EUR/USD continued its fall on Monday as traders continue to sell off any and everything against the USD. The EU is a hotbed of doubt and fear right now, so we see this as a "sell the rally" type of market at this point.
AUD/USD followed suit as the USD is without a doubt the currency everyone wants currently. With the global economy in doubt, the demand for commodities should continue to fall, something that works against the Aussie in a major way.
