When Illiquid Assets Trade
Business development companies, closed end funds, mortgage real estate investment trusts, and a dozen other publicly traded vehicles turn illiquid strategies into tradeable securities. They hold the same loans, the same mortgages, the same private credit that tokenized real world assets hold. The difference: they trade on exchanges, every day, with real volume. This report explores how they work, how they break, and what makes them liquid.
1. The Pattern
There is a class of publicly traded vehicle that wraps illiquid strategies (private loans, mortgage pools, CLO (collateralized loan obligation) tranches, litigation claims, music royalties, aircraft leases) in a structure that trades on an exchange. The underlying assets cannot be sold in a day. Yet the wrappers trade every day, with real bids, real volume, and real price discovery.
This is not a niche corner of finance. Business development companies (BDCs) alone manage over $200B in assets. Mortgage real estate investment trusts (mREITs) run portfolios exceeding $100B each. Closed end funds (CEFs) collectively hold $258B in net assets across 433 vehicles.
Master limited partnerships (MLPs), aircraft lessors, timber REITs, shipping companies, drug royalties, precious metals streamers, listed private equity trusts. Add it all up and you are looking at over $500B in publicly traded securities backed by assets that would take weeks or months to liquidate.
The pattern: a manager assembles illiquid assets, wraps them in a structure with leverage limits and distribution requirements, lists on an exchange, and a market maker posts two sided quotes. The price is almost never equal to the reported net asset value (NAV). That gap is the market's real time opinion on risk, liquidity, and trust.
