Greg Foss is back. After stepping away from Twitter and spending time on Nostr, the veteran credit analyst explains what pulled him back: young people reaching for socialism, and credit markets he sees as far less healthy than equities. The credit default swap thesis. Foss walks through his method: take the CDS spread on U.S. government debt, multiply by total obligations including unfunded liabilities, then compare that to Bitcoin's market cap. He flagged his spread number as from memory. Why insurance, not a risk asset. Most holdings are short volatility: when volatility rises, they fall. Foss argues Bitcoin should do the opposite, and credits BlackRock's Larry Fink as one of the few in traditional finance framing it that way. The rate the Fed does not control. Warsh has suggested AI productivity gains leave room to cut. Foss points instead to the 10-year Treasury, set in the open market, which could rise if investors demand more for U.S. credit risk. Credit markets are flashing before equities. A listener asked about widening CDS spreads across AI infrastructure names. Foss compared NVIDIA's vendor financing to Nortel and Lucent in 2000, and pointed to CoreWeave's tight debt service covenant. Banking is a leveraged business. From inside an insolvent Bank of Boston in 1992, Foss saw the math up close: roughly $5 of equity behind every $100 loaned. He argues Bitcoin can act as a safety net against that fragility. Bitcoin mining versus AI data centers. Miners can switch off in seconds and chase stranded energy; AI workloads cannot. Suze raised UK curtailment spending and ERCOT's grid balancing record, and asked whether mining gets built into AI sites. What the ETFs changed. Foss says a Wall Street wrapper was necessary for institutional allocation, while raising the paper Bitcoin question. He runs a 5% of global assets thought experiment, stressing he is not certain it happens. Treasury companies as an evolution, not an endpoint. Foss says he admires Michael Saylor without admiring every lever pulled, notes the premium to underlying Bitcoin has collapsed toward parity, and expects these vehicles to matter less over time. Bitcoin as collateral, and pensions inching in. Foss calls Bitcoin pristine collateral and a natural extension of lending. Dom described recommending it to pension boards years ago and pointed to a Michigan 13F filing adding to its position.
