Holdings plc and ‘HSBC’, the 'Group' and the ‘HSBC Group’ refer to 
HSBC Holdings together with its subsidiaries; similarly, ‘HSBC Bank’ 
and the ‘bank’ mean HSBC Bank plc, and the ‘group’, ‘we’, ‘us’ and 
‘our’ refer to HSBC Bank together with its subsidiaries.
When used in the terms ‘shareholders’ equity’ and ‘total 
shareholders’ equity’, ‘shareholders’ means holders of HSBC Bank 
ordinary shares and those preference shares and capital securities 
issued by HSBC Bank classified as equity. The abbreviations ‘£m’ and 
‘£bn’ represent millions and billions (thousands of millions) of pounds 
sterling, respectively.

Disclosures and Governance
 
Regulatory framework for disclosure
Our Pillar 3 Disclosures at 30 September 2025 comprise both 
quantitative and qualitative information required under Pillar 3. These 
disclosures are made in accordance with the Prudential Regulation 
Authority (‘PRA’) Rulebook Disclosure (Capital Requirements 
Regulation). They are supplemented by specific additional 
requirements of the PRA and discretionary disclosures on our part.
We are supervised on an individual basis in the United Kingdom ('UK') 
by the PRA, which receives information on the capital and liquidity 
adequacy of, and sets capital and liquidity requirements for, the bank 
as a whole. Individual banking subsidiaries are directly regulated by 
their local banking supervisors, who set and monitor their local capital 
and liquidity adequacy requirements. In most jurisdictions, non-
banking financial subsidiaries are also subject to the supervision and 
capital and liquidity requirements of local regulatory authorities.
The Basel Committee on Banking Supervision (‘Basel’) III framework 
is structured around three ‘pillars’, with the Pillar 1 minimum capital 
requirements and the Pillar 2 supervisory review process 
complemented by the Pillar 3 market discipline. The aim of Pillar 3 is 
to produce disclosures that allow market participants to assess the 
scope of application by banks of the Basel framework and the rules in 
their jurisdiction, their capital resources, risk exposures and risk 
management processes, and hence their capital adequacy.
We calculate the bank's capital for prudential regulatory purposes 
using the Basel III framework, as implemented in the UK. Any 
references to European Union (‘EU’) regulations and directives 
(including technical standards) should, as applicable, be read as 
references to the UK’s version of such regulation and/or directive, as 
onshored into UK law under the European Union (Withdrawal) Act 
2018, and may be subsequently amended under UK law. We refer to 
the regulatory requirements of the Capital Requirements Regulation 
and Directive, the CRR II regulation and the PRA Rulebook as ‘CRR II’.
Regulatory reporting processes and 
controls
We have advanced our comprehensive initiative aimed at 
strengthening our global regulatory reporting processes and making 
them more sustainable, including enhancements to data, consistency 
and controls. While this programme continues, there may be further 
impacts on some of our regulatory ratios as we implement 
recommended changes and continue to enhance our controls across 
the process.
Business Segments
On 22 October 2024, HSBC Holdings plc announced that the HSBC 
Group would simplify its organisational structure to help accelerate 
delivery against its strategic priorities. Effective 1 January 2025, the 
HSBC Group started to operate through four new businesses – Hong 
Kong, UK, Corporate and Institutional Banking ('CIB'), International 
Wealth and Premier Banking ('IWPB'). HSBC Bank plc realigned its 
organisational structure effective 1 January 2025 accordingly, which 
includes CIB and IWPB businesses in Europe.
Comparatives and references
To give insight into movements during 2025, we provide comparative 
figures, commentary on variances and flow tables for capital 
requirements. In all tables where the term 'capital requirements' is 
used, this represents the minimum total capital charge set at 8% of 
risk-weighted assets ('RWAs') by Article 92(1) of CRR II. Narratives 
are included to explain quantitative disclosures where necessary.
Where disclosures have been enhanced, or are new, we do not 
generally restate or provide comparatives. Wherever specific rows 
and columns in the tables prescribed are not applicable or are 
immaterial to our activities, we omit them and follow the same 
approach for comparatives.
In alignment with the PRA Rulebook table requirements, we have 
shaded cells where no information is required to be disclosed. 
Pillar 3 requirements may be met by inclusion in other disclosure 
media. Where we adopt this approach, references are provided to the 
relevant pages of other documents.
The table below references where disclosures have been enhanced.

Frequency and location
We publish our Pillar 3 Disclosures quarterly on our website

Material risks
Pillar 3 requires all material risks to be disclosed to provide a 
comprehensive view of a bank’s risk profile.
Governance
Our Pillar 3 Disclosures are governed by the bank’s regulatory 
reporting policy and associated internal controls framework. This 
document has been approved by the HSBC Bank plc Chief Financial 
Officer following recommendation by the HSBC Bank plc Disclosure 
Committee. In this context, the HSBC Bank plc Disclosure Committee 
acts under delegated authority from the HSBC Bank plc Audit 
Committee.

Key metrics
The table below sets out the key regulatory metrics covering HSBC Bank plc's available capital (including buffer requirements and ratios), RWAs, 
leverage ratio, Liquidity coverage ratio (‘LCR’) and Net stable funding ratio (‘NSFR’). Effective 1 January 2025, the IFRS 9 transitional 
arrangements came to an end, followed by the end of the CRR II grandfathering provisions on 28 June 2025. Accordingly, our capital figures are 
the same on both the transitional and end-point basis. The leverage ratio is calculated using the CRR II end-point basis for capital. LCR is 
reported as the average of the preceding 12 months while NSFR is reported as the average of the preceding four quarter-end values.

1 From 30 June 2025, the regulatory valuation of Tier 2 capital includes the accrued interest. Prior periods have not been restated.
At 30 September 2025, our common equity tier 1 ('CET1') capital ratio 
decreased to 18.9% from 19.4% at 30 June 2025. The key drivers 
impacting the CET1 ratio were:
–
a (0.7) percentage point decrease from capital reduction, mainly 
through regulatory losses and dividends;
–
a (0.2) percentage point decrease in foreign exchange movement, 
fair value through other comprehensive income and other capital 
movements; and
–
a 0.4 percentage point increase from lower RWAs, mainly due to a 
balance sheet reduction in corporate lending. 
Throughout 3Q25, we complied with the PRA's regulatory capital 
adequacy requirements, including those relating to stress testing.

Risk-weighted assets
The table below shows total RWAs including free deliveries, and the corresponding total own funds requirement split by risk type. Equities 
under the simple risk-weighted approach include off-balance sheet collective investment undertakings ('CIU') equity exposures, calculated as 
per the PRA Rulebook Article 132(c) and 'Other counterparty credit risk' includes securities financing transactions RWAs.

1 These balances are included in rows 2 and 5 of the table and include thresholds for the recognition of significant investments and deferred tax assets.
The 3Q25 quarter RWA movements in the table above are explained by risk type in the following comments.
Credit risk, including amounts below 
the thresholds for deduction
Credit risk RWAs decreased by £(2.3)bn, primarily due to a £(2.6)bn 
balance sheet reduction in corporate lending and a £(0.7)bn fall due to 
methodology changes, mainly within the CIB business. This was 
partly offset by a £1.0bn increase in foreign currency translation 
differences.
Counterparty credit risk, including 
settlement risk
Counterparty credit risk RWAs increased by £1.7bn, primarily in the 
CIB business, driven by a £1.1bn rise from methodology changes, a 
£0.3bn increase in foreign currency translation differences and a 
£0.3bn increase due to other movements in the derivative and repo 
portfolio.
Securitisation
Securitisation RWAs increased by £0.2bn, mainly due to new 
positions in the CIB business. 
Market risk
Market risk RWAs decreased by £(0.2)bn, mainly due to reduction in 
value at risk ('VaR') and foreign exchange exposures in our CIB 
business and Corporate Centre. This was partially offset by an 
increase in foreign currency translation differences.
Operational risk
Operational risk RWAs increased by £0.2bn, mainly due to foreign 
exchange translation differences in our CIB business.
