Anchorage Warns Bitcoin Yield Trade Could Cap Gains If BTC Rips Higher

Anchorage Digital's research demonstrates that Bitcoin covered-call strategies can generate 4-6% annualized yields in slower markets but significantly cap upside during bull runs. The study of 37,000+ backtests reveals the strategy requires active management with volatility and trend filters to succeed, as unfiltered approaches lose money despite favorable win ratios due to Bitcoin's autocorrelated rallies.

Anchorage Digital's comprehensive analysis addresses a critical tension in Bitcoin yield strategies that institutional investors increasingly face. The firm's research leverages an extensive dataset spanning October 2021 to April 2026, testing covered-call writing across Deribit's implied-volatility surface with mathematical rigor rarely applied to crypto options strategies. This matters because Bitcoin options have matured significantly, with notional open interest exceeding $60 billion—surpassing the entire futures market—and new venues like IBIT options democratizing access for institutions.

The research reveals Bitcoin's volatility risk premium remains 2-3 times larger than equity benchmarks, creating genuine income opportunities. However, the central finding challenges passive overlay assumptions: an unfiltered 20-delta, 30-day covered-call strategy generated negative 0.5% yields over the full cycle despite winning 57 of 70 trades. The culprit is Bitcoin's tendency toward sustained, autocorrelated bull phases where short calls get repeatedly overrun. This pattern manifested during late 2021, the 2023-2024 rally to $70,000, and the 2025 push above $100,000.

Implementing disciplined filters transforms outcomes materially. Requiring non-bullish trend conditions and elevated implied volatility, combined with 75% take-profit thresholds and gamma-risk buffers, increased annualized contributions to 5.2% over the full period. The productive corridor emerges as 10-25 delta calls with 21+ day expiries, delivering positive yields 55-100% of the time depending on timeframe. For institutional investors, this research establishes covered calls as tactical income tools for sideways or declining markets rather than permanent yield overlays, fundamentally shifting how sophisticated investors should model BTC portfolio construction.

• →Unfiltered covered-call strategies on Bitcoin lose money long-term despite high win ratios because bull-market rallies overwhelm capped upside.
• →With proper volatility and trend filters, covered calls generate 4-6% annualized yields across most rolling windows, but require active management.
• →Bitcoin's volatility risk premium remains 2-3x larger than equities, making the income attractive but path-dependent on market regime.
• →The productive strategy corridor narrows to 10-25 delta calls with 21+ day expiries; deltas below 10 are too thin and above 25 lose directional protection.
• →Covered calls work best during sideways or declining markets but leave investors watching Bitcoin rally after selling upside in bull phases.
