The total market capitalization of stablecoins hit a record $322 billion this week, with Tether and Circle controlling more than 80% of the circulating supply. Western Union pushed deeper into the space by launching its own US dollar-denominated payment stablecoin, USDPT, issued by Anchorage Digital Bank on the Solana network. The move signals that established money-transfer giants now see blockchain-based dollars as essential infrastructure.
$322 billion and climbing
USDT alone accounts for nearly 59% of the $322 billion pool, according to public blockchain data. Ethereum and Tron process the vast majority of outstanding stablecoin token balances. Aggressive forecasts project the sector could scale into a multi-trillion-dollar market by the end of the decade, driven by real-time settlement and borderless transfers that go far beyond crypto trading.
Payment companies like Payoneer already treat stablecoins as commercial plumbing for global money transfers. The infrastructure is no longer experimental — it's being woven into the backbone of cross-border finance.
Western Union's USDPT play
Western Union's new token, USDPT, is backed by bank deposits and Treasury bills. It runs on Solana, a chain chosen for speed and low transaction costs. Anchorage Digital Bank, a federally chartered crypto bank, handles issuance. The token is purpose-built for payment flows, competing directly with offerings from Tether and Circle while borrowing legitimacy from traditional banking rails.
The timing isn't accidental. As stablecoin volumes swell, Western Union — a company that moved $200 billion in cross-border payments last year — is hedging against disruption by joining it.
The private money warning label
The boom has revived warnings about privately issued money. A Wall Street Journal analysis compared today's stablecoin landscape to 1800s-era 'private money' vulnerabilities, when banknotes from different issuers traded at varying discounts and sometimes became worthless.
Coinbase Chief Policy Officer Faryar Shirzad pushed back, arguing that private money already makes up roughly 90% of the M2 money supply in the form of bank deposits and money market funds. The real regulatory focus, he said, should be on structural guardrails rather than on banning private issuance.
What the GENIUS Act tries to fix
The federal GENIUS Act is the most concrete regulatory framework on the table. It aims to set reserve requirements, disclosure standards, and oversight for stablecoin issuers — addressing the exact concerns the WSJ piece raised. The bill doesn't ban private stablecoins; it tries to make them safer. Whether it passes in its current form is an open question, but the debate is no longer theoretical.
Banks fight back with tokenized deposits
Traditional banks aren't sitting still. In response to stablecoin competition, several large institutions are deploying tokenized deposit systems that route trillions of dollars annually through blockchain infrastructure. These are essentially bank-issued digital dollars that live on a distributed ledger but remain inside the regulated banking system. The battle between deposit tokens and independent stablecoins is only beginning.
Next up: Congress returns from recess next week, and the GENIUS Act markup session is expected to draw fresh lobbying from both camps. The outcome will shape whether stablecoins remain a fringe tool or become the default dollar rail for a generation.
