SHANGHAI, Dec 29 (SMM) — Shanghai base metals mostly cruised lower on Tuesday morning, while their counterparts on the LME rose for the most part as market sentiment was boosted after Trump signed into law the $2.3 trillion pandemic aid and spending package.

Overnight on Wall Street, the three major US stock indexes recorded fresh highs after President Donald Trump signed a $900 billion coronavirus relief package into law. Oil prices declined on Monday as OPEC+ is set to boost output by 500,000 barrels per day in January and Russia supports another increase of the same amount in February.

LME copper is expected to trade between $7,820-7,900/mt today, while SHFE copper between 58,700-59,200 yuan/mt, with spot copper to be traded between discounts of 150 yuan/mt and 70 yuan/mt.

Zinc: Trump signed into law the $2.3 trillion pandemic aid and spending package, averting a partial federal government shutdown that would have started Tuesday, and this, together with optimism over the signing of Brexit trade deals between Britain and the European Union, is likely to boost zinc prices. LME zinc is expected to fluctuate between $2,830-2,880/mt today.

The most-active SHFE 2102 zinc contract shed 0.46% to end at 21,595 yuan/mt in overnight trading, with open interest decreasing 839 lots to 94,261 lots. Zinc concentrate supply was still tight. SMM zinc social inventories increased over last weekend, but consumption in east and south China remained firm.  The February contract is likely to move between 21,500-22,000 yuan/mt today, while spot premiums for domestic 0# Shuangyan will be seen stable at 80-110 yuan/mt against the January contract.

The most-active SHFE 2103 tin contract ended 0.12% weaker at 153,310 yuan/mt in overnight trading, after earlier hitting a one-week high at 154,240 yuan/mt, with open interest increasing 4,037 lots to 25,516 lots. SHFE tin is likely to fluctuate between 150,000-156,000 yuan/mt today.
