While investors speculate on the Federal Reserve's actions in September this year, analysts at Fitch Ratings have issued a warning about a new threat to the US banking system. The risk of sharp downgrades to the ratings of dozens of American banks, including major ones like JPMorgan Chase, has come under the spotlight.

Following a series of studies, the rating agency downgraded its assessment of the industry in June. The move went largely unnoticed, as it did not result in any actual downgrades of banks. However, experts are genuinely concerned about the potential for more serious problems ahead, with a significant probability of a one-notch downgrade to A+ from AA- looming.

Market rumors are swirling that Fitch might soon have to reassess the ratings of over 70 American banks. It's worth reminding that credit rating agencies, on which many bond investors rely, have recently caused market turbulence with their moves. Last week, Moody's lowered ratings for 10 small and medium-sized regional banks and warned that more cuts could affect another 17 creditors, including larger institutions like Truist and Bank of America.

Earlier this month, Fitch downgraded the long-term credit rating of the US due to political turmoil and rising debt, a move criticized by business leaders including JPMorgan CEO Jamie Dimon and US Treasury Secretary Janet Yellen.
