The banking unit of JPMorgan Chase alone made $12.4 billion last year. The holding company has over $2.26 trillion in assets and is the largest U.S. bank and 8th largest in the world. The holding company made $29.9 billion in operating income and just over $20 billion in net income for 2011.
So, this initial loss of $800M [TC: with more to come] represents approximately 4% of its total net profit for all of 2011, less than 2.7% of its operating income. Certainly it’s not a good thing. But the reported losses, in and of themselves, are not likely to have a dramatic impact on JPMorgan’s long-term financial stability.
Addendum: Sober Look adds a good point.
