After years of U.S. companies taking advantage of low interest rates to pile up cheap debt, Wall Street is beginning to take notice of a problem forming.

Corporate debt outstanding ended 2018 at just over $9 trillion, a 64 percent increase over a decade's time, according to the Securities Industry and Financial Markets Association. The surge came as the Federal Reserve kept its benchmark interest rate anchored near zero and allowed companies to reward shareholders, do deals and invest in their own operations.
