Lately, because interest rates on savings are low, many people have started looking for other options and have turned their attention to U.S. bonds. Especially during times of economic instability, investors seek safe assets like U.S. bonds, but honestly, at first, it seemed complicated.

After organizing what bonds are, I found it to be simpler than I thought. Basically, the government issues bonds to raise necessary funds, and investors buy them. The structure involves receiving regular interest payments and getting the principal back at maturity. U.S. bonds issued by the U.S. Treasury come in three main types. There are T-bills with less than one year to maturity, T-notes with 1 to 10 years, and T-bonds with 10 to 30 years.

Investing in U.S. bonds has some really attractive aspects. First, because the U.S. government guarantees repayment, they are highly safe. Second, a fixed interest rate is set at issuance, allowing for predictable returns. Third, because they are actively traded in the bond market, liquidity is high. Fourth, interest income is exempt from state and local taxes, providing tax benefits.

Of course, there are risks. The biggest issue is that when interest rates rise, the value of existing bonds falls. Also, if inflation increases, the real return can decrease with a fixed interest rate, and for foreign investors, exchange rate fluctuations are also a concern. Theoretically, there is a credit risk of the U.S. government, but practically, it’s almost negligible.

There are three ways to buy U.S. bonds. The first is purchasing directly through the TreasuryDirect website. The advantage is no management fees, but there’s a limit of $10,000 per person, and buying multiple bonds requires considerable management. The second is through bond funds. Professional fund managers create diversified portfolios of various bonds, but management fees are charged. The third is buying ETFs, which can be traded like stocks on exchanges with low fees, offering flexibility.

From a Korean investor’s perspective, the most important thing to consider when investing in U.S. bonds is exchange rate risk. Fluctuations in the dollar exchange rate can affect returns. Hedging with derivatives like forward contracts can fix the exchange rate, but this can reduce profits. Some investors hedge only part of their investment and accept the remaining exchange rate risk.

In practice, mixing 50:50 Korean government bonds and U.S. bonds creates a fairly good portfolio. Regional diversification reduces risk, and if the economic cycles of the two countries differ, returns tend to be more stable. Holding assets denominated in both won and dollars also provides a hedge against exchange rate fluctuations. When the dollar is strong, U.S. bonds tend to give higher returns in won terms, and when the dollar is weak, the Korean government bonds offset losses.

Ultimately, investing in U.S. bonds depends on your situation and risk appetite. If you want stable income and prefer to manage it yourself, buying directly is good. If you want professional help, consider funds or ETFs. It’s also advisable to consult with a professional about tax implications.
