Definition
The loan-to-deposit ratio sets the loans a bank grants to its customers against the deposits of those same customers. It says how far deposits already fund lending.
It is taken at a date, on two balance-sheet lines. Here, at 30 June 2026.
The formula and how to read it
Loan-to-deposit ratio = customer loans ÷ customer deposits × 100.
Below 100%, deposits cover loans. The rest of the deposits is placed elsewhere: securities, cash, other banks. Above 100%, the bank lends more than its customers entrust to it. The difference comes from other resources: borrowings, special resources, equity, the interbank market.
The ratio is read, not ranked. A low ratio can come from a cautious bank or from a bank that lends little. A high ratio can come from a bank that lends a lot or from a bank that relies on other resources. The Funding section of the banks note reads it bank by bank.
Where to read it in Tunisian financial statements
Bank financial statements follow the Tunisian accounting standards NCT 21 to 25. Two balance-sheet lines are enough:
- AC3, «customer loans», on the assets side;
- PA3, «customer deposits», on the liabilities side.
Three reading traps
First trap: loans are net. Line AC3 is published after deducting provisions and reserved interest. For the same gross loans, a bank that provisions heavily therefore shows a lower ratio.
Second trap: not all loans are funded by deposits. AC3 also includes loans on special resources. Their funding sits on the liabilities side in another line, PA4, «borrowings and special resources». These loans weigh on the ratio while their funding does not appear in it.
Third trap: it is a snapshot. The ratio is taken at the closing date, here 30 June. It can move from one closing to the next: its trend matters as much as its level.
