What Are Bonds? Government and Corporate Bonds Explained

Beginner-friendly Updated June 2026

What is a bond, in plain English?

A bond is an IOU. Instead of you borrowing money, you are the lender. A government or company needs cash, so it borrows from thousands of people. Each lender gets a bond as proof.

Think of it like lending Rs 100,000 to a trustworthy neighbour. They agree to pay you Rs 8,000 every year for 5 years, then hand back your full Rs 100,000 at the end. That is a bond, just on a much bigger scale.

When you buy a stock, you own a slice of a business and your returns swing with its fortunes. When you buy a bond, you are simply a lender waiting to be paid back. That difference is why bonds are usually calmer and more predictable than shares.

How do bonds actually work?

Every bond has four simple parts. Learn these and you understand bonds.

• Face value (par): the amount the borrower returns at the end. Often Rs 100,000 or $1,000 per bond.
• Coupon: the fixed interest rate paid to you, usually once or twice a year. A 10% coupon on Rs 100,000 pays Rs 10,000 a year.
• Maturity: the end date when you get your money back. Could be 1 year, 5 years, or 30 years.
• Yield: your actual return based on what you paid. If a bond's price changes, the yield changes with it.

Here is the key seesaw to remember: when bond prices go up, yields go down, and vice versa. If you pay less than face value for a bond, you earn more than the coupon. Pay more, and you earn less.

Government bonds vs corporate bonds: what's the difference?

Bonds come in two main flavours, sorted by who is borrowing.

Government bonds are loans to a country. In Pakistan these are Pakistan Investment Bonds (PIBs) and Treasury Bills (T-bills). In the US they are Treasuries. Governments rarely fail to repay in their own currency, so these are seen as the safest bonds. The trade-off: lower interest.

Corporate bonds are loans to a company, like a bank or a power firm. Companies can go bust, so they must offer a higher coupon to attract lenders. More risk, more reward. In Pakistan, company bonds are often called TFCs (Term Finance Certificates) or Sukuk.

A quick note for faith-conscious investors: traditional interest-paying bonds are not Shariah-compliant. The halal alternative is a Sukuk, which pays you a share of real asset profits instead of fixed interest. Same goal of steady income, structured differently.

A worked example with real numbers

Say you buy one government bond:

• Face value: Rs 100,000
• Coupon: 12% per year
• Maturity: 5 years

Each year you receive Rs 12,000 in interest (12% of Rs 100,000). Over 5 years that is Rs 60,000 in coupons. At the end, you also get your Rs 100,000 back. Total received: Rs 160,000 on a Rs 100,000 investment.

The same idea works in dollars. A $1,000 US Treasury with a 4% coupon pays you $40 a year, then returns your $1,000 at maturity.

Now the seesaw in action: suppose interest rates in the economy rise after you buy. New bonds now pay more, so your 12% bond looks less attractive. If you wanted to sell early, you might only get Rs 95,000 for it. Hold it to maturity, though, and you still get your full Rs 100,000 plus every coupon. That is why holding to maturity removes most price worry.

Why do beginners buy bonds?

Bonds do three useful jobs in a portfolio.

• Steady income. Those coupon payments arrive on schedule, handy for retirees or anyone wanting predictable cash.
• Lower swings. Bonds usually fall less than stocks in a crash, cushioning your overall portfolio.
• Balance. Mixing bonds with stocks is the heart of asset allocation and a core part of diversification.

How much you hold in bonds depends on your risk tolerance. A nervous saver near retirement might hold more bonds; a young investor with decades ahead might hold fewer.

What are the risks of bonds?

Bonds are steadier than stocks, not risk-free. Watch three things.

• Interest-rate risk: if rates rise, the resale value of your existing bond drops (the seesaw).
• Default risk: the borrower might fail to pay. Rare for strong governments, real for weaker companies. Ratings (AAA is safest, down to junk) flag this.
• Inflation risk: if a bond pays 8% but prices rise 12%, you actually lose buying power. Learning to beat inflation matters even with bonds.

How to start with bonds

You don't need a fortune. In Pakistan, you can buy T-bills and PIBs through your bank or the SBP's Roshan Digital Account and Naya Pakistan Certificates. Globally, the easiest route for most beginners is a bond fund or bond ETF, which holds hundreds of bonds in one tidy package, so a single default barely dents you.

The bottom line: a bond is a loan with a clear interest rate and a clear payback date. Governments offer safety, companies offer higher returns, and both can bring steady income and balance to your money.

Key takeaways

• A bond is a loan you make to a government or company; they pay you interest, then return your original money on a fixed maturity date.
• Four parts define every bond: face value (what you get back), coupon (the interest rate), maturity (the end date), and yield (your real return based on price paid).
• Government bonds (PIBs, T-bills, US Treasuries) are safest but pay less; corporate bonds (TFCs, Sukuk) pay more to offset higher default risk.
• Bond prices and yields move opposite ways: when rates rise, existing bond prices fall, but holding to maturity returns your full face value.
• Main risks are rising interest rates, borrower default, and inflation eating your returns; a bond fund or ETF spreads default risk across many bonds.
• Sukuk are the Shariah-compliant alternative, paying a share of real asset profits instead of fixed interest.

Frequently asked questions

Are bonds safer than stocks?

Usually, yes. Bonds give you fixed payments and a promised return of your money on a set date, so they swing less than stocks. But they are not risk-free. The borrower could default, rising interest rates can lower a bond's resale value, and inflation can erode your returns. Strong government bonds are the safest; weaker corporate bonds carry more risk.

What's the difference between the coupon and the yield?

The coupon is the fixed interest rate set when the bond is issued, for example 10% of face value every year. The yield is your actual return based on the price you actually paid. If you buy a bond below face value, your yield is higher than the coupon; if you pay above face value, your yield is lower. Coupon never changes; yield moves with the price.

Can I lose money on a bond?

Yes, in two ways. If the borrower defaults, you may not get your interest or principal back. And if you sell a bond before maturity after interest rates have risen, you might sell for less than you paid. But if you hold a healthy bond to maturity, you receive your full face value plus every coupon, regardless of price wobbles in between.

How do I buy bonds in Pakistan?

You can buy government T-bills and Pakistan Investment Bonds (PIBs) through most banks or via the State Bank's Roshan Digital Account and Naya Pakistan Certificates, which are popular with overseas Pakistanis. For company exposure, look at TFCs and Sukuk. Many beginners prefer a bond fund, which bundles many bonds and spreads the risk.

Is there a halal version of bonds?

Yes. A Sukuk is the Shariah-compliant alternative to a conventional bond. Instead of paying fixed interest (which is not permitted), a Sukuk gives you a share of the profits from a real, tangible asset. It aims for the same steady income that bonds provide, but is structured to comply with Islamic finance principles.
