During early deals on Wednesday, the Japanese yen climbed to new multi-day highs against its major counterparts as investors sought safety in the Japanese unit on speculation the Federal Reserve's stress tests may show U.S. banks will need more capital to withstand a deeper slump.

Worries about capital shortfalls in US banks which undergone stress tests to check their financial soundness have sent US stocks lower Tuesday and dampened market sentiment in Asia today.

US banking regulators and the Federal Reserve are set to release results of the stress tests on Thursday.

The U.S. government is expected to direct about ten of the nineteen banks that have undergone stress tests to bolster their capital. The report noted that move is expected to help quell fears about the solvency of the financial sector.

The nineteen major financial institutions that were scrutinized through the government's stress tests were intimated with preliminary results last week. Regulators are now negotiating these results and any capital recovery plans with the banking companies. The complete results were originally scheduled to be published on May 4, but have been delayed, partly over a disagreement by banks over the results of the tests. The results are now slated to be released tomorrow.

The stress tests began in late February as a way to determine whether or not the banks had sufficient capital to navigate the difficult financial environment. According to a Fed study released April 24, the banks in the test hold two-thirds of the assets and more than half of the loans in the U.S. banking system.
