Barack Obama may lose the advantage of low borrowing costs as the U.S. Treasury Department says what it pays to service the national debt is poised to triple amid record budget deficits.
Interest expense will rise to 3.1 percent of gross domestic product by 2016
, from 1.3 percent in 2010 with the government forecast to run cumulative deficits of more than $4 trillion through the end of 2015, according to page 23 of a 24-page presentation made to a 13-member committee of bond dealers and investors that meet quarterly with Treasury officials.
“It’s a slow train wreck coming and we all know it’s going to happen,” said Bret Barker, an interest-rate analyst at Los Angeles-based TCW Group Inc., which manages about $115 billion in assets. “It’s just a question of whether we want to deal with it. There are huge structural changes that have to go on with this economy.”
The amount of marketable U.S. government debt outstanding has risen to $8.96 trillion from $5.8 trillion at the end of 2008, according to the Treasury Department. Debt-service costs will climb to 82 percent of the $757 billion shortfall projected for 2016
from about 12 percent in last year’s deficit, according to the budget projections.
That compares with 69 percent for Portugal, whose bonds have plummeted on speculation it may need to be bailed out by the European Union and International Monetary Fund.
