Bank Mandate

A bank mandate is the instruction a business gives its bank on who can operate its accounts and how. It names authorised signatories, their limits and whether one or more must approve payments. Keeping it current protects against fraud and delays.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

A bank mandate is a company's instruction to its bank about who may operate an account and under what conditions, and it can name signatories, signing combinations, limits and powers to request services. The bank relies on its accepted version when processing instructions, so a company's internal approval chart may be stricter but does not automatically update the bank's records.

The mandate begins with legal identity, so check that the account holder, registration documents and people empowered to authorise a change all match. A director is not always entitled to act alone merely because of a job title, as the bank may require a board resolution, identity documents and its own form before recognising a new person or a revised signing rule.

Define separate permissions for viewing, preparing and approving transactions, since online banking often has administrator, maker and checker roles that do not map neatly to handwritten cheque signatories. State who can add beneficiaries, change user access and release payments, because a person who controls both user administration and final approval may bypass an otherwise sensible dual-control policy.

Signing limits should reflect how the business actually spends, for example one authorised person approving routine payments below a threshold and two above it. Check whether the limit applies per transaction, per day or to cumulative related payments, because if a purchase is split into several smaller transfers, a per-transaction threshold alone may not catch the total exposure.

A maker-checker process reduces the chance that one mistake or unauthorised instruction goes through unnoticed, though it does not eliminate collusion, account takeover or weak verification of a new beneficiary, so device credentials should be protected and payment details reviewed independently. Consider a monthly control report in which 196 of 200 payments above the policy threshold had two approvals, giving a dual-approval share of 98%.

That percentage is a prompt for investigation, not evidence that the four remaining payments were fraudulent, so find whether they were valid exceptions, processed through another channel or approved by a role that the report failed to capture. Keep the corporate policy and the bank mandate in sync, because if a board decides that the finance director can approve up to a new amount, the bank must accept the matching change before payments will pass.

Conversely, a bank mandate may still permit a former executive even after the internal policy removed them, so review both documents and retain written confirmation from the bank of when the change took effect. Staff departures are a critical trigger, so disable company system access, revoke online banking credentials and submit mandate changes promptly, and verify the completed change through the bank's official channel, since submitting a form is not the same as the bank accepting it.

If an urgent payment is due during the transition, plan a temporary authorised route instead of sharing credentials, and remember that changes in ownership, directors or company structure can also affect the mandate, so a new board resolution for the parent does not automatically change a subsidiary account. Map accounts to legal owners and maintain an inventory of mandate versions, limits and signatories.

UAE bank practices reflect both account terms and customer-due-diligence requirements, with Central Bank guidance considering authority for natural persons acting for customers and an individual bank possibly requiring its own supporting papers, so use the bank's current forms and ask it to confirm the authorised route for the particular account, because generic advice that a board resolution is always enough can be wrong. The best mandate is specific enough to stop a wrong payment without stopping legitimate work, and its value comes from keeping those permissions current and verifying that the bank has implemented each change, so treat it as a live financial control, not a form completed only when an account opens.

In practice

Real-world examples.

1

Example

Payments over $50,000 need two signatories. The bank mandate and the online banking settings both enforce the rule, so a single approver cannot release a large transfer. The finance team tests this once a year.

2

Example

A departing finance manager is removed from the mandate. HR notifies finance on the resignation date, and the bank form is submitted the same week. The finance director keeps the bank's written confirmation of the effective date.

3

Example

A board resolution adds a new director as signatory. The bank also asks for identity documents and its own form before it recognises the change. Until it confirms, the new director cannot approve payments.

Formula

Calculation

Dual approval share = Payments with two approvals / Total payments above threshold x 100 Worked example. 196 of 200 large payments had dual approval. - Share: 196 / 200 x 100 = 98% - Payments without dual approval: 200 - 196 = 4, which is 4 / 200 x 100 = 2% If those four payments averaged $60,000 each, the value needing review is 4 x $60,000 = $240,000, which shows why a 98% rate can still hide a material exposure.

Case study

Seen in the real world.

This illustrative and entirely fictional case follows Oasis Trading, an invented firm reviewing its accounts after a manager leaves. Its internal chart removed the manager, but the bank still lists them as a signatory. The firm temporarily tightens payment review, submits the bank's documents and confirms the effective change through an official bank channel. It also tests its alternate-approver route.

No loss or fraudulent payment is assumed. Oasis then builds a register of every account, its legal owner, the mandate version on file and the date the bank last confirmed it. Each leaver or new director now triggers a checklist item for the bank form, so the internal chart and the bank record are reviewed together rather than months apart.

Watch out

Common mistakes.

  • Removing a person internally but leaving the bank mandate unchanged.
  • Letting an administrator add users and approve large transfers alone.
  • Assuming the bank accepted a change because a form was submitted.

Questions

People also ask.

What is a bank mandate?

The bank's accepted instructions on who may operate an account and with what limits.

When should it be updated?

When roles, ownership or signing limits change, followed by confirmation that the bank accepted the update.

Why use dual approval?

It can reduce the chance of a single unauthorised or mistaken approval, though it does not eliminate fraud.
