In 2025, stablecoins handled about $35 trillion in transactions, but almost all of it was crypto trading, not real-world payments such as payroll.
That gap explains why stablecoins are getting more attention in 2026. They’re already huge inside crypto, but lawmakers and payment companies are now asking whether blockchain-based dollars can become a larger part of everyday money movement.
Here’s how stablecoins moved from trading tools into payment infrastructure, and what new U.S. rules could change for users and businesses.
What U.S. Lawmakers Are Proposing
The big question in Washington is simple: if a stablecoin works like a digital dollar, who should regulate it?
The U.S. Senate passed the GENIUS Act in June 2025 by a 68–30 vote, setting up the first major set of federal rules for stablecoins, which are crypto tokens usually tied to the U.S. dollar. The bill focuses on setting boundaries and protecting everyday users of stablecoins.
In plain English, lawmakers want stablecoin companies to prove three things: their tokens are backed, users can redeem them, and issuers can spot and flag illegal money activity.
That changes the stablecoin debate. Washington isn’t treating them only as crypto trading tools anymore. It’s treating them as part of the payment system.
Why Stablecoins Matter Beyond Crypto Trading
For many people outside crypto, stablecoins still sound niche. But the idea is simple.
A stablecoin is a digital token tied to the value of a traditional currency, usually the U.S. dollar. Instead of moving through a bank’s internal system, it moves on a blockchain, which is basically a shared online record that tracks transactions.
We can think of stablecoins as digital dollars that move on blockchain networks instead of traditional banking systems.
That makes them useful beyond trading. They can send money across borders, move funds even when banks are closed, and help companies pay suppliers faster. For a business paying suppliers overseas, that speed can matter. For a worker getting paid across countries, it can matter too.
But the payment story needs context. McKinsey said reported stablecoin transaction volumes reached up to $35 trillion annually, but much of that activity came from trading, money moving between crypto platforms, and automated transactions rather than actual people making real payments.
Payment companies are still watching the space for a clear reason. U.S. merchants paid $187.20 billion in processing fees to accept credit and debit cards in 2024, up 8.7% from 2023, according to The Nilson Report.
Why Regulators Are Paying Closer Attention
Regulators tend to move when a product starts touching more than one market. Stablecoins now touch crypto trading, payments, banking, checks for illegal money movement, and consumer protection.
Scale is one concern. DefiLlama tracks the total stablecoin market at about $322.9 billion. with Tether’s USDT holding about 58.71% dominance. USDT is Tether’s dollar-linked stablecoin.
When a few private companies issue digital dollars used across exchanges, apps, and payment networks, regulators want to know what happens if one issuer fails. They also want to know whether users can cash out their tokens quickly if things go wrong.
Which Stablecoins Could Be Most Affected
The biggest stablecoins will likely face the most attention.
USDT, issued by Tether, is the biggest stablecoin by market value. DefiLlama lists Tether’s market cap at about $189.6 billion, which makes it central to any stablecoin regulation debate.
USDC, issued by Circle, is another major dollar-linked stablecoin. It’s often discussed in U.S. regulatory conversations because Circle has focused on following rules, being open about its reserves, and working closely with traditional banks.
PayPal USD, or PYUSD, is smaller but important. PayPal is a mainstream payments company, not only a crypto-native platform. That makes PYUSD a useful example of how stablecoins could move from exchanges into broader payment apps.
We shouldn’t rank these tokens or tell readers which one to use. The useful takeaway is that size, proof of backing (meaning whether the company can prove it actually holds the money backing each token), and how well a stablecoin follows the rules now matter more than just the name behind it.
What This Could Mean for Crypto Users and Payments
For you, clearer stablecoin rules could bring more trust and more checks.
The upside is straightforward. If issuers must prove reserves, follow redemption rules, and meet compliance standards, payment companies may feel safer building stablecoin products. That could mean faster international transfers, cheaper ways to pay online, and more businesses accepting digital dollars.
But there’s a trade-off. More regulation usually brings more identity checks, more reporting, and less room for loosely supervised products.
Some users will see that as a fair exchange for safer payment tools. Others will see it as crypto becoming closer to the banking system it once tried to avoid.
The Biggest Risks Around Stablecoins
Stablecoins aren’t risk-free just because they’re designed to stay near $1. The biggest risks come from how they’re backed, controlled, regulated, and connected to the traditional financial system.
- Proof of backing: A stablecoin only works as a digital dollar if users trust the assets behind it. If that trust breaks, users may rush to redeem their tokens.
- Control: Many large stablecoins are controlled by one company, a small group of banks, and a handful of storage providers. That can make them efficient, but it also creates clear points of control.
- Conflicting rules across countries: The U.S., Europe, Asia, and other markets may create different rulebooks. Since stablecoins move globally, mismatched rules could make things harder for stablecoin companies and more confusing for everyday users.
