BIS Study: Dollar Stablecoins Slip Past Capital Controls, Fueling 'Digital Dollarization'

2026-07-23

The Bank for International Settlements has delivered its starkest data-driven warning yet on stablecoins' capacity to undermine one of the oldest tools in a central banker's playbook: capital controls. In a study published Tuesday, BIS researchers examined stablecoin flows across more than 130 economies and concluded that dollar-pegged tokens are "largely unaffected by either broad or specific capital flow restrictions," since they circulate partly outside the regulatory perimeter.

The research directly compared two channels by which residents of a country can gain exposure to foreign currency: traditional foreign-currency bank deposits and dollar-pegged stablecoins. According to Cointelegraph's reporting on the study, BIS researchers analyzed foreign-currency deposits and dollar-pegged stablecoin inflows across more than 130 economies, finding that both tend to increase during periods of macroeconomic stress. The divergence emerges when governments try to intervene. Unlike traditional bank deposits, stablecoin flows showed little response to capital controls or other FX restrictions.

Crypto.news, which also reviewed the findings, reported that capital controls have historically reduced some forms of deposit dollarization because banks must enforce domestic rules, but stablecoin inflows were broadly similar in economies with and without such restrictions. The outlet attributed the gap to the structural nature of the tokens themselves: digital tokens have bearer-like features and can be transferred through unhosted wallets, making complete enforcement difficult.

The BIS frames this as a new and more resilient form of "digital dollarization." Per The Block's coverage of the same report, the institution warned that policymakers in emerging markets may need to rethink their strategies as "dollarization is hard to reverse once established." The stakes are highest in economies already under currency stress. Crypto.news noted that dollar-pegged tokens could weaken monetary sovereignty if households and companies increasingly store or transact in U.S. dollars outside regulated banks, with the risk more pronounced in emerging and developing economies where inflation, currency depreciation or restricted access to foreign exchange makes dollar assets attractive.

Even blunt regulatory instruments look limited against the tokens. Crypto.news reported that the BIS Annual Economic Report 2026 noted that blocking domestic intermediaries from handling unapproved stablecoins may limit some transactions, but such measures are likely to remain imperfect.

The findings build on a broader campaign of BIS skepticism toward stablecoins that has played out over the past several weeks. In its June 2026 annual report, the institution argued that stablecoins still fall short of the core properties required of sound money — singleness, elasticity, interoperability and integrity. That report also modeled the macroeconomic effects of mass stablecoin adoption and warned of onchain illicit-finance risks tied to permissionless, pseudonymous blockchain infrastructure, according to prior coverage from The Block.

The warnings arrive as real-world stablecoin adoption keeps climbing, especially in emerging markets. Cointelegraph reported that stablecoin adoption has accelerated across Latin America, where Bitso Business, the enterprise payments arm of crypto exchange Bitso, reported an 81% year-over-year increase in stablecoin payment volume during the first half of 2026, while Circle's USDC and Tether's USDT accounted for 40% of all crypto purchases in the region in 2025, surpassing Bitcoin for the first time. Across the broader market, total stablecoin capitalization has grown to roughly $309.7 billion to $320 billion depending on the data source and cutoff date, up from about $253 billion to $260 billion a year earlier, according to figures cited by both The Block and Cointelegraph.

The BIS's own annual-report materials underscore just how concentrated that growth is in the dollar. The institution's published report noted that 99.4% of fiat-backed stablecoins by market valuation are pegged to the US dollar, leveraging the currency's role as the world's leading reserve asset. That concentration is precisely what worries BIS researchers: as regulators in the U.S., EU, Japan and elsewhere race to build dedicated licensing frameworks to bring stablecoins into the regulated financial system, the underlying tokens are already giving households in weaker-currency economies a frictionless, largely uncontrollable path into dollar exposure — a dynamic the BIS says traditional capital-control policy was never designed to handle.
