A 10-2 treasury spread that approaches 0 signifies a "flattening" yield curve. A negative 10-2 yield spread has historically been viewed as a precursor to a recessionary period. A negative 10-2 spread has predicted every recession from 1955 to 2018, but has occurred 6-24 months before the recession occurring, and is thus seen as a far-leading indicator. *
