Monday morning has greeted the Street on an optimistic note toward large banks, as Goldman Sachs (NYSE: GS) has upped its coverage on the banking sector to "attractive" from "neutral." Goldman went as far as to name some specific banks, including Wells Fargo (NYSE: WFC), which it upped to "buy."

Goldman believes that Wells Fargo's capital position is improving, with it eventually benefiting from its takeover of Wachovia. The brokerage stated that Wells Fargo purchased Wachovia at a "distressed price" and that will help its assets increase 70% from the second quarter of 2007 to the second quarter of 2009.

The U.S. Treasury and Congress are putting pressure on the Fed to disclose its governance policies.

Almost three months ago, on June 17, the Obama administration proposed a regulatory overhaul including a "comprehensive review of the Fed's ability to accomplish its existing and proposed functions."

There is some confusion as to why the Treasury is undertaking this task. The Fed was created by Congress to be independent of the executive branch and Congress.

A look at NYSE short interest as of February 15 shows that short sellers are still willing to make very large bets that bank stocks will go lower.

Shares sold short in Wachovia (NYSE: WB) rose 16.3 million between January 31 and February 15. For Citigroup (NYSE: C) shares short rose 10.9 million to 92.8 million. At Bank of America (NYSE: BAC) the number was up 6.3 million to 68.8 million.

Even with bank stocks trading near multi-year lows, a number of investors are anticipating more bad news as banks file their 10Ks for 2007 and announce their 2008 first quarter results. The short sellers have a fairly good chance of making a killing.

Big banks still have several things going against them. As the mortgage market gets worse, they may have more subprime write-downs. A drop in the credit rating at a bond insurer like MBIA (NYSE: MBI) could force the banks to write-down securities that rely on AAA ratings for some of their value. Perhaps the most important liability banks have not faced is the declining value of financial instruments based on auto loans and credit card balances.

The world is likely to get much worse for big banks and short-sellers are likely to make money on that.
