Bonds primarily trade in the secondary market after their initial issuance, fluctuating in price based on several factors.
Understanding Bond Trading
Most bonds are initially issued at or slightly below their face value (par value). After this initial offering, bonds are bought and sold in the secondary market. The price of a bond in the secondary market can move above or below par depending on various market conditions.
Factors Influencing Bond Prices
Several factors affect how bonds trade and their prices:
-
Interest Rate Movements: This is the most significant factor. When interest rates rise, newly issued bonds offer higher yields to attract investors. To remain competitive, older bonds with lower fixed coupon rates become less attractive, causing their prices to fall. Conversely, when interest rates fall, older bonds become more desirable, and their prices rise.
-
Creditworthiness of the Issuer: If the credit rating of the bond issuer (e.g., a corporation or government) declines, investors may perceive a higher risk of default. This increased risk leads to a decrease in the bond's price. Conversely, an improved credit rating usually increases the bond's price.
-
Time to Maturity: Bonds with longer maturities are generally more sensitive to interest rate changes than bonds with shorter maturities.
-
Market Liquidity: Bonds issued by well-known entities like the U.S. Treasury are typically very liquid, meaning they can be easily bought and sold. Less liquid bonds, often those issued by smaller corporations or municipalities, may trade less frequently and have wider bid-ask spreads.
-
Inflation: High inflation erodes the purchasing power of future fixed income payments, leading to a decrease in bond prices.
Where Bonds Trade
-
Over-the-Counter (OTC) Market: The vast majority of bond trading occurs in the OTC market, a decentralized network of dealers who trade directly with one another and with institutional investors. This market is not a physical exchange like the stock market.
-
Electronic Trading Platforms: Electronic platforms are increasingly used for bond trading, providing greater transparency and efficiency. These platforms allow investors to view bid and ask prices from multiple dealers and execute trades electronically.
-
Exchanges: While less common, some bonds are listed and traded on exchanges.
Example
Imagine you bought a bond with a 5% coupon rate. If market interest rates subsequently rise to 6%, new bonds will be issued with a 6% coupon. To sell your existing 5% bond, you would likely need to lower its price so that its yield to maturity is comparable to the new 6% bonds. This makes the total return (coupon payments plus capital appreciation or depreciation) competitive.
In Summary
Bonds trade primarily in the secondary market. Their prices are inversely related to interest rate movements and are also influenced by the issuer's creditworthiness, time to maturity, market liquidity, and inflation. The majority of trading occurs over-the-counter.
