The Optionality of a Bitcoin Treasury
The treasury owns Bitcoin by default. Everything else is a financing choice, a liquidity buffer, or a trade against future residual sats.
Strategy is not a dollar treasury
A dollar-denominated treasury naturally rests in dollars, T-bills, and working-capital cash. A Bitcoin treasury rests in BTC. Dollars are held because they must be held: dividends, debt service, taxes, redemptions, settlement timing, and a reserve that keeps the credit stack calm.
That means cash is never neutral. Even when the cash is in T-bills, the drag is the assumed BTC CAGR minus the after-tax reserve yield. Sometimes that drag is worth paying because it prevents a worse forced trade. Sometimes the timing works in the treasury’s favor. But the cost has to be named in sats.
Do not mix the failure model with the going-concern model
Failure path
If the company fails, seniority and liquidation preference control the waterfall. In that model, liquidation price matters because it determines who gets paid first.
Going-concern path
If the company keeps operating, the cost of a preferred is not its liquidation price. The cost is the present value of future dividends measured in BTC under stated assumptions.
Atomic reconciliation
Physical funding can come from ATM proceeds, reserve cash, a BTC sale, or a mix. The atomic ledger still asks how many sats the cash use consumed and whether residual sats improved.
Every treasury move has an accretion test
| Trade | Accretive when | Dilutive or dangerous when |
|---|---|---|
| Cash/T-bills → BTC | Expected BTC return exceeds reserve yield after taxes and the liquidity reserve remains adequate. | Near-term dividends, debt service, redemptions, or market-access risk make the cash buffer more valuable than the BTC upside. |
| BTC → Cash/T-bills | Liquidity, discounted liability retirement, tax timing, or reserve quality prevents a larger future loss. | It creates idle dollar exposure without a dated use; the drag is BTC CAGR minus cash yield. |
| Common → BTC | ATM proceeds buy more sats per new diluted share than existing shares already have, after fees. | Common trades below the accretion threshold, so issuance lowers sats per diluted share. |
| BTC → Common | A buyback retires common claims for fewer sats than those claims represent after senior obligations. | Common trades at a premium that costs more BTC than the residual claim retired. |
| Preferred → BTC | The BTC bought exceeds the BTC present value of dividends and senior claim risk, with authorization and liquidity gates satisfied. | Coupon, discount, cadence, or trigger risk consumes the BTC raised before common receives residual upside. |
| BTC → Preferred | A repurchase retires a senior claim at a large enough discount or removes a destabilizing obligation. | The treasury spends scarce BTC to retire a claim near fair value while losing optionality and liquidity. |
| Common → Cash/T-bills | High-premium issuance funds a reserve or a dated liability transaction that protects residual sats. | The cash has no dated use and sits as negative carry against BTC. |
| Cash/T-bills → Common | Common trades below residual sats per share and the reserve remains strong after the buyback. | The buyback weakens the reserve or pays a premium for junior claims. |
| Preferred → Common | Preferred proceeds cost less in BTC PV than the common residual claim retired by a buyback. | It adds senior claims to retire junior claims at fair value or a premium. |
| Common → Preferred | High-premium common issuance retires preferred at a discount or removes expensive dividend/trigger risk. | Common is issued below the accretion threshold or the preferred is retired near fair value. |
| Cash/T-bills → Preferred | The discount captured plus avoided future dividends beats the BTC opportunity cost of using cash. | The reserve is reduced for a weak discount while BTC opportunity cost remains high. |
| Preferred → Cash/T-bills | Temporary reserve funding prevents forced selling or funds a dated higher-return capital action. | Senior capital is raised and then parked in cash without a use, creating negative carry. |
Optionality is only valuable when the exercise test is explicit.
The book builds these conditions from primitives, then applies them to Strategy’s public filings.
