Key takeaways:

Lined calls gained traction as cash-and-carry returns collapsed, however knowledge reveals they aren’t structurally suppressing Bitcoin’s worth.

Secure put-to-call ratios and rising put demand counsel hedging and yield methods coexist with bullish positioning.
As Bitcoin (BTC) worth entered a downtrend in November, merchants started forming theories about why institutional inflows and company accumulation did not maintain worth ranges above $110,000.
One clarification incessantly cited is the rising demand for Bitcoin choices, significantly these linked to the BlackRock iShares spot Bitcoin (IBIT) exchange-traded fund.

The mixture Bitcoin choices open curiosity climbed to $49 billion in December 2025 from $39 billion in December 2024, placing the lined name technique below nearer scrutiny.
Critics argue that by “renting out” their upside for a payment, massive buyers have unintentionally created a ceiling that stops Bitcoin from getting into its subsequent parabolic phase. To grasp this argument, it helps to view a lined name as a trade-off between worth appreciation and regular earnings.
In a lined name technique, an investor who already owns Bitcoin sells a name (purchase) choice to a different occasion. This offers the client the suitable to buy that Bitcoin at a hard and fast worth, comparable to $100,000 by a specified date. In return, the vendor receives an upfront money fee, just like incomes curiosity on a bond.
This choices technique differs from fastened earnings merchandise as a result of the vendor continues to carry a unstable asset, although their potential upside is capped. If Bitcoin rallies to $120,000, the vendor should promote at $100,000, successfully lacking the extra beneficial properties.
Merchants argue that this dynamic suppresses worth motion as a result of skilled sellers who buy these choices typically promote Bitcoin within the spot market to hedge their publicity, making a persistent “sell wall” round fashionable strike costs.
Options-based yield changed the collapsed money and carry commerce
This shift towards options-based yield is a direct response to the collapse of the cash and carry commerce, which entails promoting BTC futures whereas holding an equal place within the spot market.

For a lot of late 2024, merchants captured a gradual 10% to fifteen% premium. By February 2025, nevertheless, that premium had fallen beneath 10%, and by November it struggled to stay above 5%.
Searching for larger returns, funds rotated into lined calls, which supplied extra enticing annualized yields of 12% to 18%. This transition is obvious in IBIT choices, the place open curiosity jumped to $40 billion from $12 billion in late 2024. Even so, the put-to-call ratio has stayed secure beneath 60%.

If widespread “suppressive” name promoting have been really the dominant drive, this ratio would doubtless have collapsed because the market grew to become saturated with name sellers. As an alternative, the stability implies that for each yield-focused vendor, there’s nonetheless a purchaser positioning for a breakout.
The put-to-call ratio means that whereas some contributors are promoting upside name choices, a a lot bigger group is buying put (promote) devices as safety towards a possible worth decline.
The latest defensive stance is mirrored within the skew metric. Whereas IBIT put choices traded at a 2% low cost in late 2024, they now commerce at a 5% premium. On the similar time, implied volatility, the market’s measure of anticipated turbulence, declined to 45% or decrease from Could onward, down from 57% in late 2024.

Decrease volatility reduces the premiums earned by sellers, that means the motivation to deploy this so-called “suppressive” technique has truly weakened, whilst complete open curiosity has elevated.
Arguing that lined calls are holding costs down makes little sense when the sellers of these name choices stand to learn most if costs rise towards their goal ranges. Fairly than appearing as a constraint, the choices market has develop into the first venue the place Bitcoin’s volatility is being monetized for yield.
