Published on 19 December 2025

The key points for 2025 Q3:

The Common Equity Tier 1 (CET1) capital ratio for the UK banking sector has decreased by 0.2 percentage points to 15.2% in 2025 Q3.
The level of CET1 capital increased by 0.4% on the quarter, from £458 billion to £460 billion.
The level of total risk-weighted assets increased by 2.0% from £2,967 billion to £3,025 billion this quarter.

(a) Figures throughout this document may not correspond exactly due to rounding.

Lines represent the total capital ratio, Tier 1 and CET 1 ratio of the UK banking sector over the past 18 quarters. All three ratios have decreased in 2025 Q3.

Bars represent contributions made by the quarterly percentage changes in the levels of risk-weighted assets (RWAs), tier 1 and tier 2 capital on the quarterly percentage change in total capital ratio over the past six quarters. The impact of the increase in capital was offset by the larger increase in total RWAs, which resulted in an overall decrease to the total capital ratio in 2025 Q3.

(a) The categories of risk-weighted assets used are as defined in the reporting templates in the annexes to the Implementing Technical Standards (ITS) on Supervisory Reporting (Regulation (EU) No 573/2013).

Bars represent the breakdown of quarterly changes in the levels of risk-weighted assets (RWAs) by type over the past six quarters. There has been an increase across all published risk types within RWAs. This resulted in an overall increase of total RWAs in 2025 Q3.

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.

Chart shows capital ratios for the UK banking sector published by different institutions. These ratios are similar but not identical due to differences in firm coverage and data revisions.

(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) indicators^{footnote [1]} cover major UK banks^{footnote [2]} only, rather than the total UK banking sector, and this generally has a downward effect on the ratio.
Use of transitional or endpoint capital^{footnote [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.

Publishing institution	Dataset	Firm coverage	Transitional or endpoint capital	Averaging method
Bank of England	Banking sector regulatory capital	Total UK banking sector	Transitional	Weighted mean
International Monetary Fund	Financial soundness indicators	Total UK banking sector	Transitional	Weighted mean
Bank of England	FPC indicators	Major UK Banks	End-point^(a)	Weighted mean

(a) From 2018, Basel III CET 1 and Tier 1 capital ratios reflect IFRS 9 transitional arrangements.

In July 2023 the FPC added the CET1 ratio as one of its Core indicators, alongside the Tier 1 ratio.
The group currently includes Barclays, HSBC, Lloyds Banking Group, Nationwide, NatWest, Santander UK, and Standard Chartered. Note: Virgin Money were included for the periods from 2020 Q4 to 2024 Q3.
