Zinc hits three-week high after strong China imports but copper under pressure

LONDON — Zinc hit a three-week peak on Tuesday after imports of the metal into top consumer China rose, underlining potential shortages, but copper was under pressure on indications of healthy supply.

Imports of refined zinc to China grew 21% in April to 47,469 tons annually while shipments of ore and concentrates jumped 44%, customs data showed.

Industry sources said that China is stepping up imports as dwindling global supplies of concentrate following mine closures hit local output of the metal, used to galvanize steel.

“Those import numbers showing that China’s importing more in April could be evidence showing things are tightening up in China, which is the biggest consumer,” said Robin Bhar, head of metals research at Societe Generale.

China’s copper imports, however, fell 41%, partly due to tighter credit. “That reflects that the import arb ( arbitrage) was essentially closed in the first quarter and has only fleetingly been opened from time to time,” Mr. Bhar added.

London Metal Exchange (LME) benchmark zinc closed up 1% at $ 2,658 a ton after touching $ 2,669, the highest since May 2, while LME three-month copper closed 0.20% lower at $5,714 after dipping to an intraday low of $5,666.

The global world refined copper market showed a 93,000 tons surplus in February, compared with a 55,000 tons surplus in January, the International Copper Study Group said in its latest monthly bulletin.

LME lead rose 0.20% to end at $2,069.

On-warrant LME lead stocks, those not earmarked for delivery, jumped by a quarter and nearby tightness in lead spreads dissolved.

The cash over the threemonth contract flipped to a $ 23.25 discount, the widest since July 2014, after having been at a $34.50 premium in late April.

LME aluminum shed 0.30% to finish at $1,943 after Chinese exports of semi-finished products rose 8.10% in April to 380,000 tons.

“China April exports rose… in further signs that the much discussed potential capacity cuts are yet to take hold,” Alastair Munro at broker Marex Spectron said in a note.

The LME price retreated by 0.50% to close at $9,345 after Chinese ore imports surged by 48%.

“Recovering ore exports from the Philippines were responsible for the bulk the April rebound,” Trace Xian Liao at Citi said in a note.

Tin prices finished up 0.10% at $20,500. —
