The options/futures OI ratio represents the proportionality of unfastened involvement successful options contracts comparative to futures contracts. A higher ratio indicates a greater accent connected options trading than futures trading.
Bitcoin’s options/futures unfastened involvement (OI) ratio has consistently outpaced Ethereum’s, raising questions astir the underlying drivers. Data from CoinGlass shows that Bitcoin’s ratio has been climbing from 57.80% to 69.60% since the opening of March, portion Ethereum’s ratio has risen much modestly from 26.9% to 32.98%.
This gap, with Bitcoin’s ratio astir treble Ethereum’s each day, suggests a stronger penchant for options implicit futures among Bitcoin traders. To recognize why, we tin analyse the options OI and terms show for some assets implicit this play alongside broader marketplace trends.

First, the standard of options enactment provides context. Bitcoin’s options OI grows from $28.09 cardinal connected March 2 to $34.82 cardinal connected March 6, a 24% increase.

Ethereum’s options OI, portion besides rising 27% from $5.10 cardinal to $6.47 billion, remains 5–6 times smaller successful implicit terms. This disparity reflects Bitcoin’s larger marketplace cap, which historically runs 3–5 times higher than Ethereum’s, attracting much trading measurement and liquidity. Greater liquidity draws some organization and retail traders to Bitcoin options, often utilized for hedging oregon leveraging terms movements successful a much established market. Spot Bitcoin ETF’s Authorized Participants usage some futures and options to make gross portion minimizing hazard successful facilitating baskets of Bitcoin to fulfill ETF inventories.

Price show successful March further highlights the divergence. Bitcoin’s terms increases from $84,413 connected March 1 to $90,624 connected March 6, a 7.4% gain, contempt volatility with a highest astatine $94,238 connected March 3 and a dip to $86,212 connected March 4. Starting astatine $2,216, Ethereum’s terms rises to $2,297 by March 6, a 3.7% gain, but experiences a sharper driblet from $2,519 connected March 2 to $2,145 connected March 3. Bitcoin’s stronger nett summation and higher volatility align with its rising options/futures OI ratio, arsenic traders apt usage options to capitalize connected oregon hedge against these swings.
Ethereum’s much humble terms question and little implicit terms whitethorn trim the perceived request for options-based strategies, keeping its ratio little contempt dependable options OI growth.
Market size and liquidity play a important relation successful Bitcoin’s higher ratio. With a larger market, Bitcoin people sees much implicit trading activity, supporting a robust options market. Higher liquidity makes Bitcoin a preferred prime for traders looking to negociate risk, chiefly done options offering flexibility implicit futures. With a smaller market, Ethereum sees a greater reliance connected futures for directional speculation, reflecting its little developed derivatives ecosystem.
Hedging request besides contributes to the gap. With swings similar the 11.7% emergence and 8.5% drop, Bitcoin’s terms volatility prompts traders to favour options for hazard management, particularly fixed Bitcoin’s ascendant relation successful the crypto space. This is evident successful the options OI maturation tracking terms betterment aft March 4. Ethereum’s volatility, including a 14.9% drop, is notable but little impactful successful implicit presumption owed to its little price, resulting successful a little options/futures OI ratio arsenic traders thin toward futures.
Institutional information further widens the divide. Bitcoin has seen greater organization adoption, peculiarly since the support of spot Bitcoin ETFs successful 2024, bolstering its derivatives market. Institutions often similar options for superior ratio and flexibility, boosting Bitcoin’s options/futures OI ratio. Ethereum, portion benefiting from spot ETH ETFs trading since mid-2024, lags behind.
The weaker show of Ethereum ETFs, with year-to-date returns ranging from -1.78% to -36.48%, signals little capitalist assurance compared to Bitcoin ETFs, which, contempt antagonistic YTD returns, negociate larger plus bases and higher trading volumes—like the iShares Bitcoin Trust, which has $57.8 cardinal successful assets versus the iShares Ethereum Trust’s $376.60 million.
This underperformance successful Ethereum ETFs apt discourages organization adoption, arsenic institutions prioritize assets with stronger marketplace validation and liquidity. Reduced organization involvement successful Ethereum ETFs limits the maturation of its options market, arsenic institutions are cardinal drivers of options enactment for hedging and speculation. Consequently, Ethereum’s options/futures OI ratio remains lower, reflecting a little mature derivatives marketplace compared to Bitcoin’s.
Finally, marketplace maturity gives Bitcoin an advantage. Bitcoin has a longer past and a much developed options market. Traders presumption Bitcoin options arsenic a reliable instrumentality for speculation oregon hazard management, portion Ethereum’s options market, inactive maturing, sees little enactment comparative to futures.
The information from March 2025 supports this, with Bitcoin’s stronger terms performance, larger options market, and greater organization backing driving its higher options/futures OI ratio. Despite maturation successful options OI, Ethereum remains constrained by its smaller marketplace and weaker organization adoption, keeping its ratio little and highlighting Bitcoin’s dominance successful the crypto derivatives market.
