America’s largest banks are entering a new phase of technology adoption, one in which artificial intelligence is no longer viewed as an experimental tool but as a foundational driver of productivity. Speaking at a major financial services conference, executives from JPMorgan Chase, Wells Fargo, PNC Financial, Citigroup and Bank of America made clear that AI is accelerating efficiency gains across nearly every operational layer—and that these gains will inevitably affect staffing levels over time.

Their message was consistent: AI is becoming essential to running a modern financial institution. Yet as it automates more processes, streamlines customer interactions and enhances decision-making, the technology is also setting the stage for structural shifts in how banks deploy human labor.

AI Productivity Gains Are Already Material

JPMorgan’s consumer and community banking chief Marianne Lake offered one of the most concrete measures of AI’s impact. She said the bank has doubled productivity—from 3% growth to 6%—after deploying AI across large portions of its operations. In specialized back-office functions, she expects productivity improvements of 40% to 50% as automation scales.

According to Lake, higher productivity does not automatically result in sweeping job reductions, but she acknowledged that the net demand for certain roles will gradually decline as AI handles more routine work. For a bank with more than 300,000 employees, even marginal efficiency gains translate to significant organizational changes.

Wells Fargo CEO Charlie Scharf struck a similar tone, noting that while the bank has not reduced its workforce, the volume of work completed per employee has meaningfully increased. Scharf added that AI will help the bank “do more with fewer people” in many areas, though not replace humans entirely. Instead, it is reshaping how work gets done.

Automation Has Been Building for a Decade—but AI Is an Accelerant

PNC CEO Bill Demchak highlighted that his bank employs roughly the same number of people it did 10 years ago—even though it is now three times larger. That efficiency has been achieved through automation, branch restructuring and process optimization. AI, he said, will only accelerate that trend, especially as demand grows for technical talent capable of developing and deploying advanced systems.

Citigroup executives echoed this view. Incoming CFO Gonzalo Luchetti said the bank has seen a 9% productivity increase in software development thanks to generative AI. He added that AI is already improving the call-center experience by assisting agents in real time, allowing them to resolve issues more quickly.

Goldman Sachs and Bank of America are simultaneously leaning into the shift. Goldman has signaled job cuts as part of its “OneGS 3.0” AI strategy, while Bank of America plans to spend billions on AI to boost banker productivity and expand revenue opportunities.

The Workforce Impact Is Clear—Even if the Timeline Isn’t

The banking industry’s message is unmistakable: AI is transforming operations, and the efficiencies it unlocks will gradually reshape staffing models. While banks remain cautious in how they frame the job impact, the direction of travel is evident. Productivity growth driven by AI will be a defining force in U.S. financial services—one that creates new technical roles while compressing demand for traditional operational jobs.
