Institutions Calm BTC Volatility in 2025 by Selling Covered Calls
In 2025 institutional investors significantly reduced Bitcoin (BTC) market volatility by using derivatives to generate yield from idle spot holdings. Key volatility gauges—the Volmex BVIV and Deribit DVOL 30-day annualized implied volatility—fell from about 70% at the start of the year to near 45%, touching a low of 35% in September. The primary driver was widespread selling of out-of-the-money covered calls by entities holding BTC or spot Bitcoin ETFs, producing steady premium income and increasing options supply that pressured implied volatility. Market participants also observed a persistent put skew across expiries—puts trading at a premium to calls—reflecting hedged long positions rather than outright bearish sentiment. Industry voices cited include Imran Lakha (Options Insights) and Jake Ostrovskis (Wintermute), who noted that over 12.5% of mined Bitcoin sits in ETFs and treasuries, creating an incentive to harvest yield via option overwriting. For traders, the decline in implied volatility implies cheaper option premiums, smaller expected short-term moves in BTC prices, and greater likelihood of option-seller strategies performing well.

Neutral
The news is market-neutral overall. Institutional selling of covered calls reduces implied volatility and mutes short-term BTC price swings, which benefits option sellers and lowers option premiums—this is constructive for income-focused strategies but not directly price-bullish. Put skew (puts trading at a premium) signals that institutions are hedging long exposure, indicating conviction in long-term holdings rather than an active bearish stance. Historically, periods where large holders harvest yield (e.g., option overwriting by ETF holders) have correlated with lower realized and implied volatility without producing sustained price rallies; they can support stability and compress trading ranges. Short-term implications: reduced volatility means fewer large intraday moves, making volatility-based trades less attractive and favoring premium collection strategies (selling calls, iron condors). Liquidity in options markets may improve, tightening spreads. Long-term implications: sustained institutional adoption and hedged long positions can underpin market stability and reduce tail-risk, but they also cap upside during rallies because covered-call selling puts systematic pressure on upside. Traders should monitor IV indices (BVIV, DVOL), put/call skew, ETF flows, and open interest to time option strategies. Similar past episodes include periods after major ETF inflows when option overwriting increased and IV fell, producing stable price action rather than strong bullish breakouts.
