New Series: Treasuries outstanding by class (12/1868 - 10/2018)

I am pleased to announce a new monthly series on marketable nominal interest-bearing Treasuries outstanding by class.  The series is in billions of dollars and excludes debt issued on behalf of the Navy pension fund, Pacific Coast Railways, TIPS, and floating rate notes.  The series begins in december of 1868.  The source of the data are the monthly statements of the public debt.  One can now find the series on the data download page.
