The debacle sparked new fears about big banks and prompted Dallas Federal Reserve Bank President Richard Fisher, who has called for the breakup of the top five U.S. banks, to say he is worried the biggest banks do not have adequate risk management.
The fallout extended across much of the banking sector, with shares of some of Wall Street's top names declining on Friday. Among others, Citigroup dropped 4.2 percent, Goldman Sachs fell 3.9 percent and Bank of America slipped 1.9 percent.
JPMorgan was far away the worst performer, however, falling 9.3 percent on a day when some 212 million of its shares traded, the most volume in its history.
Fitch Ratings downgraded JPMorgan's debt ratings by one notch and put all of the ratings of the bank and its subsidiaries on negative ratings watch.
While Fitch saw the size of the loss as manageable, "the magnitude of the loss and ongoing nature of these positions implies a lack of liquidity," the ratings agency said. "It also raises questions regarding JPM's risk appetite, risk management framework, practices and oversight; all key credit factors."
"Fitch believes the potential reputational risk and risk governance issues raised at JPM are no longer consistent with an 'AA-' rating," it said.
