⚠ China's Steel Mills DecideModerate threat

Mitsui & Co. (8031) — threat to the moat

Mitsui is adding iron ore capacity for a customer whose demand it names as its main risk.

Mitsui's own description of the risk in its resources segment is short: the impact of demand for resources following a Chinese economic slowdown1. The ore from the Pilbara goes mostly to Asian steelmakers, and China is the largest of them.

Mineral & Metal Resources net profit (¥ bn, years to March)335.12024285.42025253.62026250.02027 planMitsui results, years to March 2025 and 2026
Three years of decline, and a flat plan.

The profit history shows how far this reaches. The resources segment earned ¥335.1 billion in the year to March 2024, ¥285.4 billion in 2025 and ¥253.6 billion in 202623: three years of decline without any operational problem at the main mines. The segment's plan for the current year is ¥250.0 billion4.

Mitsui's answer is volume. It expects its equity iron ore to rise from 64 million tonnes to 73 million by the year to March 2031 and 90 million by 20365, bets that assume the demand will be there. If Chinese steel output falls, more ore from everyone, including Mitsui's partners, competes for the same buyers.

The measure is segment profit against the plan. Reaching the ¥250.0 billion target on flat prices would show the mines holding their margins; missing it would show Chinese demand setting the pace.
