ETH/BTC Ratio Sinks to 10-Month Low — What Will Turn Ethereum’s Tide Against Bitcoin?

Ether hit a fresh milestone of the wrong kind on Tuesday, May 12: its exchange rate against Bitcoin fell to 0.02835, the weakest reading in ten months and the lowest the ETH/BTC pair has traded since July 2025. The ratio is now more than 35% below its August 2025 peak of 0.04324 and sits well beneath the long-term 200-week moving average of 0.04828. For a cryptocurrency that once regularly outpaced its larger rival during bull cycles, the sustained underperformance is prompting a hard reassessment across trading desks.

Tuesday's Sell-Off in Numbers

On May 12, Ether slid more than 2% in a single session while Bitcoin lost just over 1% — a divergence that, repeated over weeks, compounds into a substantial relative loss. As of mid-May, Bitcoin was trading in the $79,000–$82,000 corridor, buoyed by consistent ETF inflows, while Ether struggled to hold ground even during Bitcoin's calmer trading windows. The gap suggests that capital rotation into Bitcoin is structural, not merely a short-term tactical move by hedge funds.

ETF Flows Are the Key Differentiator

The root of Ethereum's relative weakness traces directly to the ETF ecosystem. U.S. spot Bitcoin ETFs have absorbed more than $3.29 billion in net inflows over the past two months, providing a near-continuous bid for BTC that has no parallel on the Ether side. While a staked Ether ETF from VanEck — which would use Lido Finance as its staking provider — is pending regulatory review with a mid-summer launch considered realistic, it has not yet materialized. Until fresh institutional demand for ETH arrives via an ETF vehicle, Bitcoin's pipeline advantage is likely to persist.

Ethereum Foundation Stakes Its Conviction

In a show of internal confidence, the Ethereum Foundation completed a staking commitment of 70,000 ETH — worth roughly $143 million at current prices — having deployed approximately $93 million of that total in a single day in early April. At the prevailing network staking yield of 2.7% to 3.8% annually, the position generates an estimated $3.9 million to $5.4 million per year for the Foundation. The move is symbolic as much as financial: it signals that Ethereum's core stewards are aligned with long-term holders rather than rotating out of the asset.

Clear Signing Standard Targets Security Gap

Beyond the price action, Ethereum's underlying network continued to develop. The Ethereum Foundation introduced a new “Clear Signing” standard designed to prevent users from unknowingly approving malicious transactions — a problem that has cost the ecosystem hundreds of millions of dollars through phishing campaigns in recent years. By requiring wallets and DeFi front-ends to display human-readable transaction details before signing, the standard aims to close one of the most exploited attack surfaces in decentralized finance.

The Bullish Counter-Argument

Not every indicator points bearish for Ethereum. The ETH/BTC ratio touched a similar depressed range in April 2026 before bouncing, suggesting that extreme undervaluation can attract contrarian buyers. Bitwise CIO Matt Hougan has argued that the forthcoming Fusaka upgrade — which is expected to dramatically increase Ethereum's blob capacity and reduce Layer 2 fees — could catalyze a reassessment of ETH's fee-capture potential. Additionally, approximately 31% of all Ether supply is now staked, reducing circulating float and supporting a long-term supply thesis.

What to Watch

The ETH/BTC ratio is the cleanest real-time barometer of relative sentiment. Traders and investors should watch for three potential catalysts that could shift its trajectory: formal approval of a staked Ether ETF, a definitive Fusaka upgrade timeline, and any sign of broad altcoin rotation after Bitcoin consolidates below $82,000. If none of those triggers materializes before summer, the 0.02835 floor may face further tests — and the question of whether Ethereum can reclaim its bull-cycle narrative will remain squarely on the table.
