UPDATE 1-Speculators cut negative dollar positions to lowest since July -CFTC, Reuters

    Nov 17 (Reuters) - Speculators cut their bearish bets on the
U.S. dollar for the seventh straight week, with the net negative
value of positions against the greenback falling to a four-month
    Calculations by Reuters of data from the Commodity Futures
Trading Commission (CFTC) showed bets on the dollar totaled
negative $643 million, the lowest since mid-July when
speculators held a net-positive position in the dollar.
    Short bets against the dollar have extended their decline as
the year has progressed and bets on another U.S. interest rate
increase from the Federal Reserve have been almost entirely
priced into the dollar.
    Fed funds futures rates show market investors see a 91.5
percent chance of a rate hike at the Fed's next meeting in
December, raising the U.S. overnight interest rate to 1.25-1.50
percent, while 8.5 percent see an increase to 1.50-1.75 percent
and zero percent of investors see the rate remaining at its
current 1.00-1.25 percent level.
    Speculators' net short position in the Japanese yen grew to
its largest since December 2013 as traders continued to bet that
the yen would fall.
    Investors' preference for borrowing at low rates in one
currency to invest in another with higher returns creates
selling pressure on low-yielding currencies such as the yen.
    To be long a currency means making a bet that the currency
will appreciate, while to be short a currency means betting that
it will depreciate in value.
    The Reuters calculation for the aggregate U.S. dollar
position is derived from net positions of International Monetary
Market speculators in the 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 ruble, the U.S. dollar posted a net
short position valued at negative $2.41 billion, compared with
negative $3.69 billion a week earlier. 
    That is the closest speculators' bets on the dollar have
been to even in that metric since they were net-positive on June
