There's a trend underway in the market and Cramer doesn't like it.
The trend is negative because it suggests money is rotating out of stocks that do well in an economic recovery and into stocks that do well in a slowdown.
To make the situation all the more troubling, the bond market has rallied significantly in recent days. "The gain in prices and decline in yield suggests demand for money has dropped off a cliff," Cramer said.
"The 10- year Treasury is now under 2.5%. It was about to break above 3% percent not that long ago. You simply don't get this kind of move in interest rates unless something's gone awry."
Largely the Mad Money host worries that the price action in the stock market and bond market are two signs that the global economy is about to stumble.
