Why Treasury yields are stuck high — and what changes when they move

If you've shopped for a mortgage, looked at CD rates, or watched bond prices in your retirement account, you've felt the effect of stubbornly high Treasury yields. Even with the Fed having cut its short-term policy rate from peak levels, longer-term Treasury yields have remained elevated. There are real reasons.

What's keeping long yields high

• Federal deficits — the U.S. government is borrowing heavily to fund its spending, increasing the supply of Treasury bonds. More supply tends to push yields up (and prices down).
• Inflation expectations — bond investors demand higher yields when they expect inflation to erode their future interest payments.
• Foreign demand — historically large buyers like China and Japan have reduced their U.S. Treasury purchases, removing some of the buying pressure that used to keep yields lower.
• Term premium — investors are demanding more compensation for the risk of locking up their money in long-term bonds, after several years of unpredictable rate moves.

What this means for everyday financial mechanics

• Cash savings: high-yield savings accounts and Treasury bills have continued to offer real (above-inflation) returns. The trade-off between locking in a rate vs. staying flexible depends on a person's view on whether rates will fall.
• Mortgages: 30-year mortgage rates closely track 10-year Treasury yields. Mortgage costs tend to stay elevated until those Treasury yields come down.
• Bond fund prices: when yields rise, the prices of existing bond funds fall — that's the price-yield relationship working as designed. The forward yield those funds will deliver has actually improved.
• Stock valuations: when a Treasury bill earns 4-5% 'risk-free,' stocks need to deliver more to compensate for the additional volatility. High-rate environments typically pressure stock valuations.
