Ethereum's exchange supply has dropped to roughly 15.5 million coins, the lowest level in years, as holders move ETH into self-custody and staking. MVRV momentum turned positive in late August, showing the average holder is back in profit.

Ethereum exchange supply hits 15.5M ETH, lowest in years
Ethereum held on centralized exchanges fell to about 15.5 million coins, the smallest balance in years, as the share of the asset's supply available for immediate sale kept shrinking through the third quarter.
The drawdown marks a multi-year low for exchange-held ETH and extends a trend that has run since the start of 2026, according to data compiled by BeInCrypto. The same dataset showed MVRV momentum turning positive in late August, a shift that indicates the average holder moved back into profit.
"Exchange balances are the cleanest read we have on how much ETH is actually for sale at any moment," Jason Wu, an on-chain analyst who tracks Ethereum flows, said. "When that number keeps grinding lower, the market is telling you the marginal holder is not a seller."
The mechanics matter more than the headline. Coins that leave a centralized venue move into self-custody, staking contracts, or institutional custody accounts, and none of those destinations can be sold with a single order. That removes resting ask liquidity from order books. The effect is asymmetric: the same dollar of buying pressure moves price further when the visible float is smaller, and the same is true in reverse when demand fades.
MVRV, or market value to realized value, compares ETH's market capitalization with the aggregate cost basis of every coin that has moved on-chain. A positive momentum reading means the ratio is rising, which historically coincides with holders sitting on gains rather than losses. Late August's turn higher came after a stretch in which the metric had been drifting, and it lines up with the exchange-supply decline rather than contradicting it.
The two signals describe the same behavior from different angles. Falling exchange reserves show where coins are not; improving MVRV shows why holders are reluctant to move them back. Together they sketch a market where the supply side has thinned while the average position sits in profit — a combination that has preceded sharp upside moves in past cycles, though the same thinness cuts both ways if demand stalls.
Ethereum's position within the broader market adds context. ETH dominance stood at 10.9% of total crypto market capitalization, against Bitcoin's 56.9%, according to CoinGecko data. The gap means ETH remains a rotation destination rather than the default holding, and flows into the asset depend heavily on whether capital is moving down the risk curve at all.
For traders, the practical question is what would reverse the trend. A sustained rise in exchange balances would signal holders preparing to sell, and that would be the first genuine threat to the supply-shock case. Until then, the number to watch is the same one that produced this story: whether 15.5 million ETH holds as a floor or keeps falling.
