Treasury Secretary Tim Geithner says the U.S. will not lose its top-notch credit rating despite a massive federal debt that now tops $14 trillion and huge trillion dollar deficits.

Geithner says there's no way the U.S. rating will be downgraded.

"Absolutely not. And that will never happen to this country," he said. "And again, if you step back and look at what has happened throughout this crisis, when people were most worried about the stability of the world, they still found safety in Treasuries and the dollar."

Moody's Investment Service recently warned that the U.S. credit rating could eventually fall if the government does not get its finances in order.

The cost of borrowing would increase dramatically if the ratings service lowered the credit rating, also known as a bond rating, for U.S. Treasuries.
