Some senators from the South still wear linen suits and believe that foreign interests should not own land or a part of any business in the U.S. They also probably still smoke and eat fatty foods.

But the serious side of congressional concern about overseas investments in big U.S. companies and financial firms is that sovereign funds could find a more and more hostile reception to their investments in companies like Citigroup (NYSE: C).

According to the FT, "The Treasury, which considers the discussions with the funds a priority, hopes it can pursue its agenda through the International Monetary Fund, which is drawing up a code for SWF investments, expected in draft form in April." The document is probably no more than a "feel good" piece of paper that Treasury can wave around in the offices of Congress and regulators.

The fact of the matter is that the government here would like sovereign funds to have different rules than those that govern people like Carl Icahn. If a raider can take over an entire company and break it into pieces, why can't the same be done by rich interests from Kuwait, if they have the money? Any "state secrets" at a firm like Citi can be burned before the process starts, in the name of keeping important government data confidential.

The bonfire from the documents can warm the management as they leave the building.
