Bitcoin Options Markets Reveal Cautious Sentiment Ahead of FOMC Meeting

Options markets for Bitcoin heading into the September 15-16 FOMC meeting revealed a put skew, indicating traders are bracing for impact. The gap between implied volatility on 25-delta puts and equivalent calls was deliberate but not dramatic.

The 25-delta put skew for the September 25 expiry came in about 1.44 percentage points above comparable calls, according to positioning data from mid-September. This means market makers are pricing in asymmetric demand: more buyers want downside protection than upside exposure at equivalent strike distances from spot.

Bitcoin was trading near $80,000 heading into mid-September, and the broader options surface reflected cautious sentiment rather than outright panic. The DVOL index on Deribit tracked overall implied volatility around 38.9% for near-term contracts on September 16, a moderate reading not indicative of genuine liquidation spirals.

Open interest told a similar two-sided story: calls still dominated with roughly 61% of total open interest versus 39% for puts. The put skew existed because a meaningful subset of traders was willing to pay a premium for insurance on short-dated contracts specifically, pointing to event-driven hedging rather than broad structural shift toward bearishness.

The market's risk perception had shifted over the intervening months, as evidenced by the September reading representing a material step-up in defensive positioning relative to the July FOMC baseline. The duality in the data creates a complicated signal for anyone trying to predict post-FOMC price action, indicating that while traders want to be ready for a potential sell-off, they are keeping their upside exposure intact.
