Overview
- The directive took effect on October 10, 2025, following publication in the Official Gazette, under Banxico Circular 08/2025.
- Financial institutions must classify incoming Family F 20‑peso notes as “in process of withdrawal/desmonetized” and deposit them with Banxico or its correspondents.
- The blue polymer note retains legal‑tender status under Article 4 of the Monetary Law, so the public can still use or deposit it during the phase‑out.
- Once received by banks, these notes will not reenter circulation and will be removed and destroyed as inventories are processed.
- Issued in 2007, the note exits after 18 years as Banxico prioritizes 20‑peso coins and newer Family G designs for durability and cost.
