NEW YORK ( TheStreet) -- A much-awaited catalyst for bank stocks is finally here. After the market close on Thursday, the Federal Reserve will release the results of its 2013 bank stress tests, assessing whether the nation's 19 largest banks would be able to withstand a significant deterioration in economic conditions. Then, on March 14, the regulator will reveal which of the 19 largest banks will be allowed to raise dividends or repurchase shares. Banks will have to show that they can absorb substantial losses under adverse scenarios, pay out dividends or buy back shares and still maintain Tier 1 common equity ratios of at least 5%. The Fed's "severely adverse" scenario features an unemployment rate of 12%, a decline in GDP of 5% between the third quarter of 2012 and 2013 and a 20% decline in housing and commercial real estate prices by the end of 2014. For the first time, banks will have the option of lowering their capital return requests before the results are officially released to improve their chances of winning approval.

Goldman Sachs analysts said in a report Monday that almost all banks undergoing the annual review will announce higher capital returns in 2013, given that capital levels are higher than last year, loan books have been further de-risked and the stressed economic scenarios are less severe compared to last year. Still, "investors should expect gradual, not outsized, increases in capital return" the analysts said. The management commentary at most banks has suggested that they will be conservative in their capital return requests. "Management teams do not appear to view 'taking a mulligan' as a viable option (i.e., resubmitting their CCAR request with lower capital payouts after their original plan was rejected by the Fed), as they believe a public failure would reflect poorly on their risk management practices and perhaps damage their relationship with regulators," the analysts said. Banks have indicated that they would like to increase dividend payout ratios before opting to buy back more shares.
