Treasury Prices and Yields Move in Opposite Directions

For an existing fixed-rate Treasury security, a higher market yield requires a lower price and a lower market yield requires a higher price, all else equal.

What it is

A fixed-rate note or bond promises contractual cash flows. When the market return required on comparable cash flows changes, the security’s price adjusts so its yield reflects the new market environment.

Why it matters

This inverse relationship is basic to interpreting Treasury-market headlines: a yield rise is not a price rise, and a bond selloff is normally associated with higher yields.

Example

If newly available market yields rise above the coupon on an existing fixed-rate Treasury, that older security generally must trade below par to offer a competitive yield.

Common mistake

Reading a higher Treasury yield as evidence that the price of the same fixed-rate Treasury also increased.

What to watch

Key takeaway

For existing fixed-rate Treasuries, price and yield move in opposite directions.
