The bond market is warning that trouble could be on the horizon, either from an economic slowdown or an eventual recession.
The yield curve, a set of interest rates watched closely by bond market pros, has gotten to its flattest level since before the financial crisis. The spread between 2-year note yields and 10-year yields this week reached near the lows, at about 0.75, it has been since before the financial crisis.
"It certainly is giving you some sort of signal in here. The signals are when the yield curve flattens, it tells you that inflation is not a problem and the Fed is doing something at the front end," said David Ader, Informa Financial Intelligence chief macro strategist. "Historically, it signals a slowdown or recession."
But with the Federal Reserve set to raise interest rates in December, and uncertainty about who the next Fed chief will be, there are also other concerns in the market, including that a new Fed head could be more hawkish and set the Fed on a more rapid rate-hiking course.
"It's also telling you there could be a policy error in the Fed's hiking particularly if they accelerate it," said Ader. Bank of America Merrill Lynch's monthly fund manager survey showed that fund managers in October believe the biggest risk for markets is a central bank policy misstep.
