Stablecoin liquidity on major centralized exchanges has deteriorated to a one-year low, raising doubts about the durability of recent cryptocurrency gains. According to CryptoQuant data cited by analyst Darkfost, ERC-20 stablecoin reserves on Binance fell to $41.6 billion in October, the lowest level in twelve months. The balance peaked near $51 billion in late November 2025 before losing roughly $9 billion. Since April, Binance's reserves have contracted by $6.3 billion, while the 90-day rate of change remains negative at -4.7%.
The drain extends beyond Binance, which holds more than 70% of stablecoin reserves across centralized exchanges. Coinbase Advanced recorded $2.5 billion in outflows since April, OKX lost $2.4 billion, and Bybit shed $2.3 billion. Combined, the four venues suffered about $13.5 billion in stablecoin outflows. Because data tracks only ERC-20 tokens, the actual figure could be higher. Aggregate issuance has not offset the move: Tether's USDT remained near $183 billion since April, while USD Coin declined from $78 billion to $72 billion.
Bitcoin still rallied more than 30% from its August bottom to $86,597 on September 22, but spot volume tells a different story. Average daily Bitcoin spot turnover fell from $38.6 billion in April to $28.2 billion in October, a decline of 27%. Bitcoin traded around $83,350 in late October, about 4% below the September high, while Ethereum pulled back roughly 11% from $2,775. Funding rates on Binance and Bybit remained near the neutral 0.01% level. Analysts suggest the price rise was fueled by leverage and rotation among existing holders rather than fresh stablecoin inflows, which may limit the market's ability to sustain breakouts.
A separate Coin Metrics study supports a more nuanced view of stablecoin flows. Over four years of weekly data, higher perpetual funding rates were associated with supply increases for both USDT and USDC, but after rallies USDT issuance tended to accelerate the following week while USDC minting slowed. Statistical models explained only 13% of weekly USDC supply variation and 16% for USDT, leaving most of the movement tied to unobserved factors. On October 19, the USDC supply rate on Aave v3 was 11.5% on Ethereum versus 3.1% for USDT, compared with a three-month Treasury yield of 4.27%.
Circle's USDC issuance is typically driven by institutional deposits for settlements, payments and collateralized lending, while Tether's USDT is often used for direct trades or to preserve dollar value after de-risking. These distinctions mean aggregate stablecoin supply is not a simple dry-powder indicator for Bitcoin demand. Market participants are now watching the October monthly close and whether Binance's 90-day stablecoin rate of change turns positive as a sign that capital inflows are returning to exchanges.
