You stress test a plane well before takeoff, BUT we stress test banks when they may be in a nose dive....

The Federal Reserve sought to bolster confidence in the U.S. banking system as concerns over the European sovereign-debt crisis roil financial markets and pose risks to the economic expansion.

The Fed yesterday told the 31 largest U.S. banks to test their loan portfolios against a deep recession to ensure they have enough capital to withstand losses. Banks with large trading operations will also test against a European market shock. The most severe scenarios outlined by the Fed include an unemployment rate of as much as 13 percent, an 8 percent drop in gross domestic product and a 52 percent plunge in stocks from the third quarter of 2011 to the fourth quarter of 2012.


“This is a daunting test,” said Karen Shaw Petrou, managing partner at Federal Financial Analytics, a Washington regulatory research firm whose clients include the largest banks. “The Fed’s credibility as a tough guy can’t be challenged based on this.”

The tests, which the Fed said don’t represent its outlook for the economy, aim at making banks’ capital adequacy more transparent by demonstrating whether they can handle a deeper downturn and financial market shock. The Fed helped clear away uncertainty surrounding banks in May 2009, when it published stress tests showing that 10 U.S. firms needed to raise a total of $75 billion, giving investors more clarity.
