Speculators have piled into the U.S. dollar in the wake of September’s global economic and financial turmoil. 

Since late August, the dollar index has gained over 6 percent.

The IMM speculative positioning for the dollar in the week of Sept. 20 is the highest since June 2010, according to Credit Agricole.

If the global market downturn worsened – for example, if Greek debt defaults in a disorderly fashion – analysts predict the dollar could go even higher.

“There is still plenty of scope for risk aversion to intensify which could provide a major boost to the USD. The USD index is currently trading just over 78 but during the height of the financial crisis it rose to around 89, a further gain from current levels of around of around 14%,” said Credit Agricole in a research note.

Currently, the IMM positioning on dollar longs are 11.77. 

It’s been in positive territory for only the second week and way below the all-time high of 24.83, according to Nomura Securities International.

During the European debt crisis of 2010, the IMM dollar longs managed to stay above 20 for six consecutive weeks.
