Digital Credit

The Rothschild analogy

Michael Saylor, executive chairman of Strategy, frames Bitcoin-backed credit as the third act of a pattern that runs through financial history: gold was capital for centuries, but the mechanism that actually mattered was not gold settlement, it was gold-backed credit. The Rothschilds created the first gold-backed notes, central banks followed, and sovereign debt, mortgages, and consumer credit all ran on gold-backed paper for hundreds of years. The world was built on gold, but it ran on gold-backed credit. His extension: Bitcoin is digital gold, the world will be built on Bitcoin, and it will run on Bitcoin-backed credit, digital credit.¹

Conservation of volatility

The underlying mechanism is closer to signal processing than to traditional finance. A volatile, high-return asset carries more variance than investors who want stability actually require, so rather than asking every investor to ride the full swing, Strategy separates them into two pools. Credit investors receive a smooth, predictable slice, roughly an 11% yield. Equity investors absorb the excess volatility in exchange for greater upside. The volatility does not disappear, it gets redirected: Bitcoin, at roughly 30% expected annual appreciation, amplifies into MSTR common stock at a higher expected return and higher volatility, and compresses into STRC preferred stock at a lower, steadier yield.

The key design choice is a variable, rather than fixed, dividend. A traditional bond that promises a fixed coupon must pay it regardless of how the underlying asset performs, and a missed payment trips covenants that can force bankruptcy. A variable preferred lets the issuer reduce the dividend in a bad period instead of defaulting, which removes the forced-refinancing trigger while still paying investors more than a fixed alternative on average.

The tax mechanism

Because Strategy holds a capital asset rather than generating ordinary taxable earnings, dividends paid to STRC holders are classified as return of capital rather than ordinary income. Investors owe no tax on receipt; instead their cost basis in the security steps down, and once basis reaches zero, further distributions become capital gains, with a full step-up in basis at inheritance. Over a 20-year compounding scenario, Saylor's own comparison has $100 in short-term treasuries producing about $3.75 a year of income for an heir, against roughly $922 of principal and $100 a year of income from the same amount compounded in STRC, a difference he attributes largely to the tax treatment rather than to yield alone.

The five instruments

Saylor has named a full family of Bitcoin-backed preferred instruments. Strike (STRK) is a senior preferred paying an 8% perpetual dividend with a hundred-year option to convert into common equity. Strife (STRF) is a senior perpetual preferred yielding roughly 9% effective, structured to match Bitcoin's own infinite holding horizon: borrow forever, invest in Bitcoin forever. A junior, non-cumulative preferred (STD) trades below par at roughly 12.5% effective yield, stripped of governance protections in exchange for a higher rate. Stream is the euro-denominated equivalent of Strife. Stretch (STRC) is a monthly variable preferred targeting a stable $100 par value at roughly 10.8% effective yield, designed as something close to a one-month Bitcoin treasury bill for investors who want maximum simplicity.¹ Saylor has also described the entire family as designed with AI assistance: "it's a hundred times better than a good preferred stock... It was designed completely with AI."²

Volatility, by the numbers

Saylor has given explicit volatility figures across the stack: Bitcoin itself carries a measured volatility around 45 with an expected five-year annual return near 50%; MSTR common stock carries volatility around 65 with an expected return near 75%, absorbing more than its share of the swing; and STRC strips volatility down to around 7. He describes the underlying engineering directly: strip Bitcoin's volatility from roughly 45 down toward the low single digits, extract a yield several points above the risk-free rate from the stripped instrument, and the result is a credit product with an unusually high Sharpe ratio for a fixed-income instrument, "we're really engaging in financial engineering to distill pure currency yield above the risk-free rate."² The addressable market he points STRC at is not other Bitcoin products but the roughly $30 trillion sitting in treasuries and money market funds earning about 4% in taxable income, against which a several-billion-dollar STRC issuance is a rounding error with a great deal of room left to grow.

Performance, and what remains outside this stack

Through a 45% Bitcoin drawdown from its all-time high, STRC held its full principal value while continuing to pay its stated dividend, a real-world stress test for an instrument only months old at the time. A related idea from the same keynote, BTC yield, describes what happens when Strategy issues credit against a portion of its Bitcoin holdings each year and uses the proceeds to buy more Bitcoin: at a 10% annual issuance rate, Bitcoin held per share of the company roughly doubles every seven years, a compounding effect that runs independently of Bitcoin's own price appreciation.¹ The model's central risk is that its assumptions about Bitcoin's expected appreciation are load-bearing: at a lower assumed growth rate, credit issuance capacity and yield levels shrink substantially.

CZ draws a useful line between this structure and a different, still largely unbuilt one. Saylor's instruments convert Bitcoin volatility into yield for capital that already exists, sold to investors who already hold dollars. CZ points at the opposite flow, credit extended to crypto users who need capital they do not have, which he calls the largest missing category in the industry: "loans is a very small portion of crypto markets. That's a huge area that's not in crypto yet."³ Both gaps are real; only the second remains largely unbuilt.

The open-network alternative

Paul Frambot's Morpho represents the opposite governance pole of the same underlying move, a credit layer forming above a new capital substrate. Where Saylor's stack is one company engineering preferred instruments against a single appreciating collateral asset, Morpho is a permissionless network where lender-set terms clear against a widening set of on-chain collateral, with trust flowing through the network rather than through a single issuer's balance sheet.⁴ Both reject the same defects in legacy credit markets, tax inefficiency, terms that favor the issuer, and retail inaccessibility, but Saylor solves it by building a better issuer, while Frambot solves it by removing the issuer and letting trust flow through an open network instead.
