NEW YORK/LONDON, May 25 Copper climbed more than 2 percent on Wednesday, on buying
spurred by recent bullish investment bank outlooks amid mounting evidence of a production
short-fall this year.
Macquarie Bank's removal of its short-term sell in copper a week ago and Goldman Sachs'
recommended long position this week seem to back what many long-term bulls have been betting on --
that supply growth in 2011 will fall well short of rising global demand. [ID:nWNAB0808]
Another bullish call came from commodity giant Glencore on Tuesday, forecasting that buoyant
demand from emerging markets in Asia should underpin growth in commodities as global producers
strive to keep pace with booming appetite from the region. [ID:nL3E7GP0EY]
"All the banks have been putting out buy calls on copper... I think we are seeing an uptick in
investment demand for longer term investors," said Catherine Virga, senior base metals analyst with
CPM Group in New York.
That investment demand helped copper prices push higher for a second straight day and buck the
negative demand implication from U.S. data showing new orders for long-lasting manufactured goods
posted their largest drop in six months in April. [ID:nN25110127]
London Metal Exchange (LME) three-month copper CMCU3 closed up $205 or 2.3 percent at $9,065
In New York, the July COMEX contract HGN1 jumped 9.40 cents to settle at $4.1070 per lb, near
the upper end of its $4.0005 to $4.1270 session range.
The gains helped prices recover more than 6 percent of their value from five-month lows at
$8,504.50 a tonne and $3.8535 a lb on May 12, when heavy liquidation saw losses pile up across many
Copper's mid-week rally was also spurred by news that output from the world's largest mine,
Chile's Escondida, fell 4.2 percent in the first quarter versus a year ago due to maintenance and
lower ore grades. [ID:nN24285277]
"The supply story is certainly part of the strong fundamentals," said Nic Brown, head of
research at Natixis.
"The Chilean copper producers have been struggling for quite some time with declining ore grade
and although there is some new investment in copper, production from major projects is not due to
come on stream until 2012-2013."
Natixis forecast a 165,000 tonne supply deficit this year and a 180,000 tonne deficit in 2012.
Escondida said its output during the first quarter was comprised of 157,976 tonnes of copper
contained in concentrate and 77,294 tonnes of copper cathodes.
Unrest at Chile's fourth largest copper mine, Codelco's El Teniente, only added to the
festering supply-side concerns. [ID:nN25141010]

Zinc, down 9.5 percent so far this year, was enjoying some support, said RBC Capital in a note
titled: "Zinc, the dog of the LME, is having its day."
Three-month zinc CMZN3 touched a three-week high at $2,248 per tonne before closing up $54 at
Apart from having the largest speculative short commitment of the metals, "it has been used as
a hedge for macro copper longs, been a favored short amongst the technical community and not
expected to be in deficit until 2013," RBC said in a note.
"We would expect zinc's outperformance to be short term in nature and that it will follow
broader moves by the complex which continues to see rallies getting sold."
Aluminium CMAL3 went untraded in rings, but was last bid at $2,540 a tonne from Tuesday's
close at $2,505.
The London Metal Exchange is due to take further steps this week to address warehousing
bottlenecks, which critics say have unfairly allowed aluminium to be locked up and helped inflate
prices. [ID:nLDE74N1VF] [ID:nLDE74O0NI]
