How this is measured

The 30-year par yield is the coupon rate at which a new 30-year Treasury security would sell at par, from the curve Treasury fits each business day to closing bid prices. Month-ends are the last business day of each finished month Treasury published a value for this term; the running month shows in the last 30 days. The 52-week range and the changes in basis points are computed by 500metrics.

What this number cannot tell you
  • A fitted curve value, not the yield of one security: an outstanding note or bond of about this term trades at its own yield.
  • Month-end values hide moves inside the month; the last 30 days are shown day by day.
