Federal Reserve Tampering with Interest Rates Distorts the Shape of the Yield Curve

For many commentators, a change in the shape of the differential between the long-term interest rate and the short-term interest rate—i.e., the yield spread provides an indication of the likely direction of the economy in the months ahead. Thus, an increase in the yield spread raises the likelihood of a possible strengthening in economic activity in the months to come. Conversely, a decline in the yield spread is seen as indicative of a possible economic downturn ahead.
