Bonds and fixed income: the quiet backbone of a portfolio

Stocks make headlines, but the world's biggest market is quietly in bonds. A bond is one of the simplest ideas in finance — you lend money and get paid interest. Here's how it works, simply. This is for learning only.

What a bond is

When you buy a bond, you are the lender. The borrower (a government or a company) promises to:

  • pay you a fixed interest every year (called the coupon), and
  • return your original money (the principal) on a set maturity date.

That predictability is the whole appeal — unlike a share, you know in advance roughly what you'll get.

Who issues bonds

  • Government bonds (G-secs): the safest — the government won't default on rupee debt. India's benchmark 10-year G-sec yielded about 7.2% in late 2026.
  • PSU bonds: issued by government-owned companies; very safe.
  • Corporate bonds: issued by companies; higher interest, higher risk.

A credit rating tells you the risk — AAA is safest, and lower grades pay more to compensate for danger.

The one rule that confuses everyone

Bond prices move opposite to interest rates. If you hold a bond paying 7% and new bonds start paying 8%, yours is less attractive, so its market price falls. If rates drop, your 7% bond becomes more valuable and its price rises. You only need to care about this if you sell before maturity — hold to maturity and you get your full principal back.

How to buy bonds in India

  • RBI Retail Direct — buy G-secs directly, no middleman.
  • Bond platforms and your broker — for corporate bonds.
  • Debt mutual funds — the easy, diversified way (see the debt-fund article).

Where bonds fit

Bonds are the ballast of a portfolio — steady income and lower risk to balance the swings of equity. They rarely make you wealthy, but they keep a portfolio from being a rollercoaster. For how much to hold, see asset allocation.
