Notes from the Trenches // Closing the loop
Seven calls resolved against falsifiers I wrote in advance. The two worst misses share one root: an explanation I published before I had tested it. The January stablecoin drop is where I ran the test properly, and it is still only partly explained.
Between January 24 and February 25, 2026, I published seven pieces on tokenized assets, stablecoins, custody and market structure. Each carried a falsifier, a sentence written in advance that says what would prove the call wrong. A forecast without one is a mood. This is the accounting, and I did not rewrite the falsifiers after the fact.
A word on terms, since I will use them. A stablecoin is a token pegged to a currency, here the dollar. USDC (USD Coin) is one, issued by Circle. USD1 is another, issued by World Liberty Financial. RWA (real-world asset) tokenization means putting claims on things like Treasury bills onto a blockchain. The SEC (Securities and Exchange Commission) is the United States securities regulator.
The first piece forecast that about 62% of a roughly $35B tokenized real-world-asset market would become structurally vulnerable in the first quarter and migrate to compliant rails. Distributed RWA value on the tracker rwa.xyz read $38.8B on October 5. There was no collapse, and I record that call as missed on its headline.
The falsifiers resolved cleanly. The confidence I attached to the calls did not deserve to travel with them.
One more thing on the ledger: two of the pieces carried an in-house "S-TIER" grade, and their central premise failed on a read of the primary text. I no longer cite those grades. A score you assign yourself measures your own patience.
Read the scorecard again and the two worst misses are not independent. The custody cascade failed because I built it on a reading of a regulator's statement. The USDC "recovery" falsifier fired because I set the baseline from memory. Both were explanations written before the test, in the voice of a finding. That is the pattern, and the rest of this piece is that pattern put under a microscope on the one question where I have enough public data to do it.
The explanation I published started with the highest credence on my list and ended with the lowest.
On February 1 and 2, two pieces said the SEC staff statement of January 28 classified tokenized Treasury bills and DeFi wrappers such as wrapped staked ether (wstETH) as non-compliant, and that institutions were dumping stablecoins in response. I gave that story a credence of 0.55 when I started testing it, the highest of any explanation I held.
The first test took an afternoon. I read the statement twice, with a word search. It restates that securities law applies on-chain and sorts tokenization into three kinds: issuer-sponsored, third-party custodial and third-party synthetic. It does not name Treasury bills. It does not name wstETH. It does not name wrappers. The credence fell to 0.15 on that read alone.
The tripwire hit on the date and missed on the content. A cascade built on a document that does not say it has no trigger.
I defined USDC "recovery" as a return to about $80B. The December level was $75B to $77B: $75.3B on December 31, $75.2B by February 28, with a $79.6B peak on March 17 (DefiLlama). Against the real baseline my own falsifier had fired, and my first draft of this post read a September snapshot and missed it. Once I measured the baseline and the recovery, the regulation story fell to 0.05.
The size of the January move is also a range for a dull reason: the two data sources disagree by about $1B on some days, and one of them stamps its daily points at 00:00 UTC, a day off from events. Part of the move may be measurement.
USDC supply fell about $5.7B to $6.6B between January 15 and January 31, depending on the source: DefiLlama shows $76.7B to $70.1B, CoinGecko $75.7B to $70.0B. USDC, bitcoin and Solana all peaked on January 15 and 16, so supply turned with the crypto cycle at its high, not with a headline. The statement that I blamed came twelve days after the turn.
The campaign is a leading suspect with its own caveat, not a finding.
Peak to trough, January was -9.2% over 14 days, and USDC regained 95% of its prior peak 12 days after the low. The Silicon Valley Bank episode in March 2023 was -26.9% over 39 days with no recovery in the window. The Stream collapse in November 2025 was -2.9%. A fast V is how a demand-for-liquidity episode looks, and a trust shock does not rebound that way. The shape argues against forced institutional selling and leans toward the deleveraging and macro readings.
A credence is my subjective probability that a factor contributed more than about 10% of the move. They overlap and do not sum to one.
The explanation I had barely considered, the exchange campaign, moved the most. Empty results count too. Each of these had a falsifier written in advance and none found its effect: the October 10 cascade (it hit a different stablecoin, and USDC rose afterward), a rotation into Solana (it lost USDC too), the Iran war (it began February 28, six weeks after the largest drops), sanctions (the designation targeted a different coin, a day later), foreign selling of Treasuries (foreigners were net buyers), credit stress (spreads near year lows), hacks (about $370M in January, mostly not USDC), and a backtest of a synthetic-dollar depeg against USDC supply. Weekly correlations with bitcoin, bill yields, spreads and the dollar never cleared a multiple-comparison bar after more than a dozen tests, so a couple of borderline hits is what chance would give.
I also left some stories out of the causal account on purpose. Stories about pardons, officials' business ties, an adviser's holdings and an executive's dispute with World Liberty are alleged or disputed in what I could source, and for each I found no flow link to USDC supply. They carry no weight here. Silence counts as evidence in this method only for required, routine disclosures.
The deciding question is whether the USD1 mints were funded by USDC redemptions. Two things could answer it: a list of USDC burns by entity from a paid on-chain analytics vendor, and Binance conversion data for the campaign window. Until then the account stays at two legs and one open thread, which is where the record puts it.
The same rule applies to me. I have registered, before computing anything, a scoring test of whether my early explanations run overconfident: a Brier score, the average squared gap between a stated probability and what happened, on the calls that stated a probability and on the priors above. The registration is not blind, since I have read both ledgers, and no score exists yet. If the test says my early explanations run hot, that goes in the next post.
The unproven part stays marked unproven. That is the whole discipline.
The rule for the next calls: name the falsifier first, read the primary text twice, and correct in public when a number is wrong.
