State Street reported $59.2 trillion in assets under custody and administration as of September 30, 2026, up from $57.9 trillion at the end of June. The roughly $1.3 trillion increase, or about 2.2%, expands the base tied to the bank’s institutional servicing business.

What changed in the third quarter

State Street’s October 14 results notice lists $59.2 trillion in custody and administration assets and $6.3 trillion in assets under management. Its second-quarter disclosure listed $57.9 trillion and $6.3 trillion, respectively.

The comparison shows that the servicing base increased while the headline management total was unchanged at one decimal place. Those balances can move with market prices, client flows, new mandates and currency translation, so the quarter-end change should not be treated as a direct revenue-growth measure.

Why the custody total matters

Assets under custody and administration measure securities and other assets that State Street safeguards, records or services for clients. The figure signals scale, but fee outcomes depend on pricing, asset mix, transaction activity and the services attached to those balances.

That distinction also matters when comparing custody banks with asset managers. Fusion Market News’ look at semiliquid funds and private-credit access shows how product growth can create new servicing needs, while the BNY-Citadel tokenized repo settlement illustrates the technology investment required to support institutional markets.

What investors should watch

Investors should focus next on servicing-fee growth, net interest income, expenses, operating leverage and management’s outlook rather than extrapolating from the asset total alone. The dividend payout ratio guide offers a separate framework for assessing how earnings support shareholder distributions.

No original chart is included because the public results notice provides only quarter-end headline totals rather than a complete, consistently presented time series. The two official snapshots are stated directly here to avoid implying a broader trend than the available data supports.
