A worrying vicious cycle

raised by the American Geological Institute, via Mark Perry:

If the US dollar had remained strong in the global economy, oil might, in theory, be around $65 per barrel. However, oil is priced in dollars, and oil prices continue to rise. The impact of increased oil prices can not be ignored in the US economy, and, in turn, can further weaken the dollar. Resource economics is a complex feedback loop where today’s resource boom is driven by many external factors. This complex system bears watching by all geoscientists.
