The Stablecoin Paradox: How Crypto Is Secretly Saving the US Dollar

Every few months, a BRICS summit produces the same headline. Finance ministers from Brazil, Russia, India, China, and a growing list of partner states gather, pose for photos, and announce fresh plans to trade oil, grain, and machinery in something other than dollars. Local-currency settlement mechanisms. A BRICS Pay network. Talk of a shared unit of account. The framing is always the same: the dollar’s grip on the world is loosening.

Meanwhile, in Lagos, a market trader closes out her day’s sales in naira and immediately converts most of it into USDT on her phone. In Buenos Aires, a freelancer gets paid in dollar stablecoins because nobody trusts the peso to hold its value past the weekend. In Istanbul, ordinary savers have made the Tether-lira trading pair one of the most active markets on the country’s exchanges. None of these people are attending a summit. None of them have read a communiqué about de-dollarization. They are doing the opposite of what their governments are promising, and they are doing it at a scale that dwarfs anything BRICS has managed at the state level.

That is the paradox. While the diplomatic conversation is about escaping the dollar, the technological one is about millions of ordinary people racing toward it, just not in the form of paper bills or Fed wire transfers.

The math behind this shift is not subtle. The naira lost roughly 70 percent of its value against the dollar between mid-2023 and early 2025. Argentina’s peso has shed about 95 percent of its value since 2018, with inflation hitting 211 percent in 2023 before Javier Milei’s austerity program brought it down to a still-brutal 42 percent in 2025. Turkey’s lira lost more than 450 percent of its purchasing power from 2020 to 2024. For people living through numbers like that, a savings account denominated in local currency is not a store of value. It is a countdown clock.

Stablecoins solve a narrow, practical problem for these people: how do you hold dollars when you don’t have a US bank account, can’t get access to physical cash, or live under capital controls that make it illegal or impossible to open a foreign currency account. A stablecoin is just a token on a blockchain pegged to the dollar, usually Tether’s USDT or Circle’s USDC, backed by reserves of cash and short-term Treasury bills. You don’t need a bank. You need a phone and an internet connection.

The scale this has reached is easy to undersell. The total stablecoin market now sits above $322 billion, larger than the foreign exchange reserves of 95 countries, including the UK and Canada. Transaction volume hit roughly $33 trillion in 2025, up 72 percent year over year, and by some estimates as much as two-thirds of all stablecoin supply is held in emerging markets rather than by traders in New York or London. Chainalysis puts stablecoin purchases at over half of all exchange activity for the Argentine peso. In Turkey, stablecoin purchases in 2024 alone equaled more than 4 percent of GDP, the highest ratio of any country in the world.

Some governments saw this coming and tried to build their own alternative: a central bank digital currency that would keep citizens inside the national monetary system while offering some of the same convenience. Nigeria was among the first movers, launching the eNaira in October 2021. By 2023, only about 0.5 percent of Nigerians had ever used it, and 98.5 percent of the wallets that had been opened sat completely inactive. People didn’t want a digital version of a currency they no longer trusted. They wanted digital dollars, and they found a way to get them whether or not the government approved.

This is the part that should unsettle the de-dollarization crowd. A national government can restrict access to foreign currency, close down illegal parallel markets, and lean on domestic banks to enforce capital controls. It is far harder to stop a citizen from installing a wallet app and buying USDT peer-to-peer. Nigeria has tried, at various points, to restrict crypto exchanges outright. Stablecoin volume in the country still hit an estimated $26 billion in 2024, most of it flowing through import and export financing that routes around the official, and heavily rationed, foreign exchange market.

Here is where the story gets stranger. In the United States, the GENIUS Act, passed in 2025, gave stablecoin issuers a legal framework for the first time: full backing required in cash and short-term Treasuries, registration as regulated payment instruments, anti-money-laundering compliance. Rather than slowing the trade down, regulatory clarity accelerated it. Visa began settling billions in stablecoins as part of its core operations. Stripe bought stablecoin infrastructure company Bridge for $1.1 billion. Mastercard acquired BVNK. Western Union and MoneyGram both announced their own dollar-stablecoin products, citing the new law directly as the reason they finally felt comfortable moving.

Every one of those stablecoins in circulation needs to be backed by something, and issuers like Tether and Circle now hold tens of billions of dollars in short-term US government debt to back their tokens. A Nigerian trader buying USDT to protect her savings from the naira is, indirectly, helping fund the US government’s borrowing. A Turkish saver converting lira into Tether is doing the same thing. The dollar is not just remaining the reserve currency of central banks; it is becoming the retail savings currency of hundreds of millions of individuals who have no say in, and often no interest in, American monetary policy. That is a form of dollar demand no Treasury auction or Fed policy meeting could manufacture on its own.

BRICS de-dollarization, as a project, is a top-down negotiation between states: bilateral currency swap lines, settlement systems like China’s CIPS as an alternative to SWIFT, oil contracts denominated in yuan or rupees. It is slow, politically fraught, and constantly undercut by the fact that none of the participating currencies are fully convertible or trusted as a store of value the way the dollar is. Even Brazil, a founding BRICS member, has one of the highest shares of stablecoin activity in its own crypto markets, at nearly 60 percent, just below Argentina’s.

Stablecoin adoption is the opposite: bottom-up, apolitical, driven entirely by individual decisions made under economic duress. Nobody in Lagos or Buenos Aires is buying USDT to make a statement about American power. They are buying it because the alternative is watching their savings evaporate. But the aggregate effect of millions of those individual decisions is a stronger, more entrenched dollar than any BRICS summit is capable of dismantling.

The IMF flagged this tension in a December 2025 warning, noting that dollar-pegged stablecoins could trigger currency substitution and capital outflows in already vulnerable economies. Standard Chartered estimates as much as $1 trillion could move out of emerging-market bank deposits and into stablecoins over the next three years, concentrated in countries like Pakistan and Egypt. Governments call this a risk to monetary sovereignty. From Washington’s vantage point, it looks like something closer to a second wind for the dollar’s global dominance, delivered not by the State Department or the Fed, but by a piece of open-source financial infrastructure that nobody in government actually controls.

The irony writes itself. The nations pushing hardest to escape the dollar are, at street level, producing some of its most loyal new users.
