UPDATE 1-Speculators' net long bets on U.S. dollar rose in latest week -CFTC, Reuters

U.S. dollar positioning was derived from net contracts of International Monetary Market speculators in the Japanese yen, euro, British pound, Swiss franc, and Canadian and Australian dollars. In a wider measure of dollar positioning that includes net contracts on the New Zealand dollar, Mexican peso, Brazilian real and Russian rouble, the greenback posted a net long position of $15.50 billion, up from $14.31 billion a week earlier. The U.S. dollar has risen 9% against a basket of currencies this year, helped by a hawkish Federal Reserve and heightened geopolitical tensions that have boosted the greenback's safe-haven appeal.
