Ethereum is entering one of its tightest supply eras ever, with new data showing that exchange balances have dropped to their lowest point since 2016, just as corporate and institutional entities increase their ETH holdings at the fastest pace in years.

Ethereum’s exchange supply ratio has fallen to 0.137, according to CryptoQuant — a level last seen in the network’s earliest days.

In previous cycles, similar supply squeezes have preceded major price expansions, as less ETH available on exchanges reduces immediate sell-side pressure and signals growing conviction among long-term holders.

Supply leaves exchanges as institutions accumulate Ethereum

New data reveals a clear counter-trend: while ETH on exchanges continues to contract, entities holding ETH in treasury are steadily rising.

Figures from Coingecko show:

• 27 public companies and government-linked entities now hold ETH
• Combined holdings total 5,961,187 ETH
• Treasury ETH is valued at $17.7bn, up nearly 50% from the previous reporting period
• Treasury ownership accounts for 4.94% of all ETH

The list includes U.S.-listed firms such as Tom Lee’s BitMine Immersion, SharpLink, Coinbase Global, and others. 

Notably, BitMine Immersion added 407,331 ETH in the last 30 days alone — one of the most aggressive accumulation streaks by a public entity in ETH’s history.

This expansion of corporate ETH reserves adds a layer of structural demand that did not meaningfully exist in previous cycles.

Why Ethereum’s supply is tightening

Multiple forces are contributing to the decline in exchange balances:

• Staking: Nearly 37 million ETH remains locked in validators
• L2 ecosystems: Base, Arbitrum, Optimism, and others continue absorbing ETH liquidity
• Treasury adoption: Corporates increasingly view ETH as an operational and strategic asset
• Long-term holding behavior: Investors are withdrawing to self-custody rather than actively trading

With sell-side supply dwindling and institutional absorption rising, Ethereum appears to be entering a low-liquid, high-demand environment — one that historically precedes strong upward volatility.

What this could mean for ETH’s price

Ethereum recently traded around $2,900, stabilizing after a choppy few weeks. While short-term price action remains tied to broader market sentiment, the supply structure is shifting beneath the surface.

If exchange balances continue to fall and treasury accumulation remains steady, Ethereum could face a classic “supply shock” scenario — where even moderate demand triggers outsized upside.

Final Thoughts

• Ethereum is experiencing its tightest exchange-supply conditions since 2016, setting the stage for a potential supply squeeze.
• Institutional accumulation of nearly 6 million ETH adds strong long-term support and introduces a new demand engine not present in earlier cycles.
