Oil company defaults are spiking

``Defaults are skyrocketing again. In December, exploration and production company defaults topped 11%, up from just 0.5% the previous year, according to Fitch Ratings. That's a 2,000%-plus jump. It's just the beginning, says John La Forge, head of real assets strategy at Wells Fargo. If history repeats, people should prepare for the default rate to double in the next year or so.''
