Strategy Inc. just showed its math on what happens if Bitcoin craters, and the answer is: not much. The company’s BTC Floor metric confirms that every single one of its debt and preferred stock instruments holds a coverage rating above 1.0x even if Bitcoin plummets to $21,000, a level roughly 80% below current prices.
The numbers behind the floor
Strategy’s BTC Floor Annualized Return, a metric the company uses to gauge the minimum performance its Bitcoin reserves need to deliver, currently sits at -11.34%. That figure represents the worst annualized return Bitcoin could deliver before the company’s obligations start looking shaky.
Put differently: Bitcoin would need to decline at roughly 11% per year, compounded over the weighted credit duration of about 5.79 years, before Strategy’s coverage ratios dip below the critical 1.0x threshold.
The company’s internal modeling goes further than the $21K scenario. Financial projections suggest the over-collateralization framework could withstand Bitcoin prices as low as $7,000 to $8,000 per coin before the math truly breaks.
On the liability side, Strategy carries approximately $6.7 billion in outstanding convertible notes following a $1.5 billion debt repurchase completed in May. Its notional preferred stock outstanding totals $15.5 billion after recent capital restructuring. Against those combined obligations, nearly 844,000 Bitcoin provides a substantial cushion.
Why the stress test matters
The BTC Floor framework is designed specifically for credit investors, the people who need to understand exactly when and how a company’s ability to service its debt might come under pressure.
The 1.0x rating at $21K means that even in a scenario where Bitcoin loses the vast majority of its value from current levels, creditors remain whole. The fact that this holds across all instruments, not just senior debt, speaks to how deeply over-collateralized the balance sheet has become.
A framework other Bitcoin treasuries might borrow
The weighted credit duration of 5.79 years shapes the entire analysis. A short-duration obligation needs Bitcoin to hold value right now. A longer-duration one gives the asset time to recover from drawdowns. By extending duration through convertible notes and preferred stock rather than short-term borrowing, Strategy has built in a temporal buffer that absorbs volatility.
The May debt repurchase of $1.5 billion also reduced outstanding obligations, effectively improving coverage ratios without requiring any additional Bitcoin purchases.
