Scores range from -100 (worst) to +100 (best). Source: Mashinii integrity intelligence platform.
Neither bank posts a positive score on the dimensions most frequently cited by ethical investors. The profiles differ: HSBC's lowest score is in arms financing and conflict, while Barclays' lowest is in animal welfare.
Money Laundering and Regulatory Fines
Both banks earn identical scores for different reasons.
HSBC's record centres on a $1.9 billion fine from the U.S. Department of Justice for facilitating money laundering transactions. The bank has since built compliance infrastructure, operating a global whistleblowing channel called "HSBC Confidential" that received 1,527 concerns in 2024 with a 35% substantiation rate. It maintains a zero-tolerance anti-bribery policy and requires mandatory financial crime training for all employees. A subsequent bribery self-report involving two former employees at a Chinese subsidiary in 2024 adds to the record.
Barclays has accumulated approximately $105 million in ethics-related regulatory fines over the past three years. The largest was a 40 million pound penalty from the FCA in 2024 for failing to disclose payments to Qatari entities in 2008. In 2025, two further fines totalling over 42 million pounds were levied for financial crime control failings related to WealthTek and Stunt & Co. Barclays has a comprehensive anti-bribery programme and a dedicated whistleblowing process, but these fines recur.
One bank faced a single $1.9 billion penalty. The other has faced a sequence of smaller fines spanning multiple years. Both score -20.

Fossil Fuel Financing: $200 Billion and Counting
Barclays scores lower despite having elevated climate risk to a principal risk category.
HSBC's total operational emissions (Scope 1, 2, and 3, categories 1, 2, 6) were 1.23 million tonnes of CO2 equivalent in 2024, a 5.5% year-on-year reduction. It sources 75.4% of its electricity from renewables and targets 100% by 2030. On the financing side, HSBC's net-zero target for financed emissions is 2050, its interim targets remain "under review," and its initial targets were not aligned with the Science Based Targets initiative.
Barclays conducted multiple climate scenario analyses in 2024, including internal stress tests and a nature exploratory stress test. But its disclosure on climate-related stranded asset risks consists of generic statements. Barclays is a founding funder of the Just Transition Finance Lab, but the documented evidence of actual emissions reductions is thinner than HSBC's.
For context, Lloyds and NatWest both score -20. NatWest has SBTi-validated targets and a formal zero-deforestation policy. Lloyds has sourced 100% renewable electricity since 2019 and offers green mortgage incentives. Both domestically focused banks outperform their larger, internationally exposed peers on this dimension.
HSBC's Nuclear Weapons Links vs Barclays' Defence Lending
This is the widest gap between the two banks.
HSBC's stated policy since 2000 has been to avoid financing weapons manufacturers. The evidence shows that policy has not translated into practice: there has been no significant downward trend in lending to the arms sector since the policy was introduced. Between January 2022 and August 2024, HSBC had approximately $3.5 billion in financial involvements with nuclear weapons industry companies. Public records show holdings in manufacturers of cluster munitions and depleted uranium. The bank also provided financial services to a Libyan engineer with ties to Muammar Gadhafi for alleged arms imports and maintained accounts for clients linked to arms trafficking in African countries.
Barclays scores -50. The bank provides 2 billion pounds in shares and 6.1 billion pounds in loans and underwriting to companies supplying weapons and military technology. This includes financial support to Elbit Systems, which is associated with cluster munitions production. The value of Barclays' shareholdings in these companies increased 55% since July 2022. However, Barclays is more transparent about its position: it openly states that it provides financial services to defence companies supplying NATO and its allies.
NatWest scores -70 on this dimension, with $2.2 billion in loans to nuclear weapons producers in 2024. Lloyds scores -50, with 2.7 billion pounds invested in nuclear weapons manufacturers between 2021 and 2023. Every major UK bank carries negative scores here.
Kind to Animals: HSBC -20, Barclays -70
The gap on animal welfare is the largest single-dimension difference in this comparison.
Barclays financed 55 of the world's largest livestock companies with $77 billion between 2015 and 2022. These companies engage in industrial-scale factory farming. Barclays makes no reference to animal welfare in any of its policies and has refused to adopt a basic animal welfare standard despite public pressure.
HSBC scores -20. The bank provided a six-figure loan to a dairy farm later exposed for animal welfare violations and launched a 1.2 billion pound fund for the agricultural sector including animal farming. It received a 0% rating for animal testing policy in a 2024 assessment and lacks any explicit animal welfare policies.
Both Lloyds (-60) and NatWest (0) tell different stories. Lloyds finances over 46,000 farming businesses but lacks a dedicated animal welfare policy. NatWest has no assessed evidence on this dimension.
Financial Inclusion: Neither Bank Provides the Data
Neither bank provided enough quantifiable data to score positively or negatively on fair pricing, financial inclusion, or customer empowerment. Both describe community lending programmes and financial literacy initiatives in their reports, but neither discloses the specific metrics the Mashinii methodology requires: percentages of customers from underserved segments, average APRs relative to market medians, share of loan books dedicated to inclusion lending, or data portability features.
This reflects a disclosure gap rather than necessarily a performance gap. It is common among large banks.
Worker Pay and Gender Equality at UK Banks
HSBC outperforms Barclays in several areas. It scores +20 on Respect for Cultures & Communities, reflecting over 50 formal partnerships with local community groups through its Climate Solutions Partnership and application of the Equator Principles. It earns +10 on Fair Pay & Worker Respect, with certification as a global Living Wage employer by the Fair Wage Network in 2024, though a UK median gender pay gap of 46.7% is part of the same record. It scores +10 on Fair Trade & Ethical Sourcing, with 96.7% of its roughly 10,400 contracted suppliers confirmed as adhering to its Supplier Code of Conduct.
Barclays' positive dimension is Safe & Smart Tech at +10, driven by FIPS140-2 Level 2 certified encryption, comprehensive vulnerability management with critical vulnerabilities targeted for remediation within 15 days, and Board oversight of AI risks. HSBC scores -10 on the same dimension, where a 63.9 million pound FCA fine for anti-money laundering monitoring deficiencies and a Bank of England order to review its data handling practices weigh on the score.

- Your bank financed 55 of the world's largest livestock companies with $77 billion over seven years
- Your bank has accumulated approximately $105 million in regulatory fines in three years, with new penalties arriving annually
- Your bank scores +10 on technology security -- the best of any UK bank analysed -- with FIPS140-2 Level 2 encryption and 15-day critical vulnerability remediation
- Your bank provides 2 billion pounds in shares and 6.1 billion pounds in loans to weapons manufacturers, openly stating it serves NATO-allied defence companies
HSBC vs Barclays: The Bottom Line
Neither bank offers a clean record. Both carry negative scores across multiple dimensions. The composition of those risks differs.
HSBC's risks concentrate in: arms financing (-80), climate (-40), and a single historic $1.9 billion money laundering penalty.
Barclays' risks concentrate in: animal welfare (-70), climate (-50), recurring regulatory fines, and factory farming finance.
The domestic alternatives are not clean either. Lloyds carries a -40 on integrity and -60 on animal welfare. NatWest scores -70 on arms. But both outperform on environment and waste.
UK banking as a sector scores poorly across ethical dimensions. For values-aligned investors, the question is not which bank is ethical -- none of them are -- but which specific risks you are willing to hold, and which you are not.
