US 30-year Treasury yield chart
The US 30-year Treasury yield is the constant-maturity interest rate on a US government bond with thirty years remaining to maturity, expressed as a percentage per annum. Known as the 'long bond', it is the furthest point on the standard Treasury curve and is particularly sensitive to long-run fiscal and inflation expectations.
This chart plots the daily 30-Year Treasury Constant Maturity Rate published by the Federal Reserve Board via FRED. It is an official statistical series derived from the US Treasury's daily par yield curve, not a tradable price feed.

What is US 30-year Treasury yield?
The 30-year yield is interpolated by the US Treasury from its daily par yield curve, representing the rate a hypothetical newly issued 30-year bond would carry that day given prices across the rest of the curve.
As with any bond yield, it moves inversely to the price of the corresponding bond, and because of its long duration the 30-year bond's price is especially sensitive to changes in this yield.
How to read this chart
A rising 30-year yield often reflects concerns about long-run fiscal sustainability, higher expected long-term inflation, or reduced demand from long-duration buyers such as pension funds and insurers; a falling yield reflects the opposite.
Because long-duration bonds are highly sensitive to yield changes, a given move in the 30-year yield produces a larger price swing than the same move at the 2-year or 10-year point.
The series is updated once per business day; multi-day trends are generally more informative than single-day moves for a maturity this long.
What moves it?
- Pension and insurance demand
- Long-duration institutional buyers such as pension funds and life insurers use 30-year bonds to match long-dated liabilities, and shifts in their demand can move the yield independently of near-term policy.
- Fiscal outlook
- Expectations about the scale of future government borrowing and debt sustainability weigh on the term premium demanded for very long-dated debt.
- Long-run inflation expectations
- Because the bond pays a fixed nominal coupon for thirty years, expected average inflation over that horizon is a major component of the yield.
- Treasury issuance patterns
- Changes in how much long-dated debt the Treasury chooses to issue relative to shorter maturities affect the supply investors must absorb at this point on the curve.
- Global long-duration demand
- Foreign institutional and reserve demand for very long-dated, high-quality debt also affects pricing at the long end.
Why businesses and investors monitor it
The 30-year yield is a reference point for long-dated corporate bonds, some fixed-rate mortgage products, and actuarial discount rates used in pension and insurance liability valuation.
Businesses with very long planning horizons — infrastructure, utilities, insurance — use it to gauge the cost of long-term capital and the direction of long-run fiscal and inflation expectations.
US 30-year yield vs US 10-year yield
Both are long-dated points on the Treasury curve, but the 30-year yield carries additional term premium and duration risk and is more directly influenced by pension and insurance demand and by long-run fiscal considerations.
The 30Y–10Y relationship is used to gauge whether investors are demanding extra compensation specifically for the furthest end of the curve, separate from the broader growth and inflation outlook reflected across both maturities.
Frequently asked questions
Why is the 30-year yield more volatile in price terms than shorter yields?
Longer-duration bonds are more sensitive to a given change in yield, so the same yield move produces a larger price swing on a 30-year bond than on a 2-year or 10-year note.
What is the 'long bond'?
It is a common market nickname for the 30-year Treasury bond, reflecting its position as the longest standard maturity issued by the US Treasury.
Does the 30-year yield reflect Fed policy directly?
Only loosely. It is more influenced by long-run inflation expectations, fiscal outlook and long-duration investor demand than by the Fed's near-term policy rate.
Is this the same as a 30-year fixed mortgage rate?
No, but many long-term fixed mortgage products are priced with reference to long-dated Treasury yields plus a spread reflecting credit and prepayment risk.
