Five spots to watch as the bond market creeps up on 5%
SPY•The yield-to-growth backdrop and real rates
The relationship between the 10-year Treasury yield and nominal U.S. economic growth has perhaps been overlooked during the bond selloff. But analysts who track this ratio aren't especially concerned.
The benchmark yield touched 4.8% on Friday and earlier in the week hit its highest since October 2023. But nominal year-on-year GDP growth for the first quarter was at 6.07% and rose to 6.56% in the second quarter, keeping borrowing costs below the economy's growth rate.
Economists say that growth cushion lets Washington expand deficits without the debt burden spiraling out of control.
That could change if the arithmetic flips. When Treasury yields exceed growth, debt becomes increasingly heavy to sustain as interest costs compound faster than revenue. With yields rising and deficits wide, analysts say the margin for error is narrowing.
