Switching off plants: Chinese copper smelters grapple with margin collapse
By Amy Lv and Lewis Jackson
BEIJING (Reuters) - Major copper smelters across top consumer China have kicked off equipment maintenance in March, traditionally a peak demand period, in a bid to stem losses from a worsening feedstock shortage that is hammering margins, industry insiders said.
Shutting down plants in what is traditionally one of the busiest times of the year highlights how much pain the scarcity of copper concentrate is causing refiners, a problem compounded by smelting overcapacity that has sparked fierce competition for the raw material and sent treatment fees below zero.
Roughly 980,000 metric tons of smelting capacity, or 8% of China's total last year, is set for maintenance in March, Hongyuan Futures said in a note. Three analysts and a smelter manager told Reuters this was an unusually high amount compared to previous years.
Staff at three large smelters confirmed to Reuters they began equipment maintenance in March. Another operator, Tongling Nonferrous Metals Group, which accounted for 13.5% of China's refined copper output in 2023, started month-long maintenance on some smelting equipment in early March, according to two sources.
Production cuts can be sensitive in China, where many smelters are important contributors to regional economies, but as in many industries, from steel to oil refining, the sector is plagued by overcapacity as operators chase market share.
The overcapacity in China, the world's largest supplier of the refined metal used in wiring, machinery and new energy technologies, is contributing to a global imbalance in the copper smelting industry.
By shutting equipment for maintenance, smelters hope to cut consumption of copper concentrate, ease the concentrate shortfall and stop processing fees from sliding even further, analysts said.
Eight analysts and smelters who spoke to did so on condition of anonymity given they are not authorised to speak to media.
Tongling did not respond to Reuters' request for comment.
The industry's difficulties put a spotlight on the March 31 quarterly meeting of the China Smelters Purchase Team (CSPT), where measures including production cuts are set to be discussed, sources with knowledge of the matter said.
"There is a significant risk of large-scale output cuts among Chinese smelters this year," said Patricia Barreto, senior analyst at S&P Global Commodity Insights.
If Chinese smelters jointly agree a production cut, refined copper output this year will likely fall, which could lead China to import more, analysts said.
UNUSUAL TIMING
Widespread maintenance is unusual in March, when smelters historically benefit from a surge in demand after the Lunar New Year holiday before undergoing maintenance in April or May.
Supply of copper concentrate has been tight since late 2023 due to disruptions at major mines including First Quantum's Cobre mine in Panama as well as smelter capacity expansion.
That overcapacity, which continues to grow, is increasing demand for globally scarce concentrate.
Analysts at Antaike and Shanghai Metals Market have lowered forecasts for copper concentrate output growth this year due to downward revisions from producers, according to research notes from Citi.
Some smelters are operating at a loss, and not just in China.
Glencore's Pasar smelter in the Philippines was put on care and maintenance in February. Japan's smelters, while bunkering down for tough times, may fare better as they are more diversified than China's and have long-term supply contracts.
Treatment and refining charges (TC/RCs), a key revenue source, have been negative since December 20, meaning smelters must pay miners or traders to turn concentrate into refined metal, instead of the other way around.
Fastmarkets copper concentrates TC/RC index plunged to a record low of -$26.5 per ton and -2.65 cents per pound on March 7.
"The situation is much tougher this year, as last year smelters could make some money thanks to better prices for the long-term contract, but you are suffering losses in whatever situation right now," said a manager at a Chinese smelter.
"The only difference is whether you are losing more money or less money," the manager added, saying losses were as much as 3,000 yuan ($414.47) per ton of refined copper for spot cargoes.
Four analysts estimated losses at between 1,000 yuan and 2,000 yuan per ton.

Rubio vowed to revoke Chinese student visas. Trump now says Chinese students are welcome
In a potential pullback after U.S. officials said two weeks ago that they would 'aggressively' revoke visas for Chinese students enrolled at U.S. universities and increase vetting of student visa applicants, President Trump said Wednesday that he had come to an agreement with China on students 'using our colleges and universities.' The president offered no details on the students in the announcement posted to his Truth Social platform as part of a brief outline of a trade deal with China that he said was pending approval by each side. But the decision appeared to relax a clampdown on America's second-largest international student group that has been under increased scrutiny since May 28, when Secretary of State Marco Rubio suggested the U.S. would broadly revoke Chinese student visas and target individuals with ties to the Chinese Communist Party or who studied unnamed 'critical fields.' On Wednesday, Trump said that having Chinese students at U.S schools 'has always been good with me!' 'Our deal with China is done, subject to final approval with President Xi and me. Full magnets, and any necessary rare earths, will be supplied, up front, by China. Likewise, we will provide to China what was agreed to, including Chinese students using our colleges and universities (which has always been good with me!). We are getting a total of 55% tariffs, China is getting 10%. Relationship is excellent! Thank you for your attention to this matter!' Trump said in his all-caps post. The State Department did not respond to a request for clarification on the visa matter, including the question of whether Rubio's comments still applied. The May policy to aggressively cancel Chinese student visas has roiled higher education nationally and in California. Universities depend on the full tuition fees paid by international students and see Chinese and other foreign students as integral to their academic operations and missions to foster diverse campuses. The May 28 Rubio announcement — and now the potential relaxing of it — has exacerbated growing uncertainty at universities, which have been dealt a barrage of actions under Trump, including grant cancellations, federal investigations into alleged antisemitism and investigations into admissions policies. International students have especially been in the crosshairs. There have been thousands of student visa cancellations over the spring for violations as minor as speeding tickets and attempted deportations of pro-Palestinian college activists who are international students. There is a pause of new student visa application appointments while the State Department increases security vetting procedures, including probing social media profiles for pro-Palestinian language and imagery. Trump's new travel ban, which went into place Monday, has also led some universities to advise incoming students from countries on the list to defer enrollment. Of the 1.1 million foreign students enrolled at U.S. universities, roughly 277,000 are Chinese — second only to Indians. The 51,000 Chinese nationals in California make up more than a third of the state's nearly 141,000 foreign students. The University of California has 17,832 Chinese students across all of its campuses. Locally, USC has nearly 6,000 and UCLA has 2,208. A UC spokesperson declined to comment on Trump's social media post and pointed The Times to the university's prior statement on Chinese student visa restrictions that said it was 'concerned about the U.S. State Department's announcement to revoke visas of Chinese students.' 'Chinese students, as well as all our international students, scholars, faculty and staff, are vital members of our university community and contribute greatly to our research, teaching, patient care and public service mission,' the statement said. A USC spokesperson did not respond to a request for comment Wednesday. While there are no data pointing to widespread security concerns over Chinese students and scholars, there have been incidents in recent years. This week, the U.S. said it arrested a Chinese scientist who was arriving in Detroit to pursue research at the University of Michigan. The scientist, from University of Science and Technology in Wuhan, is accused of illegally smuggling biological material related to worms that require a government permit. In an interview, Rep. Mark Takano (D-Riverside), a member of the Republican-led House Committee on Education and the Workforce, called the potential Trump shift on Chinese student visas an example of 'TACO,' a phrase some Democrats are using to say 'Trump always chickens out,' reflecting the president's policy shifts. Republicans have argued that the president's shifts are a negotiation strength. 'In allowing Chinese students to come here, it's part of the importance of the United States being a draw for students from everywhere,' Takano said. 'But his overreach, his interference in the operations of universities ... endangers the higher education enterprise of America.' There is also political value to the U.S. in having Chinese students here, experts said. 'For the United States, bringing Chinese students [here] isn't just about educating them in subjects like math and science — it is about educating them in American values, like democracy and freedom of speech,' said Emily Baum, an associate professor of modern Chinese history at UC Irvine. 'And the expectation is that either they will stay in the United States because they enjoy life here or take those values back to China and influence the political system.' It could be that some Chinese students are turned off by the vacillations of the Trump administration and decide to stay in China for university, one expert added. Gaurav Khanna, an associate professor of economics at UC San Diego, said that around the year 2000, China began a major campaign to build new universities. Within about half a decade, it had doubled the number of institutions in the country, he said. 'They invested heavily,' Khanna said. 'In some ways, they are well-suited to say, 'Hey, don't risk your future going to a second-tier American university. Why don't you stay back here in China and go to this really good university where ... there is funding for research?''

Wall Street's rally stalls as US stocks dip for their 1st loss in 4 days
NEW YORK — Wall Street's rally stalled on Wednesday after U.S. stocks climbed back within 2% of their all-time high. The Standard & Poor's 500 fell 0.3% for its first loss in four days. The Dow Jones Industrial Average was virtually unchanged after edging down by 1 point, and the Nasdaq composite slipped 0.5%. Several Big Tech stocks led the way lower, and a 1.9% drop for Apple was the heaviest weight on the market. It's been listless this week after unveiling several modest upcoming changes to the software that runs its devices. The action was stronger in the bond market, where Treasury yields eased after a report suggested President Trump's tariffs are not pushing inflation much higher, at least not yet. U.S. consumers had to pay prices for food, gasoline and other costs of living that were 2.4% higher overall in May than a year earlier. That was up from April's 2.3% inflation rate, but it wasn't as bad as the 2.5% that Wall Street was expecting. A fear has been that Trump's wide-ranging tariffs could ignite an acceleration in inflation, just when it had seemed to get nearly all the way back to the Federal Reserve's 2% target from more than 9% three summers ago. It hasn't happened, though economists warn it may take months more to feel the full effect of Trump's tariffs. 'Another month goes by with little evidence of tariffs, but the longer-term inflation challenge they pose remain,' according to Ellen Zentner, chief economic strategist for Morgan Stanley Wealth Management. Financial markets also had only modest reactions to the conclusion of two days of trade talks between the United States and China in London. Trump said Wednesday that China will supply rare-earth minerals and magnets to the United States, while his government will allow Chinese students into U.S. universities in a deal that still needs an agreement by him and by China's leader. Trump also said that 'President XI and I are going to work closely together to open up China to American Trade. This would be a great WIN for both countries!!!' Investors are still hoping for a more sweeping trade deal that would ease tensions between the world's two largest economies. Hopes for such deals between the United States and countries around the world have been one of the main reasons the S&P 500 has charged nearly all the way back to its all-time high after dropping roughly 20% below a couple months ago. Without them, the fear is that Trump's high tariffs could drive the economy into a recession while pushing inflation higher. The S&P 500 is now sitting 2% below its record. On Wall Street, Chewy dropped 11% after the seller of pet supplies reported a weaker profit for the latest quarter than analysts had forecast. Expectations were high after its stock had already rallied nearly 37% coming into the day for the year so far. Tesla swung between gains and losses before finishing with a rise of 0.1% to continue its shaky run. It's been recovering much of its big losses taken last week after Elon Musk's relationship with Trump imploded, which in turn raised fears about a loss of business for the electric-vehicle company. Musk on Wednesday backed away from some of his earlier comments and said they went 'too far.' All told, the S&P 500 fell 16.57 points to 6,022.24. The Dow Jones Industrial Average slipped 1.10 to 42,865.77, and the Nasdaq composite sank 99.11 to 19,615.88. In the bond market, the yield on the 10-year Treasury eased to 4.41% from 4.47% late Tuesday. Shorter-term yields, which more closely track expectations for what the Fed will do with overnight interest rates, fell more. Wednesday's better-than-expected reading on inflation raised expectations along Wall Street that the Fed could cut its main interest rate at least twice by the end of the year. The Fed has been keeping interest rates steady so far this year, going on pause after cutting rates at the end of last year. It has been waiting to see how much Trump's tariffs raise inflation because cutting interest rates could push inflation up even more, in addition to giving the economy a boost. 'The Fed could be justified in doing some preemptive rate cuts,' said Brian Jacobsen, chief economist at Annex Wealth Management. 'They were afraid that inflation would rise before growth would slow, but the script has been flipped and they will likely change their tune.' In stock markets abroad, indexes fell across much of Europe after rising in Asia. South Korea's Kospi was one of the best performers and jumped 1.2%. Choe writes for the Associated Press. AP Business Writer Yuri Kageyama contributed.

Hegseth wavers on Russia sanctions, says US should not use ‘every tool' to end Ukraine invasion
WASHINGTON — Defense Secretary Pete Hegseth resisted senators' efforts to secure his support for a bipartisan bill that would sanction Russia for its war on Ukraine, telling an Appropriations subcommittee Wednesday that the US should not use 'every tool at our disposal' to pressure Moscow to stop its assault. Asked by Sen. Chris Coons (D-Del.) whether Washington 'should use every tool it has at its disposal, including additional sanctions, to pressure Russia to come to the table to negotiate a just and lasting peace for the war in Ukraine,' Hegseth demurred. 'Senator, every tool at our disposal? No,' he said. 'We have a lot of tools in a lot of places.' 'We should be pursuing a cease-fire and a negotiated resolution to the war in Ukraine at any cost,' Coons responded. ''Peace through strength' means actually using our strength, continuing to support Ukraine, and securing a lasting peace. [Vladimir] Putin will only stop when we stop him.' 4 Defense Secretary Pete Hegseth testified Wednesday at a Senate Appropriations Committee hearing. REUTERS Prior to questioning Hegseth, Coons had talked up Sen. Lindsey Graham (R-SC) and Sen. Richard Blumenthal's (D-Conn.) pending bill to further sanction Russia for its continued resistance to peace in Ukraine. The legislation, backed by 80 senators, would impose sanctions on key Russian officials and economic sectors — and, critically, penalize foreign nations that do business with Moscow. Graham later followed up, urging Hegseth and the administration 'to use that tool to get the attention of China and India.' 'China buys — and India buys — 70% of Russia's oil … If they stop buying cheap Russian oil tomorrow, would that grind Putin's war machine to a halt?' Graham asked, later adding: 'We have an ability, through legislation, to get China and India's attention [and say] that if you keep buying cheap Russian oil to empower Putin to kill Ukrainian children, you're going to lose access to our markets. 'We're not going to evict every Russian from Ukraine, I'm a practical guy,' Graham added. 'But we got to end this war so we don't entice China to take Taiwan, and we don't encourage Iran to think we're just all talk [about] stopping their nuclear ambitions.' 4 Sen. Lindsey Graham (R-S.C.) questions Secretary of Defense Pete Hegseth during a Senate Committee on Appropriations subcommittee hearing to examine proposed budget estimates for fiscal year 2026 for the Department of Defense. AP On Friday, the Wall Street Journal reported that the White House was quietly pushing Graham to water down the bill by allowing waivers to exempt certain people and entities from sanctions and to 'remove the mandatory nature' of the legislation. A White House official told the outlet that the Constitution 'vests the president with the authority to conduct diplomacy with foreign nations.' 'Any sanction package must provide complete flexibility for the president to continue to pursue his desired foreign policy,' they added. Hegseth did admit Wednesday that Russia is the 'aggressor' in Ukraine and that Chinese President Xi Jinping wants Moscow to 'win' the conflict. However, the secretary declined to answer Sen. Mitch McConnell's (R-Ky.) question about 'which side' he wanted to win the war. 'As we've said time and time again, this president is committed to peace in that conflict,' Hegseth said. 'Ultimately, peace serves our national interests, and we think the interests of both parties, even if that outcome will not be preferable to many in this room and many in our country.' 4 Defense Secretary Pete Hegseth (R) greets Chairman of the Joint Chiefs of Staff Air Force Gen. Dan Caine before testifying during a hearing with the Senate Appropriations Committee on June 11. Getty Images McConnell pushed further, noting that the Russians 'don't seem to be too interested' in peace talks. The former Senate GOP leader also alleged that NATO partners increasing their defense spending at Trump's behest are now wondering 'whether we're in the midst of brokering what appears to be allowing the Russians to define victory.' 'I think victory is defined by the people that have to live there, the Ukrainians,' he said. 'And I don't think they're going to ever conclude that victory means basically adopting the Russian views on all this. ' Hegseth responded that 'no one's adopting views,' but added that the upcoming National Defense Authorization Act does not include funding of weapons for Ukraine because 'the budget reflects the reality that Europe needs to step up more for the defense of its own continent, and President Trump deserves the credit for that.' 4 Ranking member Sen. Chris Coons (D-Del.) speaks with subcommittee Chairman Sen. Mitch McConnell (R-KY) during a hearing with the Senate Appropriations Committee on June 11, 2025. Getty Images McConnell agreed, noting that he had 'the same complaints' about the Biden administration not pushing hard enough for Europe to fund Ukraine's defense. Still, the Kentuckian insisted that by not standing foursquare behind the Kyiv government, 'it seems to me pretty obvious that America's reputation is on the line.' 'Will we defend democratic allies against authoritarian aggressors?' McConnell asked. 'That's the international concern that I have about this, and I think a number of my fellow members share that view.'
