The yield curve is a specialized financial tool that is used to track the interest holding period rates % in comparison to various lengths of the maturity profiles.
Yield curves are generally plotted for T-bills and other govt debt securities and used to identify the required time to maturity and the Rate% to be offered for the desired time frame .
On plotting a line between these two profiles a smooth curve is obtained . This curve rises in steep at the beginning , then flattens and then again rises in the later part of the maturity profiles

 Description  |

 1  | 
 Normal yield curve  | 
 These yield curves are generally upward sloping yield curves . The points in the curves denote that as and when the time to maturity increase , the demand for the investors to get higher return also increases  | 
| 
 2  | 
 Flattened yield curve  | 
 The yield curve appears to be flattened over the span of years . Thus the issuer of the security isn’t willing to offer higher returns with increasing time frames Thus it denotes that the economy is unstable or in a phase transition is undergoing  | 
| 
 3  | 
 Inverted yield curve  | 
 This is a rather critical phase in the economy when the yield curve becomes flattened . This curve shows that the rates% decline as the maturity profile increases . This denotes that economy is declining and the rates are low as the holding period of the bond increases  | 
Yield curves provides the investors wit ha long term and holistic view in the economy . As such on allaying the yield curves the investor may decide on the timeline of investment and proportion of investment in fixed income based on the nature of the economy
