Wall Street Banks More Dangerous

Just how big are the biggest US banks, and how safe are they? When trying to figure all that out, it makes a big difference if you are analyzing them according to US accounting standards or international ones. The latter makes lenders account for a greater portion of risky derivatives on their balance sheets.
Take JPMorgan, for instance. Under US accounting rules, the bank is just the fourth largest in the world with total assets of $2.3 trillion and capital equal to roughly 7% of total assets. But under international rules where lots of off-balance sheets assets like derivatives are accounted for, according to Bloomberg, JPMorgan would be the largest in the world with assets of $4.5 trillion and capital equal to less than 4% of assets. The higher capital ratios are, the less likely banks are to face liquidity and solvency problems.
