In the management of a company's bank accounts, a key governance issue is often raised: who should be designated as bank signatories? More specifically, should the Chief Financial Officer (CFO) serve as one of the joint signatories, or should they proactively exclude themselves from the signing list?

Bank signatories typically refer to individuals authorized to sign checks, approve transfers, or execute other banking transactions on behalf of the company. This authority directly relates to the security of funds and the effectiveness of internal controls. In practice, signing arrangements often fall into single signing, joint signing (requiring two or more people), and tiered signing (with different authority levels based on amounts).

Proponents of the CFO serving as a joint signatory argue that, as the highest-ranking officer in the finance function, the CFO bears ultimate responsibility for cash flow, and their involvement in signing helps ensure the compliance and strategic alignment of large payments. Additionally, the CFO's signature can enhance the confidence of banks and external auditors in the authenticity of transactions.

However, opponents emphasize the principle of Segregation of Duties. If the CFO is simultaneously responsible for financial records and bank signing, internal checks and balances may be weakened—for example, when the CFO leads the payment approval process, their signing authority may increase the risk of fraud. Therefore, many governance frameworks recommend that the CFO should avoid being the sole or primary signatory, and especially should not have unilateral signing authority in payment processes they oversee.

A compromise approach is: the CFO can serve as one of the joint signatories, but must sign together with another executive independent of the finance department (such as the CEO, COO, or a board member), with clear monetary thresholds established. For transactions exceeding the threshold, higher-level approval or board authorization would be required.

Furthermore, companies should regularly review the list of signatories to ensure it aligns with current management responsibilities and promptly remove signing authority from individuals who have left or whose duties have changed. Bank signing policies should also be consistent with the company's articles of association, authorization matrix, and audit recommendations.

Ultimately, there is no one-size-fits-all answer as to whether the CFO should be a signatory; it should be weighed based on the company's size, governance structure, risk appetite, and existing control environment. The core principle is that signing arrangements must serve the security of funds and clarity of accountability, rather than being based solely on job titles.
