AI Gains for Big Banks Pose a Competition Headache

Bank of America Corp. first launched its artificial-intelligence driven chatbot, Erica, nearly a decade ago in 2016. Several iterations and a wealth of patents later, the platform handles about 2 million customer interactions each day, the equivalent of what 11,000 employees could do.

If that sounds impressive, the flipside is the cost: the company has spent nearly $120 billion on technology over roughly the same period, and last year’s $12 billion tech budget included $4 billion for development, including improving Erica and building new apps, on top of the $8 billion required to maintain existing systems. These are huge sums and investors in many big banks have long asked what returns they’re getting for this cash. It’s good that some answers are starting to emerge — but they’re somewhat limited and there are two important warnings in this story.

First, costs are high in part because companies must be extremely cautious in deploying new tools, especially generative AI, because mistakes can be ruinous for trust and waste the investment. Second, AI promises to turbocharge competition problems because it looks likely to put even greater distance between the largest lenders that can spend the most and the rest of the pack.

Bank of America is a case in point: Its yearly tech budget is greater than the entire cost base of more than half the lenders in the KBW Banks index. JPMorgan Chase & Co.’s $18 billion annual tech spend is greater than total expenses at all but five other banks in the index.

Details on what gains BofA has got for its money were the most interesting parts of last week’s investor day, its first since 2011. The bank’s consumer arm has cut staff to 55,000 this year from 101,000 in 2011, entirely due to better technology, it said. Since 2018, it’s also slashed fraud losses across the bank by half, it added.

AI has been a big part of this. BofA has built everything itself rather than using Silicon Valley firms, which has made it one of the biggest owners of intellectual property in finance alongside Capital One Financial Inc. These two account for 65% of all AI-related patents owned by banks, according to analysts at Wells Fargo & Co.
