The most accurate sign of a coming recession is not what you think it is - and it's on the verge of flashing

• The inverted yield curve is a closely followed recession indicator, but it isn't the only one to watch.
• Prior inversions have preceded a recession by as much as two years, making it difficult to use as an accurate gauge.
• It's the re-steepening of the yield curve, or de-inversion, that's more closely followed by a recession. 

Investors love to point to an inverted yield curve as a surefire signal that the economy is about to hit a recession.
