255.Sections 98 to 102 make provision concerning the relationship between the Payment Systems Regulator and other regulators. Under section 98 the Payment Systems Regulator, the Bank of England, the FCA and the PRA are required to co-ordinate the exercise of their relevant functions (as defined by subsection (5) of section 98). The duty to co-ordinate only applies to the extent that compliance is compatible with the advancement by each regulator of any of its objectives and does not impose a burden on the regulators that is disproportionate to the benefits of compliance. Under section 99, the Payment Systems Regulator, the Bank of England, the FCA and the PRA are obliged to draw up a memorandum of understanding which describes their respective roles and how they intend to comply with the duty to co-ordinate the exercise of their functions. The Bank, the FCA and the PRA each have a power (set out in sections 100, 101 and 102 respectively), where certain conditions are satisfied, to give the Payment Systems Regulator a direction not to exercise a power or not to exercise it in a specified manner.
