Deribit's July 26 Bitcoin options board is stacked. More than 20,000 call contracts are open at both the $70,000 and $72,000 strikes — roughly 27,000 at $70,000 and 21,000 at $72,000 — making them the two largest call concentrations for that expiry. A single block trade added to the pile: someone bought 20,000 July 26 calls at $70,000 and sold the same number at $72,000, creating a bull call spread with an aggregate gross notional of about $2.5 billion at prevailing Bitcoin prices.
The $70k–$72k call wall
Open interest that size doesn't reveal who's on the other side or what their broader portfolio looks like. But the concentration is real. Across all expiries, CryptoSlate's July 17 review found roughly $4.5 billion in call open interest between $70,000 and $80,000. The July 26 expiry alone accounts for a big chunk of that.
Bitcoin was trading near $64,289 as of July 20, 08:24 UTC — about 9% below the $70,000 strike. The options expire July 26, two days after the Federal Reserve's next policy decision (FOMC meeting July 28–29, decision July 29). That timing isn't an accident.
The bull spread trade
The block trade — buying 20,000 July 26 $70,000 calls and selling the same number of $72,000 calls — is a textbook bull call spread. It reaches maximum payoff if Bitcoin finishes at or above $72,000 at expiry. It can express a directional view, offset other positions, or hedge. The counterparty's intent isn't public, but the size is hard to ignore.
A bull spread caps both upside and downside. The buyer's maximum loss is the net premium paid; the maximum gain is the spread width ($2,000) minus that premium. At current spot, the trade is betting on a roughly 12% rally in six days.
FOMC and macro backdrop
Bitcoin pushed toward $65,000 on US inflation relief earlier this month, but escalating US-Iran hostilities could revive inflation and rate concerns, CryptoSlate reported July 14. The Fed's July 29 decision lands just before the options expire — any hawkish surprise could cap the rally.
Prediction markets aren't pricing a $70,000 touch as a sure thing. A July 20 snapshot gave Bitcoin a 14.5% probability of hitting $70,000 in July, 4.1% for $72,500, and 34.5% for $67,500. The most likely outcome, at 67.4%, was $62,500 — below current spot.
On-chain context
CryptoSlate's July 19 on-chain analysis identified a recent-buyer cost-basis test near $69,000 and a conditional lower stress boundary at $52,891. That $69,000 level sits just below the $70,000 call wall, suggesting a zone where sellers could emerge if the rally gets that far.
US spot Bitcoin ETF inflows have been positive but modest: $197 million from July 6–10 and $75 million from July 13–17, per Farside data. Not the kind of flood that would alone push price through $70,000.
The July 26 expiry is the next concrete event. Whether the $70,000–$72,000 call wall acts as a magnet or a ceiling depends on what the Fed says — and what happens in the Middle East — in the next nine days.
