Economy depression ma gayo bhane dollar ko bhau tank huncha. What does it imply for the petro-dollar is people had to pay more dollars to buy the same oil. This will increase the price of the oil. Even though it will hamper the small company but big companies will survive. If you look around last recession the oil price was highest since the dollar value was low. So, I think this will happen again. Although the price maynot reach around $130 but definitely around 80-100
