LONDON: Copper prices slid on Friday to their lowest in nearly two months on a strong dollar and fears of recession-hit metals demand after further increases to interest rates.

Three-month copper on the London Metal Exchange (LME) had dropped 3.4% to $7,420 a tonne by 1500 GMT to its weakest since July 25. “The macro outlook is hitting industrial metals quite hard. The main worry is that central banks will allow the economy to slip into recession in an attempt to bring inflation under control,” said Ole Hansen, head of commodity strategy at Saxo Bank in Copenhagen. Now copper has broken below $7,475 a tonne, traders will be eyeing the $6,955 20-month low touched on July 15, he added.

Other risky assets were swept up in the scramble to sell, with equities hitting two-year lows after investors realised that aggressive increases to US interest rates are likely to continue for longer than previously expected.

The dollar index climbed to its highest in two decades, making commodities priced in the US currency more expensive for buyers using other currencies. Tight supply and rising demand in China, however, has supported metals prices recently.

“Power grid and new energy sectors have raised their orders for copper products,” one China-based copper producer said. Physical markets also registered increased demand as producers looked to replenish stocks ahead of China’s National Day holiday over Oct. 1-7. But those upbeat elements were swept away by the broader economic concerns, with rising LME copper inventories also dampening the mood after they shot up by a fifth over the past week.

Also weighing on aluminium were worries that increasing flows of Russian material would depress prices. LME aluminium fell 3% to $2,162 a tonne, the weakest since March 2021, while zinc eased by 3.2% to $3,007 and lead gave up 2.2% to $1,810, both of which were the lowest in about two months. Nickel shed 4.3% to $23,510 and tin tumbled 6% to $20,355 a tonne.
