Bitcoin's Bearish Momentum and Options Market Signals: A Derivative Positioning Analysis

Bitcoin's derivatives market in late 2025 has become a battleground of conflicting signals, with bullish positioning clashing against growing bearish momentum.

This duality underscores a market in transition, where speculative bets and risk management strategies coexist.

Derivative Positioning: From Bullish Optimism to Bearish Caution

The shift in options positioning is most evident in the put/call ratio, a key barometer of market sentiment. In April, the ratio stood at 0.59, indicating strong demand for callsKey bitcoin BTC indicators are signaling a potential shift to a bearish market regime as traders await Federal Reserve Chairman Jerome Powell's remarks at the Jackson Hole Symposium^[1]. However, by June, the ratio had risen to 0.72, driven largely by cash-secured put strategies rather than outright bearishnessBitcoin's $14B Options Expiry: Put-Call Ratio Jumps as the^[2].

Such movements reflect a mix of hedging activity and yield-generation tactics, as traders lock in profits or generate income through put options.

The max pain theory further amplifies bearish signals. In August, Bitcoin's max pain level was calculated at $116,000, meaning that if the price approached this level at expiry, the largest number of option holders would face lossesBitcoin Options Expiry Dynamics: Decoding Max Pain and Put/Call ...^[4].

These levels act as psychological anchors, potentially triggering stop-loss orders or forced liquidations as expiry dates near.

Bearish Indicators: Skew, GMMA, and Macro Risks

Beyond open interest and max pain, technical indicators reinforce a bearish regime. The 180-day call-put skew on Deribit turned negative 0.42 in August 2025—the most bearish reading in over two yearsKey bitcoin BTC indicators are signaling a potential shift to a bearish market regime as traders await Federal Reserve Chairman Jerome Powell's remarks at the Jackson Hole Symposium^[1]. This skew, which measures the difference in implied volatility between put and call options, reflects heightened demand for downside protection. Similarly, the Guppy Multiple Moving Average (GMMA) has turned bearish, with Bitcoin's price crossing below the moving average bandsKey bitcoin BTC indicators are signaling a potential shift to a bearish market regime as traders await Federal Reserve Chairman Jerome Powell's remarks at the Jackson Hole Symposium^[1]. This crossover, a classic bearish signal, suggests weakening bullish momentum and potential capitulation.

Macro factors also weigh on sentiment. The anticipation of Federal Reserve rate cuts in late 2025 has led to a “sell the news” dynamic, where traders short Bitcoin ahead of expected monetary easingKey bitcoin BTC indicators are signaling a potential shift to a bearish market regime as traders await Federal Reserve Chairman Jerome Powell's remarks at the Jackson Hole Symposium^[1].

The Path Forward: Balancing Risk and Opportunity

Traders must navigate this environment with caution, balancing hedging strategies against speculative bets.

In conclusion, Bitcoin's options market in late 2025 reflects a tug-of-war between bullish optimism and bearish caution. While derivative positioning and technical indicators point to a bearish regime, macroeconomic catalysts and historical patterns add layers of complexity. Investors would be wise to monitor max pain levels, expiry dynamics, and Fed policy closely, as these factors will likely dictate Bitcoin's trajectory in the coming months.
