    NEW YORK, Sept 30 (Reuters) - Speculators boosted net longs
on the U.S. dollar to their highest in six weeks, Reuters
calculations and data from the Commodity Futures Trading
Commission showed on Friday, in a volatile week that saw the
greenback rack up gains as a safe haven due to the troubles at
Deutsche Bank.
    The value of the dollar's net long position rose to $9.7
billion in the week ended Sept. 27, from $6.6 billion
previously, the data showed.
    The dollar index ended flat on the week, but was down 0.6
percent for the month of September. Deutsche, which is Germany's
largest bank, has been engulfed by crisis after being handed a
demand for up to $14 billion by the Department of Justice for
misselling mortgage-backed securities.
    "Risk aversion should keep the greenback bid against
currencies like the euro, British pound, Australian and New
Zealand dollars," said Kathy Lien, managing director of FX
strategy at BK Asset Management in New York.
    That said, the case for a December rate hike remained firmly
in place with Friday's economic data supporting that, analysts
said, which should underpin the dollar in the short term.
    In addition, this week's line-up of Federal Reserve speakers
showed a "more forceful voice building" for a December
tightening, said Marvin Loh, senior global markets strategist,
at BNY Mellon in Boston.
    The yen net long position, meanwhile, rose to a five-month
peak of 68,892 contracts, data showed, in the aftermath of the 
Bank of Japan's decision last week to target Japanese government
bonds' long-term yields.
    Investors believed the BoJ will be unable to prevent the yen
from strengthening further, noting that the currency has further
room for gains. So far this year, the yen has climbed nearly 19
percent against the dollar, on pace for its best yearly
performance since the global financial crisis in 2008.
    Data also showed that the Mexican peso's net short position
eased this week to 85,873 contracts, from a record level the
week before.
