A vendor in Lagos gets paid in USDC because the naira is rationed and the parallel market is where the real exchange rate lives. A treasurer in Bentonville is exploring a Walmart-branded stablecoin because wire fees and interchange are a drag on margin. A bank consortium in New York is racing to launch a joint token because JPMorgan, Citi and eighteen others would rather cannibalise their own float income than watch a tech platform do it first. None of these three people think of themselves as participants in a currency war. All three are.
That is the part of the stablecoin story that keeps getting lost under the payments-innovation framing. Stablecoins crossed roughly $300 billion in circulating value this year, stablecoin settlement volume has now overtaken the ACH network, and the passage of the GENIUS Act in the United States gave the asset class something crypto has wanted for a decade: a legal home inside the regulated financial system. Every one of those facts gets reported as a fintech milestone. Almost none of them gets reported for what it actually is, which is the most effective distribution mechanism the US dollar has had in fifty years, and one that corporate treasurers are helping build without being asked whether they want to.
The plumbing is the point
Strip away the crypto vocabulary and a dollar stablecoin is simple: a digital claim on a dollar, fully reserved, transferable peer-to-peer, and settled outside the correspondent banking system that has historically been where governments exercise control over cross-border money movement. That last clause is the one worth sitting with. Correspondent banking is slow and expensive partly because it is also where sanctions get enforced, where capital controls get applied, and where central banks retain some visibility into what is leaving their currency and going where. A stablecoin transfer does the same economic job as a wire, at a fraction of the cost and settlement time, while sitting largely outside that perimeter.
The Bank for International Settlements made this explicit in research this year covering more than 130 economies: stablecoin inflows rise during periods of currency stress in the same way foreign-currency bank deposits do, but unlike those deposits, stablecoin flows show almost no sensitivity to capital controls or FX restrictions. In Nigeria, households and small businesses now use dollar-pegged tokens routinely for remittances and cross-border payments precisely because naira depreciation and dollar scarcity make the official channel unusable. Across Latin America, stablecoin payment volume through business platforms grew roughly 80% year-on-year in the first half of 2026, and USDC and USDT between them now account for a larger share of regional crypto purchases than Bitcoin. This is not speculative trading. It is a currency substituting for another currency, transaction by transaction, in exactly the economies whose central banks can least afford it.
Call it what the BIS calls it: digital dollarisation. It doesn’t require a policy decision in Washington, a trade agreement, or a reserve-currency mandate. It only requires that a stablecoin work well enough that people prefer it to their own money. Rabi Sankar, deputy governor of the Reserve Bank of India, put the danger more bluntly than most central bankers are willing to: the threat, he has argued, is greatest precisely when the stablecoin functions as designed, because that is when it displaces the local currency fastest.
Every CFO chasing efficiency is also placing a geopolitical bet
None of this makes the corporate logic for adopting stablecoins irrational. An EY-Parthenon survey this year found that companies already using stablecoins for payments report cost savings above 10%, and more than half of non-adopters expect to start within a year. For a multinational moving supplier payments across a dozen currency corridors, that is a real, defensible number, and finance chiefs are right to chase it.
What most of them haven’t priced is that adopting a dollar-denominated settlement rail is not a neutral technology choice in the way switching ERP vendors is. It is a decision that changes whose monetary policy your treasury is most exposed to, and it changes what your local subsidiaries look like to the regulators who oversee them. A company that believes it is fully compliant with a host country’s capital controls may already be operating inside an ecosystem, among its distributors, gig workers and smaller vendors, that has quietly dollarised beneath it. That gap is invisible until the local central bank decides to close it, and several are now signalling they will. When that happens, the disruption lands on exactly the supply chain the treasury thought it had de-risked.
The largest corporates are making an even bigger bet by trying to issue their own tokens. Walmart, Amazon and a widening circle of retailers have explored branded stablecoins explicitly to route around interchange fees paid to Visa and Mastercard. That is a rational fight to have. But a retailer that issues a dollar-backed liability against its own balance sheet has taken on a version of what banks do, reserve management, redemption risk, run risk, without the regulatory infrastructure or the decades of supervisory relationships banks have built to survive a bad week. The upside is real. So is the fact that nobody has stress-tested a retail-issued stablecoin through an actual liquidity event.
India’s contrarian bet, and why it isn’t a lag
This is where India’s posture becomes genuinely interesting rather than merely defensive. The RBI has been unambiguous in rejecting the GENIUS Act framework as a template, characterising privately issued stablecoins as inherently unstable money and pushing instead toward the digital rupee alongside the existing UPI rail, which is now being interlinked with payment systems in the eurozone and elsewhere to extend its reach without ever touching a dollar-denominated token. It is tempting to read this as India sitting out a wave the US, EU and a growing share of emerging-market fintech are riding. The more accurate read is that India solved the problem stablecoins are pitched as solving, cheap, instant, low-friction payments, through UPI years ago, domestically and largely for free. A country that already has a fast, sovereign, nearly costless payment rail has structurally less reason to import a dollar-linked one that comes attached to a foreign central bank’s monetary policy. Nigeria and Argentina are dollarising through stablecoins because their own currencies and payment systems are failing their citizens. India’s rail isn’t failing, which is precisely why the RBI can afford to say no.
That doesn’t make India’s bet costless. Multinational treasuries operating in India won’t get the same stablecoin-driven cost efficiencies their US and European peers are booking, at least not onshore, and Indian corporates expanding abroad will need to run dual playbooks, UPI-style rails at home, dollar stablecoin exposure wherever their counterparties demand it.
What this actually asks of the people running these companies
The stablecoin question in front of most executive teams right now is framed as a payments-efficiency decision: which rail is cheapest, fastest, easiest to integrate. That framing will produce the wrong analysis. The right question is where, across the balance sheet and the supply chain, a company is already exposed to a rail that sits outside a host government’s monetary control, whether by treasury design or by the unpoliced habits of vendors and employees three tiers down, and what happens to that exposure the day a central bank decides digital dollarisation has gone far enough. Regulatory tightening in the economies where stablecoin substitution is furthest along, Nigeria and much of Latin America among them, is now a matter of when rather than if. The companies that treated stablecoin adoption as a currency and jurisdiction decision, not just a treasury upgrade, will be the ones not caught flat-footed when it comes.
