Overdraft
A facility attached to a current account that allows the balance to fall below zero, up to a pre-agreed limit, with the bank charging interest or a fee on the amount borrowed.
What it means
An overdraft is a short-term credit arrangement built into a current account. When your account balance reaches zero and a payment is made, the bank covers the shortfall up to the agreed limit rather than rejecting the transaction. The overdrawn amount is effectively a loan, and the bank will charge for it - either through a daily or monthly fee, an interest rate applied to the negative balance, or both. The exact structure varies by institution and product.\n\nIn the GCC, overdraft facilities on personal current accounts are regulated at the national level. In the UAE, the Central Bank of the UAE sets conduct rules covering retail credit products, including overdrafts. In Saudi Arabia, SAMA oversees consumer lending standards. Qatar Central Bank (QCB), the Central Bank of Bahrain (CBB), the Central Bank of Kuwait (CBK), and the Central Bank of Oman (CBO) each carry equivalent supervisory roles in their jurisdictions. Conventional overdrafts accrue interest on the negative balance; Islamic banking alternatives use structures such as qard (an interest-free loan) or other Shariah-compliant arrangements approved by the bank's Shariah supervisory board.\n\nThere are two common types. An arranged overdraft - sometimes called an authorised overdraft - is agreed with the bank in advance, and the charges are disclosed upfront. An unarranged overdraft occurs when a payment takes the account beyond the agreed limit, or when no overdraft has been set up at all. Unarranged overdrafts typically carry higher charges than arranged ones, and some banks in the region will simply decline the transaction rather than permit an unarranged negative balance. Always check the fee schedule in your account's terms and conditions.
Why it matters for Gulf-based readers
For expats in the GCC, salary cycles matter. Many employers pay on a monthly cycle and the account can run low in the days before payday. An arranged overdraft can bridge that gap, but the cost of doing so varies significantly between banks - and between conventional and Islamic products at the same bank. Before using an overdraft, check the bank's published schedule of charges: look for a daily usage fee, an arrangement fee, and the rate applied to the outstanding balance. Do not assume a facility is in place; confirm it in writing with your bank.\n\nExpats should also be aware that in several GCC countries, being overdrawn without authorisation - or missing repayment on a credit facility - can have consequences beyond a fee. Unpaid bank debt can affect your ability to obtain a clearance certificate or exit visa in some jurisdictions. If you rely on international transfers to fund your account, factor in settlement times and FX conversion delays, as these can cause a temporary shortfall even when funds are nominally on their way.
