LONDON, June 30 (Reuters) - Copper prices fell on Thursday to log their biggest quarterly slump since 2011 as COVID lockdowns in China and slowing economic growth curtailed demand.

Other industrial metals were also headed for their worst quarter in several years, down between 20% and 40%.

Many analysts fear further declines in the near term, as central banks push ahead with rapid interest rate hikes that will stifle growth. 

"We still see metals falling as a recession in the U.S. is fully priced in," said Commerzbank analyst Daniel Briesemann. 

Benchmark copper on the London Metal Exchange (LME) fell 1.6% to $8,265.50 a tonne as of 1604 GMT, down around 20.3% since the start of April.

Copper fell 19.8% in the first quarter of 2020 as COVID-19 spread worldwide, which was its biggest quarterly drop since 2011.

Briesemann said copper could slip to as low as $7,000-$7,500 in the third quarter, but prices should rise towards the year-end.

MARKETS: Global stock markets have suffered the worst first half of a year on record. 

DOLLAR: The dollar is set for its biggest quarterly gain since 2016, making metals priced in the currency costlier for non-U.S. buyers.

CHINA: Chinese factory activity rose slightly in June after three months of contraction caused by COVID lockdowns.

JAPAN: Japan's manufacturing output saw its biggest monthly drop in two years in May.
