Q3 2026 results and fall business update: margin, new assets, client cash
Test: Net interest margin at or above the Q2 level of 3.00% and more core net new assets than a year earlier pass; a lower margin or client cash leaving sweep accounts fails.
Outcome: Net interest margin rose to 3.04%, core net new assets rose 38% to a record $190.4 billion, and total sweep cash grew $7.1 billion, although only because of cash tied to client long/short strategies.
