An inverted yield curve, which has historically predicted nine out of ten recessions since 1955, is a potential signal of a coming recession, although the current yield curve is described as flattened rather than inverted.
"it's predicted nine of the recessions that have happened since 1955 in the year 2021 the yield curve flattened and and now we're expecting that the recovery is going to be slower and we're expecting inflation to be higher so investors are pessimistic which is why that curve is kind of flattened and some people are worried that if we inflect to the negative downward so it inverts that that could signal to investors again that another recession is coming"
