Stablecoins in 2026: How the GENIUS Act Changed Everything
The stablecoin market entered 2026 as a different place than it was two years ago. Not because the technology changed, but because the legal framework around it did.
The GENIUS Act, signed into law on July 18, 2025, established the first federal framework for dollar-backed stablecoins in the United States. The effects are still propagating through the market.
The Stablecoin Market Before the GENIUS Act
Prior to 2025, stablecoins operated in a regulatory grey area in the US. Tether (USDT) dominated the market with no US regulatory oversight and reserves that had been questioned by researchers and regulators for years. USDC, issued by Circle, had pursued a more transparent approach with regular attestations, but without a clear legal framework, both operated under the same absence of formal rules.
The market grew regardless. Stablecoin transaction volumes reached $33 trillion in 2025, a 72% increase from the prior year. USDC alone accounted for $18.3 trillion of that volume.
The growth reflected genuine utility. Stablecoins had become infrastructure for crypto trading, DeFi, cross-border payments, and increasingly for corporate treasury operations in regions with volatile local currencies.
What the GENIUS Act Requires
The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act established several key requirements for dollar-backed stablecoin issuers operating in the US.
Issuers must maintain 1:1 reserves in US dollars or approved high-quality liquid assets. They must undergo regular audits and report reserves publicly. They must be registered and supervised either federally or by a qualifying state framework. Foreign issuers serving US customers face equivalent requirements.
The intent was to make stablecoins formally safe for US institutional use - removing the legal uncertainty that had kept many regulated entities on the sidelines.
The USDT vs USDC Divide
The GENIUS Act created a clearer divide between the two dominant stablecoin issuers than had existed previously.
USDC grew 73% in 2025 to a market cap of $75.12 billion. Circle positioned USDC as the GENIUS Act-compliant choice, and institutional demand responded. The $18.3 trillion in transaction volume driven by USDC reflects significant adoption in regulated and institutional contexts.
USDT grew 36% to $186.6 billion - still the larger coin by market cap, but growing more slowly, and still without US or European regulatory approval. Capital has been rotating toward GENIUS Act-compliant stablecoins as regulated entities seek assets that fit within their compliance frameworks.
Both Tether and Circle became significant buyers of US Treasury holdings as a result of their reserve requirements and voluntary commitments - together purchasing $56.6 billion in Treasuries, making stablecoin issuers relevant actors in sovereign debt markets.
For users who want to hold or trade stablecoins, platforms like Binance support both USDT and USDC trading pairs across hundreds of markets.
Global Ripple Effects
The GENIUS Act did not exist in isolation. It joined a set of frameworks emerging simultaneously in other jurisdictions.
The EU's Markets in Crypto-Assets (MiCA) regulation, which took full effect in 2025, established similar reserve and reporting requirements for stablecoin issuers operating in Europe. MiCA has already limited the availability of non-compliant stablecoins on EU-based exchanges.
Hong Kong introduced its own stablecoin licensing regime in early 2026, requiring local licensing for HKD and USD-pegged stablecoins distributed there. Singapore's MAS has updated its Payment Services Act framework along similar lines.
Dollar-pegged stablecoins continue to dominate the global market at approximately 98% of the $300 billion total, but the regulatory frameworks shaping which stablecoins are accessible in which markets are increasingly divergent.
Practical Differences for Crypto Users
For most individual crypto users, the day-to-day experience of using stablecoins has not changed dramatically. Both USDT and USDC remain widely accessible, liquid, and functional as trading collateral and settlement assets.
The differences matter more at institutional scale and for users in regulated environments. A hedge fund or fintech company operating under regulatory oversight may find that USDC fits within compliance frameworks that USDT does not. A retail user trading on a global exchange will likely find both available and functionally equivalent for most purposes.
The longer-term trajectory of the market appears to favor compliance. As more institutions enter the stablecoin space and more jurisdictions establish clear frameworks, issuers operating without regulatory approval will face increasing pressure either to comply or to lose access to regulated distribution channels.
The GENIUS Act established the baseline. The years that follow will determine how the market reorganizes around it.
