Nomura Holdings (NMR, Financial) just pulled the trigger on its biggest international deal since the Lehman era—dropping $1.8 billion in cash to acquire Macquarie Group's U.S. and European public asset management business. The move hands Nomura control of $180 billion in client assets and instantly boosts its AUM to $770 billion. More than a third of that will now be managed for clients outside Japan—a major leap for a firm long seen as too domestically anchored. CEO Kentaro Okuda framed the deal as a critical piece of Nomura's 2030 vision: a shift toward more stable, fee-based revenue and a global asset management footprint that can weather trading volatility.

Here's why it matters: about 90% of the Macquarie unit's assets are U.S.-based. And while U.S. markets have been rattled by rate shocks and trade war crossfire, Nomura is buying in at just 1% of AUM—a relative steal. The business adds $700 million in net management fees, over 700 employees, and a healthy mix of retail and insurance clients. For Macquarie, it's a clean pivot. The Australian bank is doubling down on private markets, refocusing on its core strengths while keeping its public investments in Australia. Both firms also plan to team up post-deal—Nomura gets access to Macquarie's U.S. wealth channels, while Macquarie taps Nomura's distribution muscle in Asia.

This isn't Nomura's first international play—but it might be its smartest. After past stumbles like the Lehman bet and the Archegos loss, this deal feels tighter, more calculated. Profit is already on the upswing—Nomura's earnings more than doubled to $1.9 billion in the nine months through December, with overseas units staying in the black every quarter this fiscal year. If this acquisition lands smoothly, Nomura's investment management arm could soon be pulling 60% of its revenue from outside Japan, up from just 34% last year. Investors will be watching closely as Nomura reports Q4 results this Friday.
