Financial Regulation

A Practitioner’s Guide to Finding the Constraint That Actually Binds

These are the four Excel workbooks that go with the book. Every figure the book prints is reproduced in them by a live formula rather than a typed constant — move a risk weight, a loan-to-value band, a national buffer rate or the share of secured funding raised against the bank’s own inventory, and every dependent number moves with it. Each one ends with a Checks sheet setting the printed figure beside the computed one: 178 controls in all, every one green. If a control ever reads FAIL, the workbook is wrong, not the book.

The four workbooks

How they are built

There is one Inputs sheet in each file, and it carries the only entered values: the balance sheet, the funding, the risk weights, the loan-to-value bands, the national buffer rates, the requirements. Everything else is computed from them. Where the texts permit two readings, both are shown and neither is chosen — that is the subject of chapter 17.

The workbooks were checked by moving the inputs and confirming that every dependent figure moved with them. Shifting eight points of the mortgage book from the lowest loan-to-value band to the highest moves the portfolio weight, the standardised total, the floor trajectory and the funding factor together. Raising the internal weight on corporate lending moves the binding year of the output floor from 2029 to 2030 through the lookup.
