Latin America's largest crypto platform brings peso-denominated lending to DeFi through its MXNB stablecoin
For all the talk about crypto eating traditional finance, most of DeFi still runs on dollars. Stablecoins pegged to the US dollar dominate lending markets, liquidity pools, and payment rails.
That just changed. Bitso, the largest digital asset platform in Latin America, has launched the first onchain money market denominated in Mexican pesos, built on Morpho’s open credit protocol. The new credit markets and vaults use MXNB, Bitso’s fiat-backed peso stablecoin, to enable peso-denominated lending and borrowing without ever touching a traditional bank.
What Bitso and Morpho actually built
Morpho operates as an open credit network, essentially infrastructure that lets anyone create lending markets with customizable risk parameters. Bitso plugged MXNB into that framework. Technical documentation references a cross-currency market pairing MXNB with USDC, featuring an 86% loan-to-liquidation-value (LLTV) ratio with oracle integration.
MXNB itself is a fiat-backed stablecoin pegged 1:1 to the Mexican peso. Bitso initially launched it on Arbitrum before expanding to Base, both Ethereum Layer 2 networks. The stablecoin is also being integrated into Ripple’s XRPL Permissioned DEX to facilitate US-Mexico settlement flows.
Morpho has accumulated over $11 billion in deposits and already supports institutional heavyweights like Coinbase and Galaxy with its onchain lending infrastructure.
Why the Mexican peso matters for DeFi
Peso-denominated lending markets eliminate currency mismatch entirely. A Mexican business can deposit MXNB, earn yield in pesos, and borrow against it without ever converting to dollars.
The Morpho Association secured $175 million in funding on June 9, 2026, with participation from Apollo Funds and Circle Ventures.
What this means for investors
For Morpho specifically, the expansion into non-dollar markets diversifies its protocol beyond the crowded USDC/ETH lending space. The $11 billion already sitting in Morpho deposits provides a substantial base, but peso markets tap into an entirely new user demographic.
The integration of MXNB with Ripple’s XRPL for cross-border settlement adds another dimension. If Mexican businesses can move pesos onchain, lend them on Morpho, and settle cross-border payments through XRPL, you start to see the outline of a parallel financial system that doesn’t require correspondent banking relationships.
Investors should watch MXNB’s total supply growth and Morpho vault deposits as the earliest indicators of whether this experiment gains real traction.
