SEI to launch two LTAFs in private markets 'expansion'

SEI has secured regulatory clearance to establish two long-term asset funds as part of a broader expansion strategy in private markets, according to an announcement on July 2, 2026. The regulatory approval enables the firm to operationalize LTAFs—a fund structure specifically designed to accommodate longer investment timelines and reduced liquidity constraints compared to traditional open-ended vehicles.

The initiative directly supports the UK's "Mansion House ambition," a regulatory agenda aimed at facilitating institutional capital deployment into private markets by creating supportive fund structures and reducing unnecessary restrictions on long-term commitments. By launching two dedicated LTAFs, SEI positions itself to capture demand from institutional investors, family offices, and pension funds seeking exposure to private markets without the redemption pressures inherent in shorter-dated fund vehicles.

The timing reflects broader industry trends toward private market expansion, as institutional allocators increase target allocations to illiquid alternatives. SEI's dual-fund approach suggests differentiation across investor segments or strategy types, though specific fund mandates and target asset sizes were not detailed in the announcement. This regulatory milestone underscores SEI's commitment to institutional-grade alternatives distribution and custodial capabilities in an increasingly competitive private markets environment.
