"A normal yield curve
slopes upward, demonstrating the additional yield investors typically demand in exchange for a longer maturity date," Fossier said."When interest rates for bonds with a longer maturity trade at a lower yield than bonds of a shorter maturity, the relationship is said to be inverted."
