NEW YORK, Sept 14 (Reuters) - Speculators' net long bets on the U.S. dollar fell to the lowest since mid-July, according to calculations by Reuters and Commodity Futures Trading Commission data released on Friday.
The value of the net long dollar position was $19.16 billion in the week ended Sept. 11, down from $20.60 billion the previous week. Speculators have been net long dollars for 13 straight weeks, after being net short for 48 consecutive weeks.
U.S. dollar positioning was derived from net contracts of International Monetary Market speculators in the yen, euro, British pound, Swiss franc and Canadian and Australian dollars. (Reporting by Gertrude Chavez-Dreyfuss Editing by Susan Thomas)
