JPMorgan Chase & Co. (JPM  ) CEO Jamie Dimon has cautioned against overly optimistic projections for the U.S. economy's performance in the coming years.

Dimon acknowledges the strength of the economy, supported by healthy consumer balance sheets and increasing wages, according to a report by CNBC on Monday. Yet he warns of potential risks looming ahead.

Dimon highlighted concerns such as the withdrawal of central banks' liquidity programs, the ongoing Ukraine conflict and excessive global government spending. While addressing a financial conference in New York, Dimon said it would be a "mistake" to assume a persistent economic boom.

Despite his warnings last year about a potential economic hurricane due to the same issues, the U.S. economy has demonstrated resilience. This resilience led to more economists expecting that a recession will be averted.

Dimon voiced his concerns, noting that JPMorgan has been buying back shares at a reduced pace, a trend that might persist into 2024. He also highlighted the worsening ties between the U.S. and China as a major point of worry.

Despite the U.S economy's defiance of expectations in the past year, Dimon stressed the substantial and dangerous uncertainties still present.
