Bond Data Files

The Office of Finance creates bond data files each weekday morning at 6:30 a.m., to be posted to this site by 10 a.m. Three sets of files are provided:

Type Naming Std Comments
Issuance dddxxxx.dat Contains bond settlements for a given day (Monday-Friday)
Change chgxxxx.dat Contains bonds that have had servicing activity on the most recent business day
Full allxxxx.dat Contains all outstanding bonds (posted weekly, every Friday morning)

A more detailed description of these data files can be found in the file specs document, in pdf file format.

These files provide all available detail on FHLBank bonds as they settle. Within the Daily Issuance Files, the Bonds link contains all settlements from a given day. The Daily Changes files show all bonds with a servicing event occurring, such as a interest rate reset or reduction of principal. The Full File, which is updated every Friday morning, contains all outstanding FHLBank bonds (in the Bonds link). The additional links appearing under all three (Daily Issuance, Daily Changes and Full File) supplement the Bonds link with the additional detail shown below. The Cusip number is the common data field in all files, allowing them to be used like database tables.
