BIS Warns Stablecoins Bypass Capital Controls, Accelerate Digital Dollarization in Emerging Markets

Headline: BIS: Stablecoins Are Sidestepping Capital Controls — A Growing Headache for Emerging Markets The Bank for International Settlements has flagged a major loophole in how emerging-market economies try to protect their currencies: dollar-backed stablecoins. BIS researchers examined inflows of dollar-pegged tokens across more than 130 countries and found they largely ignore the capital controls that still limit traditional foreign-currency bank deposits. The result: a new, blockchain-enabled channel for “digital dollarization” that may erode monetary sovereignty and complicate policy. What the BIS found - Stablecoin inflows rise in the same stress conditions that drive demand for U.S. dollars — sovereign crises, banking troubles, and sharp exchange-rate pass-through — but unlike bank deposits, they are not meaningfully curtailed by restrictions on foreign currency or capital flows. - The key difference is technical and legal: bank deposits typically must flow through regulated financial institutions subject to domestic rules, while stablecoins can move via centralized exchanges, peer-to-peer markets and self-hosted (unhosted) wallets without passing through banks. In short, stablecoins are partly circulating outside the regulatory perimeter. - Once households and firms start using foreign-currency deposits or stablecoins, the behavior tends to persist. The BIS found little evidence that users simply shift deposits into stablecoins as a one-for-one substitution; instead both channels can expand simultaneously, amplifying dollarization pressure. - Although deposit dollarization at moderate levels does not appear to drastically weaken monetary-policy transmission, economies with larger shares of foreign-currency deposits show somewhat higher inflation risks. Stablecoins are potentially more disruptive because their use goes beyond savings into payments, trade settlement and remittances — and transactions that occur outside the banking system also escape the reporting and monitoring tools regulators rely on. Why capital controls struggle Traditional capital controls work because banks and other intermediaries enforce them. Stablecoins, however, resemble bearer instruments: they can be stored in self-custodied wallets and transferred on-chain or via unregulated platforms, making comprehensive enforcement difficult. Blocking domestic intermediaries from handling unapproved stablecoins can limit activity, the BIS says, but such measures are likely to remain imperfect unless regulators address the blockchain-native channels themselves. Real-world examples - Nigeria: The IMF reported stablecoins made up more than 65% of the country’s cross-border crypto inflows in 2024, with total inflows nearing the value of recorded remittances by 2025. Nigerians have increasingly used USDT and USDC for remittances, crypto investments and dollar access; small and medium importers have paid foreign suppliers with tokens, and some large firms experimented with them for trade settlement. Tighter bank rules in 2021 pushed users toward peer-to-peer markets rather than stopping usage. - Latin America: Regional crypto payment activity is accelerating — Bitso Business recorded an 81% year-over-year increase in stablecoin payment volume in H1 2026. In 2025, USDT and USDC made up around 40% of crypto purchases in the region, surpassing Bitcoin for the first time. Market context and scale - Stablecoin market capitalization has swelled to roughly $309.7 billion, up from about $260 billion a year earlier — giving dollar-pegged tokens growing influence as instruments for payments and savings and heightening the urgency of regulatory responses. Policy options and the limits of old tools The BIS’ analysis suggests that simply extending capital-control rules designed for bank deposits will not be enough. Policymakers may need tools tailored to blockchain-based assets that take into account: - foreign cryptocurrency exchanges, - peer-to-peer transfers, and - self-hosted wallets. The BIS also contrasts privately issued stablecoins with tokenized bank money. Project Agorá — an initiative involving eight central banks and over 40 regulated institutions — has tested cross-border settlement with tokenized commercial-bank deposits and central-bank reserves. That model keeps tokenized payments inside the regulated two-tier banking system, which helps preserve oversight and control in ways stablecoins currently do not. Why it matters for emerging markets For countries battling high inflation, currency depreciation or restricted foreign-exchange access, stablecoins can look like a lifeline: faster payments, cheaper remittances and an easier route to dollar access. But widespread use of dollar-pegged tokens can reduce demand for local currency, push transactions outside regulatory view, and limit the effectiveness of monetary policy — a combination that poses a potent challenge for many developing economies. Bottom line Stablecoins are creating a parallel dollar channel that capital controls — as currently enforced through banks — struggle to plug. Regulators face a choice: adapt rules and monitoring to the realities of decentralized finance, or accept that dollarization may increasingly migrate to blockchain rails beyond the reach of traditional tools.
