The Great Bank Customer Battle: CASA
Summary
The core idea of the story, in a faster reading layer.
The race to become a customer's primary bank has shifted, as CASA (Current Account and Savings Account) is no longer simply a measure of non-time deposit accounts but rather an indicator of a customer's ability to retain actual transaction balances. Rising funding costs, declining CASA, and pressure on net interest margins have forced banks to move beyond relying on loan growth to sustain profits.

CASA is making a comeback as a key strategic focus area for the banking industry in 2026, but the nature of this competition has changed. As funding costs tend to rise, CASA declines and net interest margin (NIM) faces pressure to narrow, banks cannot solely rely on loan growth to maintain profitability. As a result, CASA is no longer simply a measure of non-time deposit accounts, but a gauge of a bank's ability to retain its customers' actual transactional cash flow.
