A follow-up to “The Structural Limits of Tokenized Private Credit as Collateral”

When we first published our thesis, we identified four structural issues with using private credit as DeFi collateral based on first principles. We analyzed how this asset class would perform under stress by examining NAV accounting, redemption gates, and liquidation mechanics. At the time, these conclusions were theoretical. 

Now, recent data confirms that every mechanism we flagged has appeared in practice. The thesis held up, and the exact failure modes we warned about have unfolded one by one.

Problem One, Revisited: The Stale Mark Has a Number Now

We laid out how stale NAV is an adverse selection engine: a window where the best-informed actors can max out liquidity against an asset the protocol still thinks is solid. 

Fast-forward to May 2026. The Federal Reserve has now identified a specific cause for that window: payment-in-kind (PIK) provisions. When borrowers cannot make cash interest payments, they simply add the shortfall to the loan principal. But this doesn’t solve anything. If anything, it formalizes the underlying problem. 

For a lender, a loan on PIK is deteriorating in every meaningful way, yet on paper it appears healthy and continues to accrue interest. NAV administrators have no natural trigger in their workflow to detect this issue in real time, so the degradation remains hidden until the borrower's cash shortages become undeniable. This is precisely the issue we highlighted previously, which has now transitioned from theoretical risk to standard accounting practice.

Recent default rates illustrate the real-world scale of this issue. Depending on the reporting methodology, U.S. private credit default rates range from 2.51% for senior secured loans according to Proskauer, to a projected 2.0% from KBRA, or a record 6.0% under Fitch’s broader calculation. Narrower indices only track explicit payment failures, whereas Fitch includes distressed restructurings and selective defaults, which Moody’s estimates account for approximately 65% of all private credit defaults. 

Consequently, protocols that establish loan-to-value ratios based solely on smooth net asset value curves risk underestimating portfolio distress by focusing on the lower default figures rather than the broader market reality.

Problem Two, Revisited: Apollo Showed What Liquidation Through Issuer Machinery Looks Like at Scale

We pointed out that, without a true secondary market, liquidation happens through the issuer’s own redemption machinery: instant sleeves, credit lines, periodic NAV redemptions. 

This setup works fine when redemptions are isolated. But when everyone heads for the exit at once, those layers get stress-tested. And they fail, because they were never built for mass redemption.

For example, in March 2026, Apollo’s $15 billion flagship private credit fund fulfilled only 45% of redemption requests. This triggered gates that allocators previously viewed as simple legal boilerplate.

Let that sink in: Apollo, one of the largest and most sophisticated players, had to limit withdrawals by half. Meanwhile, Blackstone’s BCRED lifted redemption caps and covered the shortfall using executive capital during a $3.7 billion redemption wave. Major firms including Blackstone, BlackRock, and Morgan Stanley faced over $10 billion in redemption requests in Q1 2026 alone, demonstrating that this issue affects the core of the market.

We are not talking about shaky, marginal funds here. These were the ones with the best liquidity engineering in the industry, the “better issuers” we credited up front. The lesson is that instant sleeves, credit lines, and NAV redemptions act as temporary bridges, not guaranteed buyers, and every bridge has a limit. When you tokenize a fund and connect it to a DeFi lending protocol, you inherit those exact limits without the firm's balance sheet or reputation to absorb the shock. As a result, the risk moves much faster while the liquidity constraints remain unchanged.

Problem Three, Revisited: The Correlation Showed Up on Schedule

We originally noted that private credit values would plummet precisely when liquidators need liquidity most, showing that credit quality is procyclical rather than a hedge against DeFi market stress. 

Recent data confirms this structural vulnerability. The same interest rate hikes squeezing borrower cash flow and raising Fitch’s default rate are also suppressing risk appetite across leveraged on-chain positions. Additionally, major financial institutions are feeling the impact: JPMorgan is discounting its private credit exposure and restricting new loans, while Deutsche Bank (with $30 billion at risk) issued warnings about interconnected portfolios that negatively impacted its stock price. 

As major banks face direct losses, private credit can no longer be credibly viewed as a low-correlation collateral asset.

Problem Four, Revisited: The 2022 to 2023 Precedent, Updated with a 2026 Postscript

We gave credit where it was due: bankruptcy-remote vehicles, independent admins, permissioned venues. These were real improvements since the early days. But those upgrades only shift who holds the bag, not how quickly you can turn illiquid assets into cash. 

The latest round of redemption-gate data makes that clear. None of these fixes stopped Apollo’s gate, BCRED’s cap-lift, or the wave of capped withdrawals across big non-traded BDCs and interval funds in late 2025 and early 2026. 

The wrappers are more institutional, but the speed limit hasn’t budged.

The One Place the Industry Has (Quietly) Agreed with Us

Recent data highlights a telling trend: only roughly 10% of total tokenized real-world asset (RWA) value functions as active on-chain lending collateral, representing $3 billion out of an $18 billion market. 

Furthermore, emerging frameworks like Centrifuge’s ERC-7540 standard explicitly accommodate redemption windows rather than promising instant liquidity. This shift reflects a clear, pragmatic realization from leading protocols that offering immediate liquidity on illiquid credit assets presents inherent structural risks.

Taken together, these two facts show that the experiment has already run its course. Sophisticated allocators are tokenizing private credit at scale for access and distribution (the key advantages we highlighted), yet they avoid using it as DeFi collateral. The 90% of RWA value not integrated into lending protocols is the logical outcome reached by those who closely analyze the underlying terms.

What Hasn’t Changed

The conclusion of the original piece requires no revision, only reinforcement. 

While conservative settings, such as lower LTVs, supply caps, and isolation modes, reduce this gap, they cannot fully eliminate it because the mismatch is categorical. Protocols that list a private credit token as collateral today are underwriting the same four problems described six months ago, except three of them now come with a named 2026 case study attached. 

The fourth issue (correlation with stress that triggers liquidations) cannot be solved by better engineering. That vulnerability is an inherent feature of the asset class itself.

Some assets should be owned, not leveraged. The data since publication hasn’t complicated that sentence. It’s just given it footnotes.
