Bank Bailout Could Cost Up to $4 Trillion

From CNBC:

The cost of restoring confidence in U.S. financial firms may reach $4 trillion if President Barack Obama moves ahead with a "bad bank" that buys up souring assets.

The figure far exceeds even the most pessimistic estimates of how great the loan losses might be because there is so much uncertainty about default rates, which means the government may need to take on a bigger chunk of bank debt to ease concerns.

Goldman Sachs estimated that it would take on the order of $4 trillion to buy troubled mortgage and consumer debt. That number could shrink if the program were limited to only certain loans or banks, but it could also grow if other asset classes such as commercial real estate loans were included.

New York Sen. Charles Schumer has said that a number of experts thought that up to $4 trillion may be needed to buy the bad assets, an estimate that a Senate aide said was based on informal conversations with people in the industry.

The Wall Street Journal said government officials had discussed spending $1 trillion to $2 trillion to help restore banks to health, citing people familiar with the matter.

At $4 trillion, that would be the equivalent of nearly 1/3 of U.S. gross domestic product. If the government had to fund that amount by issuing additional debt, it would intensify investor concerns about massive supply scaring off demand.
