London copper futures closed higher on the back of a weaker dollar

The Wall Street Journal's dollar index was last down 0.
33 percent at 86.
13, making dollar-denominated copper cheaper
for holders of other currencies.

European stocks and crude oil futures also rebounded after the assassination of a pro-Remain lawmaker and the UK suspended canvassing for the Brexit referendum
.
Analysts said that market sentiment has been up and down recently, and the next few days will focus on the Brexit referendum
.

Market sentiment has become cautious after industry insiders said copper inventories in LME's registered warehouses could rise by about
50 percent next month as copper was diverted out of China.
Participants at the LME Asia Annual Meeting said rising inventories could weigh on copper prices in the short term, while new mine supply also worries
the long-term outlook.

Industry sources estimate that 150,000 to 200,000 tonnes of copper will be shipped to warehouses in South Korea, Singapore and possibly Taiwan, except for a small amount of copper purchased in the past week when copper prices fell below $4,500 a tonne
.
As a result, LME copper stocks are expected to rise to around 300,000 tonnes, the highest since October last year, after surging by more than 40,000 tonnes earlier this month, the largest delivery in more than 10 years
.

At 16:00 London time on June 17 (00:00 Beijing time on June 18), three-month copper on the London Metal Exchange (LME) closed up 0.
3% at $4,552 a tonne, rebounding slightly after falling more than 2% last day, with intraday volatility ranging just $
