Insights

Banking and fintech strategy analyst

Macro Bank commits US$ 75M for 50% of Personal Pay operator, pending antitrust approval.

The agreement positions Banco Macro as a 50% shareholder in Micro Sistemas, the payment service provider behind “Personal Pay”. Banco Macro contributes capital and financial product capabilities, while Micro Sistemas contributes its active user base and payment use cases. The stated amount is a capital contribution in Pesos equivalent to US$ 75,000,000 for half of Micro Sistemas’ capital and voting rights.

This combination ties a traditional bank to a telecom-linked digital payments platform, potentially broadening distribution for Banco Macro’s products through “Personal Pay”. The impact will depend on how effectively the parties integrate financial offerings into existing transaction flows on the platform.

The transaction remains subject to approval by the relevant Antitrust Authority, so closing and implementation hinge on regulatory clearance. Subsequent disclosures after antitrust review and as the alliance is implemented may clarify the scale of customer adoption and financial contribution from this partnership.
