The following tables are taken directly from the U.S. Treasury's Monthly Statement and provide a running account of activity month to month and year to year. Annual interest is paid against the previous year's closing balance and half is paid in December, half in June. The interest rate is taken from the Bureau of Public Debt and is the average for the year. As a result, there may be small discrepancies in the amount of interest paid the trust with no money involved.

Pay particular attention to the month of September, the close of the government's fiscal year. The influx of bonds does not come from interest or employee contributions that are reflected in the continuous flow of monthly deductions from paychecks recorded under "receipts." But no one will admit where it does come from.

* This is not interest. This number comes from the Treasury's Financial Management Service (FMS) and, thanks to Barack Obama for telling them to talk to me, it is called dollar-for-dollar "matching funds" deposited against the total receipts from employees and confirming the "winging it" section at the end of this web page. In fiscal 2006, this deposit was exactly $28,150,636,202 or $28.2 billion. Translation: The government spent the contributions from its own emplyees and, in September, adds nonmarketable bonds to the account just as they do every month with Social Security. It is always enough to increase the trust fund for the year even though the program was in the red every month.
