Why the bond market is flexing its muscles, and why everyone needs to care

NEW YORK (AP) — The bond market is one of the few forces in the world strong enough to get politicians to snap to attention. It also helps 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. This week rising bond yields forced the U.S. Treasury Department into an unusual intervention and raised the specter of higher borrowing costs putting the brakes on consumer spending, the lifeblood of the economy. It also sparked concerns that investors might finally be thinking twice about financing a seemingly endless flow of government borrowing.
