It's merely a coincidence.. The price of OIL and the price of COPPER have been in flux for years... Precisely why in america they want to get rid of the penny... it will soon cost more than a penny to make them. Just imagine if they were solid copper like the old wheat backs.
everything does to some degree cos of the oil used in production packaging and transportation, and because wire is used in massive quantities in industry the companys selling it would lose out if they didnt increase there costs immediatly.
It follows the copper market. During high economic growth periods, copper (for wiring) oil for fuel are both simultaneously in high demand.
Doh!! The reason the prices of wire follow the prices of oil, the outer jacket of Wire is Plastic an oil based product, Thus the reason oil goes up so does the prices of wire.
