Oil hit 100 dollars a barrel. Why does your petrol bill care?

News reports say crude oil crossed 100 dollars a barrel this month. Let us follow that oil from a faraway well to your petrol bill, and then to the market screen.

Let me draw it for you both. Here is the real question: how does oil from far away end up in a petrol bill, and why does the stock market care?

Step 2 of 7 · Guess

Guess first

Crude oil is oil straight out of the ground, before it is turned into petrol.

When crude oil gets more expensive, what else gets more expensive?

Yes. Trucks run on diesel, made from the same oil. So the cost slowly reaches vegetables, milk and phones. Let us see what is inside one litre first.
Step 3 of 7 · Build

What is inside one litre?

You pay ₹100 for a litre of petrol. Where does that ₹100 go? Tap each piece to build the price.

These amounts are made up to show the idea. Real ones change by state and by day.

One litre costs₹55
Taxes inside it₹0
Follows world oil₹55

Now add the other pieces.

Step 4 of 7 · Concept

Why does the market care?

When oil gets expensive, some companies earn more and some pay more. Same news, opposite effects. Tap to see both sides.

Oil goes up. They smile.

Who
Oil producers and drillers
Why
Each barrel they sell brings in more money
Their shares
May rise

Oil goes up. They wince.

Who
Airlines, delivery firms, and makers of paint and tyres
Why
Fuel or oil based ingredients cost them more, and profit shrinks
Their shares
May fall

India is on the wrong side of this more often than not. About 85% of the oil it uses comes from other countries, and it pays in dollars. So a costly barrel is a big bill for the whole country.

This is why oil headlines show up on the Sensex and Nifty screens from Chapter 3.

Step 5 of 7 · Why it matters

What it does to your month

Say you use 20 litres a month. At ₹100 a litre, that is ₹2,000. Only the oil piece (₹55) follows the world price. Drag how much oil rises, then pick what the rupee does. These are made up scenarios.

Oil is paid for in dollars. If the rupee weakens, each dollar costs more rupees, so the same oil costs more in rupees.

Drag the slider
Meanwhile the rupee…
One litre now₹111
Your monthly petrol₹2,220
Extra each month₹220

Dashed line = ₹2,000, what you paid before

Oil rose 20%, but the litre rose only 11%, because most of the price is tax and delivery. Still, trucks run on diesel, so the rise also creeps into food and shop prices.

Step 6 of 7 · Before and after

Same oil news. Two reactions.

Tap to see each reaction.

Blames the pump

First move
Complains to the petrol pump guy
The budget
Unchanged, so money runs short early
The shares
Sold in a panic when the headline scares
Result
Stressed, short by the 20th, and out of the market

Follows the chain

First move
Asks how much of the price actually follows oil
The budget
Adds a small petrol buffer and shares one ride a week
The shares
Oil is one clue, not a prediction, so nothing changes in a panic
Result
Small change to the budget, calm about the market
Tanishq
so oil makes vegetables expensive too?
7:20
Nemi
Yes. Trucks run on diesel. That is inflation from Chapter 1, arriving at the sabzi shop.
7:20
Dhvani
so everything is connected 😭
7:21
Nemi
It is. And it is okay to feel that. Then we make a small plan.

Step 7 of 7 · Answer

Last one. Oil jumps. Now what?

The headline says oil has jumped. What is the smartest reaction?

Yes. Follow the chain first, then decide.
Oil is far away. The bill is at home.Follow the chain from the well to your wallet, then decide. Do not follow the panic.
