Riding the yield curve in up and down markets

Curved Bridge
Through active management, institutional investors in municipal bonds can employ professional strategies that seek to overcome market complexities and take advantage of profitable opportunities. One such strategy, which may be difficult for individual investors to implement due to transaction costs, is called “riding the yield curve.”

Returns may be enhanced by selling a bond at its peak price and rolling into a longer maturity bond. Two principles make this strategy viable:

  1. Bonds with longer maturities typically have higher yields to compensate investors for a longer period of uncertainty.
  2. Bonds with higher yields have lower prices, assuming coupon rates and maturity remain the same.

The yield curve


The first principle can be visualized by plotting a yield curve. If one charts yields on the Y-axis, and time to maturity on the X-axis, the resulting line will slope upward to the right, as shown in Exhibit 1.

 

The yield curve

The price of a bond


The second principle implies that the price of a bond will, for a time, rise as it approaches maturity because it will be priced to progressively lower yields. At some point, however, the price will start to decline because the need to eliminate the premium over shorter and shorter periods outweighs the effect of pricing to lower yields.

If a bond with a 2.50% coupon is priced to yield 2.00% (as a result, for example, of a change in interest rates or because the bond is now being priced to a shorter maturity), the bond will be priced above par. The difference between the coupon rate and the yield (in this case 0.50%) will be roughly the amount by which the premium declines each year.

Thus, if the bond has four years until maturity, the dollar price will be about 102. But if the same bond has only two years to maturity, the dollar price will be about 101, since, at 0.50% per year, the one point premium will be fully amortized in two years. For the price to stay at 102 with two years until maturity, the yield would have to fall to 1.50%, which would be 1.00% lower than the coupon rate so that about 1.00% of premium would be amortized each year. Assuming that the yield curve remains unchanged, Exhibit 2 shows how the price of a bond changes over time simply as a result of rolling down the yield curve.

 

Price of non call
Portfolio managers may derive increased value by selling bonds with just a few years to maturity while their prices are still high. That generates more proceeds that can be reinvested into bonds with longer maturities and higher yields. The amount of benefit from this strategy depends on the slope of the yield curve and the timing of purchases and sales.

Illustration: how it works


Suppose that on 30 Apr 2019, the AAA rated, non-callable yield curve was as follows:

Total return annualised vs beta 15 year.

Further suppose that someone invests $100,000 in a bond with the following characteristics:

 

Maturity how

Ten years later, on 30 Apr 2029 if interest rates remain the same throughout the yield curve, the investor could sell that bond at a dollar price of $103.732 based on the fact that bonds with 5 years to maturity are priced to yield 1.62%. The proceeds of that sale could be used to purchase the new bond shown below.

 

Maturity future

By selling the original bond for more than par, the investor would be able to buy a premium bond with a higher coupon. Finally, in the year 2034 (15 years after the original investment and five years after the swap) the new bond has a dollar price of $107.353 (priced to yield 1.88% to maturity in 10 years). To summarize, below is the way the investor’s cash flows look:

 

Invest cash flow

Using these cash flows, we can compute the internal rate of return (IRR) on this investment, which is the interest rate that causes the present value of the amounts received to equal the amount invested. The IRR in this case is 2.88%. If the investor just held the original bond until it matured, the IRR would have been 2.40%, which is the yield at which the bond was purchased. Thus, by selling the bond with 5 years remaining to maturity and reinvesting in another 15-year bond, the investor increases the return by 0.48%.

 

Rate return constant

What happens if interest rates fall?


Suppose, in our example, interest rates had fallen 0.50% sometime in the first 10 years after the bond was purchased and remained there for the remainder of the 15-year period. (Since the coupon stream remains constant until the bond is sold in year 10, all that matters is what the yield curve looks like in the last 5 years.) In 2029, the original bond would be worth $106.207 as it is priced to yield 1.12% (0.50% less than in the original scenario). This amount would be reinvested as follows:

 

Rate return fall

In 2034, the new bond would be priced to yield 1.38%, producing a price of $109.311. The cash flows would be:

Invest rate fall

 

Rate return file

What happens if interest rates rise?


We obtain similar results if we assume that yields rose by 0.50%. In that case, the original bond would be worth $101.322 after 10 years (priced in 2029 to yield 2.12% to maturity in 2034). The 0.50% increase in interest rates means that a new 15-year bond would yield 2.90%. Because the investor had more than $100,000 to spend, the new bond would be worth more than par, and would have a coupon rate of 3.01%, which is greater than its yield.

 

Maturity rise

In 2034 the new bond would be worth $105,577 if priced to yield 2.38% to its maturity in 10 years. Here are the cash flows:

 

Invest flow rise

 

Internal rate of return if interest rates rise 0.5%

Explanation: why it works


At first glance, this strategy sounds like the proverbial “free lunch,” but it has a logical explanation. If the investor were to hold the bond to maturity, the investor would have a security whose yield decreases over time. This lower yield reflects the fact that the price volatility of the bond, in other words, its market risk, would also be decreasing.

The principle in operation here is that the maturity of a bond affects how much the price changes in response to changing interest rates: the shorter the maturity, the less the change. By swapping into a longer bond in the tenth year, the investor replaces a lower yielding security with a higher yielding security. This higher yield compensates for the fact that the new bond has greater price volatility.

This trade, however, merely restores the volatility to the level of risk originally chosen by the investor. The investor substantially improves his return by taking advantage of the market’s preference for low volatility and by making judicious use of the shape of the yield curve in selecting maturities for sale and purchase.

Conclusion


By monitoring the shape of the yield curve and capturing the value produced when bonds ride the yield curve, portfolio managers can enhance the returns that investors receive from their portfolios in up and down markets.

 

Conclusion yield

Assumptions**

The preceding analysis is based on two assumptions. The first is that the yield curve retains its current slope. If the yield curve were steeper, the benefits of selling, in 2029, a bond due in 2034 and replacing it with a bond due in 2044 would be enhanced. On the other hand, a flatter yield curve would reduce the benefit of this strategy.

The slope of the current callable municipal yield curve is flatter than it has been in recent years. As of 30 April 2019, the spread of 15-year yields over 5-year yields was 0.56% (2.19% - 1.63%), which is less than the average spread of 1.42% over the last 10 years.

The second assumption is that interest rates do not increase between 2029 and 2034. By the year 2034, the investor in the example would be holding a bond with 10 years remaining to maturity, while an investor who continued to hold the original bond would then be receiving the principal balance in cash. If rates on 10-year bonds increased between 2029 and 2034, the investor would, in many cases, be better off holding cash at the end of the period than holding a 10-year bond (depending on how high 10-year yields became).

On the other hand, if rates fell, the investor with a 10-year bond would enjoy appreciation not available to the investor who receives a return of principal in 2034. Since these risks are symmetrical, and their impact varies with the interest rate cycle, we believe the effect of changes in rates should average out if the strategy of riding the yield curve is consistently followed over time.

The effect of rate changes should average out if the strategy is consistently followed over time.

A word on risk

This strategy focuses primarily on the impact of changes in interest rates. However, it is important to remember that an investment in municipal bonds is subject to market risk, credit risk, interest rate risk and the possible loss of principal. The value of the portfolio will fluctuate based on the value of the underlying securities.

This information should not replace an investor’s consultation with a professional advisor regarding their tax situation. Nuveen Asset Management is not a tax advisor. Investors should contact a tax advisor regarding the suitability of tax-exempt investments in their portfolio. If sold prior to maturity, municipal securities are subject to gain/losses based on the level of interest rates, market conditions and the credit quality of the issuer. Income may be subject to the alternative minimum tax (AMT) and/or state and local taxes, based on the state of residence. Income from municipal bonds held by a portfolio could be declared taxable because of unfavourable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. It is important to review your investment objectives, risk tolerance and liquidity needs before choosing an investment style or manager.
