I consider the reason lies in the lop sided policy of artificial price mechanism of petro products. no doubt world crude price is increasing. But the import duties and excise duty are in the hands of this government only.They calculate these levies as a percentage of cost of material basis instead of on some lump sum basis. That means whenever there is increase in price the govt gets higher duties. So as the sales tax collected by state govts. They do not want any ceiling on these taxes / duties. With every rise in price of petro products these state govts gets paid more , more and more. This goes for payment of emplyee salaries or popular schemes of the govts.Instead if they fix a fixed tax by delinking with the price the common man need not suffer as he is today. since transport element is a considerable chunk in pricing of any product. HENCE CONTROL OF PRICES OF PETRO PRODUCTS WILL DEFINITELY YIELD GOOD RESULTS ON PRICE FRONT.
