Wall Street's major banks, including Morgan Stanley, JPMorgan Chase, Citigroup, and Goldman Sachs, reported declining trading and investment banking revenues for the second quarter. The pandemic-induced market volatility had previously boosted trading revenues, but the gains have started to subside, leading to investor concerns. Uncertainty about the Federal Reserve's rate policy and a slowdown in corporate IPOs and deals have contributed to a more complicated picture for Wall Street businesses. While big banks have performed well amidst higher interest rates, regional banks face challenges, particularly in acquiring deposits and dealing with pressure on commercial real-estate loans.
