BIS Warns Stablecoins Are Breaking Capital Controls as Dollarization Accelerates

A Bank for International Settlements (BIS) moving paper published successful July 2026 by BIS economists Boris Hofmann, Aaron Mehrotra, and Jan Paulick compares the emergence of stablecoins successful emerging and processing economies to “deposit dollarisation,” the long-standing signifier of holding savings successful foreign-currency slope accounts. The insubstantial draws connected information covering much than 130 economies from 1990 to 2019 for deposit dollarisation, and stablecoin travel information from Chainalysis covering 184 countries from 2017 to 2024.

Stablecoin marketplace capitalization has astir tripled since 2023, driven astir wholly by the 2 largest U.S. dollar-pegged tokens, Tether’s USDT and Circle’s USDC, according to the paper. Those 2 tokens marque up much than 80% of the full stablecoin marketplace capitalization.

Same Drivers, Different Outcomes

The researchers recovered that deposit dollarization and stablecoin inflows respond to akin economical pressures. Both emergence erstwhile a country’s speech complaint passes done powerfully into section inflation, and some ascent during fiscal crises.

One quality stood out. Banking crises are linked to higher stablecoin inflows, but not to higher deposit dollarization. Sovereign indebtedness crises amusement the other pattern, pushing up deposit dollarization by 4 to 6 percent points implicit a decade, with small effect connected stablecoin inflows.

Hofmann, Mehrotra and Paulick wrote that the banking-crisis nexus makes consciousness fixed that stablecoins run extracurricular the accepted banking system, becoming much charismatic erstwhile banks are the root of instability.

Gross stablecoin inflows comparative to GDP were fundamentally zero crossed countries successful 2019. By 2021, the median inflow roseate to astir 1.2% of GDP, with immoderate countries seeing inflows adjacent 7% of GDP. By 2023, the median had eased to astir 0.9% of GDP.

Capital Controls Don’t Reach Stablecoins

The paper’s clearest uncovering for policymakers involves regulation. Countries that necessitate support for residents to clasp foreign-currency slope accounts saw deposit dollarization ratios astir 25 to 32 percent points little than countries without those rules, based connected information from 2000 to 2016.

Stablecoins showed nary specified response. The researchers recovered nary statistically important narration betwixt restrictions connected cross-border stablecoin usage and the size of stablecoin inflows.

The insubstantial attributes this to wherever stablecoins circulate. Bank deposits beryllium wrong regulated institutions that supervisors tin scope directly. Stablecoins determination connected nationalist blockchains and tin beryllium successful unhosted wallets, extracurricular the scope of the aforesaid rules.

Dollarization Is Hard to Undo

Both forms of dollarization showed precocious persistence successful the data. Once a country’s deposit dollarization ratio rises, it tends to enactment elevated adjacent aft the ostentation oregon situation that triggered it has passed. Autoregressive estimates enactment the persistence coefficient adjacent 0.8 crossed some precocious and processing economies, a fig that has not changed since 2000.

The researchers besides looked for signs that stablecoins are simply replacing slope deposits arsenic a dollar-holding vehicle. They recovered constricted grounds of that benignant of substitution, suggesting stablecoin request successful emerging markets is coming from antithetic users, perchance younger and much tech-focused, alternatively than shifting existing dollar deposits into crypto form.

Inflation Risk Is Not a Straight Line

Using an inflation-at-risk exemplary applied to 91 emerging and processing economies, the BIS authors recovered that the narration betwixt dollarisation and ostentation is not linear. Countries with precise debased dollarization showed nary meaningful ostentation effect. Countries with mean dollarization showed somewhat higher ostentation risk crossed the distribution. Countries with the highest dollarization levels showed little ostentation risk, peculiarly astatine the precocious extremity of the distribution.

The authors picture this arsenic highly dollarized economies efficaciously importing the credibility of the U.S. dollar arsenic an anchor. The insubstantial recovered constricted grounds that dollarization changes however monetary argumentation shocks walk done to growth, inflation, oregon speech rates.

What Comes Next

The authors caution that stablecoin adoption whitethorn not support expanding astatine its caller pace, and that lessons from decades of slope dollarization whitethorn not afloat use to a strategy built to run extracurricular supervised finance. Still, the insubstantial argues that if stablecoin maturation successful emerging markets continues, cardinal banks and concern ministries look a transmission for U.S. dollar vulnerability that existing capital-flow tools were not built to manage.
