IMF Warns Local Stablecoins May Speed Digital Dollarization via On-Chain Swaps

Headline: IMF warns domestic stablecoins could inadvertently speed digital dollarization The International Monetary Fund has flagged a surprising risk: stablecoins issued in local currencies—meant to bolster domestic payments—could actually make it easier for people to switch into dollar-denominated digital assets, accelerating “digital dollarization.” What happened At a University of Cape Town speech on Aug. 7, IMF First Deputy Managing Director Dan Katz warned regulators to consider how stablecoins might reshape foreign-currency demand in emerging markets. His core point: when domestic and dollar stablecoins run on the same blockchain rails, on-chain tools like decentralized exchanges (DEXs), liquidity pools and peer-to-peer trades can let users swap into dollar tokens without going through banks or traditional FX dealers. That could weaken the role of local currency and sharpen demand for dollar-backed stablecoins. Market context - The stablecoin market has grown sharply since 2021 and has stabilized at roughly $300 billion over the past year. Nearly 99% of stablecoins are denominated in U.S. dollars, giving dollar-backed tokens deeper liquidity and broader acceptance. - That dominance means domestic-currency stablecoins face an uphill battle to gain the same reach and utility—even when regulators or private issuers try to promote them as local alternatives. Early evidence: South Africa Katz cited South Africa as an early example. Dollar stablecoins have gained limited traction there, and rand-denominated stablecoins even less so. Yet trading volumes of U.S. dollar stablecoins on South African platforms climbed from under 4 billion rand in 2022 to almost 80 billion rand in the first ten months of 2025—signaling rising domestic demand for dollar tokens. Katz urged caution, saying it’s too early to draw firm conclusions about long-term patterns. How the risk works When domestic and dollar stablecoins are interoperable on the same blockchain: - Users can swap between them directly on DEXs or via liquidity pools. - Peer-to-peer transfers and self-custody wallets reduce reliance on banks and traditional FX channels. - That on-chain route can sidestep capital controls and reporting mechanisms that banks and currency dealers typically enforce. Research backing the worry The Bank for International Settlements has reached similar conclusions. A BIS study of four dollar stablecoins and 27 fiat currencies found over 70% of cumulative net fiat inflows into those tokens originated from non-dollar currencies, and linked stablecoin demand to currency depreciation and on-chain/traditional FX pricing gaps. The BIS also found comparable inflows in countries irrespective of cross-border stablecoin restrictions—suggesting self-hosted wallets and borderless blockchain rails can blunt conventional controls. The BIS’s 2026 annual economic report echoes the concern that foreign-currency stablecoins can become accessible substitutes for domestic money in emerging markets, potentially making capital flows larger and more volatile. Not inevitable—context matters The IMF does not claim this outcome is automatic. Katz emphasized that effects vary by country: - In economies where residents already hold sizeable dollar balances, stablecoins may simply digitize existing holdings rather than increase total foreign-currency demand. - In countries with restricted dollar access or low confidence in the domestic currency, easier entry to digital dollars could amplify demand for foreign assets—especially during depreciation or inflation episodes. Policy recommendations The IMF is not calling for a blanket ban on foreign stablecoins. Instead Katz urged targeted policy responses based on each economy’s risks: - Bring onramps and offramps (exchanges, custodians, payment firms) under regulatory frameworks so authorities can apply KYC, monitoring and reporting. - Consider the implications of on-chain exchange points where domestic and dollar tokens can be freely swapped; existing FX and capital flow rules may need updating. - Strengthen cross-border cooperation, because activity can migrate to platforms outside a home jurisdiction. - Improve data collection—IMF work via the G20 Data Gaps Initiative aims to better track digital asset flows and help countries adapt rules. A pragmatic balance Katz also acknowledged the benefits: stablecoins can lower payment and remittance costs. IMF analysis cited by Katz suggests stablecoin transfers may cost less than the global average remittance fee (roughly 6.5%), though conversion fees and exchange rates can erode savings. Policymakers therefore face a trade-off: harness efficiency gains while managing the financial-stability and monetary-policy risks that easier access to dollar stablecoins could bring. Bottom line Domestic stablecoins are not an automatic defense against digital dollarization. If local tokens and dollar-backed tokens share blockchain infrastructure, they may create an on-chain bridge to dollars—forcing regulators to rethink FX rules, on/offramps and cross-border coordination rather than assume local stablecoins will protect monetary sovereignty.
