METALS-China metals tumble on recession fears amid escalating trade war

SHANGHAI, April 7 (Reuters) - Base metal prices in China tumbled on Monday amid escalating trade war concerns and recession fears, while London metals flipped to a decline after rising on arbitrage trading.

The most-traded copper contract on the Shanghai Futures Exchange (SHFE) dropped 7.0% to 73,640 yuan per metric ton as of 0805 GMT, hovering near its lowest level in over three months since January 3.

SHFE market was closed last Friday for a holiday.

"The retaliatory tariff makes us worry about trade war, which will impede economic growth globally," a metals trader said.

Top metals consumer China hit back on Friday with additional 34% tariffs on all U.S. goods from April 10, after U.S President Donald Trump imposed a 34% tariff on most Chinese goods as part of his sweeping reciprocal tariffs.

Meanwhile, the benchmark three-month copper CMCU3 on the London Metal Exchange (LME) lost 0.5% to $8,733 per ton. Eearlier in the day, copper rose 3% on arbitrage trading.

"When the SHFE market opened in the morning, arbitrage traders actively traded on both SHFE and LME, capitalizing on the price gap to generate profit. Their activity increased market liquidity, which in turn pushed LME metals prices higher," a second base metals trader said.

"Then in the afternoon, the western traders participated in trading, and worries about recession took over," the second trader said.

The traders requested anonymity as they were not authorised to speak to the media.

Arbitrage trading between LME and SHFE happens when traders buy metals on an exchange where it's cheaper and sell it where it's more expensive, profiting from the price difference.

SHFE aluminium SAFcv1 slid 3.7% to 19,685 yuan a ton, zinc SZNcv1 lost 2.2% to 22,625 yuan, lead SPBcv1 fell 3.1% to 16,660 yuan, while nickel SNIcv1 was down 7.5% to 118,640 yuan, tin SSNcv1 fell 8.6% to 267,800 yuan.

Among other metals, LME aluminium CMAL3 lost 1.0% to $2,355 a ton, lead CMPB3 declined 1.5% to $1,878, zinc lost 2.2% to $2,599, tin CMSN3 was down 4.9% at $33,650 and nickel CMNI3 was down 3.1% at $14,305 a ton.
