Stablecoin reserves on centralized exchanges have fallen 20% from their 2025 peak to roughly $64 billion in 2026, while Binance’s share of the remaining liquidity has risen to 68.5%, according to CryptoQuant data.

The shift highlights a broader contraction in exchange liquidity, with Binance gaining relative share even as its own absolute reserves decline. That leaves less stablecoin capital on exchanges to absorb selling or support new purchases, potentially making markets more sensitive to large trades.
Why Is Stablecoin Liquidity Concentrating on Binance?
CryptoQuant’s report shows reserves at Coinbase, Bybit, OKX and smaller exchanges have declined more sharply, allowing Binance’s share to rise from the low-60% range in late 2025 to 68.5%.


CryptoQuant said the divergence shows that Binance is gaining market share even as overall exchange liquidity contracts.
The decline in stablecoin reserves also comes as trading activity weakens. Spot trading volume across the 10 largest centralized exchanges fell 27.9% quarter-over-quarter to $1.95 trillion in Q2, according to CoinGecko.
Despite the downturn, Binance extended its lead with a 38.7% spot market share, while Bybit reached 10.0%, overtaking MEXC.
Broader Stablecoin Supply Holds Steadier
The decline in exchange-held stablecoins has been much sharper than the drop in the overall stablecoin market. Total stablecoin supply fell from roughly $315 billion in May to $300.86 billion in August, a decline of about 4.5%, according to DeFiLlama data.
The gap suggests that some stablecoins may have moved away from centralized exchanges rather than leaving the crypto ecosystem entirely.
However, the available data does not establish how much of the decline reflects on-chain migration, self-custody or capital leaving crypto markets.
Why This Matters
Falling exchange-held stablecoins point to thinner trading liquidity, potentially making markets more sensitive to large buy or sell orders. At the same time, Binance’s growing share means stablecoin liquidity is becoming more concentrated on a single venue, increasing the market’s reliance on Binance for trading liquidity.
