Bitcoin open interest adds $700M at lows as volatility builds

Bitcoin added $700 million in open interest at recent price lows, with the $60,000 put now the market's most crowded trade.

Trading volume has slumped to $2.2 billion a day this month, down from a $5.1 billion average in January, according to K33 research.

Bollinger bandwidth on bitcoin's daily chart has tightened to 5.66 points, the narrowest since January, while the 30-day implied volatility index fell to 37 percent, the lowest since May. The $60,000 put leads open interest at $1.17 billion, after the $70,000 and $72,000 calls slipped to $943 million and $888 million following Friday's $10 billion expiry.

Since 2013, a positive July has typically been followed by a negative August, with a median return of minus 7.51 percent. The concentrated put positioning at $60,000 shows traders are bracing for that seasonal pullback, and a break below the range could trigger a cascade of liquidations.

Bitcoin traded at $62,797 as of 11:07 UTC, down 3.01 percent over 24 hours, after failing to hold above $65,000. The price has been stuck between $62,000 and $65,000 for much of July, recovering from a slide below $60,000 late last month.

The $700 million in new open interest at these lows reflects aggressive leveraged positioning. If longs dominate, a short squeeze could drive prices higher; if shorts dominate, a further decline could force liquidations. Bitcoin's total open interest has held static at roughly 750,000 contracts all month, a sign traders are reluctant to deploy fresh capital in leveraged products despite the range-bound price.

The $60,000 Put Becomes the Top Trade

The options market has shifted decisively bearish. Until this week, call options at $70,000 and $72,000 were the most popular, each with $2.5 billion in notional open interest, built up ahead of the Federal Reserve's rate decision. That rally never materialized, and Friday's 08:00 UTC expiry settled $10 billion in bitcoin and ether options, unwinding those bullish bets.

Now the $60,000 put leads with $1.17 billion in notional open interest, while the $70,000 call has fallen to $943 million and the $72,000 call to $888 million. A put represents a bearish bet, and its rise to the top of the open-interest table shows traders are hedging against a decline toward $60,000.

Volatility Squeeze Points to a Breakout

The tightening Bollinger bands and falling implied volatility echo January, when bitcoin traded in a narrow $86,000-$90,000 band before a sharp move. That compression preceded a rally to nearly $98,000 by mid-January, then a slide to about $60,000 by early February. Volatility is cyclical, and prolonged quiet stretches have historically preceded sharp moves in one direction or the other.

Bitcoin's 30-day implied volatility at 37 percent has served as a floor in recent years, and since ETFs debuted in 2024 the price has shown a negative correlation with the volatility index. Any bounce in implied volatility could be accompanied by a fresh decline in spot price, making the $60,000 put level a key line in the sand.

For traders, the setup is binary. A break above $65,000 could trigger a short squeeze given the heavy put positioning, while a slide through $62,000 opens the path toward the crowded $60,000 strike, where a cascade of long liquidations could accelerate losses. The direction of the breakout is uncertain, but the calm that has defined July is unlikely to persist into August.
