There’s been a distinct uptick in stories about Iran’s nuclear program and the international tensions around it, but today there is something new.Oil prices are moving higher, and people I talk to who watch the markets closely believe that politics, not economics is driving the surge.As long as the oil prices stay flat, chatter about Iran’s nuclear program is just that: chatter.

You can follow the price of oil at the CNN Money site, among others. (When I went back to get the link, the price had gone over $99.)Hint to neophyte newshounds: watching the linkage between world headlines and prices on the financial markets is a good way to learn how things work — or at least how investors and traders think things work.
