In the high-stakes world of finance, Jamie Dimon, CEO of JPMorgan Chase, has signaled that his retirement is closer than ever. This marks a significant shift in messaging during the bank’s investor day.

Dimon, who is 68 years old, has been at the helm of JPMorgan for 18 years. His leadership has seen the bank grow into the largest of its kind in the U.S. by both assets and market cap. However, in response to a question about the bank’s succession planning, Dimon indicated that his expected tenure is less than five more years.

This change in Dimon’s retirement timeline has made succession timing at JPMorgan one of the persistent questions for the bank’s investors and analysts. Despite the uncertainty, Dimon reassured that he still has “the energy that I’ve always had” in managing the sprawling company.

The decision of when he moves on will ultimately be up to JPMorgan’s board. Dimon encouraged investors and analysts to examine the executives who could take his place. Atop the short list of candidates is Marianne Lake, CEO of JPMorgan’s consumer bank, and Jennifer Piepszak, who co-leads its commercial and investment bank.

Even when he steps down as CEO, it is likely he will stay on as the bank’s chairman. This transition period will be a crucial time for JPMorgan as it navigates the future of its leadership and continues to maintain its position in the financial industry.
