IRRBB: Revised SPM Module IR-1 and Completion Instructions
The Hong Kong Monetary Authority issues these completion instructions for Form MA(BS)12B, requiring selected authorized institutions to report monthly supplementary data on the weighted average interest costs of Hong Kong dollar-denominated interest rate-sensitive liabilities. The document specifies reporting scopes for locally and overseas incorporated institutions, detailing how to classify on-balance sheet liabilities, handle embedded options, and slot cash flows into time bands based on earliest repricing dates. It further provides precise definitions for deposits and non-interest-sensitive items, along with calculation methodologies for weighted average costs to support the compilation of the monthly composite interest rate for Hong Kong.
