4.3 Frequency for updating the data inputs

Institutions should update the historical data used to calibrate the data inputs from the current period, referred to in Article 325bc(3)(c) of Regulation (EU) No 575/2013, more frequently than monthly, as is provided in that Article, where updating those data monthly could lead to an inaccurate estimation of the market risk of the relevant positions.

Where institutions use Beta approximations or other random data-generating approaches for the purpose of determining the scenarios of future shocks, they should recalibrate the Beta coefficients or the parameters of the random data-generating approaches on at least a monthly basis.
