Société Tunisienne de Banque (STB) showed mixed performance indicators, marked by a sustained increase in deposits and net banking income, as of the end of September 2025, despite a notable decline in customer loans and borrowed funds.
Customer deposits increased by 842.6 million dinars, a rise of 7.5% year-on-year, reaching 11,970 million dinars at the end of September 2025.
This positive trend stems mainly from the strong performance of savings deposits, which rose by 7.3% to 4,869 million dinars, representing 40.6% of all deposits.
Term deposits also showed a strong increase of 21.28%, standing at 2,583 million dinars.

Borrowed funds contracted by 19.6%, falling to 517.7 million dinars compared to 644.1 million a year earlier. This decrease is due to a reduction in bond and private borrowings (-28%) and special resources (-11%).
Similarly, net customer loans declined by 11.3%, falling from 9,970 million dinars to 8,845 million dinars as of September 30, 2025.

Conversely, the investment portfolio experienced a strong increase of 54.8%, reaching 4,404 million dinars, reflecting a greater orientation towards long-term investments.
Net banking income (NBI) increased by 6.6%, reaching 522.7 million dinars. This change results from a 3.15% rise in banking operating income to 1,089 million dinars, while banking operating expenses remained almost stable (+0.14% to 566.2 million dinars).
Operating expenses increased slightly by 2.76% to 251.8 million dinars, but the operating ratio improved, moving from 49.99% to 48.17%, indicating better cost control.
