The Transformative Role of AI in Financial Services: Insights from Mastercard

The financial services landscape is undergoing a significant transformation as generative artificial intelligence (AI) shifts from a conceptual novelty to a practical and commercialized tool. According to Mastercard’s latest Signals report, AI is revolutionizing the banking and payments sectors by enhancing operational efficiency and customer experience, as stated in Fintech Magazine.

Generative AI has evolved significantly since its mainstream debut in 2021. Today, financial institutions are focusing on its commercial applications. Microsoft founder Bill Gates describes generative AI as “the most important advance since the graphical user interface.” Meanwhile, OpenAI CEO Sam Altman acknowledges both its potential and associated risks, stating he is “a little bit scared” of the technology his company has pioneered.

Mastercard’s Signals report highlights three critical advancements in AI deployment:

1. Informed AI, which combines large language models (LLMs) with external data sources.
2. Perceptive AI, capable of interpreting environmental data.
3. Proactive AI, which operates autonomously with minimal human intervention.

Banks and payment providers are leveraging informed AI through two primary techniques: fine-tuning and retrieval-augmented generation (RAG). While fine-tuning involves training AI systems on specific datasets, RAG allows real-time access to external databases. The choice between these methods depends on factors such as data quality, update frequency, and security.

In highly regulated industries like finance and law, protecting proprietary information is a priority. Currently, 20% of enterprises employ fine-tuning, while 80% rely on RAG for their AI systems. These technologies have proven critical for tasks such as fraud detection, transaction analysis, and personalized financial advice.

For example:

• Cohere provides RAG capabilities tailored to business needs.
• Unstructured develops tools to convert unstructured data into RAG-compatible formats.
• Glean offers an AI assistant that uses RAG to surface relevant information for financial professionals.

Generative AI has already made a significant impact:

• 73% of mortgage lenders consider it essential for enhancing lending processes by incorporating market trends into underwriting.
• Financial institutions are increasingly using AI for fraud monitoring, portfolio management, and personalized advice.

Mastercard has integrated AI into its operations, analyzing 143 billion transactions annually. The company’s Decision Intelligence Pro solution evaluates over a trillion data points each year to detect fraudulent activity, achieving an average 20% improvement in fraud detection, with some cases seeing a 300% increase.

Despite its benefits, AI implementation in financial services faces technical and regulatory challenges. Banks must ensure that AI operates on a zero-retention basis to protect sensitive data. Poor data quality and insufficient security measures can lead to errors and breaches.

Proactive AI systems are gaining traction, automating tasks with minimal human oversight. Currently, 10% of large companies use AI agents, with 50% planning to adopt them within the next year. These systems streamline processes like portfolio management and customer onboarding, reducing manual effort and improving efficiency.

Startups like Adept AI, which secured $350 million in funding in 2023, and Imbue, backed by Amazon’s Alexa Fund, are developing autonomous AI solutions tailored for financial operations.

Beyond fraud prevention, AI is transforming customer interactions. Mastercard’s Dynamic Yield product delivers hyper-personalized experiences across digital platforms, generating 371 billion impressions across 450 brands in 2023. AI-powered assistants are automating routine tasks like report generation, enabling financial professionals to focus on high-value activities.

Mastercard’s Signals report underscores the transformative potential of AI in reshaping the financial services sector. As adoption accelerates, informed, perceptive, and proactive AI are poised to redefine operational efficiencies, enhance fraud prevention, and deliver personalized customer experiences.
