Trump's Copper Tariff Decision Hangs in the Balance: Three Scenarios to Shape the Global Copper Market

The Commerce Department's copper tariff review is due by late June, and Trump's call — tax, exempt, or delay — will redirect global copper trade flows and reset the price structure, with different winners under each path.

01

Why has this been hanging for nearly a year?

Last July Trump signed a proclamation requiring the Commerce Department to complete a national-security review before deciding on phased refined-copper tariffs — starting at 15%, set for January 2027.
The report still hasn't landed; it is expected by late June. This means → until it drops, no one knows whether tariffs will be imposed, scrapped, or kicked further down the road.
In the meantime, tariff expectations have repeatedly pushed New York Comex copper futures above London's LME price, handing arbitrage traders outsized profits.

Scenario one: tariffs land — who wins, who loses?

Morgan Stanley puts the probability at 43%: a 15% tariff from January 2027, with Trump likely signaling a rise to 30% in 2028.
If it happens, copper will flood into Comex warehouses from Europe, Asia, and Africa ahead of the deadline, pushing prices higher.
In plain terms = producers with U.S. operations benefit most — Jefferies names Freeport-McMoRan, Rio Tinto, Hudbay Minerals, and Ivanhoe Electric.
The pro-tariff argument: copper's strategic importance now rivals oil, and because the tariff rests on an independent national-security review, it is legally harder to challenge in court than other Trump-era duties.

Scenario two: no tariff — how does the market reverse?

If Trump rules copper out, the Comex premium that drives arbitrage vanishes instantly. This means → copper previously shipped into the U.S. could flow back out, easing supply tightness elsewhere and pushing global prices down.
Traders would move metal from Comex warehouses to nearby LME facilities first, unwinding positions built over the past year.
Put simply = every trade that bet on tariffs landing would need to be reversed — expect sharp short-term price swings.

Scenario three: delay — who is betting on this path?

BNP Paribas expects the decision to be postponed, and sees a possible outcome where direct supply arrangements replace tariffs altogether.
The bank's senior metals strategist David Wilson notes: "Companies that lobbied against tariffs last year are still lobbying actively and hard. Taxing a raw material makes no logical sense — it cannot conjure new supply out of thin air."
This reflects a core tension: copper-product manufacturers warn costs will be passed to customers, while the reshoring camp argues the U.S. cannot depend on foreign copper.

What is the real bottom line of this standoff?

Copper is the critical metal for grid buildouts and data-center expansion — its strategic status is rising fast.
The tariff decision will be a clear test of the Trump economic team's priorities: lower costs for manufacturers, or push raw-material production back to U.S. soil — two goals that pull in opposite directions.
Amy O'Shaughnessy of the Copper & Brass Fabricators Council sums up the state of play: "There is no indication yet which way the government is leaning."
