Stress Test: Regulators Evaluating the Health of Big Banks

In August the U.S. Federal Reserve asked a number of big U.S. banks to undergo various "stress tests" in order to judge how their balance sheets could fare in worst-case financial scenarios.

The goal, as reported by CNBC, seems to be to assure that these companies can produce emergency capital given the sudden need.

U.S. banks interviewed by the Fed include Bank of America, JPMorgan Chase, Citigroup, and Morgan Stanley, according to CNBC's sources.

These interviews are a reaction to market volatility and the "too-big-to-fail" mentality.

"The summertime tests were a follow-up to a larger round of balance-sheet assessments that the country's 19 biggest banks undertook as part of the Comprehensive Capital Analysis and Review process that the Fed mandated in March, according to someone familiar with the matter."

Although the specific stress-stress scenarios are unknown, Bank of America "suggested to the Fed that it might introduce a Merrill Lynch tracking stock, among other things, say people familiar with BofA's proposal."

So we're wondering -- which U.S. banks offer relative safety for investors looking to gain exposure to the banking industry?
