Asset manager institutional index net inflows measure net client subscriptions into institutional index strategies after redemptions.

BlackRock reported $41B of institutional index net outflows in the second quarter of 2026.

Negative net inflows indicate net redemptions

The company said the outflows were concentrated in low-fee index equity offerings.

That makes the metric useful for separating institutional index demand from stronger active and ETF flows.

Institutional index flows are not the same as ETF flows

Both can provide index exposure, but the client channel, vehicle, economics, and flow behavior differ.

Compare it with institutional active net inflows and ETF net inflows.
