ETH exchange supply hits lowest since 2016

TLDR

Ethereums exchange balances have dropped to their lowest level since 2016, showing that much more ETH is held off exchanges in staking and self-custody.

1. On-chain analytics put ETH on centralized exchanges at roughly 15 to 16 million, a near decade low, while total supply is about 121 million ETH.
2. The drop is driven by sustained staking growth, self-custody, and large institutional holders, which reduce immediately sellable supply but do not guarantee higher prices.
3. The key for traders is whether demand, from spot buyers, ETFs, and derivatives, strengthens into this tighter supply backdrop or stays weak and allows further downside.

Confidence: high because multiple independent analytics firms report similar lows.

Deep Dive

1. How Low Exchange Supply Has Gotten

Recent on-chain analysis cites ETH reserves on exchanges around 16.2 million coins, the lowest level since 2016, meaning far less ETH is parked on centralized venues ready to sell.

Other data points show exchange balances falling to about 15.85 million ETH, described as a nearly 10 year low, and trending even lower toward 14 million from prior peaks above 35 million ETH on exchanges.

At the same time, total ETH supply is around 121.55 million, so only a bit more than 10 percent of all ETH now sits on exchanges, with the rest spread across staking, treasuries, and private wallets.

2. Why ETH Has Moved Off Exchanges

One major driver is staking. Several analyses note roughly 37 to 38 million ETH locked in staking, including large corporate treasuries that have staked millions of ETH for yield rather than keeping it liquid on exchanges.

Institutional products and treasuries add to this effect. Spot Ether ETFs have seen sustained inflows in recent weeks, and firms like Bitmine and Sharplink collectively control several percent of supply, much of it staked rather than exchange based.

Since mid 2025, net flows from exchanges have mostly been negative, as investors move ETH into self-custody and staking. That structurally reduces immediate sell pressure, even during corrective phases.

3. Price Impact And What To Watch

Historically, falling exchange balances are considered bullish because they imply fewer coins are available to dump quickly, and any spike in demand can produce sharper upside moves.

However, early 2026 showed that exchange outflows alone are not enough. Despite persistent net outflows and shrinking exchange reserves, ETH still saw sharp drawdowns when macro shocks or weak demand hit.

Key things to monitor now are net exchange flows (do they flip back to sustained inflows), ETF and spot fund flows, staking share, and derivatives positioning such as funding and liquidations, which can amplify moves in either direction.

Conclusion

ETHs exchange supply hitting its lowest level since 2016 signals a long running shift toward staking, institutional treasuries, and self-custody. That leaves less ETH immediately available to sell, but recent history shows prices can still fall when macro conditions or demand are weak. The combination of tight supply and still-fragile demand sets up a regime where changes in ETF flows, spot buying, or derivatives positioning can have an outsized impact on ETHs next big move.
