Have you ever wondered why so many people only talk about stocks but rarely mention bonds? I used to have that same question until I started digging deeper into financial investment channels. It turns out that bonds are one of the safest ways to invest—especially for people who want to increase passive income without taking on too much risk.

What is a bond? Simply put, it is a type of debt security. When you buy a bond, you are essentially lending money to an organization (which could be the government, a bank, or a company), and they commit to paying you interest on a specified schedule. Unlike stocks, where you become a shareholder, bonds make you a creditor of the issuing organization.

In Vietnam, the corporate bond market has grown impressively, with an average increase of 35% per year from 2016 to 2020. This clearly shows the potential of this investment type, but many new investors still don’t fully understand bonds and how they work.

There are two main types of bonds in Vietnam: government bonds and corporate bonds. Government bonds are very safe because they are issued by the state, offer fixed interest rates, and have maturities ranging from 5 to 30 years depending on the type. Corporate bonds are issued by companies and banks to raise capital, with shorter maturities (1–3 years); their interest rates may be fixed or floating, but the risk is relatively higher as well.

If you want to start investing in bonds, the first step is to open an account at reputable securities companies such as VPS, MBS, Vndirect, or SSI. The process is very simple and takes only a few minutes to enter your personal information. Then, you have two options: invest directly by signing a contract with the issuer, or invest through a bond fund if you want to reduce risk.

With direct investment, you need an average capital of about 100 million VND, but if you choose a bond fund, you only need 5–10 million VND. The process is fairly straightforward: sign the contract, transfer the money, receive the certificate, and then wait to receive interest in the scheduled periods.

When choosing which bonds to buy, you should prioritize reputable issuers such as the government, major banks (Techcombank, Vietinbank, Vietcombank, HDbank), or leading companies in the industry. This helps minimize credit risk—that is, the risk that the issuing organization may be unable to make payments when due.

There are three main types of risk when investing in bonds that you need to know: credit risk (default), prepayment risk (being paid earlier than expected, which causes interest rates to drop), and interest rate risk (interest rates changing not according to expectations). These risks are not that large, but it’s important to understand them clearly.

Compared with stocks, bonds are safer but offer lower returns. Foreign stocks are a different story—lower capital and two-way profits (you can gain or lose), but the risks are also much higher. Therefore, choosing an investment method depends on your financial goals and your level of risk tolerance.

The downside of bonds is that they have a minimum term of 1 year, which makes them less appealing to young investors who want to make profits quickly. But if you have some idle money and want to increase stable income, bonds are definitely worth considering.

In summary, what is a bond? It is a reasonable, safe financial investment approach suitable for people who want to preserve capital and generate passive income. With Vietnam’s bond market growing strongly, this is a good time for you to learn about it and get involved. Just having basic knowledge of terms such as coupon, par value, and maturity date is enough for you to begin your bond investing journey.
