JPMorgan Chase CEO Jamie Dimon warns of prolonged inflation and higher interest rates due to factors like fiscal deficits, infrastructure needs, and global tensions. Despite recent easing, Dimon cautions that inflationary pressures persist, potentially necessitating interest rate cuts by the Federal Reserve. Concerns about growing U.S. deficits, reaching $1.9 trillion, align with Dimon's warnings about economic challenges. Dimon's remarks follow improved second-quarter profits for JPMorgan Chase, driven by strong investment banking performance and a one-time accounting gain, with net income reaching $18 billion.
