Deposit stability is one of the fundamental pillars of the banking system. However, recent events have shown that while the underlying drivers of deposit withdrawals remain the same, their speed and scale have changed dramatically. Digitalization, social media, and instant access to information have transformed depositor behavior and significantly reduced the time banks have to respond.

This document provides an in-depth analysis of the mechanisms that explain the stability, and fragility, of non-maturity deposits, combining classical economic theory with the new challenges of the digital environment. It explores key aspects such as the role of deposit insurance, depositor concentration, competition from non-bank financial institutions, the impact of rising interest rates, and the growing influence of social media on banking confidence.

It also examines the structural shifts that have increased system volatility, including the rise of uninsured deposits, the expansion of money market funds, and the ability of depositors to move large volumes of capital within hours. These dynamics have contributed to recent banking stress events unfolding at unprecedented speed, challenging traditional liquidity management and regulatory frameworks.

The presentation also offers a strategic perspective on how regulatory approaches are evolving and what this new reality means for banks, supervisors, and risk managers.

If you want to understand why deposit stability has become more complex than ever—and what it means for the future of the financial system—we invite you to explore the full document.
