Trump shocks markets with scaled-back copper tariff, US prices plunge
WASHINGTON - The United States will impose a 50 per cent tariff on copper pipes and wiring, President Donald Trump said on July 30, but details of the levy fell short of the sweeping restrictions expected and left out copper input materials such as ores, concentrates and cathodes.
The surprise move dragged down US copper prices more than 17 per cent on the Comex exchange and unwound a premium over the London global benchmark that had grown in recent weeks, with shipments diverted there in anticipation of higher domestic prices.
'Markets are now busily repricing refined copper much lower after Trump's epic backflip on his own import tariff policy,' said Mr Tom Price, an analyst at the London brokerage Panmure Liberum.
'Someone must have finally got through to (Mr Trump) that the US economy simply can't afford this new trade-hit.'
Freeport-McMoRan is likely to be among the most harmed by the trimmed tariff, according to RBC Capital Markets, with Hudbay Minerals, Arizona Sonoran and others developing mines in the country also affected.
Mr Trump first teased the tariff in early July, implying that it would apply to all types of the red metal, ranging from cathodes produced by mines and smelters to wiring and other finished products.
Yet in a proclamation released by the White House, the administration said the tariff will apply starting on Aug 1 only to pipes, tubes and other semi-finished copper products, as well as products that copper is heavily used to manufacture, including cable and electrical components.

The move aids manufacturers, but does little to boost the constrained US copper mining industry, which for years has asked Washington for permitting reform or other steps that could fuel growth.
'Copper is being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States,' Mr Trump said in his proclamation.
The tariffs will exclude copper scrap and copper concentrates, mattes, cathodes and anodes, some of the main products of copper mines and smelters.
The move is essentially a boost for Chile and Peru, two of the world's largest copper miners and major suppliers to the United States.
The tariff details sparked a 'massive market surprise,' said Ms Natalie Scott-Gray, senior metals analyst at the consultancy group StoneX, adding that she expects US copper prices to fall further.
Mr Anant Jatia, founder and chief investment officer at Greenland Investment Management, a hedge fund specialising in commodity arbitrage trading, told Reuters he expects London copper prices to surpass US prices in the short term as American inventories build.
More possible
The measure came after a US investigation under Section 232, which Mr Trump ordered in February. The report was delivered to the White House on June 30 by Commerce Secretary Howard Lutnick, according to the proclamation.
Mr Trump said he may still impose further tariffs, and has asked Mr Lutnick to provide an update on the domestic copper market by June 2026. At that point, Mr Trump will evaluate whether to impose a phased universal import duty on refined copper of 15 per cent starting in 2027, and of 30 per cent starting in 2028, he said.
Along with tariffs, the order calls for steps to support the domestic copper industry, including requiring 25 per cent of high-quality scrap produced in the US to also be sold within the country. Freeport, the largest US copper producer, said it would comment after it reviewed Mr Trump's order in detail.
Chile's Codelco, the world's biggest copper producer, praised the exclusion of cathodes as a positive for the company and for Chile, which is the top supplier of refined copper to the US.
BHP, which operates the world's largest copper mine in Chile, and Antofagasta, which ships copper from Chile to the US and wants to build a US copper mine, did not immediately reply to requests for comment. REUTERS

Federal Watchdog Probes Ex-Special Counsel Jack Smith Over Possible Hatch Act Violation
A U.S. federal agency is formally investigating former Special Counsel Jack Smith over whether he violated the Hatch Act while overseeing criminal investigations into former President Donald Trump. The Office of Special Counsel (OSC), an independent agency that monitors federal employee conduct, confirmed the probe on Friday. The move follows a request from Republican Senator Tom Cotton, who accused Smith of acting with political motives to interfere in the 2024 election. Cotton said Smith's actions were designed to damage Trump's campaign, describing him as "a political actor masquerading as a public official" on social media platform X. Smith, a former war crimes prosecutor, led two criminal cases against Trump—one over the alleged mishandling of classified documents and another related to efforts to overturn the 2020 election. Both cases were eventually dropped after Trump's 2024 election win, citing Justice Department policy against prosecuting a sitting president. Although OSC cannot bring criminal charges, it can issue disciplinary recommendations. This investigation adds to a growing list of actions taken by Trump allies against individuals involved in past legal actions against him. Smith resigned in January and issued a report stating that there was sufficient evidence to convict Trump, had the cases gone to trial. Trump has denied any wrongdoing and continues to frame the prosecutions as politically motivated. (With inputs from agencies)

Opec+ makes another large oil output hike in market share push
[LONDON] Opec+ agreed on Sunday (Aug 3) to raise oil production by 547,000 barrels per day for September, the latest in a series of accelerated output hikes to regain market share, as concerns mount over potential supply disruptions linked to Russia. The move marks a full and early reversal of Opec+'s largest tranche of output cuts plus a separate increase in output for the United Arab Emirates amounting to about 2.5 million bpd, or about 2.4 per cent of world demand. Eight Opec+ members held a brief virtual meeting, amid increasing US pressure on India to halt Russian oil purchases – part of Washington's efforts to bring Moscow to the negotiating table for a peace deal with Ukraine. President Donald Trump said he wants this by Aug 8. In a statement after the meeting, Opec+ cited a healthy economy and low stocks as reasons behind its decision. Oil prices have remained elevated even as Opec+ has raised output, with Brent crude closing near US$70 a barrel on Friday, up from a 2025 low of near US$58 in April, supported partly by rising seasonal demand. 'Given fairly strong oil prices at around US$70, it does give Opec+ some confidence about market fundamentals,' said Amrita Sen, co-founder of Energy Aspects, adding that the market structure was also indicating tight stocks. The eight countries are scheduled to meet again on Sep 7, when they may consider reinstating another layer of output cuts totalling around 1.65 million bpd, two Opec+ sources said following Sunday's meeting. Those cuts are currently in place until the end of next year. Opec+ in full includes 10 non-Opec oil producing countries, most notably Russia and Kazakhstan. The group, which pumps about half of the world's oil, had been curtailing production for several years to support oil prices. It reversed course this year in a bid to regain market share, spurred in part by calls from Trump for Opec to ramp up production. BT in your inbox Start and end each day with the latest news stories and analyses delivered straight to your inbox. Sign Up Sign Up The eight began raising output in April with a modest hike of 138,000 bpd, followed by larger-than-planned hikes of 411,000 bpd in May, June and July, 548,000 bpd in August and now 547,000 bpd for September. 'So far the market has been able to absorb very well those additional barrels also due to stockpiliing activity in China,' said Giovanni Staunovo of UBS. 'All eyes will now shift on the Trump decision on Russia this Friday.' As well as the voluntary cut of about 1.65 million bpd from the eight members, Opec+ still has a 2-million-bpd cut across all members, which also expires at the end of 2026. 'Opec+ has passed the first test,' said Jorge Leon of Rystad Energy and a former Opec official, as it has fully reversed its largest cut without crashing prices. 'But the next task will be even harder: deciding if and when to unwind the remaining 1.66 million barrels, all while navigating geopolitical tension and preserving cohesion.' REUTERS

Singapore must stay socially progressive while conserving its cultures: Tharman
Sign up now: Get ST's newsletters delivered to your inbox President Tharman Shanmugaratnam speaking at an event to launch the Encyclopedia of Singapore Tamils on Aug 2. SINGAPORE – Singapore must continue to be a place where cultures can be preserved, including that of its many sub-ethnic groups. At the same time, it must also remain socially progressive, where discrimination in any form is not tolerated, said President Tharman Shanmugaratnam. At an Aug 2 event to launch the Encyclopaedia of Singapore Tamils (EST) , Mr Tharman said the story of the city-state's Tamil community is, in many ways, that of Singapore itself – one of resilience, multicultural integration and also deep social transformation over the country's 60 years of independence. The EST is an online resource that documents the history and contributions of the Tamil community here over the past 200 years, and is a collaboration between the Centre for Singapore Tamil Culture (CSTC) and the National Library Board (NLB). The President noted that in Singapore's early years, migrants from southern India naturally brought with them their caste traditions and practices. As a result, segregation in their social interactions, jobs and living arrangements closely resembled those in their places of origin. For instance, the encyclopaedia records how almost all Indian enclaves here had designated Adi-Dravida zones for those lowest in the caste hierarchy, such as the area between Jalan Besar and Rochor Canal. While attitudes towards caste started to change in the 1930s and 1940s due to reformist movements such as the Tamil Reform Association and the Japanese Occupation, the most profound changes came after Singapore gained independence, said Mr Tharman. A national education system promoted meritocracy regardless of social background, public housing brought people of all communities together, and a growing economy provided opportunities for all, he noted.

But there are still remnants of caste practices among those who have been higher up in the traditional social hierarchy, and a renewed influx of such practices among new immigrants, said Mr Tharman. More also needs to be done to help those who have faced disadvantages passed down through generations, from the time their forefathers arrived here as coolies and indentured labourers, he added. 'As much as we have done away with the most regressive social practices, we have to keep working at this... even as we conserve the core of our cultures, Singapore must remain a socially progressive place, where discrimination of all forms is not tolerated, and inclusivity becomes part of all our lives,' said Mr Tharman. 'It is what makes us as Tamil Singaporeans, and as Indian Singaporeans, distinctive among Indian communities globally.' At the event, CSTC chief executive Arun Mahizhnan said the encyclopaedia addresses a longstanding lack of a comprehensive historical record of Singapore's Tamil community. It currently contains more than 350 entries, covering a range of topics that includes historical events, arts, community organisations, journalism, education, politics and personalities. Being online means it will be accessible to a broad audience both in Singapore and abroad, added Mr Mahizhnan, who is also EST's chief editor. 'Besides preserving our history, it can also inspire younger generations to appreciate and connect with their heritage.' EST deputy editor Sivanantham Neelakandan said the encyclopaedia is meant to be a living document that will continue to grow and 'serve as a lasting testament for generations to come'. The encyclopaedia, published in conjunction with SG60 and NLB's 30th anniversary, can be accessed both in Tamil and English. In his speech, Mr Tharman paid tribute to the generations of Tamils who contributed to Singapore society in areas such as education, women's rights, politics, medicine, law, sports and the arts. He also spotlighted the Tamil community's influence on the city-state's culinary landscape, such as how mee goreng (spicy fried noodles) was created and popularised by the Muslim Chulias of Madras. 'As we celebrate SG60, may this be a reminder of each of our communities' contributions, from the labourers who led the most difficult of lives to the civil servants, educationists, professionals and entrepreneurs, each contributing to making this nation that we treasure,' he said. The event was attended by almost 600 guests, including Minister for Digital Development and Information Josephine Teo and Minister of State for Culture, Community and Youth and Minister of State for Manpower Dinesh Vasu Dash. Following the launch, a roving exhibition will tour four venues across Singapore from August 2025 to February 2026, showcasing key aspects of Singapore's Tamil heritage through interactive panels and displays. The exhibition will highlight lesser-known facts about Tamil publishing, postage stamps, schools and signages.
