By JB Beckett (author of New Fund Order), for financial advisers, asset allocators and wealth managers.
Scale in asset management is often sold as strength. But sometimes scale is the risk.
A decade after first warning about the rise of “supertanker funds”, JB Beckett argues the private credit boom has created a new generation of vast vehicles offering liquidity while holding assets that cannot easily be sold.
Recent redemption pressures at BlackRock and Blackstone suggest the first real stress test of this model may already be under way. For advisers and allocators, the question is simple: when these new supertankers hit rougher waters, how easily can they turn? In this, his latest article for WealthDFM, JB highlights the warning signs and the critical importance of liquidity.
The metaphor of the Supertanker remains as acute today as a decade ago, just as blockages through the strait of Hormuz spike energy prices. In the early 2010s I warned about the rise of “supertanker funds” vast, lumbering investment vehicles whose scale itself becomes a source of systemic risk. The concern was simple: when a fund becomes too large, the liquidity profile of its underlying assets decays relative to the liquidity offered to investors, creating the conditions for redemption stress long before markets show it on the surface. Pimco Total Return was the totemic case study of the time, a behemoth whose size made swift manoeuvre nearly impossible when flows turned.
A decade later, that warning has sailed straight into the private‑markets boom. And in early March 2026, the inevitable happened.
The Gating Moment Arrives (Again)
On 6 March 2026, BlackRock announced it had curbed withdrawals on its $26bn HPS Corporate Lending Fund (HLEND) after receiving 9.3% redemption requests—roughly $1.2bn—yet enforcing the fund’s 5% quarterly redemption limit, paying out about $620m. Management framed the action as necessary to prevent a “structural mismatch” between investor capital and the long‑duration private credit loans the fund holds. [bloomberg.com]
This was not an isolated event. A separate BlackRock private credit vehicle also disclosed investor redemptions of 4.5%. [bloomberg.com]
Private credit, now a $1.8–2 trillion universe, has long marketed itself as a steady‑yield harbour in a choppy macro sea. But recent months have seen a surge in redemption activity, triggered in part by collapses in auto lending, subprime credit, and mid‑market mortgage finance, raising questions about portfolio durability across the space. [money.usnews.com]
Then came Blackstone.
On 2–3 March 2026, Blackstone’s flagship BCRED fund, one of the largest private credit vehicles globally at roughly $82bn in total assets allowed investors to redeem a record 7.9% of shares, equivalent to $3.8bn. The firm raised its redemption cap from 5% to 7% and, in a highly unusual step, injected over $400m of internal capital to meet the remaining requests and avoid gating the fund. [bloomberg.com]
Across the alternative‑credit landscape, Blue Owl, KKR, and others have reported heightened withdrawal pressures and loan‑quality concerns. [citywire.com]
JB Beckett’s Supertanker Thesis Resurfaces
In my earlier writings ‘Supertanker Funds: All Aboard or Time to Jump Ship?’ I described how large fund vehicles risk drifting into liquidity mismatch, with redemption rights outstripping the tradability of underlying assets. Supertankers, I argued, cannot turn on a sixpence they yaw. When markets tighten, they are forced into pro‑cyclical selling, value impairment, or redemption restrictions. [profundinvestors.org]
Those warnings have been periodically referenced in the public domain, including on Bloomberg TV commentary by analysts such as Chris White, a regular contributor on market structure who has discussed liquidity transformation and fund‑level stress dynamics in modern fixed‑income vehicles. [fixedincom…search.com]
What is different today is the composition of the “supertanker” fleet.
The early giants: PIMCO Total Return, M&G Property, multi‑asset leviathans, were invested in public‑market instruments or property with at least some ability to dispose, restructure or re‑price within observable markets. Liquidity was imperfect but visible.
The new giants: HLEND, BCRED and their private‑markets peers, hold private loans, software‑sector credit, direct‑lending packages, and structured private deals, all marked through internal models. Investors receive NAV‑based pricing and monthly/quarterly redemption windows, but the assets underneath may take months or years to realise at fair value. When redemption cycles accelerate, the mismatch becomes existential.
This is the true supertanker mismatch: semi‑liquid wrappers on illiquid cargo.
PIMCO Then vs. Private Credit Now
To appreciate the present moment, consider the comparison:
1. Transparency
- PIMCO Total Return held public bonds with transparent pricing. Redemption risk surfaced via spreads and flows.
- Private credit funds rely on internal valuation models—DCF analyses, comparable yields, spread assumptions. Investor scepticism becomes amplified in stressed conditions, as marks may not reflect true market‑clearing levels. [hedgeco.net]
2. Liquidity
- PIMCO had access to deep secondary bond markets. Liquidity could degrade but did not disappear entirely.
- Private‑market loans often cannot be sold quickly without steep discounts. Selling pressure risks value destruction, hence funds resort to gates, caps, or capital injections.
3. Redemptions vs. Supertanker Scale
- When PIMCO faced its famous outflows, the assets were at least tradeable.
- HLEND and BCRED now face outflows as large as 8–10% of NAV in a quarter, but with underlying loans that cannot be unwound at speed. Both BlackRock and Blackstone emphasised that exceeding redemption limits could endanger the structure if not capped or supplemented by internal capital. [bloomberg.com], [bloomberg.com]
4. Retail Access
- PIMCO was always widely held, but private credit funds are now aggressively marketed to wealth clients, HNWIs, and advisers, often under the promise of “democratised” access to institutional credit. As I’ve written before, this push risks confusing democratisation with liberalisation offering products whose complexity exceeds client understanding. [ifamagazine.com]
5. Macro Context
- The PIMCO episode occurred in a world of ultra‑low rates and relative geopolitical calm.
- Today’s gating events occur amid wars, supply chain realignments, AI disruption, and an emerging credit‑cycle turn, a far more hostile backdrop for illiquid assets.
Geopolitics and Liquidity: A Dangerous Intersection
The timing could not be worse. The global landscape is currently dominated by:
- US–Iran conflict and related market selloffs, which have already rattled credit markets and contributed to equity weakness in both BlackRock and Blackstone shares. [money.usnews.com]
- AI‑driven disruption, with many private credit funds heavily concentrated in software‑sector borrowers now facing repricing risk. [businessinsider.com]
- Rising corporate defaults, seen most recently in auto parts suppliers, subprime lenders and UK mortgage lenders. [money.usnews.com]
- Retail investor participation, which magnifies behavioural liquidity risk as sentiment shifts more abruptly.
Private credit has thrived on the belief that volatility is low, NAVs are stable, and loans roll forward without the mark‑to‑market drama of public markets. But this stability is now being tested.
What we are witnessing is the first full‑scale liquidity stress test of a semi‑liquid asset class that has tripled in size since 2016.
Warning Signs for Advisers and Allocators
For wealth managers, the March 2026 gating episode is not a one‑off. It is the start of a pattern. The following indicators should now be watched closely:
1. Rising Redemption Ratios
Multiple funds have faced redemption requests exceeding their quarterly limits (BlackRock at 9.3%, Blackstone at 7.9%). In semi‑liquid funds, this is a flashing red light. [bloomberg.com], [bloomberg.com]
2. Sponsor Capital Injections
When managers allocate hundreds of millions of internal capital to meet withdrawals (as Blackstone did), it signals stress; not strength, beneath the surface. [bloomberg.com]
3. Increasing Use of Redemption Caps or Gating
BlackRock explicitly invoked a 5% quarterly gate. Blue Owl and others have halted or adjusted redemption mechanisms. This reflects structural mismatch. [investmentnews.com]
4. Loan‑Quality Deterioration
Rising numbers of loans not expected to pay interest, particularly in tech‑focused portfolios, should be factored into risk assessment. [citywire.com]
5. Reliance on Internal Pricing
As volatility rises, NAVs may no longer represent true exit values. Watch for discrepancies between fund marks and secondary‑market transaction levels. [hedgeco.net]
6. Concentration in Disrupted Sectors
Software and AI‑sensitive industries remain the largest exposures for many private credit funds. This is a thematic risk, not an idiosyncratic one. [cnbc.com]
A Supertanker‑Era Checklist for Today’s Private Markets
To support advisers and allocators, here is a succinct, Beckett‑style due‑diligence checklist:
✓ Liquidity Match
- Does the liquidity offered (monthly/quarterly) align with the liquidity of underlying loans?
- What is the policy for gating, and has it been used before?
✓ Redemption Behaviour
- What were redemption levels in the last four quarters?
- How close has the fund come to breaching its redemption cap?
✓ Transparency of Valuation
- How are marks generated?
- Has the fund conducted independent third‑party pricing checks?
✓ Sector Concentration
- Are exposures skewed toward software, tech lending or single‑theme corporate credit?
- What would a sector‑wide repricing do to NAV?
✓ Sponsor Alignment
- Has the manager used internal capital or altered redemption rules recently?
- Does this indicate strength, or concealed liquidity pressure?
✓ Contagion Sensitivity
- What would happen in a correlated geopolitical or economic shock?
- Are liquidity buffers sufficient?
✓ Communication Discipline
- Have investors been informed clearly and promptly (a known challenge in semi‑liquid funds)?
Conclusion: The Return of the Supertanker Problem
A decade ago, the industry’s supertankers were public‑market behemoths. Today, they are private‑market leviathans, more opaque, less liquid, more vulnerable to redemption shocks, and distributed across the wealth channel at unprecedented scale.
The events at BlackRock and Blackstone are not anomalies. They are the natural outcome of offering liquidity on assets that cannot provide it.
For advisers, allocators, and wealth managers, this is a moment to revisit the core tenet of the New Fund Order:
Liquidity is not a feature. It is a liability, one that must be underwritten with discipline, scepticism, and structural understanding.
The supertanker era never ended. It simply drafts in new waters.
