Four of the nation's largest lenders -- JPMorgan Chase & Co JPM.N, Wells Fargo WFC.N, Citigroup Inc C.N and Morgan Stanley MS.N -- will report third-quarter earnings Friday, Oct. 14. While rising rates tend to buoy bank profits, the broader risk of an economic downturn sparked by high inflation, supply-chain bottlenecks and the war in Ukraine could weigh on future earnings. Investment-banking powerhouse Goldman Sachs Group Inc GS.N is expected to report a 46% plunge in profits when it reports on Oct. 18, while earnings at rival Morgan Stanley are seen falling 28%.
