Stablecoins are approaching money-like status as payment volumes and real-world usage grow, but experts say trust, reserves, and repeat adoption matter more than transaction volume alone. The question of whether digital dollar tokens like USDC and USDT have crossed the threshold from trading tools into genuine monetary infrastructure is no longer academic.

What Makes Something Actually Count as Money?

The numbers that would once have settled the debate are no longer settling it. Total stablecoin market capitalization stood at $291.3 billion as of July 6, 2026, with USDT and USDC together controlling 88.3% of that supply. Reported 24-hour volume across stablecoin markets reached $55.4 billion on the same date, implying an annualized run rate of more than $20 trillion.

The real milestone came in 2025. Total stablecoin settlement volume reached $33 trillion that year, surpassing Visa's annual throughput for the first time, though Visa's own adjusted methodology, which strips out trading bots and internal reshuffling, places the payment-specific figure closer to $10.2 trillion. TRM Labs recorded over $4 trillion in stablecoin transaction volume in the first seven months of 2025 alone, an 83% increase on the same period a year earlier.

At those volumes, the instruments processing the payments look less like digital tokens and more like a monetary layer. But whether they actually are one is the question that economists, regulators, and the executives building payment infrastructure on top of them are now being forced to answer.

How Do Regulators Define Payment Stablecoins?

The regulatory landscape has shifted dramatically in the past year. The GENIUS Act, signed into law in July 2025 and now in active rulemaking, established the first federal licensing framework for payment stablecoin issuers in the United States. The EU's Markets in Crypto-Assets Regulation (MiCA) took full effect on July 1, 2026. Hong Kong, Singapore, Japan, and the UAE each have purpose-built stablecoin regimes in place.

This regulatory infrastructure suggests that policymakers are treating stablecoins as something more than speculative assets. But the existence of rules doesn't automatically answer the deeper question: are these tokens actually money in the economic sense?

What Experts Say Beyond the Numbers

Economists and industry observers point to factors that go beyond raw transaction volume. Trust in the issuer, the quality and transparency of reserves backing the token, and whether users repeatedly choose to hold and spend stablecoins all matter more than a single metric. Private issuer risk remains the biggest barrier to stablecoins becoming a true monetary layer, according to experts cited in the research.

The distinction matters because money serves three core functions in an economy: it's a medium of exchange, a store of value, and a unit of account. Stablecoins excel at the first function. Whether they've truly conquered the other two is where expert opinion diverges.

Key Factors Determining Stablecoin Status as Money

• Transaction Volume and Adoption: Stablecoins processed $33 trillion in settlement volume in 2025, surpassing Visa's throughput and demonstrating widespread use as a medium of exchange across global payment networks.
• Reserve Quality and Transparency: Experts emphasize that trust in the issuer and the quality of assets backing each token are critical; users need confidence that their stablecoins can be redeemed at face value.
• Regulatory Framework: The GENIUS Act in the US, MiCA in the EU, and purpose-built regimes in Hong Kong, Singapore, Japan, and the UAE provide the legal infrastructure that elevates stablecoins from speculative tokens to regulated payment instruments.
• Repeat User Adoption: Whether individuals and businesses repeatedly choose to hold and spend stablecoins matters more than one-time transaction spikes; sustained adoption signals genuine monetary utility.
• Issuer Risk Management: Private issuer risk remains the biggest barrier to stablecoins achieving true monetary status; centralized control and potential insolvency of the issuing entity create systemic vulnerabilities.

The timing of this debate is significant. At the moment when stablecoins are processing more value than traditional payment networks, the question of whether they qualify as money is no longer theoretical. It's becoming a practical issue for central banks, financial regulators, and the institutions building the next generation of payment infrastructure.

The answer will likely shape how stablecoins are taxed, regulated, and integrated into the broader financial system over the next decade. For now, the evidence suggests stablecoins have crossed a threshold in terms of scale and real-world usage, but whether they've crossed the threshold into true monetary status remains a question that experts, regulators, and economists are still working to answer.
