From the Washington Post:
"A decade of historically low interest rates has allowed companies to sell record amounts of bonds to investors, sending total U.S. corporate debt to nearly $10 trillion, or a record 47 percent of the overall economy.
In recent weeks, the Federal Reserve, the International Monetary Fund and major institutional investors such as BlackRock and American Funds all have sounded the alarm about the mounting corporate obligations.
The danger isn’t immediate. But some regulators and investors say the borrowing has gone on too long and could send financial markets plunging when the next recession hits, dealing the real economy a blow at a time when it already would be wobbling."Bottoms Up
