与2011年标普（Standard & Poor's）调降美国AAA级信用评级时的政治僵局不同，这一次部分议员（尤其是共和党议员）一直对此漠不关心。
但他指出，如果美国违约，对美元的影响会截然不同。违约发生后，经济中流通的现金将出现严重短缺，因为美联储（U.S. Federal Reserve）用于在金融机构之间转移资金的电子网络无法结算违约证券交易。回购市场以及由美国国债作为抵押担保的贷款将会冻结。
In a long-awaited breakthrough, Congress is inching closer to a deal that would increase the nation's borrowing limit and end a two-week-old government shutdown. The U.S. may just barely miss a default days before the U.S. Treasury exhausts its ability to borrow, but the sigh of relief could be short lived.
As the Washington Post reports, the Senate's Republican caucus is scheduled to meet at 11 a.m. Tuesday to consider an emerging deal, which if finalized, could extend the Treasury's borrowing power until Feb. 7, reopen the government, and fund federal agencies through mid-January. Months from today, it wouldn't be surprising if Congress stalls over the debt ceiling again. Only next time the U.S. may not be so lucky, and the latest debt ceiling debacle offers a good glimpse as to why.
Unlike during the political gridlock in 2011 when the U.S. lost its stellar credit rating from Standard & Poor's, some lawmakers (Republicans, in particular) have been downright blasé about it all this time around.
They've been playing down the significance of hitting the debt limit -- Sen. Rand Paul of Kentucky says the U.S. can avoid default by putting aside funds to pay bondholders. That may sound fine at first, but it effectively suggests other expenses, such as payments to Social Security recipients, could take a back seat. That would be scary because not paying your bills obviously isn't a good way to get yourself in good financial condition.
And for the U.S. government to skip its financial obligations would be catastrophic for the U.S. dollar.
In an article in Project Syndicate, University of California economist Barry Eichengreen lays out the implications of a default on the world's reserve currency. The result would be a sharp drop in the dollar combined with huge losses for financial institutions.
"Even if the Treasury paid bondholders first -- choosing to stiff, say, contractors or Social Security recipients -- the idea that the U.S. government always pays its bills would no longer be taken for granted," says Eichengreen, who writes frequently about the demise of the dollar. "Holders of U.S. Treasury bonds would begin to think twice."
Already, the world's central banks are losing faith in the world's richest country; officials are preparing for a U.S. default some say could happen at any time. The dollar's decline would be felt across the world, causing the value of smaller currencies to spike. It would also hurt emerging market economies, causing currencies from South Korea to Mexico to shoot up and therefore make whatever they sell abroad more expensive and much less competitive.
This sounds pretty awful, but it's easy to see why some folks in Washington aren't convinced. When the subprime-mortgage crisis hit, it was widely forecast that the greenback would tank, but that never happened. Eichengreen notes the dollar actually strengthened as investors scrambled for safety in U.S. Treasury bonds. That also happened a year later when Lehman Brothers went under.
But a default would be different, he argues. There would be a serious shortage of cash circulating the economy, as the electronic network operated by the U.S. Federal Reserve to transfer funds between financial institutions isn't set up to settle transactions in defaulted securities. The repo market, loans offered against Treasury bonds, would freeze up.
