China's municipal bond issuance for infrastructure investment surged in Q2 2026, with a record volume of special-purpose bonds directed toward power grid expansion and construction projects. These are among the most copper-intensive infrastructure categories, with grid infrastructure consuming approximately 30 kg of copper per $1,000 of investment.
The bond-driven spending is part of Beijing's strategy to offset slowing real estate investment. Grid investment alone is projected to rise 18% year-on-year in 2026, supporting construction of ultra-high-voltage transmission lines and distribution network upgrades. China's State Grid Corporation has accelerated its 2026 capex plan to a record level, focusing on renewable energy integration and inter-provincial transmission capacity.
CRU Group estimates that China's refined copper demand will grow 3.2% in 2026, with grid and renewable energy accounting for the majority of the increase. While the real estate sector remains weak - roughly 25% of Chinese copper demand - infrastructure spending is filling the gap. The import arbitrage between SHFE and LME remains open, with SHFE prices at a narrow discount that still supports import economics.
