JPMorgan Chase, the largest lender on Wall Street, said it plans to dramatically increase spending on technology and talent to fortify its competitive position, stirring investor worries about US bank earnings in 2022.

As it reported record profits last year, JPMorgan stunned analysts with a forecast that expenses would increase by 8 per cent this year to around $77bn, meaning it would probably miss a key profitability target in 2022, and possibly in 2023.

Part of the elevated expenses are from higher pay, with an extra $2.5bn earmarked for compensation and travel expenses. But JPMorgan also said it planned to increase new investments this year by $3.5bn, or 30 per cent, to almost $15bn. Technology spending in 2022 will hit $12bn in 2022, it said.
