Bond with Bonds

By | TEDDY JOHN BEARE | What Are Financial Bonds? Understanding bonds: history, risks, and how to invest with them. As always, a quick note before we dive in: this is educational writing, not personalized financial advice, and I’m not a licensed advisor. Please consider your own situation, or speak with a professional, before putting real money to work. A bond is, at heart, an IOU with a schedule attached. When you buy one, you are lending money to an issuer, which might be a corporation, a city, a state, or a national government. In exchange, the issuer promises to pay you interest at set intervals and to hand back your original money on a specific date. That is the whole idea, and everything else in the bond world is a variation on this simple bargain. Three terms do most of the work. The principal, also called face value or par value, is the amount the issuer agrees to repay when the bond comes due. Many bonds are issued with a face value of $1,000. The coupon is the interest rate the issuer pays, expressed as a percentage of face value. A $1,000 bond with a 5 percent coupon pays $50 a year, usually split into two payments of $25. The maturity date is the day the bond expires and the principal comes back to you. Maturities range from a few weeks to thirty years or more. If you hold a bond until it matures, the cash flows are known from the day you buy it. That predictability is the reason bonds have a reputation for being the steady, sensible cousins of stocks. A stock gives you a slice of ownership and a share of whatever profits a company happens to earn. A bond gives you a contract. Bondholders sit ahead of shareholders in line if a company runs into trouble, which is one reason they typically accept lower returns in exchange for more reliable ones. Here is where bonds become more interesting than they first appear. Bonds can be bought and sold after they are issued, and their prices move. Imagine you own a bond paying 4 percent, and new bonds start paying 6 percent. Nobody will pay full price for your 4 percent bond when a 6 percent one is available, so its market price falls until its effective return becomes competitive. The reverse is also true: when new bonds pay less than yours, your older, richer bond becomes more valuable for redemption time.

That effective return has its own name: yield. Current yield compares the annual coupon to today’s price, while yield to maturity estimates your total annualized return if you buy at today’s price and hold to the end, counting both the coupon payments and any gain or loss between the purchase price and face value. When people say a bond “yields 4.5 percent,” they almost always mean yield to maturity. Bonds come in a wide family of types. Government bonds are backed by national treasuries. Municipal bonds fund schools, roads, and water systems, and their interest is often exempt from federal income tax. Corporate bonds finance everything from factory expansions to corporate takeovers, and they are graded by rating agencies from the sturdy “investment grade” tier down to the speculative “high yield” tier, sometimes called junk. Some bonds pay a fixed coupon for life, some float with a benchmark rate, and some, like zero-coupon bonds, pay nothing along the way and are sold at a deep discount to face value instead. Seen from above, the bond market is how the world borrows. Governments fund their budgets there, companies fund their growth there, and savers earn income there. It is a larger market than the stock market by most measures, and it quietly shapes the cost of mortgages, car loans, and business credit for nearly everyone. Borrowing with a promise to repay is older than coins. Clay tablets from ancient Mesopotamia record loans with fixed terms and interest, and scholars often point to these records as the ancestors of the modern debt contract. Rulers and merchants in Greece and Rome borrowed too, though these were private arrangements between a lender and a borrower rather than securities that strangers could trade. The bond as we know it took shape in medieval Italy. In the twelfth century, the city-state of Venice needed money to fight wars and forced its wealthier citizens to lend it funds, promising them interest in return. Those loans could be sold to other people, which made them something close to a tradable security until they are not redeemable.

Florence, Genoa, and other Italian cities followed, and a lively market in public debt grew up around them. Merchants in the Low Countries soon developed their own versions, and Amsterdam in the seventeenth century became a hub where debt and shares were bought and sold. The next great leap came in England in 1694. King William III was deep in an expensive war with France, and the Crown’s credit was shaky. A group of investors lent the government a large sum, and in return received a royal charter creating the Bank of England. This arrangement turned government borrowing into something more permanent: a standing national debt, funded by taxes and backed by the state’s promise to pay. Over the following century, British government bonds, known as consols, became a trusted asset held by investors across Europe. The idea that a nation could borrow cheaply because lenders trusted its ability to tax and repay was a quiet revolution. The United States leaned on bonds from its very birth. The Continental Congress raised money by selling loan certificates to fund the Revolutionary War, and in 1790 Treasury Secretary Alexander Hamilton convinced Congress to assume the states’ war debts and fund them with new federal bonds. His reasoning was that a government that honored its debts would earn lasting credibility, and that credibility would let the young country borrow cheaply for generations. The bet worked. In the nineteenth century, bonds also financed canals, and above all railroads, which were far too expensive for any single investor to build alone. The twentieth century brought bonds to ordinary households. During the First World War, the United States sold Liberty Bonds in huge public drives, backed by posters, parades, and appeals to patriotism. In the Second World War, war bonds were sold again, and millions of citizens bought them. For many families this was their first investment of any kind. Later decades produced the modern bond toolkit: municipal bonds for local projects, mortgage-backed securities had started in the 1970s, the high-yield market was in the1980s.

Bonds have also had their dramas. The 1970s saw inflation erode the value of long-term bonds, giving the asset class a bruising reputation. The following decades delivered the opposite, as interest rates drifted lower for roughly forty years and bond prices climbed. Then came 2022, when central banks raised rates sharply to fight inflation and many bond funds suffered some of their worst losses on record. Anyone who thought bonds could only be boring got a vivid correction. Today, bonds trade electronically as well as through dealers, and the global bond market is counted in the hundreds of trillions of dollars. Behind every one of those securities is the same ancient arrangement: someone needs money now, someone else has it, and a promise connects them. Bonds are often called safe, but that word deserves an asterisk. They are safer than stocks in many ways, yet they carry real risks that every investor should understand before buying. Interest rate risk is the big one. Because bond prices move opposite to interest rates, a rise in rates pushes the price of existing bonds down. The sensitivity is measured by duration, a number expressed in years. As a rough rule, a bond or fund with a duration of seven years will lose about 7 percent of its value if rates rise by one percentage point, and gain about the same if rates fall by one. Longer-maturity bonds have higher durations and swing more. If you hold an individual bond to maturity, these price swings on paper do not change the cash you ultimately collect, but a bond fund never matures, so its price movements are very real. Credit risk, also called default risk, is the chance that the issuer cannot pay what it promised. A company can falter, a city can go bankrupt, and a government can restructure its debt. Rating agencies such as Moody’s, S&P, and Fitch grade issuers to help investors judge this risk. Bonds rated BBB-/Baa3 or higher are considered investment grade, and lower-rated bonds pay higher yields as compensation for the greater chance of loss. A related danger is a downgrade: even if a company never defaults, on payments.

Inflation risk is the quiet thief. A fixed coupon buys less each year if prices rise. A bond paying 3 percent when inflation runs at 4 percent is losing purchasing power in real terms, even though every payment arrives on time. Long-term bonds are the most exposed, since they lock in a payment stream for decades. Inflation-protected bonds exist specifically to answer this problem. Liquidity risk describes how hard it is to sell a bond quickly at a fair price. Treasuries trade constantly and cheaply. Smaller municipal issues and obscure corporate bonds may trade rarely, and sellers sometimes must accept a discount to find a buyer, particularly during market stress. There are a few more subtle hazards. Call risk arises because many corporate and municipal bonds can be redeemed early by the issuer. Issuers tend to call bonds when rates have fallen, which means you get your money back precisely when reinvesting it is least attractive. That leads straight to reinvestment risk: the coupons you receive may have to be reinvested at lower rates than you originally earned. Investors in foreign bonds also face currency risk, since a falling foreign currency can wipe out interest income when converted back to dollars. Finally, there is the risk of misunderstanding what you own. Many investors learned in 2022 that a “conservative” bond fund can still lose double digits when rates surge. Bonds reduce risk across a portfolio, but they do not abolish it. The best defense is to match the bonds you hold to your timeline: money you need in two years belongs in short-term, high-quality bonds, and money you will not touch for twenty can tolerate more. The question “bonds or Treasuries?” is a little like asking “fruit or apples?” Treasuries are bonds, the specific kind issued by the U.S. Department of the Treasury to fund the federal government. The real question is how Treasuries compare with the rest of the bond universe, which includes corporate, municipal, mortgage-backed, and foreign issues. Framed that way, the comparison is genuinely useful as a rule of thumb comparison when investing in bonds.
