Yellen gave a sense of the turmoil it would cause in her letter to House Speaker Kevin McCarthy on Monday. A close call in 2011 roiled the financial markets and prompted Standard & Poor’s to downgrade the US’ credit rating to AA+ from AAA.

Just what would happen if the nation defaults on its debt is unknown since it’s never actually happened before. The US hit its $31.4 trillion debt ceiling in January, and Treasury has been using cash and “extraordinary measures” to satisfy obligations since then. However, the forecast was uncertain, and the default date might come several weeks later, she said. Treasury Secretary Janet Yellen warned Monday that the government may not be able to pay all of its bills in full and on time as soon as June 1.

President Joe Biden and House Republicans may have as little as a month to prevent the US from defaulting on its debt, which would impact millions of Americans and unleash economic and fiscal chaos here and around the world.
