Bitcoin Options Expiry: $16B in Contracts Settle Friday at Deribit

Bitcoin faces one of the largest options expiries of the year on Friday. Roughly $15.9 billion in bitcoin options and $2.1 billion in ether options settle at 8:00 UTC on Deribit, the main venue for crypto options trading. Bitcoin was changing hands near $85.5k ahead of the cutoff, with the options book stacked in favor of higher prices.

The scale of this bitcoin options expiry is what sets it apart. The expiring bitcoin contracts alone represent about 37 percent of all outstanding bitcoin open interest on Deribit, which stood near $43.5 billion before settlement, according to chief executive Luuk Strijers. Open interest is the dollar value of active contracts, and each contract covers one BTC or one ETH.

A book built for higher prices

Positioning leans bullish. The put-call open-interest ratio sits at 0.69, which means call bets outweigh puts by a wide margin. Strijers told CoinDesk the ratio shows the book was built for higher prices.

Most of those calls are winning. About 55 percent of the $9.4 billion in call notional is in the money, while the puts are almost entirely underwater. Combined, roughly a third of the entire $15.9 billion book currently holds intrinsic value. An option is in the money when the market price sits on the favorable side of its strike: above it for calls, below it for puts.

The $70k strike carries more open contracts than any other level, and the calls there are deep in the money. Open interest also piles up at the $85k, $90k, $95k and $100k call strikes, where large call condor blocks are coming into play with spot near $85.5k. On the put side, defensive structures anchor at $60k, $70k and $75k, creating layered support that Deribit's chief commercial officer, Jean-David Péquignot, reads as a price floor around $75k.

One number getting attention is max pain, the price at which option buyers would collectively lose the most at expiry. For bitcoin it sits at $75k, well below the current spot price. Deribit describes that level as a "soft magnet" for price heading into settlement, though the theory that option sellers steer price toward it is widely debated.

How bitcoin options actually work

An option is a contract that gives its buyer the right, but not the obligation, to buy or sell an asset at a fixed price before a set date. A call profits when the price rises past the strike; a put profits when it falls below it. Traders pay an upfront premium for that right, and if the market never reaches the strike, the premium is the most they can lose.

That structure is why expiries move markets. Dealers who sold calls must buy the underlying asset as its price climbs, to stay hedged against the contracts they wrote. Their buying adds demand on the way up, and the effect reverses when the contracts settle and the hedges come off.

Why the rally may have been options-driven

Bitcoin's climb through the $80k-$87k range may owe something to the expiry itself. As prices rose, dealers short on calls had to keep buying spot bitcoin to stay hedged, and that mechanical buying added fuel to the rally, according to Strijers.

Once settlement clears, that support disappears. Strijers expects the pinning effect to fade after the expiry, which can open the door to more short-term volatility and a reset of bitcoin's recent trading range. Traders will also watch how positions roll into the October and December expiries. Rollover means closing current contracts while opening similar ones at later dates, and the size of the roll will shape positioning for the rest of the quarter.

What to watch after settlement

The immediate focus is price action around $85k. If bitcoin holds above it through the settlement window, the in-the-money calls pay out for buyers and dealers unwind their hedges in an orderly way. A sharp move in either direction during that window can still shake out leveraged positions, since quarterly settlements have grown into market-moving events of their own.

That is a change from a few years ago. The crypto options market has expanded many times over since 2020, as traders combine options with spot and futures to express views on direction, volatility and time decay. Deribit's quarterly expiries fall on the last Friday of March, June, September and December, according to market coverage of the exchange's schedule, and each one clears out a chunk of open interest big enough to reset the board.

For this quarter, the board is unusually large. Friday's bitcoin options expiry clears about a third of Deribit's bitcoin open interest in a single morning, with bitcoin trading well above the level where option buyers would hurt most. Whatever happens next, the market that wakes up after 8:00 UTC will look different from the one that went into it.
