Speculators turned against the US dollar in the latest week, according to Commodity Futures Trading Commission data released on Friday. The value of the dollar's net short position was around $2.7 billion in the week ending January 12, shifting from a net long of $4.25 billion the previous week, according to Reuters calculations.

This was the first net short position on the dollar since December 15. The Reuters calculation for the aggregate US dollar position is derived from the net positions of International Monetary Market speculators in the yen, euro, British pound, Swiss franc, Canadian and Australian dollars.
