Bond yields are surging again, and that movement reaches far beyond Wall Street. The 10-year Treasury yield climbed above 5% on September 15, reaching about 5.04%, its highest level since 2007, as investors reacted to inflation concerns, higher oil prices and worries about government borrowing.

That matters because Treasury yields help set the tone for many other interest rates. A rising yield can create opportunities for savers while making life more expensive for borrowers, and it can even shake up what happens inside a 401(k). The financial world loves complicated vocabulary, but the basic idea is surprisingly simple: when the bond market moves, household money can feel the ripple.
