Major U.S. banks begin third-quarter earnings reports this week as multi-decade high Treasury yields and elevated oil prices test the banking sector. JPMorgan, Goldman Sachs, Citigroup, and Wells Fargo report Tuesday before market open, with Bank of America and Morgan Stanley following on Wednesday. Market focus has shifted to credit demand, deposit costs, capital markets activity, and asset quality to assess the impact of sustained high rates on businesses and consumers. Analysts project all six banks will post year-over-year EPS growth, with some potentially reaching 20%. Despite expected profit gains, bank stocks have already reflected market concerns. The KBW Bank Index dropped approximately 13% from its August closing high and fell 6% cumulatively in Q3, while the Invesco Bank ETF declined over 12% since hitting a record high on August 14.
