Low oil price and impact Today I read  an artcicle about the falling oil price (maybe it'll go under 30$ per barel the next days). Why is this a bad news? Lower oil price can give an advantage for a higher productivity.
It is not necessarily bad news. 

Simply put, if you're willing to buy product x (bread, car, house, ect.) then falling prices are good news for buyers, but bad news for the sellers. The same logic applies for oil. If you are a buyer, you are optimistic about falling prices, however being a seller would make you loose money and/or postpone new investments.
