Why bond yields are rising and why everyone should care

WASHINGTON (AP) — Interest rates on government bonds are rising again around the world, making borrowing more expensive for consumers and businesses and heightening concerns about whether governments are issuing more debt than financial markets can handle. Rising bond yields are one of the few forces in the world strong enough to get politicians to snap to attention. They can also have a big impact on Americans' personal finances and on the broader economy. The bond market can dictate how much ordinary people have to pay on their mortgages and car loans, as well as how much they earn from their savings accounts and 401(k) plans. Fighting has flared up again in the Middle East, causing oil prices to jump and renewing inflation worries. Investors typically demand higher interest rates, or yields, on government bonds when inflation is high or they think it may get worse. On Tuesday, the yield on the 10-year Treasury, which strongly influences mortgage rates, reached 4.80%, the highest since early 2025. The 5-year Treasury, which is a benchmark for auto loans, touched its highest level since October 2025 at 4.55%.
