Morgan Stanley (MS) Q3 2026: Record Net New Assets of $232 Billion

Morgan Stanley (MS) third-quarter 2026 results, released on October 14, 2026 in its 8-K earnings release, financial supplement and earnings call, showed record wealth management net new assets and net revenues of $20.338 billion, up 12% year over year [1][2][3]. Revenue growth strengthened, but profit conversion did not improve at the same pace. Four questions had framed the company before this report: whether wealth management asset inflows could last, whether the wealth management pre-tax margin could keep rising, whether Institutional Securities could sustain its high second-quarter revenue, and how excess capital would be used. In the quarter ended September 30, net new assets set a record, and Institutional Securities fell from its peak but held at a high level; the wealth management margin stayed at 30.4%, and the capital buffer and pace of buybacks were unchanged [1][3]. Overall, the revenue base is moving higher, but more than half of the new assets came from IPO-related money, and whether those assets stay and convert into fee-based assets remains unproven.

Morgan Stanley is a New York-based financial holding company with three reporting segments: Institutional Securities, Wealth Management and Investment Management [4]. Institutional Securities provides underwriting, M&A advice, trading and financing to companies and institutions. Wealth Management serves individuals and workplace clients with advice, brokerage and banking services, earning mainly fees charged on client assets and the spread between deposits and loans. In 2025 these two segments together made up about 90% of net revenues [4].

Record net new assets lean on IPO flows and one large mandate

Wealth Management net new assets reached a record $232.4 billion in the third quarter. That was 57% more than the $148.1 billion in the second quarter and nearly three times the $81.0 billion a year earlier; fee-based asset flows were $80.5 billion, up 92% year over year [2]. Net new assets for the first nine months totaled roughly $500 billion, well above the $356 billion for all of 2025 [3][4].

The composition of these inflows matters. The company said just over half were associated with IPO-related flows, which come from employees, early investors and fund distributions of stock [1][3]. The chief financial officer said nearly half of the fee-based flows came from a single new corporate retirement mandate [3]. A rough calculation from these approximate shares leaves about $70 billion to $80 billion of other inflows, close to the total a year earlier, so it is not yet possible to say whether inflows outside IPOs have risen.

The new assets are already showing up in revenue. Wealth Management net revenues were $9.065 billion, up 10% year over year, and asset management revenues were $5.544 billion, up 16%, as fee-based client assets grew to $3.155 trillion [2]. Management said retention rates are steady but did not disclose a figure [3].

Net interest income moved the other way. In the second quarter, management expected a modest sequential increase in third-quarter net interest income [5]; it came in at $2.228 billion, down about 1% from the prior quarter [2]. The decline reflects a deliberate intake of nearly $30 billion of higher-cost deposits, which lifted the period-average cost of deposits from 2.54% to 2.72% [2][3]. Management expects a modest increase in the fourth quarter and expansion in 2027 on loan growth, and said the funding benefit from the deposits will come through gradually over next year [3].

Institutional Securities fell from its peak but held a high level

Institutional Securities net revenues were $10.029 billion in the third quarter, down 9% from $11.040 billion in the second quarter and up 18% year over year [2]. Both main businesses held at high levels. Investment banking revenues stayed above $2 billion for a second straight quarter ($2.437 billion in the second quarter and $2.159 billion in the third), and equity revenues stayed above $5.5 billion ($6.3 billion and $5.799 billion) [2].

Client financing demand supported the equity business. Equity revenues rose 41% year over year, and the chief financial officer said prime brokerage financing revenues grew on higher average client balances [2][3]. Momentum from the second quarter carried into July before client activity moderated through September, and equity revenues still held at a high level [3].

Not every business line strengthened. Advisory revenues rose 30% year over year, equity underwriting fell 19% on lower IPOs and blocks, and fixed income fell 7% [1][2]. Segment pre-tax income rose only 9% year over year, and the pre-tax margin fell from 37% to 35% because execution-related expenses and technology spending lifted non-compensation expenses by 30% [1][2].

Conclusion

The quarter strengthened the view of Morgan Stanley's growth engine, while the view of profit conversion and capital use is largely unchanged. Under an asset-based fee model, growth in fee-based assets turns into management fees over the following quarters, but profit conversion has not kept pace: firm pre-tax income rose 7% year over year, slower than the 12% rise in revenue, and the wealth management pre-tax margin has held at 30.4% to 30.5% for three straight quarters [2]. On capital, the standardized Common Equity Tier 1 ratio was 14.9%, management cited 300 basis points of excess CET1, and the firm repurchased $1.54 billion of stock in the quarter while keeping its $1.15 quarterly dividend per share [1][3].

These conclusions have limits. The retirement mandate is a one-time inflow, IPO-related money moves with lockup expirations and market windows, and Institutional Securities activity had already slowed in September. The next tests are whether total inflows hold as the IPO share falls, whether net interest income rises in the fourth quarter, and whether Institutional Securities can sustain its current revenue in the fourth quarter.
