Stablecoin supply shrinks $10B since May peak as liquidity tightens

The stablecoin market has shed roughly $10 billion since May, the steepest dollar decline since the Terra collapse, as redemptions in Tether and Circle tokens drained onchain buying power.

The combined circulating supply of Tether's USDT and Circle's USDC has fallen by roughly $10 billion from their May peak, with the broader stablecoin market contracting 3% over the same stretch, onchain data from DefiLlama shows.

"The recent decline in stablecoin market cap represents a relatively small pullback in what we believe is a long-term growth market," Paul Howard, senior director at trading firm Wincent, said. "Short-term fluctuations in liquidity are normal, but they don't change our view that stablecoins will continue to play an increasingly important role in the digital asset ecosystem."

June alone saw a $7.7 billion contraction, the largest monthly dollar decline since the TerraUSD implosion in May 2022, according to RWA.xyz data. USDT's market capitalization slipped to roughly $184 billion from $190 billion in May, a drop of about $6 billion, while USDC declined to around $73 billion from a March peak near $80 billion, shedding nearly $7 billion over four months. On a percentage basis, the 3% pullback remains far smaller than the 26% contraction during the 2022 bear market.

The supply reduction removes a tailwind for crypto markets, as stablecoins serve as the primary quote currency for trading and a proxy for onchain liquidity. Transaction volumes remained elevated at a record $1.78 trillion in June, suggesting the decline reflects capital rotation rather than a structural exodus, but further monthly contractions would signal that buying power is leaving the system.

The retreat has been concentrated in the two dominant issuers, but the competitive landscape is shifting. Newer regulated entrants expanded even as USDT and USDC shrank. Global Dollar (USDG), issued by Paxos and backed by a consortium including Robinhood, surpassed $3.2 billion in circulation, while USDGO, issued by Anchorage Digital with Hong Kong's OSL Group, nearly doubled to $900 million, CoinGecko data shows.

The U.S. GENIUS Act, signed into law last year, created a federal framework for payment stablecoins, opening the door for more regulated competitors. OpenUSD, backed by a group of payments and financial firms, is among several newcomers preparing to challenge the dominance of USDT and USDC.

Tokenized real-world assets moved in the opposite direction, with onchain value crossing $30 billion during 2026, led by Treasury products and private credit. Tokenized equity trading volume rose 145 percent in June to a record $3.86 billion, CoinDesk Research data shows.

The supply figures point to a pause in market expansion rather than a Terra-style collapse. USDT and USDC remain near their dollar pegs, transaction activity remains high, and the total market retains most of its recent growth. Investors will watch July issuance and redemption data for signs that demand is returning or weakening further.
