Yield Curve


Yield Curve is a graph that depicts the relationship between bond yields and maturities. It is a reliable leading indicator of economic activity and a useful tool in fixed-income investing. The Yield Curve graph displays the bond’s yield on the vertical axis and the time to maturity across the horizontal axis. The plotted line begins with the spot interest rate, which is the rate for the shortest maturity, and extends out in time, typically to 30 years. In the different stages of the economic cycle, the curve takes different shapes at different points.


The yield of short-term bonds is greatly influenced by central bankers as they increase liquidity in an attempt to stimulate the economy. For long-term bonds such as 10-year and 30-year bonds, their price is usually dictated by the market forces whereas traders usually price these longer-term bonds based on the expected inflation rate.

 

Types of Yield Curve

Normal Yield Curve

 


This is the most common shape for the curve, also referred to as the normal curve. The yield curve slopes upward, reflecting that bond yields increase as maturity extends. For instance, lower interest rates for 3-month bonds, and higher interest rates for 30-year bonds. Under this circumstance, the market and economy are considered good as short-term money supply stick with low short-term interest rates, and the long-term interest rates are reasonable and affordable from the market.

 

 


Compare to the normal yield curve, the yield curve will look like when a higher inflation rate is expected. This will cause the long-term interest rates to increase. This is beneficial for banks as banks borrow money at short-term rates, either from the federal banks or their depositors, and turn around to lend the money to borrowers for a longer period at higher rates, boosting their net interest margin. However, it doesn't mean the higher the long-term interest rate, the better for banks.

An extraordinarily high-interest rate will deter borrowers from borrowing and a higher interest rate also increases the burden of borrowers, hence increasing the risk of loans being defaulted. 



A yield curve turns flattish when the short-term interest rates move up more than the long-term interest rates. This usually happens when the central bank is reducing the money supply, followed by a tighter liquidity situation. When the yield curve turns flat, it usually implies that the market liquidity is drying up and the capital market is going to retrace soon.



When the short-term interest rates remain but long-term interest rates decrease, a yield curve like "C" is formed. The long-term interest rate decrease when traders expect the long-term inflation rate to remain low for a prolonged period. A low inflation rate environment also hints that the economic situation is weak, making business owners reconsider their long-term investment plan, which eventually leads to a decrease in demand for long-term funds.

When long-dated interest rate is low, tech stocks with light balance sheets are favored while value stock, companies who require massive capital expenditure to generate their revenue are shunned. A downward push in the long-term interest rate also compresses the bank's margin. 


Inverted Yield Curve


The inverted yield curve is sloped downward, with short-term yields higher than long-term yields. It suggests that investors expect interest rates to decline in the future, usually in conjunction with a slowing economy and lower inflation.



Factors affecting Yield Curve

Expectations of Interest Rates

When the market expects interest rates to rise, market participants will purchase short-term bonds instead of long-term bonds. Investors take this action in the anticipation that they can purchase high-interest-rate bonds once their short-term bonds have matured.

In short, long-term bonds are more sensitive to interest rates changes as they are a greater duration and exposed to the fluctuation of interest rates.

 

Changes in Supply of Bonds

The supply of bonds depends on how much the bond’s issuer is required to borrow the money from the market. When the supply of short-term bond increase, all else equal the bond price will fall and yield rise, vice versa. For example, the government decides to rise the issuance of 10-year bonds, the supply of the bond price fall, causing the yield to increase and so steepens the yield curve.

 

 

Changes in Demand for Bonds

Banks and corporations need liquidity and invest in short-term bonds, while life insurance and real estate companies invest in long-term bonds to match their long-term liabilities and project cycles. Assumes majority of participants invest money in the insurance companies, the demand for long-term bonds will increase as insurance company required to match their project cycles. All else equal, the bond price will rise and the yield will fall, vice versa.
