Visa Onchain Analytics' adjusted stablecoin volume hit a record $1.79 trillion in June, up 63% from May's $1.10 trillion and 125% year-over-year. Across the same four weeks, total stablecoin supply shrank by $7.7 billion, the largest monthly dollar contraction since the TerraUSD collapse in May 2022. DefiLlama places the outstanding stablecoin base near $312 billion, meaning each digital dollar rotated roughly 5.7 times in the month. USDC carried about $1.21 trillion of that total, or 67%, while Tether's USDT handled roughly $576 billion, or 32%, despite USDT's $184 billion float dwarfing USDC's $73 billion. The smaller pool is doing most of the moving.
Why it matters
Supply and volume answer different questions. Supply is the deployable cash base sitting on exchanges, in wallets, and inside DeFi contracts. Volume is the churn through that base. They can move in opposite directions, and in Q2 they did: supply fell more than $3 billion from Q1's $315 billion peak (the first quarterly contraction since Q3 2023) while adjusted volume slipped 5.5%. Yield-bearing stablecoins took the worst of it, dropping 15% and shedding over $3.5 billion, with Ethena's sUSDe losing 52% of market cap and Sky's sUSDS down 16%. Treasury-backed products went the other way, BlackRock's BUIDL up 2%, Circle's USYC gaining nearly 16%, and Ondo's USDY up 66%. Liquid deployable capital is being swapped for tokenized Treasury exposure that does not redeploy into spot risk on demand.
Market impact
Bitcoin fell 14% across Q2 and traded below $60,000, its weakest level since 2024, as stablecoin supply, spot Bitcoin ETF outflows, and slower corporate treasury buying all pulled in the same direction. US spot Bitcoin ETFs shed more than $4 billion in June, their worst monthly outflow since launch, and BTC has only recovered to around $63,000 against the $93,000 it opened the year at. Liquidity is also fragmenting: Ethereum L2s lost 24% of their stablecoin base in Q2 (Arbitrum down 45%), while HyperEVM's supply climbed 300% to $5.6 billion.
Frequently asked questions
-
Why did stablecoin supply shrink in June even as transaction volume hit a record?
Visa Onchain Analytics reported $1.79T in adjusted June stablecoin volume, up 63% from May, while supply fell $7.7B, the largest monthly contraction since the TerraUSD collapse. Yield-bearing stables fell 15%, with Ethena's sUSDe down 52%, as capital rotated into tokenized Treasury products like USYC and USDY that do…
-
How can stablecoin volume rise while supply falls?
Supply and volume answer different questions: supply is the deployable cash base, volume is the churn through it. In June each dollar rotated roughly 5.7 times, meaning the same float is being turned over faster in a smaller pool.
-
What does a shrinking stablecoin supply mean for Bitcoin price?
Stablecoins are the most accessible pool of deployable dollars in crypto. A contracting base can reduce on-chain dollar liquidity at a moment when spot Bitcoin ETF outflows exceeded $4B in June and corporate treasury buying has slowed, leaving BTC more sensitive to large orders.
-
Where are stablecoin dollars rotating instead of sitting in float?
Treasury-backed products absorbed most of the rotation in Q2: BlackRock's BUIDL added 2%, Circle's USYC gained nearly 16%, and Ondo's USDY grew more than 66%. These instruments hold T-bill exposure rather than redeploying into spot crypto trades.
-
Where is stablecoin liquidity concentrating on-chain?
HyperEVM's stablecoin supply climbed 300% in Q2 to $5.6B, Tron added $3.4B, while Ethereum L2s lost 24% of their base ($4.34B) and Arbitrum alone shed 45%. Coinbase's Base also processed about $565B in adjusted June volume, narrowly ahead of Ethereum's $562B.
