Recently, there has been a significant increase in Korean investors showing interest in U.S. Treasury bonds. As interest rate fluctuations become more volatile and economic uncertainties grow, the movement to seek safe assets is becoming more pronounced. From my perspective, simply understanding how to invest in bonds properly can make a considerable difference in portfolio stability.

Let's start by considering why U.S. Treasury bonds are attracting so much attention. The core is that they are debt securities issued by the U.S. government, and because they are backed by the credit of the U.S. government, there is virtually no risk of default. From an investor's standpoint, it’s a structure where you lend money and receive fixed interest payments, with the principal returned at maturity. This is precisely why global investors prefer them.

Understanding the types of government bonds is fundamental to bond investment strategies. Short-term bonds under one year are issued at a discount, which means they have low interest rate risk and are ideal for short-term cash management. Medium-term bonds between 2 and 10 years are traded most actively, especially the 10-year bonds, which serve as the benchmark for long-term interest rates. Since they pay interest every six months, they are popular among those seeking stable income. Long-term bonds of 20 or 30 years offer relatively higher yields but come with greater price volatility due to interest rate fluctuations—this is the trade-off.

Grasping the concept of Treasury yields is crucial; it refers to the expected return you can earn from holding the bond. The yield to maturity (YTM) indicates the total return if you hold the bond until maturity and is inversely related to the bond’s price. When the price rises, the yield falls; when the price drops, the yield rises. The current yield is calculated by dividing the annual interest payment by the current price, and it’s used as a benchmark when comparing interest rates across different investment assets.

Factors influencing Treasury bond prices are more complex than they seem. Federal Reserve interest rate policies directly impact them, and higher inflation causes investors to demand higher yields. Economic growth generally leads to rising interest rates, which in turn increase Treasury yields. Government spending and debt levels are also important—more issuance of Treasury bonds tends to lower prices and raise yields. Externally, increased global economic uncertainty often boosts demand for safe assets like U.S. Treasuries, pushing prices up. War and political instability also drive investors toward Treasury bonds.

There are three main ways to invest in bonds. First, directly purchasing through the U.S. Treasury’s TreasuryDirect website, which requires a minimum of $100 and charges no fees. Second, using overseas bond trading services offered by domestic securities firms, which have varying minimum transaction sizes and amounts. Third, investing via ETFs—many asset management companies both domestically and internationally have launched U.S. Treasury-based ETFs. Typically, these are 10- to 30-year maturity products, such as the iShares 7-10 Year Treasury Bond ETF (IEF) or Vanguard Long-Term Treasury ETF (VGLT).

Exchange rate issues are also critical. Since U.S. Treasuries are considered highly safe, their yields tend to be lower, but when factoring in currency gains, the actual returns can be higher. Conversely, there is a risk of currency losses, so caution is needed. Domestic market hedged ETFs (H label) minimize currency gains and losses caused by fluctuations in the dollar exchange rate.

Compared to U.S. stocks or CFDs, the position of Treasury bonds becomes clearer. Treasuries excel in stability and liquidity, backed by high government trust, making them ideal for investors seeking steady returns. However, their main drawback is relatively low yields. Stocks tend to have higher volatility depending on corporate performance but generally offer higher average returns. CFDs have very high volatility and profit potential but also carry significant risk of loss.

Ultimately, choosing a bond investment method depends on accurately understanding your investment goals and risk tolerance. It’s essential to consider various factors such as interest rate changes, currency risk, and inflation comprehensively. U.S. Treasuries are not just simple investment products—they are key indicators for understanding the global financial market and serve as a representative safe asset. In today’s uncertain economic environment, their importance is even more pronounced. Korean investors can also diversify risk by securing stable dollar assets to hedge against won fluctuations. Selecting the right type of Treasury bond to fit your portfolio is a wise move toward building an effective investment strategy.
