Ethereum Stablecoin Supply Hits Record $166B, Dominates DeFi with Growing Institutional Trust
September 15, 2025
Ethereum's stablecoin supply has hit an all-time high of approximately $166 billion, up from $149.5 billion a month earlier, reflecting growing confidence in Ethereum's role as a core DeFi infrastructure.
Over the past week, the stablecoin supply on Ethereum increased by about $5 billion, reaching a market share of 57%, with USDT and USDC leading the expansion.
USDT remains the dominant stablecoin on Ethereum with a supply of $87.8 billion, followed by USDC at $48 billion, indicating strong liquidity and institutional trust.
Since January 2024, the stablecoin market on Ethereum has more than doubled, solidifying its position as the leading blockchain for stablecoins, far surpassing competitors like Tron and Solana.
The growth in stablecoin supply is primarily driven by USDC and USDT, suggesting increased institutional adoption and a boost in DeFi activity, which could also be supporting Ethereum's price.
Ethereum dominates the tokenized financial assets market, holding over 70% of the market for tokenized US Treasurys and establishing itself as a major hub for asset tokenization.
Experts interpret this growth as a shift from speculation to a foundational role in DeFi, with increased liquidity capable of absorbing market volatility, reflecting Ethereum's evolving ecosystem.
Nearly 4% of all ETH has been accumulated by treasury corporations over the past five months, driven by the popularity of Real World Asset (RWA) tokenization, which underscores Ethereum's credibility and neutrality.
The rise in RWA tokenization has contributed to Ethereum's price surge, which has increased over 200% since April, nearing an all-time high just below $5,000 in August.
Ethereum also reached a record-high in tokenized gold, with around $2.4 billion worth, doubling since the start of the year and dominating 77% of the tokenized commodity market, rising to 97% including Layer-2 Polygon.
Major financial institutions are actively tokenizing assets on Ethereum, exemplified by Fidelity's launch of a tokenized US Treasurys fund valued at over $203.6 million, highlighting institutional trust.
Over the weekend, USDT's market cap surpassed $170 billion, standing at $170.3 billion, emphasizing its strong market dominance and liquidity on Ethereum.
