The amount of Ether held on cryptocurrency exchanges has fallen to 14.5 million ETH, the lowest level since the network’s earliest days in 2015, according to on-chain data from Glassnode. The declining exchange balance, which has been trending downward for most of 2025, suggests a continued shift in holder behavior away from short-term trading toward long-term strategies.
The figure represents roughly 12% of Ethereum’s total circulating supply, down from over 20% in mid-2020. The drop accelerated in the second quarter of 2025 as more tokens moved into staking contracts, decentralized finance protocols, and self-custodial wallets.

What Is Driving the Supply Decline
Several factors are pulling ETH off exchanges. The most prominent is the ongoing shift to proof-of-stake. Since the Merge in September 2022, holders have been able to stake their ETH to earn yields, locking up tokens in the Beacon Chain deposit contract. As of July 2025, more than 34 million ETH — over 28% of the total supply — is staked, according to the Ethereum Foundation.
Simultaneously, the rise of liquid staking protocols like Lido and Rocket Pool has made it easier for smaller holders to participate without running a validator node. These protocols now hold a combined share of staked ETH that exceeds 40%, reducing the need for exchange-based liquidity.

Another factor is the broader trend toward self-custody. Following a series of exchange collapses and regulatory actions in prior years, many retail and institutional investors have moved funds to hardware wallets and non-custodial solutions. Data from Dune Analytics shows that the number of addresses holding at least 0.1 ETH has risen steadily, crossing 30 million in June 2025.
Implications for Price and Market Structure
A declining exchange supply is generally interpreted as a bullish signal because it reduces the amount of ETH readily available for sale. When fewer coins sit on exchange order books, even modest buying pressure can lead to sharper price movements.
However, analysts caution that the relationship is not linear. The supply decline also reflects the growing use of Ethereum as collateral in DeFi, which can introduce liquidity constraints during periods of market stress. In a sharp downturn, leveraged positions can be liquidated, forcing ETH back onto exchanges rapidly — a dynamic observed during the March 2020 crash and the 2022 bear market.
At current levels, the exchange supply is roughly half of what it was at the peak of the 2021 bull market, when ETH prices exceeded $4,800. The reduction in liquid supply is one reason some analysts project that the next cyclical rally could see price discovery above previous highs, though broader macroeconomic conditions remain a key variable.
How This Compares to Bitcoin
Bitcoin has experienced a similar trend. BTC exchange reserves have fallen to multi-year lows, with approximately 2.3 million BTC held on exchanges as of early July 2025, according to CoinGlass. The dynamics differ slightly: Bitcoin’s supply is capped at 21 million, while Ethereum’s supply has been net deflationary since the EIP-1559 upgrade, which burns a portion of transaction fees.
Since the implementation of EIP-1559 in August 2021, over 4 million ETH has been burned, reducing the total supply from its peak of 120.5 million. Combined with the exchange outflow, the net effect is a tightening of available supply across both centralized and decentralized markets.
What to Watch Next
The next major milestone for Ethereum is the Pectra upgrade, expected in late 2025, which will introduce improvements to validator efficiency and staking withdrawals. If the upgrade proceeds smoothly, it could encourage further staking inflows, deepening the supply squeeze.
Regulatory developments also remain a wild card. The U.S. Securities and Exchange Commission has not yet classified ETH as a security, but ongoing legal actions against other crypto projects have kept market participants cautious. Any clarity — or further uncertainty — could shift the trajectory of exchange balances.
For now, the 14.5 million ETH figure underscores a structural change in how Ethereum is held and used. Whether it translates into sustained price appreciation depends on demand from both retail and institutional buyers, which remains tied to broader adoption of decentralized applications and tokenization.
