Additionally, the US rolled another $513 billion in short-term debt: a number which continues to be persistently high, even as the total amount of short term debt as a percentage of total has declined steadily from 30%+ of total to around 20% as we have written elsewhere. Another $106 billion in Notes was rolled as well, with the intramonth cash balance dropping to a dangerous sub-$5 billion.
For the 11 months ending August 30, the US has paid $180 billion in interest expense in a time of record low interest rates.
At the current rate, we expect that the statutory, and completely irrelevant, debt limit of $14.3 trillion will be breached in the first two months of 2011. At that point total federal debt as a % of US GDP will be roughly 100% in its purest definition, and the inevitable greenlighting by Congress to raise the ceiling then will means that America is fully sliding into a debt-to-GDP ratio of >1.
