J.P. Morgan (JPM.US) market share grew for a decade, resulting in an upgrade in credit rating by Standard & Poor's.

S&P Global, Inc. rating agency has upgraded JPMorgan Chase's long-term issuer credit rating to A with a stable outlook, indicating the bank's ability to withstand economic changes after years of competing for market share with its rivals. In a statement, S&P said, "The strength and consistency of JPMorgan Chase's diversified business supported our rating upgrade, making it one of the highest-rated banks globally. JPMorgan Chase's strong market share enables it to generate a high level of pricing power, customer choice, and economies of scale, which is stronger than almost any other International Bancshares Corporation." Analysts estimate that under the leadership of 68-year-old CEO Jamie Dimon, JPMorgan Chase achieved its highest annual profit in Bank of America Corp's history last year, with the potential to exceed this level by around 15% in 2024. Meanwhile, S&P noted that JPMorgan Chase has been strengthening its balance sheet and investing in new technologies, which could help lay a foundation for future profits and support its risk management capabilities. JPMorgan Chase's stock price has risen by 44% this year as investors bet that the incoming Trump administration would seek deregulation to boost bank profits, leading to a recent surge in the bank's stock price. However, S&P stated that this was not a contributing factor to its rating upgrade. S&P said, "The level of U.S. regulatory scrutiny remains a significant consideration in our ratings for JPMorgan Chase and other banks. Enhanced regulation of banks since the global financial crisis is not expected to substantially ease in the coming years."
