Lately, as the economy becomes more unstable, many people are really interested in government bonds. In particular, U.S. Treasury bonds are known as a safe asset par excellence, but honestly, not many people truly understand why that is. I want to organize what I’ve recently studied about this.

First, let’s think about what bonds are. Simply put, bonds are certificates that prove you’ve lent money. The government issues Treasury bonds to raise necessary funds, and the basic principle is the same: investors lend money to the government and receive regular interest payments. The 10-year U.S. Treasury bond is the most actively traded in the market, mainly bought and sold for investment purposes.

U.S. Treasury bonds are divided into three types based on maturity. There are T-bills for less than a year, T-notes for 1 to 10 years, and T-bonds for 10 to 30 years. Each has different characteristics, so you should choose according to your investment goals. Here’s an important point about the relationship between interest rates and yields, which many people confuse. When you buy and sell bonds, their prices change, and accordingly, the actual yield also varies. When demand increases, prices go up and yields go down; when demand decreases, the opposite happens. Ultimately, bond yields reflect investor sentiment.

What are the benefits of investing in U.S. Treasury bonds? First, since the U.S. government guarantees repayment, they are extremely safe. That’s why many investors flock to U.S. Treasuries during economic downturns. Second, they offer predictable returns. A fixed interest rate is set at issuance, and interest is usually paid every six months. This is why retirees prefer them. Third, liquidity is high. U.S. Treasuries are actively traded in the bond market, so you can sell them anytime you need. Lastly, there are tax benefits. The interest on Treasuries is only subject to federal tax and is exempt from state and local taxes.

Of course, there are risks too. When interest rates rise, the value of existing bonds falls. If inflation exceeds the interest rate, real returns decrease. For foreign investors, exchange rate fluctuations also matter. And although theoretical, credit risk also exists.

There are three ways to buy U.S. Treasuries. The first is direct purchase, either through the TreasuryDirect website, where you buy directly from the government, or through securities firms in the secondary market. The advantage is no commission, but the downside is you can only buy up to $10,000 at a time. The second is bond funds, managed by professionals, which are convenient but charge fees. The third is ETFs, which can be traded flexibly like stocks at low cost.

From a Korean investor’s perspective, it’s smart to combine U.S. and Korean government bonds. It diversifies regional risk and allows hedging against exchange rate fluctuations. When the U.S. dollar is strong, the value of U.S. Treasuries in Korean won increases. Since the economic cycles of Korea and the U.S. are not always aligned, when one is weak, the other can support the portfolio.

There are some considerations when investing. First, manage currency risk. Hedging only part of your U.S. Treasury investment while leaving the rest unhedged can balance risk and return opportunities. Second, match duration. Adjust the maturity based on the sensitivity of bonds to interest rate changes. Third, consider taxes. U.S. Treasury interest is taxed by the U.S. federal government, but due to the Korea-U.S. double taxation treaty, consulting a tax professional is recommended.

Imagine a portfolio split 50/50 between Korean and U.S. Treasuries. It can achieve both principal preservation and income generation, while also reducing dependence on a single country’s economy. Hedging only half of the U.S. Treasury holdings against currency risk allows you to manage exchange risk and potentially benefit from a strong dollar.

Ultimately, investing in U.S. bonds (Treasuries) is a good opportunity for both individuals and institutions. However, you must properly understand risks like interest rates, inflation, and exchange rates. For Korean investors, it’s wise to combine U.S. and Korean bonds appropriately to build a balanced portfolio. Choose the method that suits your situation—whether direct purchase, funds, or ETFs.
