The Blockade

The people who matter most already know you love them. But they'd still like to hear it today.

Twenty-one hours of face-to-face talks in Islamabad produced no deal. Hours later, President Trump announced an "effective immediately" US Naval blockade of the Strait of Hormuz, threatening to interdict every vessel that paid Iran's toll. US intelligence confirmed China is preparing to ship air defense systems to Iran within weeks.

Markets minute

The S&P rallied to 6,840 while systematic positioning sits at 3.3 out of 10, the widest price-conviction gap in years. BTC's 3-month basis collapsed to 2.10%, speculative leverage evaporating while institutional infrastructure scales underneath. Brent futures and physical crude are diverging by $36-40 per barrel, paper pricing a disruption, physical pricing a crisis. Gold near $4,800 with the 10Y frozen at 4.29% is the regime tell: hard assets become the consensus when both rates and growth deteriorate simultaneously.

Today's signals
Trump's Blockade Doesn't Open the Strait. It Closes It Under a Different Flag. Twenty-one hours of talks in Islamabad collapsed. Hours later, Trump announced a US Naval blockade of Hormuz, interdicting every vessel that paid Iran's toll and threatening 50% tariffs on any country assisting Iran. Here is what the coverage misses: the blockade doesn't reopen the strait. It adds a second layer of restriction on top of Iran's mines. Before the war, 130-160 tankers transited daily. Under Iran's toll system, a trickle got through at 3.24 per day. Under the blockade, potentially fewer, because US interdiction imposes conditions Iran's toll didn't. Trump isn't trying to open the strait. He is trying to transfer control of it. Same chokepoint, different gatekeeper. Iran goes from toll collector to besieged state. The IRGC warned that approaching military vessels "will be dealt with harshly and decisively." A leaked Iranian survey commissioned by President Pezeshkian's office shows 92% internal dissatisfaction with the ruling system, the highest since the revolution. Whether the regime can prosecute a military confrontation while facing that level of domestic opposition is the question no analyst is asking. The ceasefire expires April 22. If both the blockade and Iran's toll system operate simultaneously, the strait enters a dual-authority closure no diplomatic framework has addressed. The Brent futures-physical gap already sat at a record $36-40 per barrel before this. Convergence happens upward, not down.

The CPI Split That Breaks the Fed's Decision Tree March CPI revealed the starkest core-energy divergence in two decades. Core came in benign at 2.6% year-over-year, below forecast. Energy exploded 10.9% month-over-month, the largest surge since 2005. Gasoline alone jumped 21.2%. The demand economy is weakening (core below forecast, consumer sentiment at a 74-year low), which argues for cuts. Supply-driven inflation is running hot, which argues for holds. Rate cut odds surged to 85% for June after the core print, priced before Sunday's escalation. Meanwhile, Kevin Warsh's Fed chair confirmation hearing has been delayed indefinitely. Powell's term expires May 15. If the hearing slips past late April, the Fed could lack a confirmed chair during the most complex policy environment since Volcker. The committee is running a decision tree built for a world where energy shocks are transitory. When Hormuz processes 3 tankers per day instead of 130, that assumption fails.

The Quietest Pro-Crypto Two Weeks in History The CLARITY Act's stablecoin yield compromise is finalized with Senate Banking Committee markup targeted for late April. The compromise prohibits yield on stablecoin balances that mimics bank interest while preserving DeFi protocol independence. FinCEN and OFAC's proposed rules classify stablecoin issuers as "financial institutions" under the Bank Secrecy Act, not money services businesses, a critical distinction that reduces compliance burden. Alabama and West Virginia are signing DUNA Acts alongside Wyoming. Combined with the SEC innovation exemption and GENIUS Act implementation, this is the most concentrated pro-crypto regulatory progress in any two-week period in US history. It is crystallizing while every headline is about oil. Senator Moreno warned if it doesn't advance by May, crypto legislation may not get serious consideration again for years. The regulatory trifecta is real, and most of the market hasn't noticed because Iran is absorbing all the oxygen.

Anthropic Is Two Months From Overtaking OpenAI in Enterprise The Ramp AI Index, published in partnership with the Financial Times, shows Anthropic grew from 24.4% to 30.6% of businesses on its platform in a single month. OpenAI dropped to 35.2%. The gap narrowed from 11 points in February to 4.6 points, suggesting crossover by May or June. Among VC-backed firms, the early adopter cohort that leads broader market behavior, Anthropic already leads 66% to 59%. Enterprises "shrugged off" the DoD security designation, evaluating on capability rather than narrative. Meanwhile, SemiAnalysis called GPT-5.4 "just not better," and Google released Gemma 4 under Apache 2.0, running near-frontier quality on a consumer GPU for free. If Anthropic's crossover materializes by June, it reprices the entire AI competitive landscape: pre-IPO valuation anchors higher, OpenAI's growth narrative weakens, and enterprise procurement shifts from single-vendor to multi-model.

The AI Layoff Pattern That Isn't a Layoff Pattern Atlassian cut 10% of its workforce (1,600 employees) in March to "self-fund" AI investments, with over 900 of those roles in software R&D. Block did the same before it. These aren't revenue-driven layoffs. They are targeted headcount reductions redirected into AI tooling and automation. CEO Cannon-Brookes said what most executives won't: "It would be disingenuous to pretend AI doesn't change the mix of skills we need or the number of roles required." The restructuring produced $225-236 million in charges. The pattern is specific: not broad cuts from revenue weakness, but surgical R&D trims funded into AI infrastructure. If three or more S&P 500 tech companies announce similar restructurings during Q2 earnings, expect senior software engineer compensation to compress 10-15% by year-end as supply exceeds demand for the first time in two decades.

Interesting things

Dragonflies See Colors That Shouldn't Exist in Their Eyes

Dragonflies detect deep red light edging into near-infrared using a visual protein strikingly similar to the one in human eyes. The same molecular solution to the same optical problem, arrived at independently across 300 million years of divergent evolution. When nature converges on identical solutions twice, the solution space is smaller than we assumed. Convergent evolution is a signal that a solution is structurally optimal, not historically contingent.

The Housing Cycle Just Turned While Nobody Was Watching

Housing permits bottomed at 1,330 in August and recovered to 1,455 by December. New home sales went from 639 in July to 764 in November. This is happening while consumer sentiment sets 74-year lows. EPB Research's framework: the residential housing cycle moves in the same order every time, and the leading indicators have already turned. If permits sustain above 1,400 through Q2, homebuilder equities lead the broader market by 6-9 months. That is historically the trade of the cycle.

The meditation
The first principle is that you must not fool yourself, and you are the easiest person to fool.
Richard Feynman, Cargo Cult Science

There is a belief you are carrying right now that you hold not because you examined it, but because it is comfortable. Your brain is optimized for coherence, not accuracy. Today, pick one belief you feel certain about and spend ten minutes looking for the strongest case against it. If you find something and feel resistance, that is the most important information you will encounter today.

The Einstellung Effect
A known solution blocks the discovery of a superior one. Chess masters shown an unusual board position find the conventional good move first and stop looking, unable to see the better option. The more expert you are, the faster the match fires, the less likely you are to keep searching. When the situation looks 90% like something you have seen before, that 10% difference is where the Einstellung hides. Ask: am I solving the problem in front of me, or the closest problem I have solved before?
