Overview

• Banks are activating MTU controls by Oct. 1 and are urging customers to set personal caps now, with major institutions publishing in‑app setup guides.
• Accounts left unconfigured will receive an automatic limit, commonly 1,500 Udis (about 12,500–12,800 pesos), with some outlets citing Sept. 30 as the cutoff to avoid defaults.
• Transfers that exceed a user’s cap will be blocked or require extra verification, and banks say they will call customers before executing out‑of‑limit movements.
• The measure covers electronic transfers such as SPEI, CoDi and Dimo for individuals, excluding in‑branch operations, physical card payments and Level 1 accounts.
• Users can set per‑operation limits and, at some banks, daily or monthly caps via mobile or online banking, while fintech apps like Nu and Mercado Pago report they are not yet covered.
