The Isle of Man Financial Services Authority has issued a discussion paper, draft reporting form and guidance on implementing Basel III liquidity monitoring metrics for banks. The proposed return covers contractual maturity mismatch, funding concentration, available unencumbered assets, intraday liquidity and the Liquidity Coverage Ratio by significant currency. Reporting would be quarterly, based on March, June, September and December positions, with submissions due within one month. All five metrics would generally apply to Isle of Man-incorporated banks, while overseas banks’ Isle of Man branches would normally report only contractual maturity mismatch and funding concentration. Intraday liquidity positions for each month would be included in the quarterly return, and banks would need capacity to report more frequently if required. The Authority also proposes to retain the ability to require intraday liquidity reporting from a material overseas bank branch. Reporting is expected to begin for either the first or second quarter of 2027, when the new return would replace the existing maturity mismatch and large depositor return. Responses are due by Sept. 11, 2026, after which the Authority will review submissions and issue a feedback statement.

Isle of Man Financial Services Authority consults on Basel III liquidity monitoring metrics and quarterly bank reporting
The Isle of Man Financial Services Authority is consulting on quarterly Basel III liquidity monitoring metrics for banks, covering maturity mismatch, funding concentration, unencumbered assets, intraday liquidity and the Liquidity Coverage Ratio by significant currency. The full return would generally apply to locally incorporated banks, with narrower requirements for overseas bank branches. Reporting is expected to start in the first or second quarter of 2027 and replace the existing maturity mismatch and large depositor return.
