Ethereum Exchange Supply Reaches Nine-Year Low, Indicating Positive Long-Term Outlook

Ethereum, the second-largest cryptocurrency in the world, is experiencing a significant event within the market landscape. It has been observed that the supply of Ethereum on centralized exchanges has plummeted to a low not seen in nine years. This particular metric, which has been widely discussed from September 25-28, 2025, showcases a notable shift in investor behavior towards long-term holdings, staking, and participation in decentralized finance (DeFi), moving away from short-term trading practices. While this scarcity typically indicates positive prospects for the future, the reactions within the market have been varied, with institutional accumulation and short-term price consolidation leading to questions about immediate volatility despite strong foundational elements underlying the cryptocurrency.

The sharp decline in the availability of Ethereum on exchanges implies that the asset class is maturing, with investors feeling more comfortable with self-custody and utilizing Ethereum’s capabilities for yield rather than keeping assets easily accessible for quick sales. This shift holds significant implications for both the future price trajectory of Ethereum and the wider cryptocurrency ecosystem, potentially setting the stage for a supply shock if demand continues to surpass the diminishing available supply.

The term “Ethereum’s exchange supply hitting a nine-year low” pertains to the total quantity of ETH held in wallets managed by centralized cryptocurrency exchanges dropping to levels last seen in July 2016. This movement of Ethereum away from trading platforms has been a consistent trend since mid-2020, with a sudden acceleration occurring in mid-July 2025. By late September 2025, the balances on centralized exchanges had plummeted to about 14.8 million ETH, a staggering drop of 52% from peak levels of around 31 million ETH. Tracking entities like Glassnode and CryptoQuant have been pivotal in monitoring this development, with CryptoQuant reporting the Ethereum Exchange Supply Ratio (ESR) reaching 0.14, its lowest point since July 2016. The sheer magnitude of withdrawals is striking, with over 2.7 million ETH, valued at about $11.3 billion, leaving exchanges in the month leading up to late September 2025. This movement away from exchanges is mainly driven by institutional investors and high-net-worth individuals amassing ETH, transferring it to cold storage, staking platforms, or employing it in DeFi applications.

Key drivers behind this trend include institutional investors, especially those linked to newly launched U.S. spot ETH Exchange-Traded Funds (ETFs) and corporate treasuries. Since April 2025, about 68 entities have collectively acquired 5.26 million ETH, valued at roughly $21.7 billion. These institutional players, like BitMine (NYSE: BMNR) chaired by Tom Lee, now control almost 10% of the total ETH supply, with the majority of these assets being staked instead of being retained on exchanges. Despite this fundamentally bullish indicator, ETH prices saw a slight decline of around 10-11% in the week preceding late September 2025, dropping below $4,100, showcasing potential short-term profit-taking activities or broader market influences.
