Oil and diesel prices are climbing again as the US builds up forces near Iran, and that is bad news for drivers, truckers, farmers, and anyone already stretched thin.

• Brent crude jumped about 5% after word that a third US aircraft carrier and up to 10,000 more troops are heading to the Middle East.
• Chinese refiners suspending fuel exports made it worse, and diesel supply is tight because refineries in Russia and China are running low or holding product back.
• The oil industry says diesel won't get back to normal for at least a year, which raises the cost of nearly everything that moves by truck or plane.
• Mortgage rates just posted their biggest weekly jump in four years, so borrowing is getting more expensive at the same time.
• Evictions are spiking in metro Atlanta at three times the national rate, and Nike's sales miss shows shoppers pulling back.

Outlook: Expect more announcements promising cheaper diesel, but high gas prices, higher borrowing costs, and more weak company results look likely in the months ahead.
