NYMEX-Crude down on economic worry, trading choppy

* Wall Street opens higher, then turns negative

* More attacks in Nigeria

NEW YORK, July 13 (Reuters) - U.S. crude futures fell on
Monday in seesaw trading as persistent concerns about economic
recovery continued to pressure oil markets also weighed by
swollen inventories and tepid demand.

Crude had bounced off its early low, helped by a bounce by
Wall Street on banking sector optimism.

"(A) Monday rally following a sharp $16 crude price
downdraft would not be unusual," Jim Ritterbusch, president at
Ritterbusch & Associates in Galena, Illinois, said in a note.

"However, the complex is running out of fresh bullish
ammunition needed to sustain a price correction of more than
$2-$3," Ritterbusch added.

U.S. stocks opened higher after influential bank analyst
Meredith Whitney gave a bullish assessment of the financial
sector's likely performance, but then turned negative. [.N]

European shares bounced up after Wall Street looked set for
a positive start, but world shares were lower, with
particularly heavy losses in emerging markets. [MKTS/GLOB]

Trading sources noted that both August and September Brent
crude were at a premium to NYMEX benchmark West Texas
Intermediate, but were reluctant to point to the Nigerian
turmoil as the cause, considering the high inventories and
remaining floating storage around the globe.
