Developed Markets (EFA): Erosion, a Crowded Haven and a Clipped Wing
Why Dimon's dollar warning describes erosion more than collapse, why Big Tech's haven status is fragile, and how an EFA broken-wing butterfly fits.
Time, Leverage and Bad Habits
When the chief executive of America's largest bank starts talking about cracks in the bond market and a reserve currency on its way out, my first instinct is to ask what the speech is for. Banks are quarterly animals. They struggle to see past the next earnings call, so a forecast stretching decades into the future deserves a raised eyebrow. The deficits are real. The shape of the ending is where I part company. Empires rarely detonate. They leak. The leak gets a policy name: financial repression, inflation running a little hotter than officially admitted, capital controls sold to the public as prudence and stability. That is how a reserve currency actually ages, by erosion spread across years.
The dollar keeps its throne as long as the alternatives look worse, and Europe, China and Japan are all carrying debt loads that make the American balance sheet look tidy by comparison. Dominance ends only if enough capital concludes the game is rigged: foreign holders of Treasuries weary of underwriting deficits, domestic savers noticing that suppressed yields and inflated assets are the bill they have been paying. As for the enemy within, I would look past the party badges toward a machine hooked on short-term fixes, one that talks tough while quietly inflating away commitments it cannot honour. Time, leverage and bad habits do the work that invading armies used to.
Cash Piles Dressed as Bunkers
Against that backdrop the market has gone back to treating US Big Tech as the place to hide. The case has merit: deep cash reserves, earnings that hold up, and an AI story roaring back to life, with some funds reporting record weekly net buys in the leading chip designers. Corporate margins have stayed stubbornly fat as well, credited to cost cutting and pricing power by some, to lagging rate and wage effects by others.
For an options trader a crowded haven has its own signature. Long-duration assets reprice hardest when rates jump, so the names that soothe a portfolio can become the source of the storm. The letter's warning about sudden valuation pressure translates, in options terms, into a reason to keep some convexity on the table rather than renting all of it out for premium.
A Butterfly With One Wing Clipped
The position in this issue is built on EFA, the developed-markets ETF. I call it the Wavered Trumped. Held to expiry it resolves into a broken-wing butterfly, the familiar tent with one side pushed out further than the other, so the risk leans deliberately toward the side I am prepared to be wrong on. The interesting part happens before expiry. A few days in, the structure behaves less like a static payoff diagram and more like a live instrument buoyed by the dividends the underlying carries, and it wants watching.
A structure like this on an index ETF is a quiet way to express the erosion thesis: it favours a market that drifts and grinds, and it defines in advance what a sudden lurch can cost. Nothing about it requires the prophecy to come true. It only requires the market to keep behaving like an ageing empire, which is to say slowly.
Chip Prints and a Wavering Cartel
The calendar that matters starts with second-quarter earnings from the chip designers pulling in those record inflows. Confirmation keeps the rally fuelled; a wobble there shakes the haven trade with it. A further spike in yields is the second trigger, the one that turns defensive growth into a valuation problem.
Energy is the other thread: OPEC+ keeps wavering on production targets, and drone incidents and regional flare-ups keep risk premiums twitching. A disruption hands energy stocks a short-term gift; an oversupplied market caps any rally. Underneath it all sit the slow variables, whether Treasury buyers keep showing up and whether margins hold near their records. Cracks in a bond market arrive quietly, as prices that stop making sense, one at a time.
What came of it
I closed this trade, on EFA, on 13 June 2025, after 11 days, at +12% on the capital at risk.
