LONDON: Copper prices jumped to their highest since 2012 on Monday as investors continued their buying spree on concerns over rising inflation and stronger than expected demand in top metals consumer China.

Three-month copper on the London Metal Exchange (LME) was up 0.2% at $8,349.50 a tonne by 1130 GMT after touching $8,406, its highest since September 2012.

"There's a very, very strong focus on reflation and there's also a feeling that Chinese demand is not going to be as weak as in previous new years because travel restrictions are keeping more production capacity open," said Ole Hansen, head of commodity strategy at Saxo Bank in Copenhagen.

Chinese markets are closed for the Lunar New Year holiday until Feb. 17, but factories are maintaining higher operating rates than usual for the holiday period.

Hansen said the technical picture for copper was bullish because of an uptrend channel that has persisted since last March.

"The upper bound of that channel is $8,700, so there's another $300 and that's going to be the next target for copper," he said.

ANZ has set a 12-month target price of $9,000 a tonne for the metal often used as a gauge of global economic health.

"With environmental policies accelerating the use of copper, we see the market remaining tight this year," said Daniel Hynes, senior commodity strategist at ANZ.

Cash LME copper's premium to the three-month contract rose to $20.25 a tonne, its highest since last September, indicating tight near-term availability of material.

LME inventories have slid 44% over the past two months.

Nickel rose as much as 1.2% to $18,785 a tonne, its loftiest since September 2019, on the strong demand outlook for a key material in producing electric vehicle batteries. It the pared gains to $18,600, up 0.2%.

LME aluminium shed 0.6% to $2,077 a tonne and zinc lost 0.4% to $2,822.50.

Lead rose 0.3% to $2,125 after touching its strongest since November while tin advanced 0.2% to $23,700, having hit its strongest since March 2013.
