Understanding the Options/Futures Open Interest Ratio
The options/futures OI ratio is a key metric that reflects the proportion of open interest in options contracts relative to futures contracts. A higher ratio indicates a greater emphasis on options trading compared to futures trading.
Bitcoin vs. Ethereum: Analyzing the Discrepancy
Bitcoin’s options/futures open interest (OI) ratio has consistently surpassed that of Ethereum, sparking curiosity about the underlying factors driving this trend. Data from CoinGlass reveals a notable increase in Bitcoin’s ratio from 57.80% to 69.60% since the start of March, while Ethereum’s ratio has seen a more modest rise from 26.9% to 32.98%.
Examining the Reasons Behind the Disparity
The significant gap between Bitcoin’s and Ethereum’s ratios, with Bitcoin’s ratio consistently double that of Ethereum’s, indicates a stronger inclination towards options trading among Bitcoin traders. To delve deeper into this phenomenon, it is crucial to analyze the options OI, price performance, and broader market trends for both cryptocurrencies during this period.
Key Findings and Observations
- Bitcoin’s options OI has witnessed a substantial 24% increase, reaching $34.82 billion from $28.09 billion in just a few days.
- Ethereum’s options OI has also grown by 27%, climbing from $5.10 billion to $6.47 billion within the same timeframe.
- Bitcoin’s larger market cap and higher liquidity compared to Ethereum attract more trading volume and liquidity, leading to a preference for Bitcoin options among traders.

Impact of Price Movements and Market Size
Price performance in March underscores the divergence between Bitcoin and Ethereum, with Bitcoin experiencing a stronger net gain and higher volatility. This aligns with the rising options/futures OI ratio for Bitcoin, as traders leverage options to capitalize on or hedge against price fluctuations. Ethereum’s more subdued price movement and lower absolute price contribute to a lower options/futures OI ratio, despite steady growth in options OI.
Factors Influencing the Options/Futures OI Ratio
- Market size and liquidity play a pivotal role in Bitcoin’s higher ratio, with greater trading activity and liquidity supporting a robust options market.
- Hedging demand, price volatility, and institutional participation also contribute to the disparity between Bitcoin’s and Ethereum’s options/futures OI ratios.
- Bitcoin’s longer history and more developed options market give it a competitive edge over Ethereum in the crypto derivatives landscape.
Overall, the data from March 2025 underscores Bitcoin’s dominance in the crypto derivatives market, driven by its stronger price performance, larger options market, and higher institutional backing, which collectively contribute to its higher options/futures OI ratio compared to Ethereum.
