A Guide to Bonds
A bond is a type of debt security where an investor lends money to an entity (typically corporate or governmental) for a set period at a fixed interest rate. In return, the bond issuer promises to pay back the principal (the amount borrowed) at the bond's defined maturity date, along with periodic interest payments, known as coupon payments.
Purpose and usage: Bonds are used by governments, municipalities, and companies to finance projects, fund operations, or refinance existing debt. They are an alternative to raising money through equity (selling shares), and bondholders are considered creditors, unlike shareholders, who own part of the company. For investors, bonds are a way to earn fixed income with less risk compared to stocks, as they often provide regular, predictable returns.
Types of Bonds
- Corporate Bonds: These are issued by companies to raise capital for various purposes. They tend to offer higher interest rates (also know as yields) compared to government bonds because they usually carry more risk.
- Sovereign Bonds: These are issued by national governments. They are often considered low-risk, especially when issued by stable countries, since they are backed by the government's ability to raise taxes and control currency. Sovereign bonds are a popular investment for risk-averse investors seeking stability.
Bond Riskiness
Rating agencies and their function: Credit rating agencies like Moody's, Standard & Poor's (S&P), and Fitch, assess the creditworthiness of bond issuers. They evaluate the issuer’s financial health, stability, and ability to meet debt obligations. The agencies assign a rating (from AAA to D, AAA being the best) that reflects the likelihood of default. These ratings help investors make informed decisions about the risk associated with different bonds. A change in rating can impact a lot the price of a bond, because certain financial institutions like pension funds, are required to only hold highly rated bonds in their portfolio, causing them to sometimes sell bonds that see their grade lowered.
Bonds are usually divided in 2 categories based on their riskiness:
- Investment-grade bonds: These have a high probability of repayment and are less risky. They are rated "BBB" or higher by major credit rating agencies (e.g., Moody's, S&P, Fitch). They typically offer lower yields because they are considered safer.
- Junk Bonds: Also known as high-yield bonds, junk bonds are issued by companies or governments with lower credit ratings (below "BBB"). These bonds carry a higher risk of default but offer higher yields to compensate investors for the added risk.
Bond prices factors
There is an inverse relationship between interest rates and bond prices. When interest rates rise, existing bond prices fall. This is because newer bonds issued at higher rates are more attractive to investors, making older bonds (with lower interest rates) less desirable. Conversely, when interest rates fall, existing bond prices rise, as their higher yields become more attractive relative to newly issued bonds with lower rates.
Bond Yield: The yield of a bond is the return an investor expects to earn if the bond is held until maturity. Yield is calculated by dividing the bond’s annual interest payment by its current market price.
As bond prices fall (due to rising interest rates), the yield increases because the fixed interest payments now represent a larger percentage of the lower bond price. Similarly, when bond prices rise (due to falling interest rates), the yield decreases.
The yield curve
The yield curve is a graph that plots the interest rates of bonds having equal credit quality but differing maturity dates. The x-axis represents time to maturity, and the y-axis represents yield.
The yield curve is closely watched by investors and policy makers because it indicates expectations about future economic conditions and interest rates.
Types of Yield Curves:
1. Normal Yield Curve: In a normal yield curve, longer-term bonds have higher yields than short-term bonds. This occurs because investors demand more compensation for tying up their money over a longer period due to risks like inflation or uncertainty about future interest rates. A normal yield curve indicates a healthy, growing economy.
2. Inverted Yield Curve: An inverted yield curve occurs when short-term yields are higher than long-term yields. This often signals investor expectations of declining interest rates in the future, possibly due to an economic slowdown or recession that would lead the central bank to lower interest rate, in order to increase lending and thus stimulate economic activity. Historically, an inverted yield curve has been a reliable indicator of an impending recession.
3. Flat Yield Curve: A flat yield curve occurs when short- and long-term yields are very close to each other. This situation can indicate uncertainty about future economic conditions. It may suggest a transition between normal and inverted yield curves, often signaling an economic slowdown.
