Complete Guide to Bond Investment: Higher Returns than Savings, Safer Choice than Stocks

As of 2025, what is the most attention-grabbing investment asset in the personal finance market? It is 바로 bonds. Recently, with expectations of interest rate cuts, the value of bonds has been highlighted, but bonds are not just about providing simple interest income. They are a comprehensive investment solution that offers high asset stability, predictable cash flow, and tax-saving benefits.

What Are Bonds? Understanding from the Basics

A bond can be defined in one sentence as a debt certificate issued by governments, corporations, or public institutions that promises to return the funds along with interest at a later date. From an investor’s perspective, purchasing a bond means lending money to the issuer and gaining the right to receive regular interest payments and the principal at maturity.

By 2025, the attractiveness of the bond market is clear. The annual yield on 3-year Korean treasury bonds is around 3.3%, which is higher than bank fixed deposits and backed by government guarantees, making it extremely low-risk. Recently, innovative products such as blockchain-based digital bonds and ESG( environmental, social, and governance) bonds continue to emerge, rapidly expanding the variety of bond products available to investors.

Bonds vs. Fixed Deposits: Same Interest Income, Different Structures

Many novice investors confuse bonds with fixed deposits. Both earn interest, but their mechanisms are entirely different.

Fixed deposits involve depositing money in a bank and receiving the promised interest after a fixed period. According to the Deposit Insurance Act, principal up to (50 million) will be protected, with plans to increase this to (100 million) this year. Early withdrawal results in reduced interest.

In contrast, bonds depend on the creditworthiness of the issuer to determine the yield. They can be freely bought and sold in the bond market before maturity, and if interest rates fall, existing bonds’ prices rise, allowing for capital gains. When investing directly, only interest income tax applies, and capital gains from trading are tax-exempt.

Five Key Characteristics of Bonds

1. Stability: Credit Ratings Reflect Trust

The biggest advantage of bonds is their stability. High-grade corporate bonds with AAA ratings or government bonds offer almost no risk of principal loss, providing safety comparable to deposits. The higher the issuer’s credit rating, the higher the likelihood of principal and interest repayment.

2. Regular Interest Income

Most bonds pay interest every 3 to 6 months. As of 2025, the coupon rate on 3-year Korean treasury bonds is around 2.3–2.4%, and highly rated corporate bonds can offer 4–6% interest. This is highly attractive for investors who need predictable, regular cash flow.

3. Excellent Liquidity

The Korean bond market is very active, with an average daily trading volume of about 25 trillion won in the first quarter of 2025. The ability to cash out anytime when needed is a significant difference from fixed deposits.

4. Price Volatility Due to Interest Rate Changes

When interest rates fall, existing bonds’ prices rise; when rates rise, prices fall. Properly leveraging this characteristic can allow investors to profit from trading based on interest rate outlooks.

( 5. Tax Benefits

Investors who directly purchase bonds are taxed only on interest income, while capital gains from trading are fully tax-exempt. ESG bonds may also offer additional tax benefits.

Yield and Risk by Bond Type

Bonds vary significantly depending on the issuer.

Government bonds are issued by the government, so they have the highest credit rating but generally offer lower yields. They are the safest choice.

Special bonds are issued by public enterprises like Korea Electric Power Corporation or toll road authorities. They carry slightly more risk than government bonds but remain stable with higher yields.

Local government bonds are issued by local authorities, offering slightly higher returns than government bonds.

Financial bonds are issued by banks or financial institutions, with high liquidity suitable for short-term funds.

Corporate bonds are issued by private companies. Yields vary greatly depending on credit ratings, so checking creditworthiness before investing is essential.

U.S. Treasury bonds are globally recognized safe assets, offering diversification in dollar assets and currency hedging benefits, favored by international investors.

Three Hidden Risks in Bond Investment and How to Address Them

Just because bonds are considered safe doesn’t mean they are risk-free. There are three key risks that beginner investors must understand.

First, rising interest rates lead to falling bond prices

When the central bank raises the base interest rate, the prices of existing bonds decline. For example, if you buy a bond paying 3% interest and market rates rise to 4%, the bond’s attractiveness diminishes, and its price drops. If interest rates are expected to rise, choosing short-term bonds of 1–3 years or floating-rate bonds is wise.

Second, issuer’s credit deterioration

In corporate bonds, if the issuing company’s financial health worsens, you may not recover the principal. Lower credit-rated bonds carry higher risk. Risk-averse investors should prioritize high-grade bonds like AAA or AA.

Third, exchange rate fluctuations affecting gains and losses

Foreign bonds are mainly traded in dollars. Exchange rate movements can alter the realized gains or losses when converted back to won, even if interest income remains the same. If currency risk concerns you, consider currency-hedged ETFs or diversifying with some dollar assets to spread risk.

Who Should Consider Bond Investment

Bond investments are especially suitable for certain investors.

Those needing regular cash flow can benefit from the predictable income from interest payments. Retirees or those approaching retirement can pursue higher yields without exposure to large price swings typical of stocks.

Investors who find stock market volatility stressful can use bonds as an excellent asset allocation tool. Combining stocks and bonds can effectively reduce overall portfolio risk.

Those interested in tax savings or global diversification can also leverage the tax benefits and currency hedging effects of dollar-denominated bonds.

Three Ways to Invest in Bonds
