## What is HSBC's technology stack?

HSBC runs about 9,000 applications, most of them on cloud, and is retiring a third of the estate. On the annual results call in February 2026 chief executive Georges Elhedery said 'I think we are quite mature on Cloud', that about 3,000 applications are flagged as non-strategic for demise by 2028 and that more than 1,100 were demised in 2025. The bank uses more than one cloud: its June 2026 release counts more than 600 HSBC applications already running on Google Cloud, and AWS said in November 2025 that the PayMe wallet had moved its entire platform to AWS. On the AI layer, the chief technology officer is building a central AI platform that gives colleagues access to a range of models, with Mistral AI models self-hosted on HSBC's internal systems and Gemini models through Google Cloud, while Microsoft said in July 2026 that HSBC had committed to 200,000 Copilot seats. Elhedery said 31,000 engineers have coding assistants and that technology is about 20% of costs. HSBC has not published its split between cloud providers or the core banking systems it runs by market.

## Who runs technology at HSBC and how much does it spend?

Stuart Riley joined HSBC as Group Chief Information Officer in February 2024 and leads the bank's technology strategy; he was previously Co-Chief Information Officer of Citi. In March 2026, when HSBC named its first chief AI officer, it also widened the remit of chief technology officer Mario Shamtani to 'modernising core platforms, building a central AI platform colleagues can use to access a range of models, and leading key strategic partnerships'. ([HSBC Holdings plc](https://hsbc.com/-/files/hsbc/who-we-are/leadership/biography/260904-biography-stuart-riley.pdf), [HSBC Holdings plc](https://hsbc.com/-/files/hsbc/media/media-release/2026/260323-david-rice-announced-as-chief-ai-officer.pdf))

On cost, Elhedery told analysts in February 2026 that 'you could broadly assume that 20% is the cost that we're spending on technology'. He said retiring legacy and non-strategic applications, which consume maintenance costs, patching costs and licence fees, frees capacity to invest, and that the biggest investment in new technology 'is definitely going into Generative AI'. ([HSBC Holdings plc](https://www.hsbc.com/-/files/hsbc/investors/hsbc-results/2025/annual/pdfs/hsbc-holdings-plc/260226-annual-results-to-investors-and-analysts-transcript.pdf))

On people, eFinancialCareers reported on February 25, 2026 that HSBC said it had 'invested' in 1,800 technology full-time employees over the previous year, while cutting other roles. ([eFinancialCareers](https://efinancialcareers.com/news/hsbc-has-both-empowered-its-people-with-ai-and-hired-1-800-technologists))

What is not on the record: HSBC has not published how its applications divide between cloud providers and its own data centers, which core banking systems it runs in each market, or a total technology headcount.

## Common questions

### Which cloud providers does HSBC use?

At least two are named in primary sources. HSBC's June 2026 release says more than 600 of its applications already run on Google Cloud, and AWS announced in November 2025 that PayMe, HSBC's Hong Kong wallet, had migrated its entire platform to AWS. HSBC has not published the split between providers.

### How many applications does HSBC run?

About 9,000, chief executive Georges Elhedery said on the annual results call in February 2026. About 3,000 of them are flagged as non-strategic and due to be demised by 2028, and more than 1,100 were demised in 2025, which he said frees investment capacity for new technology.

### Which AI models does HSBC use?

Several. HSBC's December 2025 release says Mistral AI models are self-hosted on the bank's internal technology systems, the June 2026 Google Cloud partnership adds Gemini models and the Gemini Enterprise Agent Platform, and the chief technology officer is building a central AI platform so colleagues can access a range of models.

### How much does HSBC spend on technology?

HSBC does not publish a single technology budget. Asked in February 2026, Elhedery said analysts could broadly assume that 20% of costs go on technology, and that generative AI is where the biggest investment in new technology is going. He gave no figure for AI alone.

### Who is HSBC's chief information officer?

Stuart Riley, who joined as Group Chief Information Officer in February 2024 after serving as Co-Chief Information Officer of Citi. Mario Shamtani is chief technology officer, with a remit widened in March 2026 to modernising core platforms and building the central AI platform.
