Bearish options made up 53.5% of Bitcoin’s options volume this week

Traders loaded up on downside protection after a sharp price drop, even as longer-term open interest still leans toward calls

Bitcoin traders spent the week shopping for insurance. Bearish options accounted for 53.5% of Bitcoin’s options volume this week, according to data shared on X. The post framed the shift as a sign of institutional demand for downside protection.

A selloff, then a scramble for hedges

Bitcoin fell roughly 7.3% from a peak of $86,728 to a low of $80,394 on October 8. As of October 12, Bitcoin had stabilized in the $83,500 to $83,750 range.

That bounce did not calm the options market. For the October 16 expiry, the put-to-call ratio hit 1.43, which means puts outnumbered calls by 43%.

A put option gives the holder the right to sell at a set price, so it pays off when prices fall. A call does the opposite and profits when prices rise.

Around $451 million in notional value for those near-term puts sits at strike prices between $76,000 and $80,000.

The bigger picture still leans bullish

Total Bitcoin options open interest across platforms sits somewhere between $37 billion and $37.45 billion. Calls make up about 60% of that total. Open interest put-to-call ratios have hovered between 0.66 and 0.71, which is firmly call-leaning.

Much of that call positioning targets longer-dated strikes, such as $95,000.

Volatility and the macro backdrop

The 30-day at-the-money implied volatility ranged from 34% to 35.7% during the period. Realized volatility, which measures how much prices actually moved, came in at about 37% to 38%.

When realized volatility runs above implied, options are pricing in calmer conditions than traders have recently lived through, which can make protection look relatively cheap compared with recent price action.

Overall sentiment in the options market shifted from a calls-richer stance to a puts-bid posture. Traders have also been positioning ahead of releases like the FOMC minutes, which can move risk assets as investors parse the Federal Reserve’s thinking on rates.

What this means for traders and investors

The research points to institutional participants protecting against bearish moves rather than abandoning their longer-term view on Bitcoin.

The concentration of puts at $76,000 to $80,000 deserves attention. Large clusters of open contracts at specific strikes can become reference points that traders watch closely as expiry approaches. The October 16 expiry is the near-term date to monitor, with a put-to-call ratio of 1.43 tied to that date.

With open interest in the tens of billions, derivatives positioning is no longer a side show to spot trading. If realized swings stay elevated and implied volatility catches up, protection gets more expensive, and late hedgers pay the premium.
