Rise in Asian and American markets

A spectacular rise was seen in the Asian stock markets on Monday. South Korea’s Kospi index was seen trading at the level of 7848 with an increase of 32 points or 0.41%. At the same time, Japan’s Nikkei index reached the level of 65226 with an increase of 1887 points or 2.98%.

Market excited by Iran-US peace agreement

The biggest reason for the rise in the market is considered to be the possible peace agreement between Iran and America. US President Donald Trump had recently claimed that the agreement to end the war with Iran has almost reached the final stage. He said that work is going on on the final details between the two countries and this agreement can be finalized after talks with the leaders of the Gulf countries and the Israeli Prime Minister.

Trump also said that the Strait of Hormuz will be reopened under the agreement. It is considered to be the world’s most important maritime oil route, through which about 20% of the global oil supply passes. In such a situation, if this route opens normally then a fall in crude oil prices may be seen.

Prices of other things may also increase

Now the cost of petrol and diesel can affect everyday things also. Due to increase in truck and tempo fares, vegetables, fruits and ration coming from other states may become expensive. The cost of farming will also increase. Farmers will have to spend more to run tractors and pumping sets, which may increase the prices of grains and other agricultural products. Apart from this, there may also be an increase in the fares of bus, auto and school vehicles.

How are the prices of petrol and diesel decided?

Fuel prices in the country are decided based on the prices of crude oil in the international market and the position of the rupee against the dollar. Government oil companies update new rates every day at 6 am under ‘Daily Price Revision’. India imports about 90% of its crude oil requirement from abroad. The increase in the price of crude oil in the international market has a direct impact on the prices of petrol and diesel.

Crude oil is purified in refineries to make petrol and diesel. After this the central government imposes excise duty and road cess. Then dealer commission is added and finally the state governments impose VAT or local tax as per their discretion. This is the reason why prices of petrol and diesel differ in different cities like Delhi, Mumbai, Kolkata and Chennai.
