The federal government has four days left to raise the nation's current $14.3 trillion debt ceiling, the Treasury Department said. A failure to do so will risk an unprecedented national default.
If the debt ceiling is not raised by Tuesday, Americans could face rising interest rates and a declining dollar, among other problems.
As the cost of borrowing rises, individual mortgages, car loans and student loans could become significantly more expensive. Some financial experts have warned of a downgrade of America's triple-A credit rating and a potential stock market crash.
Without an increase in the debt limit, the federal government will not be able to pay all of its bills next month. President Barack Obama recently indicated he can't guarantee Social Security checks will be mailed out on time. Other critical government programs could be endangered as well.
Senate Democrats on Friday blocked the latest House Republican proposal to cut spending and increase the federal debt ceiling, setting up a weekend of negotiations to seek a deal that would avoid a potential federal default next week.
Earlier Friday,Â House Republicans passed Speaker John Boehner's latest proposal, overcoming opposition from Democrats and tea party conservatives. But Democrats had vowed to defeat it in the Senate, where they have the majority.
Boehner's plan calls for $917 billion in savings over the next decade, while creating a special congressional committee to recommend additional savings of $1.6 trillion or more. It would allow the debt ceiling to be increased by a total of roughly $2.5 trillion through two separate votes. The $2.5 trillion total would be enough to fund the federal government through the end of 2012.
The plan originally called for a congressional vote on a balanced budget amendment to the Constitution by the end of the year. Boehner has since reached out to disgruntled conservatives by amending the plan to require congressional passage of such an amendment as a condition for raising the debt limit by the full $2.5 trillion, according to two GOP congressmen.
The vote was scheduled to have taken place on Thursday night,Â but Republican leaders postponed the vote amid signs they did not have enough support to pass it.
Senate Majority Leader Harry Reid's plan would reduce federal deficits over the next decade by at least $2.2 trillion while raising the debt ceiling by $2.7 trillion. Reid has promised additional cuts will be included in the final version of his legislation - enough to meet the GOP's demand that total savings should at least equal any total debt ceiling hike.
Reid's plan would cut spending by $1.8 trillion. Roughly $1 trillion in the savings are based on the planned U.S. withdrawals from military engagements in Afghanistan and Iraq.
Reid's plan also would establish a congressional committee made up of 12 House and Senate members to consider additional options for debt reduction. The committee's proposals would be guaranteed a Senate vote with no amendments by the end of this year.
Reid said Friday morning that he "must take action" on the Senate's legislation by the end of the day.
Obama has endorsed Reid's plan and threatened a veto of Boehner's plan. The president strongly opposes any bill which doesn't raise the debt ceiling through the 2012 election. Obama has promised to veto any short-term debt ceiling extension unless it paves the way for a "grand bargain" of more sweeping reforms and revenue increases.
On Friday, Obama urged Senate Democrats and Republicans to take the lead in congressional negotiations. He said the House GOP plan "has no chance of becoming law." Obama also urged Americans to keep contacting members of Congress in order "to keep the pressure on Washington."
The president made a nationally televised plea for compromise Monday night, though he also criticized Republicans for opposing any tax hikes on the wealthy.
