Chennai Petroleum, MRPL shares surge as crude oil prices climb

A refinery is a factory that turns crude oil into things we use every day, like petrol, diesel and jet fuel.

Two Indian refinery companies, Chennai Petroleum and MRPL, saw their stock prices jump on Tuesday.

The reason is that the price of crude oil went up.

When crude prices stay high, refiners can sometimes earn more money from the fuel they make and sell.

The difference between what they earn from fuel and what they pay for the oil is called the gross refining margin.

Oil prices rose because people hoped the United States and Iran would make a deal to reopen the Strait of Hormuz, an important sea route for oil ships, but that hope faded.

This made oil prices climb higher, and investors bought refinery shares because they expect these companies to benefit.

Experts say the companies reported strong results for the first quarter, which also made investors more confident.

If oil prices stay high, these companies could keep doing well in the short to medium term.
