Basel Framework MAR32.9, Table 1, version in force from 1 January 2023. These are rule parameters, not estimates, so no significance statistic applies.

The revised trading book framework replaced value at risk with a 97.5 per cent expected shortfall across five liquidity horizons, and ties a bank's capital multiplier to how often its model failed. The whole ladder runs from 1.50 to 2.00.
