What is a 'Benchmark Bond'
A benchmark bond is a bond that provides a standard against which the performance of other bonds can be measured. Government bonds are almost always used as benchmark bonds. Also referred to as "benchmark issue" or "bellwether issue".
BREAKING DOWN 'Benchmark Bond'
More specifically, the benchmark is the latest issue within a given maturity. For a comparison to be appropriate and useful, the benchmark and the bond being measured against it should have a comparable liquidity, issue size and coupon.
