The fundamental mismatch

Direct lending assets have a weighted average life of 4–5 years and a legal final maturity of 7–10 years. Retail-facing private credit vehicles — non-traded BDCs, interval funds, and evergreen vehicles — have marketed themselves to investors with the promise of periodic liquidity, typically quarterly. The asset-liability mismatch is structural and cannot be engineered away; it can only be managed.

Every serious vehicle in this space therefore has a liquidity management architecture: some combination of a liquidity sleeve, a gating mechanism, a side-pocket provision, and a line of credit. The stress events of the past three years — particularly the Blackstone BREIT redemption surge in late 2022 and 2023, and the more contained but widely-reported pressure on a number of retail-focused credit vehicles in 2023 and 2024 — have tested these architectures in public.

How the main vehicle structures handle liquidity

The four dominant vehicle types differ in how they resolve the mismatch. None of them promises daily liquidity, and each has a legally-distinct gating mechanism.

  • Closed-end drawdown funds — no redemption rights; liquidity comes only from realisations. The cleanest structural fit for the asset.
  • Evergreen / perpetual private credit vehicles — periodic liquidity windows, typically quarterly, subject to a NAV cap (commonly 5 percent per quarter, 20 percent per year).
  • Interval funds — registered under the 1940 Act, with mandatory repurchase offers at set intervals (typically quarterly) for 5–25 percent of outstanding shares.
  • Non-traded BDCs — quarterly tender offers, also typically for around 5 percent of NAV per quarter; board discretion to suspend.

How a 5 percent quarterly gate actually works

The arithmetic is simple but sharp. A 5 percent quarterly gate means that in a stressed quarter where 10 percent of investors by NAV submit redemption requests, each redeeming investor receives approximately 50 percent of their request (pro rata), with the balance rolling into the next quarter's queue. If stress persists, the queue compounds.

The BREIT experience of late 2022 through mid-2023 is the canonical case study. Redemption requests ran materially above the monthly and quarterly limits for several consecutive periods, pro-ration was applied, and the vehicle repeatedly communicated that the gate was performing as designed. Critics argued that the episode revealed the economic cost of the mismatch even when no gate is formally breached; defenders argued that the vehicle performed exactly as disclosed. Both are true.

Lesson from BREIT
A gate is a structural feature, not a pathology. But a gate that triggers across multiple consecutive quarters creates reputational and governance costs that materially exceed the direct redemption cost — and frequently drives manager decisions on pacing of new origination, asset sales, and distribution policy.

Side pockets for distressed positions

Side pockets are the tool of last resort for positions that are genuinely illiquid or disputed — typically workout credits, litigation-bound positions, or positions whose valuation is contested. By segregating these assets, the vehicle allows new and redeeming investors to transact on the liquid portion of the portfolio without being exposed to the disputed asset's outcome.

Side pockets have a chequered reputation from their use in hedge funds during 2008–2009, where they were sometimes used as a discretionary tool to avoid realising losses. Modern usage is more disciplined: in the UK, the FCA introduced rules in PS22/8 (Protecting investors in authorised funds following the Russian invasion of Ukraine, July 2022) permitting authorised fund managers to use side pockets for assets affected by sanctions and trading restrictions arising from the invasion of Ukraine, subject to independent valuation, governance and disclosure requirements. ESMA and other European regulators have set out related conditions for use of side pockets in AIFs and UCITS. The PS22/8 regime is narrower than the broader hedge-fund side-pocket practice, but the operational principles — segregation, independent valuation, time-bound resolution — read across.

The 2023–2024 retail private credit stress episode

Beyond BREIT, a number of retail-focused private credit vehicles saw elevated redemption requests through 2023 and into 2024. The pattern was consistent: rising short rates drove competing money-market yields higher, retail investors rotated, redemption requests rose, and several vehicles had to apply pro-ration for consecutive quarters. None of the major vehicles failed, and none formally suspended redemptions — but several operated near their gate for long enough that LPs, boards and regulators took note.

The regulatory response has been measured but real. The SEC has continued its examination sweeps of private fund advisers with a particular focus on liquidity risk management and redemption disclosures. The FCA's ongoing consultation on the Illiquid Assets Sourcebook framework is likely to tighten requirements on open-ended vehicles holding private credit. ESMA's AIFMD review is heading in the same direction.

What this means for the platform

Valuation infrastructure and liquidity infrastructure are now inseparable. A vehicle that gates redemptions is, by definition, relying on its NAV mark to be defensible — because investors entering and leaving at that mark are transacting on it. The quality of the valuation framework directly determines the quality of the liquidity framework. A mark that cannot be defended in a regulator's examination or an LP's investment committee cannot support orderly redemptions at all.
