Plans to issue stablecoins denominated in local currencies to reduce reliance on dollar-linked tokens may unintentionally make it easier to move value into “digital dollars,” according to a senior International Monetary Fund (IMF) official.
Speaking on Friday, IMF First Deputy Managing Director Dan Katz said that once local- and dollar-denominated stablecoins run on the same underlying blockchain infrastructure, users could swap between them through decentralized exchanges, liquidity pools, or peer-to-peer mechanisms.
Key takeaways
- IMF First Deputy Managing Director Dan Katz warned that local-currency stablecoins could still funnel users into dollar stablecoins if both use the same blockchain rails.
- Katz said cross-stablecoin interoperability could shift foreign-exchange activity away from traditional intermediaries like banks and currency dealers.
- He suggested this dynamic could reduce friction in capital movement, affecting how authorities monitor and manage flows.
- Katz noted adoption outcomes may differ by country, with local tokens potentially replacing dollar holdings in highly dollarized economies.
- He urged regulators to enable compliant onramps, offramps, and onchain exchange points to manage risks.
How shared blockchain infrastructure could enable “digital dollar” access
Katz’s core point is about infrastructure. In his remarks—delivered in a speech at the University of Cape Town—he argued that if local-currency stablecoins and dollar-backed stablecoins are deployed on the same blockchain framework, the practical barriers to conversion could fall sharply.
That matters because, in decentralized finance environments, conversion does not require a single centralized issuer or intermediary to broker every transfer. Katz specifically referenced common DeFi routes: decentralized exchanges, liquidity pools, and peer-to-peer swaps. Under that model, users could move between token types directly, turning what begins as local-currency issuance into an easier path to dollar exposure.
Potential implications for FX monitoring and capital-flow tools
The IMF official linked interoperability to a broader policy concern: where foreign-exchange activity happens. Katz argued that moving FX-related activity away from banks and traditional currency dealers could reduce “friction” that authorities currently rely on to monitor and manage capital flows.
In other words, the issue is not only which stablecoin a user holds, but how quickly and through what channels they can reposition into a different currency exposure. If swaps become routine onchain, regulators may find it harder to observe the flow of currency demand through traditional institutional pathways.
At the same time, Katz framed the shift as potentially reinforcing the broader category of FX-focused stablecoins. He said that local-currency stablecoins “might even accelerate the adoption of FX stablecoins,” a statement that underscores the possibility that currency-linked token ecosystems could become more integrated over time rather than remaining siloed.
Adoption unevenness: South Africa as a case study
Katz pointed to South Africa to illustrate how adoption can diverge across token types. He said dollar-backed stablecoins have gained only limited traction there, while rand-linked tokens have attracted even less demand.
He cautioned that it is still too early to draw definitive lessons from any single country, but he offered an explanation for why users might still prefer dollar tokens. In his view, many participants may choose dollar stablecoins due to factors like liquidity, network effects, and cross-platform or cross-border acceptance.
Those characteristics can translate into more efficient trading and easier settlement—particularly in environments where the local currency faces volatility, lower market depth, or weaker confidence in local issuances. Even if a policy objective is to reduce dependence on the dollar, market structure and user preferences can pull activity back toward the most “usable” asset in practice.
Regulatory framing: country risk differences and compliant onchain rails
Katz said risks vary by country. He suggested that in highly dollarized economies, stablecoins may largely substitute for existing dollar holdings rather than creating incremental demand for dollars. But in countries where dollar access is restricted and the economic policy framework is weaker, stablecoins could instead increase foreign-currency demand.
This distinction is important for policymakers because it affects what “success” looks like. If stablecoins mainly repackage dollars already held domestically, the macro impact might differ from a scenario in which stablecoins provide a smoother mechanism to access additional dollar exposure.
To manage these trade-offs, Katz urged authorities to build regulatory frameworks around practical access points. Specifically, he called for authorities to bring onramps, offramps, and onchain exchange points within regulatory boundaries.
The policy takeaway is that banning activity is not the only route. Instead, the IMF official highlighted the need for rule-based access to onchain liquidity and conversion, so regulators can better understand flows and reduce the incentive for unregulated intermediaries.
Going forward, the key question for investors and builders is whether stablecoin issuers and blockchain platforms will prioritize interoperability across local- and dollar-denominated tokens—or isolate them through different infrastructure choices. Katz’s remarks imply that interoperability could materially change who ends up holding “digital dollars” and how quickly currency reshuffling occurs, so market participants should watch how regulators operationalize onramps, offramps, and onchain exchange controls in the jurisdictions most likely to experiment with local-currency stablecoin issuance.
