Oobit’s new report makes a simple claim with big downstream risk. In almost all Latin American markets it reviewed, most stablecoin transactions were completed using USDT.
That matters because USDT is not just another token in those flows. Oobit frames it as a “de facto dollar proxy” for the region. When most settlement uses one asset, you get concentration, and concentration turns small frictions into system-wide headaches.
USDT as the default “cash” layer
Oobit also characterizes the region’s stablecoin use as akin to cash. The reader takeaway is straightforward. In these markets, stablecoins are not just on-chain experiments. They operate like day-to-day payment infrastructure.
When “cash-like” activity leans on one stablecoin, the operational dependency stack also leans on one issuer and one compliance perimeter. If anything interrupts USDT availability, liquidity, or transfer rails, the pain lands quickly.
What Oobit says USDT replaces
The Oobit report positions USDT as the go-to settlement vehicle where local preferences and currency volatility make stable value attractive. In practice, that means merchants, counterparties, and intermediaries are likely routing value through USDT because it already matches the expected unit of account.
Oobit’s phrasing is the key here. Calling USDT the “de facto dollar proxy” implies users treat it like a functional substitute for USD exposure. In a cash-like model, the asset that looks most like dollars wins the flows.
The risk of “one proxy” stablecoin plumbing
Concentration risk is the obvious pressure point. If nearly all stablecoin activity in a market centers on USDT, then stablecoin settlement becomes a single line in the spreadsheet. An issuer-specific issue, a transfer bottleneck, or a market-structure shock can ripple through payments even if everything else on-chain still works.
There’s also a liquidity mechanics angle. Stablecoin payments need quick conversions and tight spreads. When one token captures usage share, liquidity tends to cluster around it. That can look efficient during calm periods and fragile during stress, because alternatives may not have comparable depth.
Oobit’s report does not spell out these failure modes. But the dominance it describes creates the conditions where they matter.
What to watch next
Oobit’s finding is directional: USDT is the default stablecoin for LATAM stablecoin transactions in “almost all” markets surveyed, according to the report summary. Next questions follow.
Which LATAM markets are the exceptions. How much the pattern shifts during periods of heightened volatility. Whether market participants route around USDT when rails get noisy.
Until those details show up, the useful conclusion is not hype. It is dependency mapping. Oobit’s report suggests the “stablecoin layer” in LATAM is less a multi-asset ecosystem and more a USDT-led payment rail.
