The total national debt of $14.4 trillion exceeded the $14.3 trillion ceiling in July 2011. US is in mess since 2008 and the situation is regarded as a crisis due to the potential for a major worsening of the economic status of the US in the case of a government default, such as rising borrowing costs or disruption if the government cannot pay its bills.

Credit rating agency Standard & Poor's placed US debt ratings under "negative credit review" during the crisis, increasing the risk of a downgrade to the US "AAA" credit rating.

As of May 2011, approximately 40% of US government spending relied on borrowed money.
