Bitcoin derivatives volume surges as traders brace for Fed rate decision

Bitcoin derivatives trading volume climbed sharply on July 18 as institutional investors positioned for the Federal Reserve's interest rate decision later this month, with block trades on Deribit targeting a move to $72,000 by month-end.

"This week, we observed large blocks on bullish BTC call spreads," Jean-David Péquignot, commercial director at Deribit, said.

Traders executed a bull call spread strategy involving 40,000 option contracts — buying 20,000 calls at a $70,000 strike and selling 20,000 at $72,000, both expiring July 31. The structure caps maximum profit at the $72,000 level while reducing upfront premium costs. Bitcoin traded near $63,800 as of 14:30 UTC on July 18, according to CoinGecko data.

The July 31 expiry falls just 48 hours after the Fed's July 29 meeting, where fed funds futures price a 75% to 80% probability of rates held steady. A dovish outcome could propel Bitcoin toward the $70,000-$72,000 target zone, while a hawkish surprise would invalidate the setup.

The positioning comes as spot Bitcoin ETFs recorded $132 million in net inflows on July 17, while Ethereum ETFs added $36.73 million, signaling renewed institutional appetite despite ongoing market volatility, according to data from the asset managers.

Open interest across Bitcoin derivatives has expanded as traders layer in hedges ahead of the macro event. The bull call spread structure — buying an out-of-the-money call while selling a higher strike to finance the premium — reflects a measured, buy-the-dip approach rather than speculative euphoria, traders said. By capping gains at $72,000, professional investors minimized exposure to time decay and implied volatility in case Bitcoin stagnates before the Fed decision.

$420 Million in Longs at Risk if Fed Surprises Hawkish

A hawkish outcome from the Fed — or a surprise resurgence in inflation data — would instantly invalidate the bullish options positioning. The Consumer Price Index and Producer Price Index readings have recently eased, supporting the case for a hold, but any shift in the Fed's forward guidance could trigger a sharp repositioning across crypto derivatives.

Bitcoin's next support sits near $60,000, a level that has held during previous drawdowns this year, while resistance at $70,000 represents a psychological barrier that has capped rallies since March. The options market is now pricing the highest probability of a breakout around the Fed meeting window.
