1. Mechanics: The "Equity Perpetual"
Published 6/19/2026, 7:47:40 AM
MicroStrategy's (now Strategy Inc.) STRC (Variable Rate Series A Perpetual "Stretch" Preferred Stock) functions as a synthetic coin-margined Bitcoin perpetual by utilizing the company's massive Bitcoin treasury as collateral to support a leveraged equity position. While it is a regulated security (NASDAQ: STRC) rather than a crypto derivative, its mechanics—including perpetual maturity, variable "funding" (dividends), and balance-sheet leverage—mirror the risk/reward profile of a coin-margined perpetual contract.
1. Mechanics: The "Equity Perpetual"
STRC is structured as a perpetual preferred stock with no maturity date. It is "coin-margined" in the sense that its value and the company's ability to service its obligations are derived from a treasury of 713,502 BTC (as of Q4 2025).
- Collateralization: Unlike a standard perpetual where a trader deposits BTC into an exchange, STRC investors rely on Strategy Inc.'s corporate treasury.
- Liquidation Buffer: The company maintains a $2.25 billion cash reserve, designed to cover approximately 30 months of dividends, acting as a buffer against "liquidation" (insolvency) during Bitcoin drawdowns.
2. Leverage and Margin Profile
STRC provides "embedded leverage" through the company's balance sheet. It typically delivers ~1.5x to 2.5x the price action of Bitcoin.
| Metric | Value / Mechanism |
|---|---|
| Embedded Leverage | Delivers ~2x upside in rallies; experiences larger drawdowns (e.g., 62% fall vs. BTC's 38% in late 2025). |
| mNAV Ratio | Currently trading at approximately 1.1, meaning the enterprise value is 1.1x its BTC holdings. |
| Bitcoin Yield | A key performance metric measuring the % change in BTC held per share; 2026 YTD yield is 9.5%. |
| Cost Basis | Average acquisition cost is approximately $70,666 per BTC. |
3. Funding Rates (Variable Dividends)
In a traditional perpetual, funding rates are paid between traders to keep the price tethered to the spot. In the STRC model, the "funding rate" is the variable dividend paid by the company to shareholders.
- Current Rate: 11.50% per annum (as of June 2026), paid monthly in cash.
- Adjustment Mechanism: The rate is reset monthly. It cannot be lowered by more than 25 basis points per month relative to the 1-month SOFR, but there is no cap on how high the rate can be raised to attract capital.
- Cost of Carry: This 11.50% represents the cost for Strategy Inc. to maintain its leveraged Bitcoin position via equity markets.
4. Comparison: STRC vs. Crypto Perpetual
| Feature | Crypto Coin-Margined Perp | Strategy STRC |
|---|---|---|
| Collateral | BTC in margin account | BTC in Corporate Treasury |
| Maturity | None (Perpetual) | None (Perpetual Preferred) |
| Funding | Paid every 8 hours (Variable) | Paid Monthly (Variable Dividend) |
| Leverage | 1x - 100x (Exchange-based) | ~1.5x - 2.5x (Balance sheet-based) |
| Liquidation | Automatic at liquidation price | Long-term risk if BTC stays below cost basis |
Conclusion: STRC functions as a high-yield, leveraged Bitcoin play. It offers a "funding" inflow (dividends) to the holder, similar to a short position in a high-funding environment, but with the directional upside of a long position, provided the "Bitcoin Yield" and mNAV remain positive.
