People who are about to start investing in bonds often have the first question: "What does bond mean?" followed by "Can I invest in it?" Honestly, bonds are much simpler than you might think.

A bond is a type of "loan certificate" issued by governments, companies, or public institutions when they need funds, promising to pay a fixed interest rate in return for borrowing money from investors. From an investor's perspective, simply buying a bond provides regular interest income, and at maturity, the principal is returned. As of 2026, bonds are attractive because they can offer higher returns than bank savings accounts while not being exposed to the large volatility typical of stocks.

To properly understand what bonds are, you need to know some key characteristics. First is stability: government bonds or high credit rating corporate bonds have almost no risk of principal loss. Second is regular interest income: most bonds pay interest every 3 to 6 months. Third is high liquidity: you can sell bonds freely in the market before maturity, which helps when cash is needed urgently. Fourth is that bond prices fluctuate with interest rate changes. Fifth is that there are tax benefits: when investing directly, you only pay interest income tax, and there’s no tax on capital gains from trading.

However, there is an important point to note. Bonds are not absolutely safe. When interest rates rise, the prices of existing bonds can fall, and issuers may face financial difficulties and be unable to repay the principal. For foreign bonds, there’s also exchange rate risk. Therefore, for beginners, it’s wise to start with government bonds or bonds issued by highly rated companies.

There are various types of bonds. Government bonds are issued by the government and are the safest, but generally offer lower interest rates. Special bonds are issued by public enterprises like Korea Electric Power Corporation. Corporate bonds are issued by regular companies, and their interest rates vary greatly depending on credit ratings. There are also municipal bonds, financial bonds, and even foreign bonds like U.S. Treasury bonds.

Many people confuse bonds with fixed deposits, but they are definitely different. Fixed deposits guarantee the principal by the bank, but offer lower interest rates. Bonds depend on the issuer’s creditworthiness for principal repayment, but generally provide higher yields. Also, fixed deposits incur losses if you cancel early, whereas bonds allow you to benefit from price increases when interest rates fall.

Once you understand what bonds are, it’s time to think about how to invest. You can buy individual bonds directly, or invest in bond funds or bond ETFs, which are traded like stocks. Each has its pros and cons, so choose based on your investment style and capital size.

Recently, expectations of interest rate cuts have increased, making bond prices potentially rise. Now might be a good time to start investing in bonds. I recommend understanding the basics of bonds, starting with relatively safe products like government bonds or high-quality corporate bonds, and gradually expanding your portfolio. For investors seeking stable income and risk diversification, bonds can be an essential option you shouldn’t miss.
