Anchorage Digital Expands Bitso Partnership to Power US-Mexico Remittance Corridor

Anchorage Digital Bank has widened its collaboration with Latin American digital financial services group Bitso to serve as the primary institutional custody layer across both legs of the cross-border US-Mexico payment channel ¹. Under the agreement announced on Oct. 27, 2026, Anchorage Digital Bank, N.A. will provide custody for $MXNB, a Mexican peso stablecoin, across six public blockchains: Arbitrum, Base, Ethereum, Polygon, Avalanche, and Arc ¹.

Concurrently, Bitso listed $USDPT, Western Union's dollar stablecoin, alongside Tether's $USAT token ¹. Anchorage Digital Bank issues and custodies both US dollar tokens ¹. Retail Bitso users located in Mexico can trade USDPT against Mexican pesos directly within the Bitso application, while Western Union agents operating Bitso Business accounts can convert USDPT across supported fiat balances ¹. The expansion builds on earlier institutional infrastructure initiatives by Anchorage, including previous integrations such as the CustodySync platform built alongside Chainlink ¹.

Modernizing Cross-Border Settlements

The US-Mexico remittance channel represents one of the largest cross-border money flows worldwide, moving tens of billions of dollars each year ¹. Bitso currently processes approximately 15% of this total volume through its rails, whereas traditional transactions historically rely on correspondent banks, wire services, and retail cash-pickup chains that exhibit higher costs and delayed settlement times ¹.

By integrating regulated custody for both dollar- and peso-denominated tokens under a federally chartered institution, the two firms plan to shift settlement to around-the-clock onchain rails ¹. Anchorage Digital Chief Executive Officer Nathan McCauley stated that securing MXNB across multiple chains alongside USDPT and USAT on Bitso positions the bank directly where institutional volume originates ¹. Bitso Head of Stablecoins Ben Reid noted that having federally backed custody beneath dollar- and peso-denominated stablecoins provides the compliance structure institutional participants require for large-scale transfers ¹.
