Yield Curve Inversion: Bond Market Sends Up a Recession Warning Signal
An inverted yield curve does not always foreshadow a recession, however. Intraday inversions that quickly correct to the normal relationship have often been misleading signals.
The yield curve may also have lost some of its predictive power. Very large budget deficits have increased the amount of bonds the government is selling. The government’s choices about which bonds to sell could cause an over-supply or under-supply in some parts of the yield curve, which in turn could invert the curve.
The 'Federal Reserve’s actions as it shrinks its balance sheet, inflated from years of bond buying under the central bank’s quantitative easing program, may also be putting pressure on the curve. This is largely an unprecedented event so its effects are hard to predict and likely will not be known for years.
