JPMorgan Chase on Friday reported first-quarter profit and revenue that roundly beat expectations, boosted by a year of rate hikes from the Federal Reserve. The New York-based bank posted a profit of $12.6 billion or $4.10 per share. That’s up from $8.3 billion, or $2.63 per share from the same period a year before. With $3.67 trillion in assets, JPMorgan Chase is the largest bank in the United States and a bellwether for the US economy. Deposits rose to $2.38 trillion during the first quarter from $2.34 trillion in the quarter ended in December.
