Bitcoin Treasury Drawdown Stress-Test Methodology

Test	Question	Principal boundary
Static reserve floor	At what Bitcoin loss does reserve value reach the floor?	No timing, liquidity friction, or financing dynamics
Dated cash schedule	Can each obligation be funded when due?	Depends on credible inflows and asset access
Collateral stress	When do contractual margin or liquidation conditions apply?	Uses the actual contract rather than a universal threshold

C is accessible cash, B is initial Bitcoin market value, and F is a fixed reserve-value floor, all in one currency. Drawdown d is a loss fraction from zero to one. The simplified case holds cash and the floor constant and assumes unencumbered Bitcoin can be valued without transaction costs.

A broader stress test adds revenue reductions, operating outflows, debt dates, collateral terms, and restricted assets. It also separates committed financing from funding that merely might be available. Market liquidity and operational access can fail together.

For the static reserve case:

• V(d) = C + B × (1 - d)
• Headroom(d) = V(d) - F
• Crossing threshold d_star = (C + B - F) / B, when B > 0

If C + B < F, the floor is already breached. If C + B = F, there is no downside headroom. If C > F, no loss up to 100% of Bitcoin breaches the floor in this restricted model. If C = F, full Bitcoin loss reaches the floor exactly. If B = 0, a Bitcoin drawdown threshold is undefined; compare cash with the floor directly.

Equality reaches the floor. A breach is V(d) < F if that strict convention is used. A contractual rule may instead trigger at equality, so the boundary matters.

For dated liquidity, cash_t = cash_t-1 + inflows_t - outflows_t. Minimum cash headroom = min(cash_t - required cash floor_t). A negative result identifies a shortfall in the specified schedule, even if year-end total assets appear adequate.

With hypothetical C = 60, B = 40, and F = 80, d_star = (60 + 40 - 80) / 40 = 50%. A 50% Bitcoin fall leaves reserves of 80. A 70% fall leaves 72, or a shortfall of 8 relative to the floor. The example establishes neither a probability of such a fall nor a legal insolvency conclusion.

The static calculation is a reserve sensitivity, not proof of cash availability. Selling Bitcoin converts an asset into cash but does not restore total asset value by itself. Sale costs, taxes, price impact, settlement delay, and collateral restrictions can reduce accessible proceeds. A rule that all operating cash remain untouched may create a different trigger than the total-reserve floor.

A collateral test follows the loan's valuation basis, eligible collateral, haircut, cure period, and liquidation terms. A generic loan-to-value ratio cannot represent every agreement. Stress scenarios also need a sequence: a payment before an asset sale can fail even when the same amounts balance over the whole period.

Missing debt maturities, pledged balances, or restrictions prevent a complete survival conclusion. A blank field is not an absence of obligations. A scenario based on dated statements remains a scenario for that balance sheet; new financing or acquisitions can invalidate it without any Bitcoin price change.

The static threshold excludes operating losses and access constraints. More detailed forecasts still depend on uncertain revenues and execution. Historical maximum drawdown is not the maximum possible future decline. A high threshold can coexist with fraud, custody failure, or a cash shortage that the chosen equation does not represent.

Name the constraint before quoting a survival threshold. Total reserve value, spendable cash, and collateral headroom can fail at different times, so one percentage cannot stand for all three.
