Large traders bought $2.5 billion in notional bitcoin call spreads on Deribit this week, structuring positions that pay off if BTC rises above $70,000 by July 31 but cap gains at $72,000. According to Deribit's chief commercial officer Jean-David Péquignot, the flow came in 20,000-contract blocks pairing long $70,000 calls with short $72,000 calls at the same expiry, a textbook bull call spread.
Why it matters
Flow of this size and strike precision rarely comes from retail. The capital requirement, plus the exact targeting of a $2,000-wide payoff window, points squarely at institutional positioning that expects a defined catalyst rather than a generic rally bet. The expiry of July 31 sits just two days after the Federal Reserve's July 29 interest rate decision, and traders are explicitly aligning the trade with that event.
Fed funds futures currently imply a 75% to 80% probability the Fed holds rates at 3.5% to 3.75%, with the remaining odds split between a hike and, to a lesser extent, a cut. June inflation data gave markets initial relief: headline CPI decelerated sharply, helped by an oil pullback tied to a US-Iran ceasefire. Core inflation, which strips out food and energy, printed flat.
Market impact
That relief narrative is now being tested. Tensions between the US and Iran escalated this week, fresh strikes disrupted flows through the Strait of Hormuz, and both WTI and Brent posted their largest gains since March. Some analysts argue the June data is backward-looking and urge caution heading into the meeting.
Bitcoin itself has bounced from under $58,000 earlier this month to roughly $64,000, and the spread flow suggests at least some large traders are looking past the geopolitical noise. The structure caps the upside, so the real signal is not a moonshot bet but a conviction that the Fed decision hands BTC the catalyst it needs to push toward $72,000.
Frequently asked questions

-
What is a bull call spread and why use it for BTC?

-
What are markets pricing for the July Fed decision?
Fed funds futures imply a 75% to 80% probability the Fed holds at 3.5% to 3.75%, with the remaining odds split between a hike and, to a lesser extent, a cut.
-
How does the US-Iran flare-up complicate the trade?
Fresh strikes this week disrupted Strait of Hormuz flows, lifting WTI and Brent by the most since March. Some analysts argue June's tame inflation data is backward-looking and urge caution into the meeting.
