The week of May 17 to May 24, 2025, marked a pivotal moment in the crypto markets as anticipation and eventual approval of the first spot Ethereum exchange-traded funds (ETFs) triggered dramatic price movements, record liquidations, and shifting market sentiment. This report analyzes key developments, price action, derivatives data, and investor behavior during this volatile period—highlighting how major regulatory milestones can both fuel rallies and expose market fragility.
Ethereum ETF Approval: From Hype to Reality
On May 20, 2025, news broke that the U.S. Securities and Exchange Commission (SEC) had formally requested exchanges accelerate their filings for spot Ethereum ETFs under Form 19b-4. This unexpected regulatory push was interpreted as a strong signal of imminent approval. Bloomberg Intelligence analysts responded by raising the odds of final approval to 75%, a significant shift in market expectations.

The reaction was immediate: Ethereum (ETH) surged 18% within hours, climbing from around $3,350 to a peak of **$3,950. The rally was fueled by aggressive long positioning across derivatives markets. However, momentum came at a cost—over $75 million in short positions were liquidated** on May 20 alone, according to CoinGlass data, reflecting intense bearish pressure being squeezed out.
Yet, when the official approval was confirmed on May 23, the market delivered a classic "buy the rumor, sell the news" reaction. ETH rapidly dropped from $3,950 to a low of **$3,524, triggering massive long liquidations totaling $88.16 million**. Despite the sell-off, confidence quickly returned as buyers stepped in, pushing ETH back above **$3,800** by the end of the week.
This sequence underscores a critical dynamic in crypto markets: regulatory catalysts drive extreme volatility, with sentiment swinging from euphoria to fear—and back again—within days.
Bitcoin’s Role Amid Ethereum’s Spotlight
While Ethereum dominated headlines, Bitcoin (BTC) also saw notable movement. BTC followed ETH’s upward trajectory on May 20, rising in tandem amid broad market optimism. However, unlike ETH, Bitcoin did not experience a sharp post-approval correction. Instead, BTC demonstrated relative stability, reinforcing its role as a market stabilizer during altcoin-driven volatility.
Key observations from BTC’s derivatives and on-chain metrics:
- Trading volume spiked on May 20, aligning with the surge in ETH-related sentiment.
- Open interest remained stable, indicating no major shift in leveraged positioning.
- Implied volatility declined, suggesting growing confidence in BTC’s price floor.
- Funding rates turned positive, signaling renewed bullish sentiment across perpetual futures markets.
These patterns suggest that while Ethereum’s ETF news was the primary catalyst, Bitcoin absorbed much of the risk-on sentiment without amplifying leverage—a sign of maturing market structure.
Derivatives Data: Volatility Peaks and Sentiment Shifts
Derivatives markets provided crucial insights into trader psychology throughout the week.
Implied Volatility Divergence
A striking divergence emerged between Bitcoin and Ethereum:
- ETH implied volatility rose sharply, reflecting uncertainty around the ETF decision and anticipation of large price moves.
- BTC implied volatility decreased, indicating traders viewed Bitcoin as a safer haven amid speculative froth.
This divergence highlights how institutional-grade derivatives markets are beginning to differentiate between asset-specific risks and broader market trends.
Funding Rates and Market Breadth
Funding rates across major exchanges turned positive after May 20, showing that traders were willing to pay premiums to maintain long positions. More importantly, market breadth indicators—which measure the proportion of assets participating in a rally—showed improving conditions. Though concentrated in ETH initially, gains gradually spread across large-cap altcoins by May 23, signaling broadening market participation.

On-Chain and Exchange Metrics
Exchange flows and wallet activity offered additional context:
- Net inflows to centralized exchanges spiked briefly on May 23, coinciding with profit-taking after ETH’s peak.
- Large wallets (>10,000 ETH) showed minimal movement, suggesting long-term holders remained unfazed by short-term volatility.
- Stablecoin supply ratios held steady, indicating no systemic de-risking or capital flight.
These behaviors reflect a more resilient investor base—one less prone to panic selling after major news events.
Upcoming Catalyst: Federal Reserve Meeting (June 13, 2025)
With the Ethereum ETF chapter closing, attention now turns to macroeconomic drivers. The next Federal Reserve interest rate decision is scheduled for June 13, 2025, approximately 20 days away. Current market pricing suggests high odds of a hold, but any shift in inflation or employment data could reignite volatility across both traditional and digital asset markets.
Historically, periods of low-rate expectations have been favorable for risk assets like cryptocurrencies. If the Fed signals continued patience, it could provide a supportive backdrop for sustained crypto rallies—especially if institutional adoption accelerates post-ETF launch.
