10Y 5.17%
A fitted curve puts each maturity where a model says it belongs.
The Board's fitted zero curve on 25 Sep 2026, from six Svensson parameters: 5y5y at 5.45% and 10y10y at 6.13%.
The par yield curve across every Treasury maturity, from 1-month bills to 30-year bonds: what people mean by the Treasury yield curve.
A fitted curve puts each maturity where a model says it belongs. What decides that is what every seasoned bond on the market costs, and the distance to a published yield runs either way.
Read a point as the yield the fit says that maturity should pay; what matters is the distance to Treasury’s published dot.
It shadows Treasury’s almost everywhere. Where the two part company, at ten and thirty years, sits the benchmark premium.
A fitted 10Y of 4.34% against a published 4.30% leaves the benchmark 4bp rich.
Svensson’s six parameters, fitted by Gürkaynak, Sack and Wright on seasoned bonds only. It is staff research, revised without notice, and lags a week or two, so what it draws is never today.
