The third quarter of 2025 marked a major milestone for the stablecoin market, a symbol of growing global adoption and ever more assertive institutional use. Driven by record DeFi activity and a clearer regulatory framework, stablecoins have reached historic highs, both in terms of supply and transaction volume, confirming their role as a central pillar of the digital economy.
In brief
- Stablecoin transfer volume reached $15.6 trillion in Q3 2025, the strongest quarter on record for digital assets.
- The total supply of stablecoins increased by $45 billion, propelling the market beyond $300 billion for the first time in its history.
- Ethereum regained its dominance with 69% of new issuance, while Tron saw a rare drop in supply.
- USDT dominated DEX trading, with over $100 billion in monthly volume, confirming the key role of stablecoins in DeFi and payments.
Ethereum regains control, Tron retreats slightly
Stablecoins reported their strongest quarter yet, with transfers exceeding $15.6 trillion and supply increasing by $45 billion. This 18% growth allowed the market to cross the historic milestone of $300 billion, according to a report from CEX.IO.
USDT, USDC and USDe led the bulk of the growth, accounting for 84% of new issuance. Despite US restrictions on yield tokens imposed by the Genius Act, USDe and PYUSD (PayPal) experienced the most spectacular gains, jumping 173% and 152% respectively. This surge is explained by the vitality of the DeFi sector and by growing use on cross-chain platforms like Stargate Hydra from LayerZero.
On-chain activity has also reached new heights, with several notable developments:
- Stablecoin transfers exceeded $15.6 trillion in Q3 2025, setting a new record.
- Automated bots generated 71% of all on-chain transactions.
- Retail activity increased, with transfers below $250 reaching record highs in September.
- Low value transactions are expected to exceed $60 billion by the end of 2025.
- Ethereum accounts for 69% of new issues, while Tron records a decline in its supply.
- Layer 2s like Arbitrum are gaining momentum, supported by demand on perpetual trading platforms and liquidity migration.
Thus, USDC's market share on Arbitrum increased from 44% to 58%, confirming the network's role as a central hub for trading and DeFi.
Layer 2 networks, like Arbitrum, have also gained traction, driven by demand from perpetual trading platforms and liquidity migration. As a result, USDC's market share on Arbitrum increased from 44% to 58%, reinforcing the network's role as a major hub for trading and DeFi.
Stablecoin ecosystem hits new highs as final quarter begins
Trading volumes across stablecoins surged to $10.3 trillion, their highest level since 2021. USDT extended its dominance, surpassing $100 billion in monthly volume on decentralized exchanges (DEX) for the first time.
It has now overtaken USDC as the most used trading pair on DEXs, boosted by the strong activity seen on the Binance Smart Chain (BSC). At the end of the third quarter, USDT's share of total trading volume increased from 77.2% to 82.5%, while USDC's share declined to 10.5%. Other stablecoins share the remaining 7% of the market.
Stablecoins solidified their central role in digital asset markets during Q3 2025. Once seen as simple liquidity tools, they have now become essential for settlements, payments and mainstream adoption. With historically high utilization heading into the fourth quarter, the industry could well post another strong quarter.
