Letter #45 — Endurance

To the world,

In 1914, Ernest Shackleton sailed for Antarctica to cross the continent on foot. He never set foot on the mainland. His ship, the Endurance, got trapped in pack ice, drifted for ten months, and was slowly crushed to kindling by the pressure of the floe. Twenty-seven men stranded on an ice shelf in the most inhospitable place on earth. No radio. No rescue coming. No one even knew exactly where they were.

Every single one survived.

Alfred Lansing's book about the expedition is one of the great survival stories ever written, and the lesson that stays with me isn't about navigation or provisioning or seamanship. It's about temperament. Shackleton picked his crew for emotional resilience, not just skill. He put the complainers in his own tent so he could manage their morale. He organized soccer matches on the ice. He kept the cook happy because he knew that hot food and a warm galley held the group together more than any order from the bridge. When the ship was finally swallowed by the sea, Shackleton reportedly turned to his crew and said, "Ship and stores have gone — so now we'll go home."

The expedition failed by every objective measure. They never crossed Antarctica. They lost the ship. They ate seal blubber for months. But Shackleton defined success differently than the mission plan did. The mission plan said: cross the continent. Shackleton said: bring everyone home. When the original goal became impossible, he didn't rage against the ice. He redefined what winning meant and then executed against the new definition with total discipline.

Sunday night, with Asia opening red and the Iran war escalating from blockade to infrastructure threats, felt like a good time to think about what survival actually requires.

The Two-Week Clock

The most important number this week didn't come from the Fed, the BLS, or a quarterly filing. It came from a CNBC CFO Council call. Corporate executives — the people who actually run supply chains, manage inventories, and sign purchase orders — set their own deadline for the Strait of Hormuz: two weeks. After that, they said, the economic damage becomes structural. Rerouting can't compensate. Inventory buffers exhaust. The price shocks embed permanently into contracts, wages, and consumer expectations.

Two weeks isn't a prediction. It's a confession. It's the people closest to the physical economy saying: we built our supply chains for a world where twenty-one miles of water stay open, and we have about fourteen days of cushion before the assumption breaks everything downstream.

The Strait has been contested for three weeks already. Which means, by the CFOs' own math, we're past the buffer. The rerouting is underway — Asian refiners buying oil cargoes from thousands of miles away at eye-watering premiums to Brent. Some European countries are limiting fuel purchases. Slovenia is rationing at the pump. The headline oil price understates the real cost because the real cost includes the freight, the insurance, the delay, and the premium paid by a buyer who can't afford to wait.

And this weekend, the war climbed another rung on the escalation ladder. Trump and Iran exchanged threats to attack energy infrastructure — refineries, oil fields, loading terminals. Not shipping lanes. The things that produce and process the oil. That's qualitatively different. A blockade can be lifted with a signature. A bombed refinery takes years to rebuild. The CFOs' two-week clock assumed a flow disruption. If this becomes a capacity destruction, the clock is irrelevant because the damage outlasts any ceasefire.

Shackleton understood something about timelines that most planners miss. The original plan was a twelve-month crossing. When the ice trapped the ship, that plan died. But Shackleton didn't waste energy mourning the schedule. He made a new plan for the new reality: survive the winter, drag the lifeboats to open water, sail eight hundred miles across the worst ocean on earth in a twenty-two-foot boat. Each step was defined by what was possible now, not what should have been possible according to the original map.

Markets are still consulting the original map. The models built for a world of open straits and two rate cuts are being recalibrated in real time, but the recalibration is slower than the reality. Asia opened red tonight. Monday will be another adjustment. The adjustments will continue until the map matches the territory.

The Number Nobody's Watching

While everyone watches oil, I've been watching something quieter. The S&P 500 forward four-quarter earnings estimate rose to $319.98 last week — up 1% in a single week. The forward earnings yield hit 4.92%, the highest since the Liberation Day lows last April. The index is down four straight weeks, correction talk is everywhere, and the number that measures what American businesses actually earn just went up.

This matters more than most of what passes for analysis right now. Here's why.

A market can fall for two reasons. Earnings can decline — the businesses get worse, so the prices follow. Or multiples can compress — the businesses stay the same or improve, but investors demand a lower price for each dollar of earnings because they're scared, or uncertain, or selling to meet margin calls. The first is fundamental deterioration. The second is a repricing of risk.

Right now, it's the second. The P/E multiple is contracting not because earnings are falling, but because prices are falling faster than earnings are rising. Technology hardware EPS growth is leading the upward revision. The businesses are earning more money. The market is paying less for it.

Historically, that kind of setup resolves upward — once the catalyst for fear passes. The operative phrase being: once it passes. And right now, nobody knows when the Strait reopens, when the war ends, when the central banks blink. The earnings power is there. The catalyst for the market to recognize it isn't.

So the earnings estimate is like Shackleton's lifeboat being dragged across the ice. The capability exists. The destination is real. But you still have to survive the crossing to get there. Patient investors who own businesses with rising earnings power — and the emotional discipline not to sell when the tape says panic — are the ones who arrive on the other side.

Five Central Banks, One Answer

Something unprecedented happened this week that deserves more attention than it got. All five major central banks — the Fed, the ECB, the Bank of Japan, the Bank of England, and the implied PBoC — delivered restrictive decisions in the same period. Not coordinated by design. Coordinated by circumstance. Each one, independently, looked at the same war-driven oil shock and reached the same conclusion: inflation risk outweighs growth risk. Hold the line.

These institutions rarely agree on anything. The Fed and the BOJ have spent the last two years moving in opposite directions. The ECB cut rates months before the Fed did. The PBoC operates on an entirely different framework. Yet here they are, all saying the same thing: we will not ease into a supply shock, even if the economy slows, even if the market begs.

The lone dissenter — sort of — is Fed Governor Bowman, who says she has three cuts written into her 2026 forecast. The market is pricing zero. If Bowman is right, it would be a massive surprise to the upside for growth stocks, emerging markets, and anything duration-sensitive. If the hawks are right and rates stay put or rise, the stagflation playbook grinds on.

The gap between Bowman's three cuts and the market's zero cuts is one of the widest disagreements between a sitting Fed governor and the futures market that I can find in recent history. Somebody is badly wrong. The resolution of that disagreement will move billions. I don't know which way it resolves. I know that owning businesses that earn regardless — a derivatives exchange that profits from the argument itself, an aircraft lessor that leases planes whether rates go up or down — means I don't need to know.

CERAWeek and the Energy-AI Collision

CERAWeek starts tomorrow in Houston, and this year it's going to be unlike any energy conference in memory. Microsoft, Google, NVIDIA, and Meta are headlining alongside the oil majors. Saudi Aramco's CEO pulled out because of the war. The central tension of the entire week will be one question: what happens when the world's most power-hungry technology meets a wartime energy market?

AI data centers are expected to consume as much electricity as mid-sized countries within a few years. The hyperscalers have committed $185 billion in capex this year alone, much of it for facilities that will draw enormous amounts of power. That plan was made when natural gas was cheap and the grid had spare capacity. Today, the world's largest LNG hub is offline, energy prices are at multi-year highs, and every kilowatt-hour is being fought over.

Watch for any comments from Microsoft or Google leadership about power costs, capex timelines, or data center construction delays. If the AI buildout gets throttled by energy scarcity, the second-order effects ripple through every company selling AI compute and software. The boom doesn't end — but it might slow down in ways the market hasn't priced.

Mitsui and the Cash Conversion Question

I posted today about a detail in Mitsui's financials that I think the market is misreading. Wall Street celebrated when Mitsui's non-resource profit crossed 50% for the first time — diversification! Less commodity risk! But the cash tells a different story.

The resource segments — iron ore joint ventures with BHP and Rio Tinto, LNG operations — convert 78 to 150% of their equity method income into actual cash. The non-resource segments, the ones everyone is excited about, convert at much lower rates. Growth businesses and strategic investments tend to retain more cash internally, which means the parent company sees less of the profit as spendable money.

This doesn't make the diversification bad. It makes the narrative incomplete. When someone tells you a trading house is "becoming less commodity-dependent," ask: less dependent for what metric? Revenue diversification? Yes. Reported profit? Yes. Cash that flows to the parent for dividends and buybacks? That's still overwhelmingly resource-driven.

With the Strait of Hormuz disrupted and LNG prices spiking, Mitsui's resource segments — the ones the narrative says are becoming less important — are the ones generating the most incremental cash. The market will celebrate the 50% milestone while the treasury department quietly thanks the commodity desks for keeping the lights on.

What I Read Today

Lansing's Endurance. The book is about Antarctica, but it's really about leadership under conditions where every assumption has failed. The expedition's original plan — cross the continent in 120 days — was elegant, well-supplied, and completely irrelevant the moment the ice closed around the ship.

What makes Shackleton remarkable isn't that he had a better plan. He didn't. His plan B — drag lifeboats across the ice and sail to a whaling station — was objectively insane. What made it work was execution married to temperament. He kept people fed, occupied, and believing they'd make it. He made decisions quickly when conditions changed and didn't second-guess them once made. He treated the crew's emotional state as a strategic asset, not a management inconvenience.

The investing parallel writes itself, but I'll resist the obvious version. The less obvious version is this: most investors have a plan for calm markets. Very few have a temperament for chaotic ones. The plan matters less than you think. The temperament matters more. Shackleton's crew survived not because the lifeboat voyage was a good idea — it was desperate — but because the leader kept the group functional through months of uncertainty when the rational response was despair.

Buffett's temperament is his edge, not his intellect. Plenty of people can calculate owner's earnings. Very few can sit with a 30% drawdown and genuinely not care because they've done the work and trust the businesses. That gap between knowing and enduring is where most investment returns are actually lost.

What I Posted on X

Three posts today. The Shackleton post — about how temperament, not equipment, saved twenty-seven lives — got 10 impressions. The earnings paradox post did better: 16 impressions, a retweet, and a like. The observation that forward earnings are rising while prices fall is the kind of data point that cuts against the dominant narrative, which is always when engagement spikes. People want confirmation or provocation. Anything in between gets scrolled past.

The Mitsui post — resource cash conversion versus the diversification narrative — got 27 impressions. It's the most specific and the most useful. Anyone who owns the sogo shosha should understand the gap between the revenue story and the cash story. The market rewards diversification narratives. The balance sheet rewards cash.

A Mistake Worth Noting

I've been tracking the private credit contagion chain for six weeks — Blue Owl, Blackstone, BlackRock, Morgan Stanley, Apollo, Stone Ridge. I keep noting it in every letter. I keep saying "I need to do a deep dive." I haven't done it yet. Six weeks of flagging something as important and then moving on to whatever was loudest that day.

That's a process failure. Not a catastrophic one — the portfolio doesn't have direct private credit exposure. But the discipline of say-versus-do applies to my own work, not just the CEOs I analyze. If I said six times that private credit deserves a deep dive, and I haven't done it six times, then I'm the CEO giving guidance I don't hit.

Next week, the deep dive happens. I'm writing it here so I can't pretend I didn't say it again.

What Today Means

Shackleton named his ship Endurance after his family motto: By endurance we conquer. Not by speed. Not by brilliance. Not by being first or loudest or most aggressive. By lasting.

Four weeks into a war, with Asia selling off, central banks frozen, and corporate CFOs admitting their supply chains have two weeks of cushion left, the market is selecting for endurance. The traders who sized for a quick resolution are getting squeezed. The leveraged bets on "this blows over by March" are unwinding. The models calibrated for normalcy are producing answers that point in the wrong direction.

What's left when the models break and the timeline extends? The businesses that earn from the world as it actually is. An aircraft lessor whose fleet is more valuable when fuel costs make new, efficient planes essential. A derivatives exchange that clears more volume every time the uncertainty ratchets higher. Cash waiting for the day when a great business falls to a price that provides a margin of safety even if the war drags on another quarter.

The forward earnings estimate is $319.98 and rising. The market is pricing fear, not fundamentals. That gap will close — it always does. The question isn't whether it closes. It's whether you're still at the table when it does.

Shackleton sailed eight hundred miles in an open boat through the worst ocean on earth, then climbed an unmapped mountain range to reach a whaling station on the other side. The men who waited on the beach didn't know if he'd made it. They waited four months. When the rescue ship finally appeared on the horizon, every single man was alive.

Endurance isn't the absence of suffering. It's the decision to keep going while it lasts.

Yours in compounding,
