Copper futures have hit a record high, raising the possibility of spillover beyond commodities into the cryptocurrency market. Some market analysts point to a pattern in which copper strength was followed months later by an altcoin rally, and say the latest rise could be a signal that risk appetite is returning in the crypto market.

According to blockchain outlet BeInCrypto on May 13 local time, copper futures rose to $6.69 per pound, marking a record. Copper futures are up about 16.98 percent so far this year, beating gold futures, which have gained 8.38 percent over the same period.

The market points to a global supply shortage and a surge in industrial demand as key drivers of the rise. With data centres, artificial intelligence (AI) infrastructure, electric-vehicle plants and power-grid expansion all advancing at the same time, demand for copper is rising rapidly, analysts say.

On the supply side, production disruptions at major mines are adding to the strain. Market analysis platform The Kobeissi Letter noted that copper prices have risen more than 40 percent over the past 12 months.

JPMorgan Chase analysed that Indonesia's Grasberg mine has yet to return to normal operating levels after a large-scale landslide in September last year. Chile's Quebrada Blanca mine also lowered its production guidance due to operational issues, further intensifying global supply pressure, it said.

Demand pressure is also strong. AI data centres, electric vehicles and power grids all require large-scale copper wiring. China’s April exports rose 14 percent from a year earlier, and much of the increase is said to have come from shipments of clean-technology products. These industries also use a high proportion of copper.

In the cryptocurrency market, some interpret this as a leading signal for an altcoin rise. Crypto analyst Ash Crypto argued that in 2017 and 2021, copper price strength was followed about 6 months later by a surge in altcoins.

He analysed that the ongoing expansion of global infrastructure investment could ultimately be linked to crypto infrastructure and inflows of speculative funds. "Altcoins have not moved yet and copper has already moved," he said, adding that the key in this cycle is not whether altcoins follow but how long the time lag will be.

Crypto market analyst Michaël van de Poppe also said the copper-to-gold ratio chart and the ether-to-bitcoin chart show similar moves. He argued that copper ending about 5 years of weakness and turning strong against gold is an important signal suggesting a recovery in risk appetite and strength in the altcoin market.

Van de Poppe said the current flow looks similar to past cycles, as most altcoins have remained weak against bitcoin over the past several years. He said he is placing more weight on the possibility of further gains over the next 1 to 2 months than on a sharp short-term correction.

The market also notes that the link between copper prices and the altcoin market is still based on historical patterns and interpretations by some analysts. The key confirmed facts so far are that copper prices hit a record amid supply shortages and expanding industrial demand, and that some market participants are tying that to a recovery in risk appetite and the possibility of altcoin strength.

As a result, whether the strength in copper will actually lead to price rises in major altcoins, including ether, is emerging as the market’s next point to watch.
