Financial industry executives are dealing with an onslaught of regulations intended to improve the safety of the financial system. David Reilly explains how the rules are sometimes contradictory and often confusing, prompting executives to question the endgame. Meanwhile, the banks face upcoming "stress tests," which will be conducted by the Federal Reserve. The Fed is keeping the details under wraps to ensure they can't be gamed. "[W]ith a limited view into these tests and without knowing regulators' ultimate aim for big banks, investors are being told to simply trust in the Fed," Reilly writes.
