Monex Group announced a capital and business alliance with IRBANK Inc. on 9 November 2026, alongside a signed share subscription agreement. It will subscribe for newly issued shares through a third-party allotment. IRBANK is due to become an equity-method affiliate after completion. Monex expects the transaction to have little effect on consolidated results.
IRBANK has provided Japanese company results, prices, turnover and margin balances since 2013. Monex cites about one million monthly active users, measured by browser in Google Analytics 4. The IRBANK service released an API and MCP server in July. Monex Securities followed in August with an MCP service for account information. The IRBANK corporate entity was formed in April 2025 and had ¥31 million of capital at the end of April 2026.
The official notice says viewing Monex Securities balances in IRBANK became available on 9 November. Placing orders through IRBANK remains a future project. The partners also plan to explore AI-assisted research and execution for Japanese and US stocks and crypto, and to expand their reach through financial instruments intermediation.
