Treasury HQM corporate bond yield curve

The U.S. Treasury High Quality Market (HQM) corporate bond yield curve — monthly average spot rates, as decimals, carried here at maturities from 0.5 to 30 years. The §430 segment rates are derived from Treasury's monthly corporate bond yield curve; the curve Treas. Reg. §1.430(h)(2)-1(d)(1)(i) defines runs at 6-month durations from 6 months through 100 years, so this table is not the whole of the §430(h)(2)(D)(ii) yield curve.
