Speculative traders in Chicago last week racked up the highest number of long-euro, short-dollar contracts on record. Options traders have reported brisk business in euro calls - contracts to buy the euro at a pre-determined rate.
However, the market has been rife with rumours that the latest wave of selling has been led by foreign governments seeking to cut their exposure to US assets.
India and Russia have reportedly been selling US assets, as well as petrodollar-rich Middle Eastern investors.
China, which has $515bn of reserves, was also said to be selling dollars and buying Asian currencies in readiness to switch the renminbi's dollar peg to a basket arrangement, something Chinese officials have increasingly hinted at. Any re-allocation could push the dollar sharply lower and Treasury yields markedly higher.
