Understanding the relationship between inflation, interest rates, and bonds
Investing in bonds can enhance your investment portfolio through two primary ways: the interest payments bonds offer and potential increases in their prices.
While the appeal of bonds often lies in their ability to provide a stable income stream, bond prices can exhibit fluctuations akin to any tradable security, such as shares or indices, once available to the secondary market. Investors can therefore buy or sell bonds before they reach their maturity date!
If you want to make the most of bond investing, understanding the behavior of bonds and the factors that influence them is essential, particularly concerning their intricate connection to inflation and interest rates. Let’s focus on the relationship between inflation, interest rates and bonds in this article.
Bond prices, coupon and yield - Understanding bonds basics
When a company, city, or country needs money to finance its projects, it can acquire funds through borrowing from a bank, conducting an initial public offering (IPO), or issuing bonds, depending on the available options.
Bonds represent debt securities that are issued with interest payments paid regularly to investors until the bond reaches maturity, at which point the principal is returned to investors. This characteristic ensures a consistent income stream for bondholders over time, thus earning them the moniker of fixed-income financial products.
The money received by bond investors is referred to as a coupon, and its value is significantly influenced by the prevailing interest rate environment at the time of bond issuance. Furthermore, this coupon remains unchanged throughout the life of the bond, up until maturity (unless the investment involves floating-rate or variable-rate bonds).
This is where inflation expectations come into play. However, before delving into further details, let's get into the mechanics of bond pricing.
As previously explained, a bond's coupon rate is typically fixed, while its yield—which signifies the rate of return on your bond investment at any given point—fluctuates over time based on the interaction between the coupon rate and changes in the associated bond's price.
To calculate the yield of your bond investment, simply divide its coupon by the face value of the bond.
It's important to note two key concepts. Firstly, market conditions, especially alterations in the trajectory of monetary policy and interest rates, significantly impact a bond's price. An existing bond may become more or less appealing to investors in comparison, thereby inevitably affecting its value.
Secondly, bond prices and yields exhibit inverse movements. In other words, when a bond's price rises, its yield decreases, and when its price falls, its yield rises.
Let's consider a simple example.
Imagine you've invested $1,000 in a bond with a 2% coupon. Consequently, you would receive $20 annually. At that time, the yield of your bond is 2% ($20/$1,000). However, if the bond's price subsequently drops to $500, the coupon amount remains at $20 per year, but the yield changes. It escalates to 4% ($20/$500).
Why are inflation levels and inflation expectations so important in bond pricing?
Current inflation and inflation expectations greatly affect bond prices, making them important for bondholders. But how do they impact bond values?
The first thing to remember is that when there is inflation, the overall higher prices faced by investors mean that the purchasing power of the coupon decreases. Therefore, it tends to push the price of bonds lower, as bondholders are afraid that a bond's yield won't keep up with the rising costs linked to inflation. Thus, the demand is usually lower, leading to a drop in bond prices.
The second thing to take into account is the response of central bankers to high inflation. After credit risk, interest rate risk is the second primary risk you need to be aware of when investing in bonds.
If inflation is too high - relatively high for too long or out of control - central bankers are likely to decide to increase their main interest rates to slow down consumption in an attempt to cool inflation, which is similar to what we're currently seeing in most developed countries today. Borrowing money becomes more expensive.
When interest rates go up, the demand for existing bonds decreases because newly issued bonds offer higher interest income, and older bonds are less valuable. This means that their yields go up,while the coupon remains the same.
Of course, changes in the prevailing inflation and interest rate environment do not affect all bonds in the same way. The maturity of a bond plays an important role.
Overall, short-term interest rates will change immediately depending on the given central bank's announcements, as they are controlled by officials. However, bonds with longer maturity are likely to experience the largest price changes. While central bankers do not directly control them, their decisions still impact longer rates.
This is primarily because the risk is more significant (it is harder to make projections regarding market developments so far in the future), and the duration is greater (the bond’s price sensitivity to changes in interest rates).
Should you invest in bonds when interest rates are rising?
Over the last 15 years, we have witnessed historically low interest rates or even negative interest rates in some countries. Therefore, for numerous investors, the rising interest rates environment we’re currently experiencing marks a new era and it’s important to understand how this rise in rates can impact your portfolio in the coming months and years.
As interest rates increase, new bonds tend to offer more attractive yields. If you're thinking about investing in bonds when rates are on the rise, you can take advantage of securing these elevated yields. This has the potential to enhance your income flow throughout the bond's lifespan.
Keep in mind the timeframe you're aiming for in your investments. If your intention is to retain the bonds until they mature, the influence of fluctuating bond prices due to shifts in interest rates may hold less significance. As planned, you'll continue to receive regular coupon payments, and your principal will be returned upon maturity.
Bonds holders: Here are the mistakes to avoid!
Insufficient comprehension of how bonds operate can result in unwise investment decisions due to misunderstandings about their functioning within the financial landscape. Moreover, neglecting the process of meticulously selecting bonds in line with your risk tolerance and financial objectives can undermine your investments.
While credit ratings are a significant gauge of bond quality, relying solely on them can pose challenges. It's important to recognize that credit ratings may not encompass all potential risks associated with a specific bond.
Bonds encompass a range of risks beyond the possibility of the issuer defaulting. Considerations such as market fluctuations, liquidity challenges, and shifts in interest rates should be carefully weighed when assessing potential investments.
Believing that bonds are entirely devoid of risk is a misconception. It's crucial to acknowledge that all investments inherently carry some level of risk, including bonds. Disregarding this reality can lead to misguided choices and unforeseen financial complications.
As mentioned before, changes in interest rates have a big impact on bond prices. Disregarding these changes can result in missed opportunities or unanticipated losses, so keep a close eye on monetary policy decisions!
Keep in mind that you are not obligated to hold onto your bonds until they reach maturity. Bonds can be priced in three ways: at a discount, at par, or at a premium.
When a bond is priced above par (meaning the yield-to-maturity is greater than the bond's face value), it's referred to as a premium bond. This indicates that the bond's coupon rate is higher than the prevailing interest rate. In such cases, selling the bond might be a compelling option for you. Naturally, it's crucial to consider additional factors and take the broader context into consideration before making any decisions.
