With the U.S. headed toward the “dangerous moment” of default, uncertainty over the government shutdown and debt ceiling continues, after talks to resolve the issues folded Saturday between the Senate’s top two leaders.

Besides keeping some 350,000 federal workers idle for nearly two weeks, the stalemate prompted a GOP prediction that the United States might not make its credit obligations on Thursday. That led president of the World Bank to warn of an international financial “crisis.”

“We are now five days away from a very dangerous moment,” World Bank chief Jim Yong Kim said at the close of the annual World Bank-International Monetary Fund meetings in Washington. “The closer we get to the deadline, the greater the impact will be for the developing world.”

Senate Minority Leader Mitch McConnell of Kentucky and Democratic Majority Leader Harry Reid of Nevada met for 30 minutes on Saturday, with no resolution. Still, “we had a good meeting,” McConnell told reporters. He made no further comment.

No additional talks were scheduled, a McConnell aide told Newsmax, but Republican Sen. Bob Corker of Tennessee said that the senators would “continue to talk over the weekend.”

“Again, it is very evident that the White House is not going to be involved in negotiations, at least at this point they are not, and that the centerpiece is Reid and McConnell,” Corker told CNN. “So I think all of us want to support those efforts, and hopefully they bear fruit over the weekend.”

McConnell and Reid met for the first time since the partial government shutdown began 12 days ago, idling as many as 350,000 federal employees.
