Government bond
Rules, protection and tax below are for China.
What it is
A loan to a national government. You hand over the money, the government pays a fixed interest payment on set dates, and at maturity it repays the original sum. Rich-country governments almost never fail to pay, which makes their bonds the reference point for what a very safe return looks like.
The catch is the price in between. A bond can be sold to someone else before maturity, and its price moves in the opposite direction to interest rates: when new bonds pay more, old ones paying less are worth less. Hold to maturity and none of that matters; sell early and it does.
Most countries let ordinary people buy directly from the treasury, cheaply, and the same bonds sit inside many funds and pensions.
How it works
- The government issues a bond with a face value, a fixed annual interest rate called the coupon, and a maturity date.
- You buy it at issue or from another holder, then receive the coupon on schedule, usually twice a year.
- The market price moves daily with interest rates and confidence in the country, so the yield you lock in depends on the price you paid.
- At maturity you receive the face value, whatever the price did in between.
The honest pros and cons
For
- Rich-country government bonds are the closest thing to a promise that exists in investing.
- You know the income and the repayment date in advance if you hold to maturity.
- They tend to hold or gain value when shares fall, which steadies a mixed portfolio.
- Direct purchase from the treasury is usually free or nearly free.
Against
- Rising interest rates push the price of existing bonds down, sometimes sharply for long maturities.
- The return is modest and can lag inflation for years.
- Bonds of weaker governments carry real default risk, and a high yield is the warning sign.
- Income is usually taxed unless the bond sits in a tax-sheltered account.

Wherever you are
- Decide the horizon first and pick a maturity that matches it, so you are never forced to sell early.
- Compare the treasury's direct-purchase route with a bond fund; direct is cheaper and predictable, a fund is simpler and spreads maturities.
- Look at the yield to maturity, not the coupon, because that is what you actually earn at today's price.
- Buy, note the payment dates, and leave it alone.
