METALS-Copper up, but growth fears subdue sentiment

By Pratima Desai

LONDON, March 16 (Reuters) - Copper prices rose on Monday as a softer dollar triggered profit-taking, but sentiment was subdued as surging oil prices due to the conflict in the Middle East fuelled fears about inflation and global growth.

An outage on the London Metal Exchange's electronic trading system left traders without access to prices for nearly three hours.

Benchmark copper CMCU3 on the London Metal Exchange was up 0.9% at $12,886 a metric ton at 1805 GMT. It had fallen as much as 0.9% earlier in the session.

Investors see copper as a gauge of economic health due to its use in the power and construction industries.

A lower U.S. currency makes dollar-denominated metals cheaper for holders of other currencies.

Oil prices LCOc1, CLc1 have jumped more than 40% as the U.S.-Israeli war on Iran continued to disrupt oil production and shipping in the Middle East.

High energy prices damage growth by pushing up costs for households and businesses, squeezing spending and profits. They also stoke inflation and force central banks to keep policy tight.

Stronger economic data from China helped support sentiment. China's industrial output rose 6.3% year-on-year in January-February and fixed asset investment rose 1.8%. Both readings beat estimates.

However, rising copper stocks in warehouses monitored by the Shanghai Futures Exchange suggest subdued demand in China, the world's largest consumer of industrial metals.

Copper inventories in LME-approved warehouses have also climbed.

Elsewhere, aluminium is expected to hold firm due to shortages created by disruptions to Middle East supply and the closure of the Strait of Hormuz.

A prolonged U.S.-Israeli war on Iran could create severe shortages of aluminium used in the transport, construction and packaging industries.

The Middle East produces roughly seven million tons of aluminium annually, or about 9% of the global total.

Problems with supplies of power - vital for the aluminium smelting process - have prompted production curtailment.

Aluminium Bahrain ALBA.BH was the latest, initiating a shutdown of three aluminium smelting lines on Sunday, accounting for 19% of its capacity.

Aluminium CMAL3 retreated 0.9% to $3,407, zinc CMZN3 lost 0.5% to $3,278, lead CMPB3 rose 0.5% to $1,918, tin CMSN3 gained 1.9% to $47,955 and nickel CMNI3 rose 1.1% to $17,450 a ton.
