Definitions for "bond market"
The market in which instruments of fixed-income debt are issued and traded....
The market for all types of bonds, whether on an exchange or over-the-counter. Lenders follow the bond market intensely because as the yields of bonds go up and down, fixed rate mortgages will just about do the same thing. The same factors that affect the Treasury Bond market also affect mortgage rates at the same time and therefore, rates change throughout the day.
A market in which bonds issued by firms or governments are traded. (p. 385)
