USDT and USDC Drive the Stablecoin Market Decline
The main reason behind the decline is the fact that investors are cashing out of the two largest stablecoins, Tether (USDT) and Circle’s USDC. The current figures appear to be a temporary slowdown rather than a major sell-off. Both stablecoins still maintain their $1 peg, and blockchain activity remains strong.
Leading Stablecoins Lose Billions as Liquidity Tightens
USDT and USDC, the leading stablecoins, have both experienced declines: USDT supply has fallen from a peak of $190 billion in May to around $184.15 billion. At the same time, USDC has continued its four-month decline, dropping from $80 billion in March to $73.41 billion.
Even after the loss, Tether still accounts for nearly 59% of the stablecoin market. Together with USDC, they make up more than 82% of the entire sector.
Investors prefer stablecoins for moving money into and inside the crypto market. The shrinkage in their supply suggests that there is less readily available capital to buy major cryptocurrencies, such as Bitcoin and Ethereum.
Stablecoin Activity Remains Strong Despite Lower Supply
The decline in the liquidity of stablecoins, as seen in DefiLlama data, is part of a broader regression in institutional crypto investments. Due to the shrinking of institutional capital and on-chain dollar liquidity, the market was under pressure throughout June. However, it is important to note that this decline in stablecoin supply was not accompanied by slower blockchain activity.
Moreover, the fact that adjusted stablecoin transaction volume reached a record figure of $1.78 trillion in June shows that the stablecoins that remain in circulation are being used more actively:
- Circle’s USDC: Widely used by institutions and decentralized finance (DeFi) platforms, USDC processed about $1.21 trillion in transaction volume during June.
- Tether’s USDT: USDT handled roughly $573 billion in transaction volume but recorded a larger number of individual transfers. This suggests that although fewer USDT tokens are circulating, they are changing hands more frequently for everyday payments, trading, and transfers across crypto exchanges.
Investors Turn to Yield-Bearing Tokenized Assets
Another important observation regarding the shrinking in stablecoins is that investors are moving money into more sophisticated, yield-generating tokenized assets. Due to the high demand for tokenized US Treasuries, private credit, and investment funds, the total value of on-chain real-world assets (RWAs) exceeded $30 billion in 2026 so far.
Tokenized equities also experienced growth: trading volume increased by 145% in June alone, reaching a record $3.86 billion. These figures are important since they suggest capital is not necessarily leaving the blockchain. Instead, many investors are exploring the opportunities offered by tokenized assets.
July Data to Reveal Whether Stablecoin Slowdown Is Temporary
The recent slowdown has taken place in a regulatory environment that is becoming more clear for stablecoin, with the passage of the GENIUS Act in the US creating the first federal framework specifically for this asset class. Moreover, regulators are seeking to establish detailed rules regarding customer verification, sanctions compliance, and reserve management.
Market participants are now waiting for July’s issuance and redemption data, along with crypto exchange trading volumes and spot ETF flows. These indicators are expected to clarify whether June’s $10 billion decline in stablecoin supply was simply a temporary slowdown, or the beginning of a longer period of lowered stablecoin investments.
