Rakuten Bank stock slid 4.2% to trade at ¥6,480 during the session, reversing a large portion of the prior day’s rebound after the investment narrative that had propelled shares higher was effectively scaled back in official statements. The stock had rallied on reports that Mizuho Financial Group was considering an investment in the bank as part of Rakuten Group’s planned reorganization of its financial businesses.
Market momentum shifted when Mizuho’s shares dropped sharply following a clarification from the Japanese lender that it had not yet decided on investing in Rakuten Bank. That clarification followed reporting that suggested Mizuho intended to make additional investments in the online bank.
Analysts say the reversal is being exacerbated by persistent structural uncertainty around the larger reorganization effort. Jefferies analysts highlighted that Rakuten Group’s FinTech segment is undergoing a reorganization expected to conclude in October 2026. Under the plan, the bank, card, and securities operations would be reorganized under a single group.
Jefferies flagged a potential downside scenario in which Rakuten Bank might overpay to acquire the securities and card businesses. The analysts noted, however, that direct intervention from Mizuho could mitigate that risk.
In a financial outline provided by Jefferies for Rakuten Bank (5838), the firm suggested the restructuring could create a platform capable of producing ¥200 billion in operating profit. At a 15x earnings multiple, that level of operating profit could be consistent with a ¥3 trillion market capitalization. The proposed reorganization would also materially dilute ordinary shareholders, reducing their stake from 51% to 21.8% - a development Jefferies warned could prompt concerns about pressure on those shareholders.
Rakuten has stated that combining the entities would generate ¥53 billion in cost synergies and ¥32 billion in revenue synergies, driven in part by cross-selling opportunities. A third committee has approved the scheme.
Investors are weighing a combination of a diminished deal catalyst, unresolved restructuring risk, and a challenging macroeconomic environment for rate-sensitive financial companies. Those factors pushed Rakuten Bank shares toward the bottom of today’s intraday range of ¥6,463 to ¥6,896.
The average 12-month analyst price target for the stock is ¥7,948.75. Analyst coverage shows four buy recommendations and one sell recommendation, a mix that market participants interpret as evidence the pullback is driven more by sentiment than by immediate fundamental deterioration. Nevertheless, analysts caution that heightened volatility is likely to continue until the FinTech reorganization is formally finalized.
