Currency speculators cut their bets against the dollar for the first time since mid June and slashed their bets against the low-yielding yen and Swiss franc, data from the Commodity Futures Trading Commission showed on Friday.
The value of the net short US dollar position in the week to July 31 decreased to $22.8 billion from $26.6 billion in the prior week - the smallest net short position since the July 3 week.
The aggregate dollar position is derived from the net positions of International Monetary Market speculators in yen, euro, British pound, Swiss franc, Canadian and Australian dollars.
