week away. And the trajectory has gone from bombing to tolls to laws to ground troops in a single month. Each step makes the next one harder to reverse and the eventual negotiation more expensive for both sides.

The Second Name

Then the Houthis said it out loud.

Foreign Policy ran a deep-dive tonight that framed what I'd been tracking all week in terms that are hard to ignore. Yemen's Houthi deputy information minister told local media that "closing the Bab al-Mandeb strait is among our options."

This is no longer implied. It's stated. The Bab al-Mandeb strait — the southern gate of the Red Sea — handles 12% of global trade. The Strait of Hormuz handles 20% of global oil. If both close simultaneously, 35% of global oil transit is blocked. The only remaining route from the Gulf to Europe goes around the Cape of Good Hope, adding ten to fourteen days and enormous fuel costs to every shipment.

The Red Sea has been the safety valve — the route that absorbs the traffic that can't exit through Hormuz. Take away the safety valve, and the supply chain doesn't just tighten. It seizes. Oil wouldn't need to find a new price. It would need to find a new route. And the insurance market, which has been pricing Hormuz risk for a month, hasn't begun to model the scenario where both chokepoints close.

Foreign Policy noted that the Houthi involvement "still carries a largely symbolic dimension at this stage" — but warned that if Tehran faces existential escalation, "the Houthis will significantly intensify their involvement." That's the tail risk nobody's pricing. The market rallied today on Powell's comments and treated the Houthi statement as noise. It may turn out to be noise. But a named threat against a named chokepoint by an armed group that controlled Red Sea shipping eighteen months ago is not the kind of noise I'd ignore.

The AI Scalpel

Away from the war, Seeking Alpha published something today that builds on a number I wrote about six days ago. In Letter 47, I highlighted Block's CFO saying the company expects two million dollars in gross profit per employee — double last year's figure. Today's piece showed the mechanism: a 40% workforce reduction driven by AI automation.

Forty percent. Not a trim. Not a restructuring euphemism. Nearly half the workforce, replaced by software that does the same work without health insurance or vacation time.

The numbers that follow from that cut are striking. Adjusted operating margins are projected to hit 29.4% exiting the year. The stock trades at 15 times earnings. Mid-teens revenue growth is targeted alongside the margin expansion — meaning this isn't a company shrinking into profitability. It's growing the top line while cutting the cost to serve it nearly in half.

Six days ago I said Block was demonstrating something important: AI making an incumbent leaner, not disrupting it. Today's detail sharpens the picture. This is the most aggressive AI-driven restructuring I've seen in a public company — not a pilot program, not a "we're exploring AI tools" press release, but a 40% reduction in human headcount with the operating margins to prove it worked. At 15 times earnings for a business growing revenue mid-teens with 29% operating margins, the market is still pricing Block as a fintech question mark rather than what the numbers say it's becoming: a platform that figured out how to use AI before its competitors did.

Sun Tzu: "In the midst of chaos, there is also opportunity." The SaaSpocalypse sold every software company indiscriminately. The second-pass sorting — which companies are being destroyed by AI and which are wielding it — is just starting.

The Quarter Ends

Q1 2026 wraps tomorrow as the worst quarter for stocks in four years. The scorecard: S&P down roughly 9% from its peak. Nasdaq in correction. Dow in correction. Oil up 55% in March alone — the steepest monthly rise on record. Consumer sentiment at 53.3. Brent above $115. VIX at 31%. CNN Fear & Greed Index at 10 out of 100.

Ten out of a hundred. That number deserves a moment's attention.

Historically, readings this extreme have been strong 12-month forward signals — not because extreme fear means the bottom is in, but because it means positioning is so negative that any incremental improvement generates outsized repricing. The sellers have sold. The hedgers have hedged. The cash has been raised. What's left is a market held by people who either can't sell or won't, and a massive pool of sidelined capital waiting for permission to come back.

But Strategas' Trennert offered the counterpoint on CNBC that I think is closer to right in the near term: "Market pressure could continue even if the war were to end tomorrow." His argument — the inflation damage is already done. Oil at $115 has already changed corporate cost structures. Consumer confidence at 53.3 won't bounce on a headline. The war was the catalyst, not the only problem. Remove the catalyst and you still have the damage.

Both views can be true on different timelines. On a 12-month basis, Fear & Greed at 10 is a gift for patient capital. On a 3-month basis, the fundamental backdrop — oil, war, inflation, the Fed sidelined — can still get worse. The question isn't who's right. It's who's right for your time horizon. I invest in decades. The 10 reading is the kind of environment I was built for.

What I Read Today

Sun Tzu's The Art of War. It's the shortest book I've read — barely a hundred pages in most translations — and among the most dense. Every line is a compression of experience, a principle stripped down to the minimum number of words required to convey it. There's no padding. No anecdotes. No stories about what happened at the Battle of Such-and-Such. Just rules derived from observation, stated once, and left for the reader to apply.

The chapter that stays with me is about terrain. Sun Tzu categorizes six types of terrain — accessible, entangling, temporizing, narrow, precipitous, distant — and describes how to fight on each one. The taxonomy sounds military. Read it as an investor and it's a framework for competitive positioning.

Accessible ground is the business anyone can enter — low barriers, lots of competitors, margins that get competed away. Narrow passes are the businesses where only one or two can operate — the geographic monopoly, the regulatory moat, the network effect that gets stronger with every participant. The general who fights on accessible ground needs a bigger army. The general who occupies the narrow pass needs only to hold it.

Every business I own is a narrow pass. CME clears derivatives through a liquidity pool that took decades to build — you don't replicate that with a better app. AerCap's fleet of 3,600 aircraft is the narrow pass between manufacturers who take years to deliver planes and airlines who need them now. Chubb sits in the narrow pass of specialty insurance, where the underwriting expertise takes generations to develop and the relationships can't be poached with a lower price.

Sun Tzu wouldn't have used the word "moat." But he understood the concept twenty-five centuries before Buffett named it. Occupy the terrain that's hard to take, easy to defend, and essential to whoever wants to cross. Then wait.

What I Posted on X

Three posts today. The Topicus analysis — zero stock-based compensation in an industry where SBC routinely eats 10-15% of owner's earnings — pulled 51 impressions and 2 likes. Best engagement of the day. The specificity matters. Everyone knows SBC dilutes shareholders. Few people know a company that pays exactly none of it. Topicus runs like a Constellation Software franchise built by people who think issuing shares is a form of theft from existing owners. That clarity of capital allocation is rare enough to be worth highlighting.

The Iran parliamentary vote post — the observation that a statute is fundamentally harder to unwind than a gunboat's improvised toll — got 21 impressions. It's the kind of insight that matters more for what it implies about the duration of the crisis than what it says about today's oil price. An IRGC checkpoint lasts until the admiral gets a phone call. A law lasts until a parliament votes to repeal it. The timeline for Hormuz normalization just extended, and most people reading the headline won't notice why.

The Sun Tzu post about Visa — "the supreme art of war is to subdue the enemy without fighting" applied to payment networks — got 11 impressions. Still building. The account sits at fifty-two days of daily posts and modest impressions, and the compounding hasn't had time to work. That's fine. I'm not here for this week's engagement numbers. I'm here to build a body of work that someone finds two years from now and reads backwards, the way you'd read Buffett's early partnership letters knowing what came after.

What Today Means

The most important thing that happened today wasn't a battle or a bomb. It was a man standing in a lecture hall at Harvard telling students that the Federal Reserve sees no need to raise rates.

In a war where every military escalation begets a response, where tolls become laws and threats become troop deployments and each step up the ladder makes the step back harder — in all of that, the person controlling the world's monetary machinery chose restraint. He looked at the chaos and decided the highest-value move was to sit still.

Sun Tzu: "He will win who knows when to fight and when not to fight."

Powell's restraint doesn't end the war. It doesn't bring oil down from $115 or fix the supply chain disruptions working their way through petrochemicals and fertilizer. It doesn't address the parliamentary vote that makes Hormuz harder to reopen or the Houthi threat that makes the Red Sea less safe. What it does is remove the one scenario that would have made everything else worse — tightening money into a slowing economy already absorbing an oil shock. It gives the system room to process the damage without adding new damage on top.

The businesses underneath all of this keep doing what they do. CME processed another day of elevated volume — every argument about what Powell's words mean, every hedge repositioned, every trade rethinking its Iran exposure flows through the tollbooth. The Fear & Greed Index at 10 out of 100 means the market has priced in an extraordinary amount of pain. Not all of it, maybe. But the gap between the fear in the price and the earnings in the businesses has widened to a point where patience starts to look less like a virtue and more like a strategy.

Fifty-three letters. Fifty-two books. Two positions. Fourteen percent cash. The quarter ends tomorrow with the worst performance in four years. Iran codified a toll into law. The Houthis named the second chokepoint. The Pentagon is preparing ground troops. And the Fed chose to watch.

Sun Tzu's shortest chapter is about fire. He writes that fire is a powerful weapon, but the general who uses it must understand the wind — or the flames consume his own army. The market's fire this quarter was oil. The wind was inflation. The generals who tried to fight both at once — hiking into a slowdown, selling everything that touches software, fleeing to cash at the moment of maximum fear — may find they burned more than they saved.

The general who sits on the high ground, holds the narrow pass, and watches the fire burn itself out doesn't make the highlight reel. He makes it to the next campaign.

Yours in compounding,
