Latin America's stablecoin debate is evolving beyond issuer characteristics to focus on where dollar reserves should be held - offshore, in local banks, or across both systems. According to reports from CoinDesk, the region faces a unique challenge where regulators must address structural differences in controlling access to a currency they don't control. For savers in Buenos Aires, Bogota, or Mexico City, the specific stablecoin token (USDC, USDT, or others) barely matters as long as it maintains its peg and the custodian remains solvent.
The dollarization trend shows significant regional variations across Latin America. As reported by CoinDesk, Argentina remains the world's most dollarized crypto market by share of volume, but Brazil demonstrates the fastest growth with institutional stablecoin volume jumping from 5% of local crypto flows in 2024 to 84% in 2025. Mexico's Senate is currently debating legislation to regulate peso-pegged stablecoins, indicating widespread adoption across the region.
The concentration of dollar reserves in offshore accounts presents a domestic policy problem for regulators in regions where hard currency has been scarce for decades. According to CoinDesk analysis, a rising share of household and corporate dollars sitting in instruments reserved entirely offshore will eventually become a policy concern rather than a market outcome. This trend mirrors Kenya's recent proposal requiring stablecoin issuers to hold at least 30% of customer funds in domestically-domiciled banks.
Current Latin American regulatory frameworks have not addressed the reserve location question effectively. As reported by CoinDesk, Argentina's PSAV regime, Brazil's rules in force since February, and Mexico's Senate bill have not attempted to solve the reserve location issue. The analysis suggests that mandating local reserves would fragment liquidity currently concentrated in USDT and USDC, potentially pushing demand toward unregulated rails instead of compliant ones.
The preferred approach involves coexistence between locally-reserved and offshore-reserved dollar instruments operating under supervision, allowing users to decide where their dollars reside. According to CoinDesk analysis, this model would maintain convertibility that makes domestically-backed instruments useful for remittances while keeping dollars within supervised systems. The success of this approach will determine how much of Latin America's dollar savings remains inside regulated frameworks versus seeking unregulated alternatives.
