Goldman CEO opposed to full bank nationalization

"I don't think that nationalization is a good solution. It is decisive that the financial system is being stabilized and governments have to act in a pragmatic manner," Lloyd Blankfein was quoted as saying.

"In extreme situations, it can be meaningful when the government takes a stake. However, full control should be avoided," he added.

Asked about the case of stricken German property lender Hypo Real Estate , which has already received 87 billion euro ($110 billion) in state guarantees, Blankfein said: "There can be extreme situations, where there is no alternative. Then the following must apply: If the tax-payer raises the whole capital of a company, it has to belong to him. Otherwise, the state is in danger of taking only risks, without having the opportunities."

Blankfein also commented on the cases of U.S. bank Citigroup -- in which the U.S. government will hike its stake to 36 percent -- as well as struggling carmaker General Motors .

Asked whether it would only be a matter of time until both companies would be fully nationalized, Blankfein said that, so far, both companies were still not completely state-owned.

"Secondly, the main point was to avert immediate threats. In the case of Citigroup, a real systemic risk for the financial markets had to be contained. In the case of General Motors, the social implications of a sudden breakdown would have been huge," he said.

The Bush administration in December approved a $17.4 billion bailout for GM and Chrysler LLC , requiring the administration of President Barack Obama to determine by March 31 whether both companies can be commercially viable.

Blankfein said that the company would remain committed to its business in Germany, adding that it is the "central economy in continental Europe and for us the bridge to eastern Europe."

He also pointed to uncertainty within the European Union with regard to state finances, particularly about who would contribute what, should a member of the EU run into financing problems.

"How much has to be raised by the single state and how much will be contributed by the European Union? Those questions are unanswered. Unanswered questions make the markets feel insecure."

The market crisis has highlighted differences between economies in the single euro zone with some countries, such as Ireland, seeing their deficits balloon and there has been much talk about how euro zone states can maintain solidarity.
