METALS-Signs of tight supply push copper and zinc towards weekly gains
Supply shortages were also powering zinc towards a 4 percent weekly gain -- its biggest since September.
Benchmark copper on the London Metal Exchange was up 0.4 percent at $6,209.50 a tonne at 1559 GMT. Prices rallied after news that Chinese smelter Jiangxi Copper and miner Antofagasta had agreed lower treatment and refining charges for 2019, said ING analyst Warren Patterson. "This is showing that either there is a tightening in concentrate supply or too much spare smelting capacity in China. I think it's a mixture of the two," he said.
Metals received a further boost when the U.S. dollar weakened after Federal Reserve officials appeared to question the pace of interest rate rises and from strong U.S. manufacturing data. A weaker dollar makes metals cheaper for buyers who hold other currencies.
But while the fundamentals were good for copper, uncertainty about U.S.-China trade talks were weighing on prices, Patterson added.
COPPER STOCKS: Headline copper inventories in LME-registered warehouses fell by 5,425 tonnes to 161,025 tonnes, nearing last month's 10-year low of 136,675 tonnes.
SPREAD: Another signal of tight supply is the premium of cash copper over the three-month contract , which has drifted from a near four-year high of $47 last month to $20.50 but is still far above recent norms. TECHNICALS: Copper was holding above its technically important 50-day and 100-day moving averages around $6,160-$6,165.
U.S.-CHINA TRADE TALKS: A senior White House official told Reuters a written response sent this week by China to U.S. demands for trade reforms was unlikely to trigger a breakthrough at talks. Worries that rising tariffs could damage China's economy have helped to push industrial metals prices sharply lower in recent months. China is the world's largest consumer of metals. ZINC: Benchmark LME zinc was up 1.5 percent on the day at $2,617 a tonne and up 3.7 percent this week, with stockpiles in the LME's warehouse system falling to a 10-1/2-year low of 125,400 tonnes. SPREAD: The premium of cash zinc over three-month metal has surged to $75.75, the highest since October last year, from a discount of more than $20 two months ago, suggesting a shortage of available material.
OTHER METALS: LME aluminium was up 0.3 percent at $1,935 a tonne, nickel was 1.4 percent higher at $11,415, lead had gained 3.1 percent to $1,990 and tin was flat at $19,385.
