The LMEX index continues to experience downward pressure even as China's manufacturing PMI rose above the 50 mark, indicating expansion. This improvement in China's manufacturing sector is seen as a supportive factor for copper, driven by increased AI-related exports, according to FX Street.

Despite the positive signals from China's PMI, the broader LMEX index has not reflected this optimism, suggesting other market forces are weighing on the index. Copper remains a key beneficiary of AI-driven export growth, highlighting its strategic importance in emerging technologies.

For Japanese investors, this dynamic underscores the importance of closely monitoring global manufacturing trends and their impact on metal indices like LMEX, as these factors can influence commodity-linked equities and FX markets in Japan.
