Markets lie, but liquidity tells the truth. This week's quiet filing from Moody's—urging the National Association of Insurance Commissioners to tighten oversight of private credit ratings—is not a compliance memo. It is a confession of competitive weakness masquerading as systemic risk alarm.
Insurance companies have been quietly rotating capital into private credit for years. The yield premium is real, the volatility is deferred, and the ratings are... negotiated. Moody's, the incumbent gatekeeper, watches this flow and sees its own archaic models bypassed. So it fires the only weapon left: regulatory friction. The aim is to raise the cost of entry for nimble competitors that deploy AI-driven analytics and alternative data.
This is not about protecting policyholders. It is about protecting a business model.
Context: The Private Credit Expansion
The insurance industry manages over $7 trillion in general account assets in the US alone. A significant slice now sits in private credit—direct lending, asset-backed securities, real estate debt. These instruments are illiquid, marked-to-model, and often rated by private agencies that occupy a regulatory gray zone.
Unlike Moody's, S&P, and Fitch—federally recognized as NRSROs—private rating shops, efficient or not, have become the go-to for insurers chasing yield. Their models are faster, cheaper, and often more bespoke. They can ramp up on new asset classes without the inertia of legacy infrastructure. For a CEO under pressure to meet reserve yields, that is attractive.
For Moody's, that is existential.
The NAIC is now the battleground. If it adopts Moody's recommendations, the compliance burden on private ratters will spike. Novel models must be explained, audited, back-tested, and documented according to standards set by the very incumbents they bypass. That is not regulation. That is rent extraction.
Core: The Real Risk is Concentration, Not Opacity
During my 2021 audit of 15 major DeFi protocols, we identified that 70% of early NFT volume was wash trading driven by manipulated liquidity pools. The lesson was simple: when assets are opaque and flows are murky, bad actors signal through volume. The same dynamic applies here.
The concentrated risk is not that private rating firms are too loose. It is that systemic chokepoints already exist. Insurers rely on a handful of gatekeepers to validate every liquid, transparent asset they hold. Adding more layers of compliance to private market participants only consolidates power in the hands of the three giants.
Let me be explicit about the mechanics. Credit rating practice rests on two pillars: default probability estimation and loss severity modeling. Public markets have decades of granular default data. Private credit has almost none. Every model in this space IS calibrated on limited, sometimes cherry-picked, evidence.
The only way to evaluate a private rating firm is through feature-level analysis. We need to see the variables baked into the models—cash flow coverage ratios, loan-to-value, sponsor quality, sector concentration. And published model validation results that reveal how the model behaves under extreme stress—2008-style, COVID-style, '22 style.
Here is the hidden variable: correlation. Private credit is correlated with public credit at the asset level, but it is far more correlated at the systemic level. Insurers loaded up on private debt during the low-rate era. Their portfolios are structurally exposed to a repricing event. When default waves hit, the private portfolios will fall faster—not because the ratings are bad, but because the underlying assets are locked. There is no bid. There is no exit.
That is the true systemic fragility. And calling for stricter supervision of the rating agencies misses it entirely.
Regulatory lobbying, at its purest, is the practice of manufacturing asymmetry: making your own business durable by making the environment more difficult for your replacements.
Contrarian: The Decoupling Thesis
The dominant narrative frames this as 'incumbent experts sound the warning on reckless challengers.' The contrarian read is that Moody's is the systemic risk, not the solution.
This is regulatory capture dressed in prudence. Every proposed rule will layer onto an already convoluted insurance governance framework. The unintended consequence will be a reduction in market participation and another step toward oligopoly. If NAIC ratifies this, private credit investors will effectively outsource legal liability to Moody's models. We saw this movie before: 2008 was not a failure of private markets. It was a failure of centralized rating models on toxic public assets.
The decoupling thesis goes further: private credit is the only place where alpha remains uncorrelated to public market signals. As algorithmic public trading compresses margins, the real returns are in bespoke, negotiated assets—private debt, infrastructure, specialty finance. These are precisely the instruments private ratters serve best. Their responsiveness to new asset classes is not sloppiness. It is agility.
Yet there is a deeper structural concern the call itself reveals. The rise of private rating agencies signals a fragmentation of information authority. That fragmentation is a positive for efficient pricing, but dangerous for governance. Markets hate ambiguity. Insurance operations demand clear signals of creditworthiness. The tension between speed and authority will not be resolved by regulation—it will be resolved by whatever disintermediation tech builds next.
This is where my 2024 work on Bitcoin ETF regulatory arbitrage comes in. I identified a 12% cross-border alpha opportunity across Nordic jurisdictions because the ETF wrapper created an information delay between US and EU price discovery. The same principle applies here: everyone sees the same rating letter, but only a few understand what actually underwrites it. The real alpha is not in the rating—it is in the model margins.
Takeaway: We Do Not Predict; We Position
The NAIC's decision, whatever it is, defines the shape of the next credit cycle. If they cave to Moody's, blue-chip assets keep their premium and private credit becomes a boutique allocation for a few nimble insurers. If they resist, the market enters a chaotic but honest phase of innovation, mimicking the post-Mt. Gox exchanges that learned to survive by building stronger risk rails.
Survival is the first metric of success. Structure emerges from the chaos of contraction. The incumbents will lobby, the challengers will pitch, and the politicians will posture. But the only hard signal that matters is the one that cannot be faked: real, measurable flow.
Watch where the capital moves. Watch which rating agencies insurance treasurers actually pay for with finality. Not with votes in a committee—with dollars in a settlement.
Alpha is found where others see only noise. And this noise has a signal. The final metrics are currency in motion. Every other measure is a traded variable, ceding the true edge to those who read the ledger, not the rhetoric.
