SINGAPORE, June 28 (Reuters) - Copper prices edged higher on Friday but were on track for their weakest quarterly performance since the end of 2015, weighed down by demand fears from the U.S.-China trade war.
Benchmark three-month copper prices rose 0.1% to $5,995 a tonne as of 0737 GMT. Prices have fallen 7.5% so far in the second quarter, on track for their biggest drop since the quarter ended December 2015.
The poor performance follows a big fall in May when U.S.-China trade tension deepened and copper prices posted their steepest monthly decline in three-and-a-half years.
The most-traded copper contract on the Shanghai Futures Exchange (ShFE) ended down 0.2% on Friday at 47,010 yuan ($6,847.58) a tonne.
Investors are waiting for a meeting between U.S. President Donald Trump and Chinese President Xi Jinping scheduled on Saturday in Japan, hoping for news about any resolution to a prolonged trade war.
“The trade war is the single biggest factor. No one has any idea when it’s going to end and how. And we’re being bounced around by news flows and tweets and rumours. There’s not a lot more that people can do,” said Guy Wolf of Marex Spectron.
“If this trade war situation gets resolved, and almost doesn’t really matter how, even if there are tariffs, just the certainty of knowing what environment you’re going to be in...is going to be enough for people to be able to do things.”
Copper is widely used in the industrial and manufacturing sectors and its prices are often considered as an indicator of the health of the global economy.
