The PRA has finalised the date of changes to liquidity reporting rules. On 22 April 2016, FSA 050-053 will be switched off and the EU requirements to report additional liquidity monitoring metrics introduced. Firms will not be required to report both sets of returns simultaneously. Note the first reporting date for returns C67.00, C68.00, C69.00, C70.00 and C71.00 will be 30 April for monthly reporters, and 30 June for quarterly reporters.
C66.00 (Maturity analysis) has been dropped
For the months from April 2016 to October 2016 only, the reporting remittance date for monthly reporters is the 30th calendar day after the reporting reference date. Afterwards it reverts to 15 calendar days. Quarterly reporters have 30 calendar days to remit returns.
Reporting remains monthly – but quarterly for institutions that are not part of a group with subsidiaries or parent institutions located outside the UK and the “balance sheet total of the institution represents only a small proportion of the sum of individual balance sheet totals of all institutions in the respective Member State and the institution has total assets which are not significant”. This means almost all UK banks and building societies are quarterly.
