The Evolution of AI in Financial Services
The integration of generative artificial intelligence into financial services has entered a new phase, marked by practical implementation rather than speculation. This shift comes three years after the technology entered mainstream consciousness in late 2021, with organisations now focusing on commercial viability rather than technical possibilities.
In Mastercard‘s latest signals report, Microsoft Founder Bill Gates characterises the technology as ‘the most important advance since the graphical user interface,’ though OpenAI CEO Sam Altman admits he is ‘a little bit scared’ of the technology his company has developed.
Key Developments in Generative AI
The financial sector’s approach to generative AI implementation centres on three key developments: informed AI, perceptive AI, and proactive AI. Informed AI combines large language models with external data sources, while perceptive AI interprets environmental data. Proactive AI operates with reduced human oversight.
Informed Deployment Methods
Banks and payment providers employ methods such as fine-tuning and retrieval-augmented generation (RAG). Fine-tuning involves training an AI model on specific data sets, while RAG allows AI systems to access external databases in real-time. Currently, 20% of enterprises use fine-tuning, while 80% employ RAG to supplement their language models.
In the banking sector, 73% of mortgage lenders view generative AI as central to improving operational efficiency in lending processes. The technology enables underwriters to incorporate market conditions and property trends into their analyses. Financial institutions also use AI for fraud monitoring, transaction analysis, and personalised financial advice.
Operational Challenges
The implementation of AI in financial services faces technical and regulatory hurdles. Banks must ensure AI systems operate on a zero-retention basis to protect sensitive information while navigating global regulations on data usage. Current data indicates that only 10% of large companies use AI agents, although 50% plan implementation within 12 months.
Industry Applications
In fraud prevention, AI systems are becoming more sophisticated. Mastercard has integrated AI across its network, processing 143 billion transactions annually. This technology is also transforming customer experience in financial services, delivering personalised interactions across various digital platforms.
‘[Gen AI] is the most important advance since the graphical user interface,’ stated Bill Gates, Founder of Microsoft.
