Stablecoins: The Internet’s Default Money
Instead, the biggest story in global finance is the quiet, rapidly accelerating absorption of fiat-backed stablecoins into the actual plumbing of how the world moves money.
In 2025, stablecoins settled more transactions than Visa. Legacy giants like Mastercard, Stripe, PayPal, and Western Union didn't just experiment with stablecoins—they hardwired them into their existing consumer products. With the passage of the GENIUS Act in the United States, traditional banks finally got the regulatory green light to join the party. Yet, outside of fintech circles, almost no one noticed.
The most important upgrade to the global payments system in twenty years is happening in plain sight. Let’s break down how boring, dollar-pegged tokens became the internet's native currency, and why the traditional banking sector is scrambling to catch up.
The Numbers Behind the Invisible Revolution
To understand the scale of this shift, we need to look at the data—because the numbers tell a story that the crypto casino narratives completely miss.
By April 2026, the global supply of fiat-backed stablecoins crossed $319 billion. To put that in perspective, this is a forty-fold expansion for an asset class that barely existed before 2020. But supply only tells half the story; velocity is where the real disruption lies.
Adjusted stablecoin transaction volume grew by a staggering 91% in 2025, reaching $10.9 trillion and closing in fast on Visa’s $14.2 trillion network volume. If you look at total settlement volume across all networks, it hit $33 trillion last year—blowing past Visa’s annual throughput entirely. To put a finer point on it, stablecoins processed roughly twenty times the payment volume of PayPal.
But the most telling metric isn't the sheer size of the pie; it’s what the pie is made of.
Real-world stablecoin payments—meaning actual commercial movement of money, not just crypto traders swapping assets—doubled in 2025 to $400 billion. A massive 60% of that volume was business-to-business (B2B) payments. We are talking about multinational companies paying suppliers, settling cross-border invoices, managing corporate treasury, and running global payroll.
Stablecoins are no longer just poker chips for crypto exchanges. They have matured into the foundational operating layer of international finance. The reason this flew under the radar? It’s an aesthetic problem. Stablecoins are inherently boring. A dollar-pegged token doesn't jump 1,000% in a week. There are no screaming influencers or wild chart patterns. They are purely financial infrastructure, and the golden rule of infrastructure is that it remains invisible until it breaks—or until it replaces the old system entirely.
Why "Internet Money" Finally Works
For over a decade, crypto enthusiasts promised us "internet money." Bitcoin was supposed to be the peer-to-peer cash system. Then Ethereum was going to be the settlement layer. None of them actually worked as everyday money because the job description of a global currency is incredibly demanding. Money needs to be a reliable unit of account, universally accepted, incredibly cheap to transfer, and usable for the mundane 90% of economic life: paying rent, buying groceries, and settling invoices.
Stablecoins fit this job description perfectly. Because they are pegged 1:1 to the US dollar, they aren't speculative investments. They are simply digital dollars living on a blockchain.
When properly backed, the reserves sitting behind these tokens are held in cash and U.S. Treasury bills—the exact same financial instruments that already underpin global trust in traditional banking. But unlike traditional banking, stablecoin transactions settle in seconds, run 24/7/365, ignore weekends and bank holidays, and cross international borders without the friction of correspondent banking networks like SWIFT.
What really shifted in 2025 and 2026 wasn't a sudden leap in blockchain technology. The tech has worked for years. What changed was that the massive, highly regulated companies that actually move money for the rest of the world stopped treating stablecoins as an R&D experiment and started using them as default infrastructure.
Consider the roll call of global payment giants currently utilizing this tech:
- Visa is operating a stablecoin settlement program across nine different blockchains (including Ethereum, Solana, and Base) that hit a $7 billion annualized run rate in early 2026.
- Stripe brought back crypto payments, entirely powered by stablecoins.
- PayPal launched its own native stablecoin, PYUSD, integrating it directly alongside fiat balances in their consumer app.
- Mastercard, Western Union, Klarna, and even Meta have rolled out heavy integration plans.
A Visa cardholder in Bogotá buying lunch doesn't know—and frankly, doesn't care—that the back-end settlement between their local bank and Visa traveled as USDC on the Solana blockchain instead of moving as fiat through a clunky chain of intermediary banks. The user experience remains identical. The plumbing underneath has simply been upgraded.
The Global Duopoly: USDT vs. USDC
Right now, the stablecoin market is essentially a duopoly, dominated by two massive players with very different geopolitical and regulatory footprints.
Tether (USDT) is the undisputed king of the offshore market, with roughly $189.6 billion in circulation. It dominates emerging markets and runs the majority of remittance corridors across Latin America, Africa, and Southeast Asia. In countries battling hyperinflation or severe capital controls, USDT has become the de facto synthetic dollar.
- The Macro Impact: Tether’s massive reserve backing—which includes a staggering $113 billion position in U.S. Treasury bills as of Q1 2026—has quietly made the company one of the largest non-sovereign holders of US debt on the planet. They are essentially exporting US monetary policy to the unbanked global south.
Circle (USDC), sitting at around $77.6 billion, is the darling of institutional compliance. This is the token that Wall Street banks, payment processors, and Fortune 500 enterprises actually want to touch.
- The Compliance Edge: Circle is publicly traded, USDC’s reserves are attested monthly by Deloitte, it is fully licensed under Europe’s strict MiCA framework, and it is perfectly positioned under new US regulations. Where Tether wins on raw liquidity, Circle wins on regulatory peace of mind.
While the duopoly remains strong, a long tail of competitors is forming. PayPal’s PYUSD, Sky’s USDS, and Ripple’s RLUSD are carving out specific niches, setting the stage for a highly competitive future where major fintechs issue their own branded money.
The GENIUS Act: The Legislative Turning Point
If you want to know why 2025 was the ultimate inflection point, you have to look at Washington. The passage of the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act in July 2025 changed the calculus for every serious financial institution in the world.
For years, banks stayed on the sidelines because stablecoins lived in a legal gray area. The GENIUS Act provided the ultimate regulatory clarity by establishing three critical pillars:
- Legal Definition: It explicitly stated that permitted payment stablecoins are not securities, commodities, or traditional deposits. They are a brand-new regulated category overseen primarily by the Office of the Comptroller of the Currency (OCC), alongside the Federal Reserve and the FDIC.
- Strict Reserve Rules: Issuers are now legally required to hold 1:1 reserves in high-quality liquid assets, publish monthly audits, and adhere to strict anti-money-laundering (AML) and sanctions laws.
- The Banking On-Ramp: Most importantly, the act allowed national banks to issue their own payment stablecoins. This opened the floodgates for tokenized deposits, allowing banks that spent years watching Tether and Circle eat their lunch to finally enter the arena.
The psychological impact of the GENIUS Act cannot be overstated. Once U.S. law formally recognized the asset class, stablecoins became investable and usable for a massive tier of risk-averse institutions.
Four Real-World Use Cases Eating Traditional Finance
The theoretical promises of crypto are finally dead. In their place are four highly practical use cases operating at massive scale today:
- Cross-Border B2B Payments: This is the largest and most disruptive use case. Traditionally, a US importer paying a supplier in Vietnam relies on the SWIFT network and correspondent banks. It takes 3 to 5 days, traps capital in Nostro/Vostro accounts, and bleeds 3% to 7% in FX spreads and intermediary fees. Today, doing that same transaction via stablecoins settles in seconds for fractions of a penny. The cost-benefit ratio is so overwhelming that corporate treasury teams are abandoning legacy rails in droves.
- Consumer Remittances: In regions where local banking infrastructure is shallow or local currencies are collapsing, stablecoins are a lifeline. A migrant worker in Dubai sending money home to Lagos increasingly bypasses Western Union, sending USDT directly to a family member's digital wallet. Chainalysis data repeatedly shows this "informal" stablecoin economy scaling massively year over year.
- Card-Linked Spending: The missing link has always been the "spend" leg of the transaction. Now, companies like Rain issue Visa-network corporate cards that draw directly against a user's stablecoin balance, settling with Visa instantly. The bridge between the crypto-native dollar and the traditional merchant terminal is completely built.
- AI-to-AI Microtransactions: This is the frontier. As AI agents become more autonomous, they need to transact with one another—paying for API calls, GPU compute time, or scraping data. Traditional payment gateways like Stripe cannot handle a $0.001 transaction; the 30-cent base fee breaks the economics. Stablecoins are programmable, instant, and capable of sub-cent settlements, making them the only viable currency for the burgeoning machine-to-machine economy.
The Risks: What Could Still Break the System
It would be naive to pretend this transition is risk-free. The underlying architecture of digital money still faces massive hurdles.
- Reserve Contagion: Stablecoins are only as reliable as the assets backing them. The spectacular 2022 collapse of TerraUSD (an algorithmic, unbacked token) wiped out $40 billion and remains regulators' worst nightmare. Even fiat-backed tokens aren't immune to traditional banking crises; USDC briefly lost its peg in 2023 when its banking partner, Silicon Valley Bank, collapsed.
- The Banking Backlash: Traditional banks are growing incredibly nervous. Every dollar a consumer moves from a savings account into a stablecoin wallet is a dollar the bank can no longer lend out for mortgages or business loans. If deposit flight accelerates, expect fierce lobbying from the American Bankers Association to kneecap stablecoin issuers.
- Geopolitical Friction: Because 99% of fiat-backed stablecoins are pegged to the US dollar, they are effectively instruments of American financial hegemony. Emerging markets are already pushing back with capital controls, while China aggressively pushes its own Central Bank Digital Currency (CBDC). The EU’s digital euro project is also looming. The future of payments will be a geopolitical tug-of-war between open-network stablecoins and sovereign-controlled CBDCs.
The Bottom Line
Saying "stablecoins are eating payments" is slightly inaccurate. Payments aren't disappearing. What is actually happening is that the US dollar itself has received a massive, overdue software upgrade. It has been transformed into a new technical format that runs on open, interoperable networks, settles instantly, costs virtually nothing to move, and never sleeps.
If you zoom out, this infrastructural shift is infinitely more important than the launch of spot Bitcoin ETFs. ETFs gave Wall Street a way to speculate on crypto. Stablecoins are giving the entire global economy a fundamentally better way to use dollars.
The revolution didn't arrive with a bang. It arrived disguised as a faster settlement time on a B2B invoice, a cheaper remittance transfer to family overseas, and a Visa transaction that just worked. The internet finally got its native money, and it looks exactly like the money we already use—just vastly superior in every technical way. The next decade of traditional finance will be spent desperately trying to catch up.
