July 20 (Reuters) - Shanghai copper fell on Tuesday to its lowest in nearly a month, as a surge in coronavirus cases threatened the outlook for a global economic recovery.
The most-traded August copper contract on the Shanghai Futures Exchange fell as much as 2.3% to 67,400 yuan ($10,393.86) a tonne, its lowest since June 23, before edging up to close at 68,130 yuan a tonne, still down 1.2%.
Three-month copper on the London Metal Exchange rose 0.6% to $9,277 a tonne by 0705 GMT, rebounding from a 2.2% drop in the previous session to a four-week low.
Sentiment for copper, often used as a gauge of global economic health, was hit by worries that rising cases of the highly contagious Delta variant around the world could slow a nascent economic recovery.
“It’s risk-off from U.S. selling and equities melting down. Recovery is fragile as it’s now threatened by the Delta variant spreading across the world and now going mainstream in the United States,” said a Singapore-based metals trader.
