Stablecoin Supply Slides $10B as U.S. Stocks Pull Fresh Capital

Highlights:

• Stablecoin supply has dropped by about $10 billion, with USDT and USDC leading the decline.
• USD1 added $500 million, helped by exchange incentives and active trading campaigns.
• Ethereum holds 87% of stablecoin liquidity, keeping the deepest on-chain base.

The stablecoin market has lost $10 billion in recent months as traders moved capital away from crypto liquidity pools. The decline pulled the total market back toward $300 billion, according to the figures cited by EmberCN on July 4. Meanwhile, U.S. equities attracted stronger inflows as investors chased better returns during a difficult crypto stretch.

The move marks one of the clearest liquidity shifts from last year. Stablecoins often show where crypto capital sits before it enters risk assets. Therefore, a shrinking supply usually points to weaker buying power across exchanges, DeFi venues, and on-chain markets.

Stablecoin Supply Slides as USDT and USDC Shrink

Tether’s USDT and Circle’s USDC carried most of the decline. USDT fell from $189.8 billion to $184.1 billion, reflecting an outflow of $5.7 billion. USDC dropped further, sliding from $79.6 billion to $73.0 billion, which removed $6.6 billion from circulation. Circle’s USDC decline came as the shares lost momentum. CRCL fell from around $136 to about $64 after growth expectations cooled alongside lower USDC supply.

加密市场今年整整跌了半年了，所以美元稳定币整体市值是有所减少的，减少了约 $100 亿到现在 $3,000 亿的总市值。流出的资金则去了美股这个今年更具造富效应的市场。

Together, those shifts explain most of the contraction. Both tokens still dominate dollar-based crypto liquidity. However, their supply losses show that large holders reduced stablecoin exposure during the market downturn.

USD1 Grows as Incentive Programs Support Usage

USD1 moved against the wider market trend. Its supply increased from $4.1 billion to $4.6 billion, increasing by approximately $500 million during the same period. The rise helped the token have rare growth momentum as larger stablecoins saw their market share drop.

However, exchange incentives appear to be a significant part of that growth. Several centralized exchanges have been providing benefits, such as rewards, yield support, or account benefits tied to USD1 holdings. Therefore, users gained a direct reason to hold the token, even as broader crypto liquidity weakened.

The next test centers on daily usage. Stablecoins need more than holders to become important settlement assets. They need payment flows, trading pairs, DeFi pools, and regular transfers. As a result, incentive campaigns now push users toward actual activity rather than passive balances.

Meanwhile, Binance has already pushed USD1 toward active use. Its campaign requires open positions in USD1 contract pairs to unlock higher rewards. The structure is intended to build habits around the token, not just parked balances. USD1 could hold its market gains over the short-term subsidies if usage increases.

Ethereum Keeps a Firm Grip on Stablecoin Liquidity

Market data also shows Ethereum holding a dominant stablecoin position. According to data from Artemis, Ethereum’s share of total stablecoin supply stands at 87%. That figure shows its continuing lead over Solana, Polygon, Avalanche, BNB Chain, Tron, and other networks.

The dominance reflects where issuers, market makers, and institutions continue to find deeper liquidity. Ethereum also supports large DeFi markets, tokenized asset flows, and institutional settlement activity. As a result, stablecoin capital keeps clustering around the chain with the broadest existing network.

This consolidation provides a self-reinforcing cycle. An increase in liquidity promotes more issuance, while higher issuance delivers more liquidity depth. At the same time, rival chains compete for a smaller share, despite having faster speeds or lower transaction costs.
