How it is measured
The annualized return on a thirty-year loan to the US government, the longest point on the Treasury's daily par yield curve. At this horizon the yield is mostly a bet on decades of inflation and growth rather than on any particular Fed meeting. The data reaches us through FRED, the Federal Reserve Bank of St. Louis's data service, and originates with the US Treasury's daily par yield curve.
What the curve shows
The window runs from 1.27 percent (April 2020) to 14.68 percent (October 1981). The long bond anchors pension liabilities and the 30-year mortgage market, which is why insurers and pension funds are its natural buyers.
