I'd say Atilla is right..inflation is a consequence, not the effect. If you have to pay more for a commodity, that means I need more money to pay for it. That requires both an increase in money supply, and the price is increasing. Thats your original definition and contemporary sorted.
Gold will surely increase if oil does. We mine gold and that requires oil. If oil increases, the cost of production globally increases for practically every commodity. the cost of extraction goes up, your raw material price also goes up. The cost of labour also goes up, as I have to pay more to pay for that oil to drive me to the mine so the increase in the price of oil now has a knock on effect for every part of the manufacturing process in determining the base cost of your raw material..Gold
