Typically, short-term interest rates are lower than long-term rates, so the yield curve slopes upwards, reflecting higher yields for longer-term investments. This is referred to as a normal yield curve. When the spread between short-term and long-term interest rates narrows, the yield curve begins to flatten. A flat yield curve is often seen during the transition from a normal yield curve to an inverted one.
