Marubeni-Itochu SteelNarrow moat

ITOCHU (8001) — moat facet

ITOCHU shares a steel trading business with the rival that shares its founder.

Marubeni-Itochu Steel was established in 20011 as a joint venture between two trading houses that trace their founding to the same man, Chubei Itoh23. ITOCHU owns 50% and the venture contributed ¥20.2 billion in the year to March 20264.

A joint venture between two companies with the same founder.

The venture trades steel products between mills and users, and it gives both houses a presence in steel without a direct rivalry.

It sits in the Metals & Minerals division, beside IMEA's iron ore, which means ITOCHU is present at both ends of the steel chain: supplying the ore and distributing the product.

The joint venture's parents are now of very different sizes: ITOCHU earned ¥900.3 billion in the latest year5 and Marubeni ¥543.9 billion6.

The measure is its contribution through the steel cycle. At ¥20.2 billion it is steady; a fall would reflect weaker steel demand in Japan and Asia.
