Her note of conciliation helped lift prices of Argentine bonds. Still, dangers remain. The ruling said that if Argentina didn't give the plaintiffs all the money they're due, it couldn't use U.S. banks to make its other interest payments, which are due June 30.
One misstep and Argentina could slide toward another default, which would likely spread trouble beyond its shores.
Just how did Argentina wind up in this mess? Here are some questions and answers:
Q: What happened after the Supreme Court turned Argentina down?
A: A lot. The Supreme Court also decided to let bondholders subpoena banks in U.S. courts to track down Argentina's assets abroad. The decisions drove the country's Merval stock index down 11 percent on Monday.
The next day, the rating agency Standard & Poor's cut Argentina's rating further into junk territory — to CCC-, S&P's lowest grade for any country.
For most countries, the rating agency's move would be a harsh blow. It would inflate borrowing costs and make it harder to finance budgets. But Argentina's troubles are so well-known that the downgrade came as little surprise. Argentina hasn't borrowed from the bond markets since its default in 2001.
Q: Who are the players?
A: In one corner, Argentina's government. In the other, a group of investors led by NML Capital, a subsidiary of Elliot Capital Management, run by billionaire Paul Singer. Singer, a lawyer by training, has in the past successfully sued the governments of Peru and the Republic of the Congo to make good on their bonds. In this case, NML and other funds bought bonds left from Argentina's default in 2001.
Q: What do they want?
A: When the hedge funds bought the defaulted bonds, they joined the ranks of Argentina's creditors. Now, like lenders everywhere, they want the borrower to repay its debts on the original terms.
Problem is, other creditors had already agreed to cut Argentina a break in 2005 and 2010 by swapping their bonds for new ones worth less. This helped Argentina's government slash its debts.
The bonds acquired by Singer's group were among those left over. In 2012, U.S. District Judge Thomas Griesa in New York ordered Argentina to pay the holdouts. They're now owed $1.5 billion in principal and interest.
Q: Why is a U.S. court telling a foreign government what to do?
A: When a big business goes bust, it winds up in bankruptcy court. By contrast, sovereign countries have no dedicated international court to help them strike deals with creditors. So in agreements involving bond sales, language typically stipulates that any legal battle must occur in one of the two biggest financial capitals: New York or London. "That's where the money is," said Anna Gelpern, a professor of international law at Georgetown University and an expert on government debt.
