China’s Mega-Dam Project Boosts Metal Markets, but Impact Likely to Be Gradual
China’s launch of a massive 1.2 trillion yuan (S$218.5 billion) hydropower project in Tibet has sparked optimism in metals markets, though analysts caution that its long development timeline and ongoing construction sector weakness could limit near-term demand.
Markets reacted swiftly after the groundbreaking ceremony on July 19, attended by Premier Li Qiang. Iron ore futures on the Singapore Exchange for October delivery surged as much as 4.9% this week, while Shanghai steel futures climbed nearly 4% on Thursday from pre-announcement levels.
Set to be the world’s largest and most expensive hydroelectric facility, the Yarlung Tsangpo River dam is expected to generate 300 trillion watt-hours of electricity annually—tripling the output of the Three Gorges Dam. This output would be over five times Singapore’s total electricity consumption in 2024.
Estimates from LGMI Steel suggest the project could drive demand for up to six million tonnes of steel, vastly exceeding the 70,000 tonnes used in the Three Gorges Dam. The rugged terrain and extreme climate of the Tibetan Plateau will require higher steel intensity.
Macquarie’s commodities strategist Florence Sun projected steel consumption of three to five million tonnes, composed of rebar and specialized steels, due to the unique geographic challenges. She noted that the dam’s cost is 4.5 times higher than its Three Gorges predecessor.
However, the full impact on ferrous metals will unfold gradually over the five-to-seven-year construction timeline, as procurement is expected to be staggered. Edward Meir, senior metals analyst at Marex, noted that steel and cement will see the most significant demand bump, with a modest boost for copper tied to power transmission needs.
Still, a sluggish construction sector remains a drag on metals consumption. Sabrin Chowdhury, head of commodities at BMI, said that one project alone won’t be enough to sustain a broader demand recovery: “More initiatives will be needed to lift metals markets meaningfully.”
Citi Research echoed this in a recent report, pointing to limited front-loaded demand and a slow rollout of metal use. Nonetheless, the dam signals China’s commitment to long-term investment in nationwide power grid infrastructure. While specific copper and aluminium usage data is unavailable, ultra-high voltage transmission lines—especially aluminium-intensive—will be essential to deliver electricity to eastern and southern China.
Policy Momentum: Anti-Involution and Supply Reform
Beyond the dam, the recent rally in China’s ferrous markets has also been driven by political rhetoric targeting industrial overcapacity. Iron ore, coking coal, and coke have posted gains amid expectations of supply-side reforms under China’s “anti-involution” (fan nei juan) policy.
According to a July 15 Citi Research note, the campaign seeks to halt destructive price competition and chronic overproduction that have eroded industry margins. The policy echoes the 2016–2017 reforms that sparked a historic iron ore rally, though analysts caution against expecting a repeat performance.
Despite the price uptick, China’s metals industry continues to face imbalances. Weak demand from the real estate sector collides with rising production, keeping supply above sustainable levels. Traders are betting on government-led capacity reductions to rebalance the market.
However, Citi analysts warn the rally may be short-lived, citing fundamental differences from the last reform wave. Urban renewal and infrastructure plans now emphasize measured upgrades rather than demolition-heavy redevelopment, suggesting lower steel intensity going forward.
The anti-involution message has gained traction at the highest levels. At a meeting led by President Xi Jinping on July 1, the Central Finance and Economic Affairs Commission called for enhanced product quality and a structured phase-out of outdated industrial capacity—part of a broader push to break free from deflationary pressures.
