Wall Street's revival in the second quarter was driven by a surge in investment banking fees at major banks like JPMorgan Chase, Citigroup, and Wells Fargo, as well as increased trading revenue. This comes after a two-year slump in dealmaking, with factors such as rising interest rates, geopolitical tensions, and an uncertain presidential election outcome contributing to improved market conditions.

JPMorgan's investment banking revenues surged 50% from last year to $2.35 billion in the second quarter. This increase was driven by a revival in dealmaking and strong capital markets activity.

Net interest income fell at major banks due to higher interest rates and elevated deposit costs, which impacted traditional consumer banking margins. Customers migrated to higher-yielding deposit products like CDs, leading to a decline in net interest income, a key measure of lending revenue.
