When you look at economic news these days, you often see discussions about investing in U.S. bonds. As interest rates fluctuate more sharply and global uncertainty grows, it’s an area attracting increasing attention among Korean investors too. U.S. government-issued Treasury bonds are widely regarded as the safest assets in the world—but how can you actually invest in them?

Let’s first go over the basics of U.S. Treasuries. Because these bonds are issued by the U.S. government based on its credit, there is virtually no default risk. From an investor’s point of view, it’s a structure where you lend money to the government, receive a fixed amount of interest, and have your principal repaid at maturity. This is the asset that global investors look for first during times of crisis.

Depending on maturity, they can be broadly divided into three categories. Treasury Bills with a term of less than 1 year are issued at a discount; there is no separate interest payment, and they are redeemed at face value at maturity. Since they have relatively low interest-rate risk, they are suitable for short-term fund management. Treasury Notes with maturities of 2 to 10 years are the most actively traded, and especially the 10-year note is frequently used as a benchmark interest rate. They pay interest every six months. Treasury Bonds with maturities of 20 to 30 years offer relatively higher interest rates, but the price can fluctuate significantly due to changes in interest rates.

So, what are the ways to actually invest in U.S. bonds? The most direct method is to buy them directly through the U.S. Department of the Treasury’s TreasuryDirect site. You can start with as little as 100 dollars, and one of the advantages is that there are no fees. Another option is to use overseas bond trading services offered by domestic securities firms, but the minimum trade amount varies by broker. The third option is ETF investing: you can invest in U.S. Treasury bond-based ETFs managed by companies such as iShares or Vanguard. In particular, if you choose a currency-hedged (H) product, you can minimize gains or losses caused by exchange rate fluctuations.

It’s also important to understand Treasury yields. Yield to maturity (YTM) refers to the total return you can earn if you hold a Treasury bond until maturity. Bond prices and yields have an inverse relationship—when prices rise, yields fall, and vice versa. Current yield is simply the annual interest divided by the current price. As of early last year, the 10-year Treasury yield was reported to be around 4.54%.

When looking at factors that affect U.S. bond investments, the Federal Reserve’s interest rate policy is the most direct. When interest rates rise, the appeal of existing Treasuries declines, and their prices fall. If inflation increases, investors demand higher yields, which is also negative for Treasury bond prices. When the economy grows, interest rates tend to rise, and this increases Treasury yields. The scale of government Treasury bond issuance also matters: when supply increases, prices fall and yields rise.

Overseas factors can’t be ignored either. As uncertainty in the global economy increases, demand for safe assets like U.S. Treasuries rises, which can actually push prices up. When war or political instability occurs, investors flock to U.S. bonds. Fluctuations in other asset markets—such as stocks or real estate—also affect the Treasury market.

There are points you should consider when investing in practice. U.S. Treasuries are safe, but their yields are relatively low. However, if you factor in currency gains, the actual return may be higher. Conversely, there is also the risk of currency losses, so you should be careful about this aspect. You need to make an investment decision by comprehensively evaluating multiple factors such as interest rate changes, foreign exchange risk, and inflation.

When comparing U.S. Treasuries with other investment assets, Treasuries are superior in terms of stability and liquidity. The trustworthiness of the U.S. government and the almost nonexistent default risk are strong advantages. However, the upside potential in returns is limited. On the other hand, U.S. stocks can be highly volatile depending on corporate performance and market news, but on average they tend to be more profitable than bonds. Most stocks are also liquid enough to buy and sell at any time.

In conclusion, investing in U.S. bonds is a key way to understand the global financial market and a representative safe asset. In the face of recent economic uncertainty, its importance has only grown further. Korean investors can also use U.S. bonds to prepare for fluctuations in the value of the Korean won and diversify portfolio risk. However, you should approach it carefully by considering interest rates, exchange rates, inflation, and other factors in combination. Choosing the type of Treasury bond that fits your investment objectives and risk tolerance is the first step toward effective asset management.
