OK little boy let me tell you what is the benefit we are getting with lower oil price according to your mantle level.
For example Pakistan requires 100 litre oil (we calculate normally based on per barrel but this is for your easy understanding)
100 litre=$120 before oil price reduce
now
100 litre=$50
Saving =120-50=S70 per 100 litre.
Before oil price reduce Pakistan spending $6.4Bn and now due to reduce in price
“Oil imports constitutes 36 per cent of Pakistan’s total import bill and a 30pc decline in oil prices is likely to result in annual savings of $4bn (1.5pc of GDP),” said a research report issued by Topline Securities.
So Pakistan get Additional saving of $4bn and Govt increase tax on oil also. So bottom line as i stated above
Pakistan spends $6.7bn on oil import - Pakistan - DAWN.COM
