Although a firm dollar limited the gains, copper prices in London remained stable on Wednesday, supported by an improvement in risk appetite in financial markets following the latest tariff break by US President Donald Trump.

Three-month copper on the London Metal Exchange maintained its level at $9,593.5 per metric ton at 02:14 GMT. The most traded copper contract on the Shanghai Futures Exchange (SHFE) rose by 0.1% to 78,390 yuan ($10,886.29) per ton. According to Kelvin Wong, senior market analyst for the Asia-Pacific region at OANDA, “Over the past two weeks, copper prices have moved in line with the general feeling on global stock markets. Business optimism has boosted the American stock market and has also had an impact on copper prices.”

The global refined copper market posted a surplus of 17,000 metric tons in March, compared to a surplus of 180,000 metric tons in February, the International Copper Study Group (ICSG) said in its latest monthly bulletin.
