The head of the International Monetary Fund says that a default by the United States on Thursday could send the world into a major recession.

Christine Lagarde said that the default would cause “massive disruption the world over” during an interview for ABC’s Meet The Press.

“If there is that degree of disruption, that lack of certainty, that lack of trust in the US signature, it would mean massive disruption the world over and we would be at risk of tipping yet again into recession,” Lagarde said.

Jim Yong Kim, president of the World Bank, also expressed concern over the situation saying that the U.S. is “days away from a very dangerous moment.”

Multiple finance ministers for European nations told the BBC they don’t expect the U.S. to default but are very uneasy and would like to see the crisis to end soon.
