Stablecoin Reserves Drop to $64B as Binance Share Hits 68.5%
Stablecoin exchange reserves fell 20% to $64B, with Binance capturing 68.5%. Total supply hits $310B but most is off-exchange, making netflows the key signal for spot buying.
Stablecoin reserves across centralized exchanges have fallen to $64 billion from roughly $80 billion, cutting immediately available spot-buying liquidity by about 20% from late-2025 levels. Binance increased its share of that shrinking pool to 68.5%, up from nearly 60%. The concentration gives the exchange outsized control over which stablecoin liquidity remains deployable to the market, while rival venues hold a smaller and shrinking fraction.
The decline in exchange reserves sits against a record high in total stablecoin supply. Across all venues and wallets, the market holds roughly $310 billion in stablecoins, according to DeFiLlama, far above the $64 billion on exchanges. USDT alone accounts for about $183 billion, and USDC represents another $73 billion to $74 billion. Together, the two tokens make up roughly 83% of the market.
Most of that supply now supports self-custody, DeFi protocols, payments, and other on-chain activity rather than exchange order books. The gap between total supply and exchange reserves separates broader liquidity from funds positioned for immediate market deployment. Exchange netflows become the stronger signal. Rising stablecoin deposits would push capital closer to spot purchases; continued outflows would keep that liquidity outside centralized markets.
Within Binance's own reserves, capital has been changing form without materially increasing available buying power. The exchange's average monthly reserve value ran at roughly $42.92 billion, rising only 0.44% per month. Daily USDC inflows reached $125.4 million. The gains largely reflected a shift in reserve composition rather than new capital entering the exchange. About $929 million of USDT entered through TRON (TRX) while $765 million left through Ethereum (ETH), showing capital migrating between chains.
USDC's share of Binance's reserves recovered to 0.0986. It remained below its six-month average of 0.1128. The lack of growth in overall reserve size limits the exchange's ability to expand spot-buying capacity. For conditions to shift, reserves would need to grow to $48.17 billion while the USDC ratio rises above its longer-term average.
