After the last recession and the collapse of the housing market in the U.S., the Dodd-Frank financial reforms were put into place. Part of the legislation requires that, once a year, the big banks are put through a "stress test." But what kind of test is this, and is it really all that relevant?

In no way, however, do they insure that banks will be ready for the next recession, which may look entirely different.
