Many financial institutions are overlooking core infrastructure requirements for deploying AI at scale.
Despite increased technology spending, 41% of banks lack a centralized or optimized data foundation to support AI initiatives, according to a September report by data and software provider SAS.
Data lineage is an often overlooked component when building AI infrastructure, Sathishkumar Palanisamy, expert enterprise architect at Capital One, said at the recent FinAi Banking Summit in Denver. In AI modeling, data lineage refers to the end-to-end tracking of data origins, changes and destinations, according to IBM.
“The moment when your model makes a trading decision or flags a transaction, someone is going to ask, ‘Where did the number come from?’” Palanisamy said. “If your answer is going to be vague, then your AI governance is becoming a risk instead of a business advantage.”

FIs must view data lineage as a core infrastructure component, rather than just a reporting feature of audit trail, he said.
“Without that, scaling in banking becomes very tough,” he added.
While cloud computing and AI models continue to advance, an insufficient data pipeline could render such advancements useless, Andrew Braun, director of engineering and platforms at the $1.6 billion Grasshopper Bank, said at the event.
“If you don’t have the gas for your car, it’s not going anywhere. The data that’s going to make everything interesting and differentiate your content from competitors is the data that resides inside your structured and unstructured datasets and bringing that into AI is really the keys to the kingdom.”

Institutional knowledge a must
Undocumented institutional knowledge is another hindrance to infrastructure development, Madeline Fredin, vice president of partnership strategy at Alloy Labs, a collaborator with FIs, said at the event.
Institutional knowledge is important because it affects how information is stored and the explainability of AI models, she said.
For example, an FI may lack a specific policy for how Microsoft Copilot is used, creating inconsistencies and inaccuracies in the system.
“That’s not an AI problem, that’s an infrastructure and procedures problem,” Fredin said.
While agentic AI is taking some pressure off institutional knowledge documentation, “the rationale for all of that institutional knowledge that surrounds it is missing in most institutions,” she said.
