Mizuho shares slide 7% after denying decision on reported Rakuten Bank investment shift

TL;DR

Mizuho Financial Group’s shares declined approximately 7% after the company clarified it has not yet decided on investing in Rakuten Bank. This contradicts earlier media reports suggesting an imminent move. The situation remains uncertain as the company explores options.

Shares of Mizuho Financial Group fell as much as 7% on Monday after the company clarified that it has not yet made a decision regarding an investment in Rakuten Bank, contradicting earlier media reports suggesting an imminent move.

The decline followed reports by Yomiuri Shimbun, which claimed that Mizuho was planning to shift its stake from Rakuten Card to Rakuten Bank. Mizuho stated that it is exploring various options, including the possibility of investing in Rakuten Bank, but no decision has been finalized. The company currently holds a 14.99% stake in Rakuten Card, and the report also indicated that Mizuho Securities’ 49% stake in Rakuten Securities would remain unchanged.

Following the clarification, Mizuho’s shares traded down approximately 7.2%, while Rakuten Bank’s shares rose over 8%. Analysts are monitoring the situation for any upcoming announcements from Mizuho regarding its strategic investments in Rakuten Group, especially amid ongoing restructuring within Rakuten’s fintech segment, which aims to unify its banking, card, and securities businesses by October 2026.

Why It Matters

This development is significant because Mizuho’s potential investment in Rakuten Bank could influence the competitive landscape of Japanese financial services and fintech sectors. The stock movements reflect investor uncertainty about Mizuho’s strategic intentions, and the outcome could impact the valuation and restructuring plans of Rakuten Group’s financial units. The situation also highlights ongoing shifts within Japan’s banking and fintech industries as companies seek to optimize their portfolios amid market and regulatory changes.

Background

Earlier reports by Yomiuri Shimbun indicated that Mizuho might withdraw its stake in Rakuten Card to fund an investment in Rakuten Bank, part of a broader reorganization within Rakuten’s fintech segment. Mizuho’s recent quarterly profit surged 660% year-over-year to 228.7 billion yen, driven by fee growth and higher interest rates, which could influence its investment capacity. The report came amid ongoing industry restructuring aimed at consolidating Rakuten’s financial services by 2026.

“We are exploring various options, including the possibility of investing in Rakuten Bank, but no decision has been made at this point.”

— Mizuho Financial Group spokesperson

“The worst-case scenario for Rakuten Bank would be overpaying for its securities and card segments, but direct intervention by Mizuho could prevent that.”
