Pix Launches MED 2.0 to Expand Fraud Refunds Beyond the First Account

Overview

• The Banco Central made MED 2.0 available to institutions on November 23, 2025, with mandatory adoption set for February 2, 2026.
• The upgraded mechanism traces funds through multiple accounts by mapping transaction trees and sharing paths across institutions.
• Victims who contest a fraudulent Pix transfer can have funds returned within up to 11 days under the new process.
• A contestation button introduced on October 1 lets users file disputes directly in their banking apps, speeding blocks and recovery.
• The central bank allows preventive blocks of up to 72 hours when fraud is suspected, and officials expect many institutions to adopt MED 2.0 before the deadline.
