On October 14, 2026, Federal Reserve researchers reported that U.S. semiliquid investment funds grew from $15 billion in net assets in 2018 to $388 billion in 2025. These vehicles, which include interval funds, tender offer funds, and non-traded business development companies, are expanding retail access to private markets by offering periodic, limited redemption opportunities. Growth at that pace is more than a product trend. It is a structural change in how private assets reach investors.
The shift is one of distribution. Private credit, private equity, and other illiquid assets were once reached mainly through institutional commitments and long lockups. They are now increasingly offered through structures designed for investors accustomed to more accessible products, with defined redemption windows in place of a fixed horizon.
The underlying assets, however, keep their own liquidity characteristics. Private loans and investments may have long holding periods, limited secondary markets, and valuations that are not continuously observable. A fund can offer periodic redemptions, but it cannot change what the assets are. Bridging that gap takes deliberate liquidity management, defensible valuation processes, and clear rules about when and how investors can exit.
Those requirements place greater weight on the institutional framework around the fund. Several things have to stay clearly established, even when investor liquidity differs from the liquidity of the portfolio:
- Asset ownership: what the fund holds, and on whose behalf
- Custody: where the assets sit and how they are segregated
- Valuation records: how values are set, documented, and tied to the asset record
- Redemption obligations: what the fund owes investors, and when
- Fiduciary responsibilities: who is accountable for each of the above
The investor experience can be simple while the structure underneath is not. When redemption demand and portfolio liquidity pull in different directions, the quality of the record determines how clearly a fund can show what it owns, what it owes, and what each is worth. That is hard to assemble under pressure. It has to be maintained as a matter of routine.
This is where Austin Capital Trust Company’s regulated trust infrastructure fits. Asset segregation, independent recordkeeping, and fiduciary oversight help maintain identifiable ownership as investment structures become more complex, so the framework supporting a fund stays clear even as its liquidity terms evolve.
Expanding access to private markets changes how investors participate. The underlying obligations of custody, recordkeeping, and fiduciary governance remain essential to supporting that access. As semiliquid structures keep growing, those obligations, more than the access itself, will determine how well the model holds up.
