The choices/futures OI ratio represents the proportion of open curiosity in choices contracts relative to futures contracts. A better ratio signifies a better emphasis on choices buying and selling than futures buying and selling.
Bitcoin’s choices/futures open curiosity (OI) ratio has persistently outpaced Ethereum’s, elevating questions in regards to the underlying drivers. Information from CoinGlass exhibits that Bitcoin’s ratio has been climbing from 57.80% to 69.60% for the reason that starting of March, whereas Ethereum’s ratio has risen extra modestly from 26.9% to 32.98%.
This hole, with Bitcoin’s ratio roughly double Ethereum’s every day, suggests a stronger choice for choices over futures amongst Bitcoin merchants. To know why, we are able to study the choices OI and worth efficiency for each belongings over this era alongside broader market tendencies.
First, the dimensions of choices exercise offers context. Bitcoin’s choices OI grows from $28.09 billion on March 2 to $34.82 billion on March 6, a 24% enhance.

Ethereum’s choices OI, whereas additionally rising 27% from $5.10 billion to $6.47 billion, stays 5–6 occasions smaller in absolute phrases. This disparity displays Bitcoin’s bigger market cap, which traditionally runs 3–5 occasions greater than Ethereum’s, attracting extra buying and selling quantity and liquidity. Larger liquidity attracts each institutional and retail merchants to Bitcoin choices, usually used for hedging or leveraging worth actions in a extra established market. Spot Bitcoin ETF’s Approved Contributors use each futures and choices to generate income whereas minimizing threat in facilitating baskets of Bitcoin to meet ETF inventories.

Worth efficiency in March additional highlights the divergence. Bitcoin’s worth will increase from $84,413 on March 1 to $90,624 on March 6, a 7.4% acquire, regardless of volatility with a peak at $94,238 on March 3 and a dip to $86,212 on March 4. Beginning at $2,216, Ethereum’s worth rises to $2,297 by March 6, a 3.7% acquire, however experiences a sharper drop from $2,519 on March 2 to $2,145 on March 3. Bitcoin’s stronger web acquire and better volatility align with its rising choices/futures OI ratio, as merchants seemingly use choices to capitalize on or hedge towards these swings.
Ethereum’s extra modest worth motion and decrease absolute worth could scale back the perceived want for options-based methods, holding its ratio decrease regardless of regular choices OI progress.
Market measurement and liquidity play a big position in Bitcoin’s greater ratio. With a bigger market, Bitcoin naturally sees extra absolute buying and selling exercise, supporting a sturdy choices market. Greater liquidity makes Bitcoin a most well-liked alternative for merchants trying to handle threat, primarily via choices providing flexibility over futures. With a smaller market, Ethereum sees a better reliance on futures for directional hypothesis, reflecting its much less developed derivatives ecosystem.
Hedging demand additionally contributes to the hole. With swings just like the 11.7% rise and eight.5% drop, Bitcoin’s worth volatility prompts merchants to favor choices for threat administration, particularly given Bitcoin’s dominant position within the crypto house. That is evident within the choices OI progress monitoring worth restoration after March 4. Ethereum’s volatility, together with a 14.9% drop, is notable however much less impactful in absolute phrases attributable to its cheaper price, leading to a decrease choices/futures OI ratio as merchants lean towards futures.
Institutional participation additional widens the divide. Bitcoin has seen better institutional adoption, notably for the reason that approval of spot Bitcoin ETFs in 2024, bolstering its derivatives market. Establishments usually desire choices for capital effectivity and adaptability, boosting Bitcoin’s choices/futures OI ratio. Ethereum, whereas benefiting from spot ETH ETFs buying and selling since mid-2024, lags behind.
The weaker efficiency of Ethereum ETFs, with year-to-date returns starting from -1.78% to -36.48%, alerts decrease investor confidence in comparison with Bitcoin ETFs, which, regardless of damaging YTD returns, handle bigger asset bases and better buying and selling volumes—just like the iShares Bitcoin Belief, which has $57.8 billion in belongings versus the iShares Ethereum Belief’s $376.60 million.
This underperformance in Ethereum ETFs seemingly discourages institutional adoption, as establishments prioritize belongings with stronger market validation and liquidity. Decreased institutional curiosity in Ethereum ETFs limits the expansion of its choices market, as establishments are key drivers of choices exercise for hedging and hypothesis. Consequently, Ethereum’s choices/futures OI ratio stays decrease, reflecting a much less mature derivatives market in comparison with Bitcoin’s.
Lastly, market maturity provides Bitcoin a bonus. Bitcoin has an extended historical past and a extra developed choices market. Merchants view Bitcoin choices as a dependable software for hypothesis or threat administration, whereas Ethereum’s choices market, nonetheless maturing, sees much less exercise relative to futures.
The info from March 2025 helps this, with Bitcoin’s stronger worth efficiency, bigger choices market, and better institutional backing driving its greater choices/futures OI ratio.
