The Thirty-Year Verdict
An interactive, 18-minute guide to how Treasury auctions set bond prices—and why that can make mortgages more expensive even after Federal Reserve rate cuts.
Field notes
The explainer advances through named acts, beginning with the distinction between the Fed's overnight rate and the longer-term Treasury market. Its worked example gives readers a $1,000 bond with a 4% coupon and 30-year maturity, while a chart uses monthly Federal Reserve and US Treasury figures to mark the late-2024 crossover. The page also flags that its annual-coupon arithmetic simplifies real Treasuries, which pay every six months.
