At 16:00 on July 21, 2025, the ETH/BTC trading ratio was 0.0652, meaning that 1 Ethereum could be exchanged for 0.0652 bitcoins. This was a 4.3% decrease compared to the same period last month, but an 8.7% increase compared to the beginning of the year. This data is derived from real-time aggregation of leading exchanges such as Coinbase and Binance, with the price deviation rate controlled within 0.15%. The intraday fluctuation range reached ±1.8%, and the 30-day annualized volatility rose to 45%, significantly higher than the average of 38% last year. For instance, at 15:42 Beijing time, Binance Exchange witnessed a single market sell of 5,000 ETH, causing the ratio to instantly drop to 0.0648 with an amplitude of 0.6%. However, the liquidity buffer layer absorbed 90% of the selling pressure at 0.0650.
The derivatives market and arbitrage mechanisms intensify ratio fluctuations
The funding rate for ETH/BTC perpetual contracts reached -0.02% on July 20th, marking the first negative value in three months and indicating that the proportion of short positions has risen to 55%. Cross-exchange arbitrage data shows that when the price difference between Binance and OKX exceeds 0.0003, the quantitative robot can complete a triangular arbitrage within 500 milliseconds, with an annualized return of 18%. A typical case is that on July 15th, due to V God’s announcement of the postponement of the EIP-4844 upgrade, the ratio plunged by 3.5% in a single day, and arbitrage capital flowed in by 120 million US dollars in a single day, pushing the spread back to the median value of 0.00015. Galaxy Digital’s report indicates that the correlation between the ETH/BTC ratio and the Nasdaq Technology Stock Index has dropped from 0.6 to 0.3, weakening the effectiveness of traditional risk models.
On-chain activities and miners’ behaviors reshape the balance between supply and demand
Currently, the number of active addresses on Ethereum reaches 620,000 per day, while that on Bitcoin is only 450,000 per day. However, the daily selling pressure of Bitcoin miners (1,200 BTC) is 2.3 times that of Ethereum miners (approximately 520 BTC after converting 8,000 ETH). Youdaoplaceholder0 Significant behavioral differences: ETH Staking accounts for 22% of the circulating volume (with an annualized yield of 4.1%), while Bitcoin staking is almost zero. On-chain liquidation events show that when the ratio fluctuates by more than ±2.5%, the probability of the Aave protocol reaching the liquidation threshold in the “eth/btc” staking pool increases by 25%. The black swan event in 2025 – the 25% probability expectation of the US SEC classifying Ethereum as a security, if it comes true, could lead to a 12% drop in the ratio in a single day.
Technical indicators and cycle models predict a direction shift
The ETH/BTC ratio has remained at the lower band of the Bollinger bands (0.0648) for three consecutive weeks, and the RSI indicator has bottomed out at 33, forming a divergence. The regression model of the quantitative fund FalconX shows that the ratio is at a 1.2% discount to the 200-day moving average (0.0660), triggering a mean reversion strategy position-building signal. In historical samples, the 30-day winning rate of such signals has reached 72%. However, be vigilant against the risk of volatility squeeze: Data from the options market shows that the open interest of BTC put options with an exercise price of 0.060 has increased by 200% month-on-month, and market makers’ hedging operations may suppress the rebound of the ratio. Macro liquidity indicators suggest a turning point – if the Federal Reserve cuts interest rates by 50 basis points in September, statistical models predict that the ratio will rebound to the range of 0.0685±0.002.
