I am no financial expert but I do think it will hurt the US/canada economy somewhat but until the US loses the petro dollar it shouldn't hurt that much. But it might be the start of the fall of the petro dollar and that would hurt the economy like nothing before! Imagine if you were used to getting goods like gold,food,medicine,etc.. for nothing! (printed paper) And then that was taken away = disaster

I made a short post on the petro dollar.... feel free to let me know what you think
