Comparison of capital ratios with other publications

Capital ratios for the UK banking sector are published by the Bank of England (BoE) and the International Monetary Fund (IMF). Chart 4 shows a comparison of published capital ratios for the UK and the details of their differences are explained below. Table C provides descriptions of the underlying datasets and links to their definitions.

(a) Chart 4 is based on the most current publicly available metrics published by the institutions outlined in Table C at the time this statistical release was issued. ↩ ↩ ↩

The effects of the differences in datasets and methodologies can be generalised as follows:

Firm coverage – the BoE and the IMF publish capital ratios that represent averages of the total UK banking sector. While they all use the same data, the IMF publications are updated with a lag. This means that the latest quarterly figures are not available at the time of this publication and may include minor differences because this release’s chart is not using the latest vintage at this point of publication. The Financial Policy Committee’s (FPC) indicatorsfootnote [1] cover major UK banksfootnote [2] only, rather than the total UK banking sector, and this generally has a downward effect on the ratio.

Use of transitional or endpoint capitalfootnote [3] – the use of endpoint capital will tend to have a slight downward effect on ratios, compared to those using transitional capital.

Timing – both timeliness and frequency vary across datasets. The banking sector regulatory capital statistical release is the timeliest.
