Stablecoin Capitalization Surpasses $300 Billion

The total market capitalization of stablecoins has surpassed $300 billion for the first time in history this week. The Genius Act and SEC accounting guidelines have significantly increased confidence in stablecoin tokens.

This, in turn, has spurred institutional and retail adoption in 2025.

$300 Billion Milestone

According to DeFiLlama, Tether (USDT) remains the dominant stablecoin, holding 58.52% of the market with an estimated $176.241 billion. Following is Circle’s USD Coin (USDC) with a market capitalization exceeding $74 billion, while USDe, the third-largest yield-generating stablecoin, holds $14.83 billion.

The milestone indicates the growing importance of stablecoins within the broader cryptocurrency ecosystem, coming amid a recovery of the entire market after a volatile week.

Historically, the third quarter is quieter for cryptocurrencies, but 2025 has reversed that trend and ultimately become a record period for stablecoins. Activity has increased due to regulatory clarity and growing user engagement. A report from Cex.io revealed that Google searches for ‘stablecoin’ surged following significant announcements.

For instance, the U.S. passed the Genius Act, while the Securities and Exchange Commission (SEC) issued new accounting guidelines that classify dollar-pegged stablecoins as cash equivalents. These regulatory movements have bolstered confidence among institutional and retail participants.

Impact on the Global Role of the Dollar

The rapid growth of the stablecoin market significantly impacts the global role of the U.S. dollar, believes John Murillo, Chief Business Officer of B2BROKER. Murillo stated that this increase is partly due to last month’s slow momentum in major cryptocurrencies like Bitcoin and Ethereum, prompting investors and users to turn to dollar-pegged stablecoins.

– The global footprint of the U.S. dollar has certainly deepened with stablecoins, as about 98% are directly or indirectly pegged to the dollar. This has, for better or worse, embedded the dollar into decentralized finance, cross-border payments, while helping stabilize many economies affected by inflation. In regions like Nigeria and Venezuela, digital dollars now circulate more freely than local currencies, expanding the dollar’s dominance in the digital realm – Murillo stated.

However, Murillo warns that this growth carries systemic risks. He added that stablecoins typically operate outside conventional banking regulations, raising questions about reserve transparency, liquidity vulnerabilities, and regulatory gaps. A sudden loss of confidence, whether due to unclear backing or platform failures, could indeed destabilize both crypto markets and traditional fiat systems.

Moreover, as stablecoins increasingly operate within decentralized networks, they begin to function independently of U.S. institutions, potentially limiting Washington’s direct control over monetary influence.

– The dollar remains dominant in form, but is increasingly challenged in function – he added.

Stablecoins Now Larger than Visa or Mastercard

The volume of stablecoin transfers has surged from just $3.3 billion in 2018 to $18.4 trillion in 2024, surpassing Visa at $15.7 trillion and Mastercard at $9.8 trillion. This represents one of the fastest adoption curves in financial history, as evidenced by the annual transfer volumes of Visa and Mastercard.

Visa’s annual transfer volume gradually increased from about $11.3 trillion in 2018 to $15.7 trillion in 2024, while Mastercard rose from $5.9 trillion to $9.8 trillion during the same period.

Since 2018, stablecoins have recorded two significant increases in transfer volume. The first occurred between 2020 and 2021 when volumes increased nearly sixfold, from $1.3 trillion to $8.1 trillion the following year.

The second increase was from 2023 to 2024, when volumes more than doubled from $7.6 trillion in 2023 to $18.4 trillion the following year.

Visa and Mastercard have also consistently grown, but at a much slower pace. Visa increased from $11.3 trillion in 2018 to $15.7 trillion in 2024, while Mastercard grew from $5.9 trillion to $9.8 trillion during the same period.
