The rise of non-bank financial intermediaries, opaque valuations, and direct ties to the bank system, explain how risks in credit have shifted into the shadows.

The structure of the global credit creation system has undergone a paradigm shift over the last 15 years. Post-2008, international regulators imposed stringent capital adequacy, liquidity coverage, and stress-test requirements on global banks – particularly codified in Basel III – thus raising the cost of capital for mid-market corporate lending and structured financing.

A significant portion of this bank capital has been funneled into the non-bank financial intermediation (NBFI) sector – alternatively dubbed the “shadow banking” complex – which has since grown to manage over 50% of the world’s financial assets. As of 2026, this shadow system consists of a sprawling network of private credit funds, private equity managers, hedge funds, money market funds and specialized finance companies who control over $220 trillion. Within this broader ecosystem, private credit has experienced the most aggressive expansion, surging from a $300 billion unique asset classes post-2008 into a $1.8 trillion global debt powerhouse. The shift of credit risk off of the balance sheets of regulated commercial banks and into the NBFI system was initially viewed as a positive, dispersion mechanism for systemic risk, but as rates rise and the ability of corporations to service debt declines, the hidden risks and interconnectivity of this system pose a threat to financial stability.

The Anatomy of the Private Credit Supercycle

Private credit funds operate as direct lenders to middle-market and large-cap corporates – with non-bank fund managers structuring and retaining direct loans to borrowers in private placements. This system differs from the public high-yield and syndicated loan markets in that these loans are not bank-syndicated or rated by third-party rating agencies.

Borrowers are willing to accept higher interest rates for the speed, flexibility, and secrecy of a private placement, plus the certainty of funding during periods of public market volatility. On the demand side, pension funds, university endowments, sovereign wealth funds, and high-net-worth insurance companies – all seeking yield during the zero-rate environment – were able to access an asset class offering greater flexibility in the form of floating rate loans, while protecting capital during the tightening cycle.

But the rush into private credit has led to deterioration in underwriting standards and transparency:

  • Opaque Valuation Methodologies: The private loans are not marked-to-market on a public exchange, making it difficult to value assets and assess the true level of risk. While some funds may use a third-party evaluation, most utilize an internal “mark-to-model”, allowing fund managers to hide volatility and downside risk during periods of economic stress.
  • “Extend and Pretend” Restructurings: When companies face debt-service challenges during a higher-rate environment, private credit managers are likely to allow PIK (payment-in-kind) and coupon deferrals to keep the loan on the books and avoid default.
  • Layered Fund-Level Leverage: In addition to the leverage on company assets, private credit funds are also beginning to use fund-level leverage to boost net IRRs. Subscription lines, NAV loans and asset backed leverage facilities add additional debt on top of the loan to the underlying company.

The Web of Bank-NBFI Interconnectedness

One of the key myths about shadow banking is that the risks have been entirely moved out of the traditional banking system. The truth is that commercial banks and non-bank financial intermediaries are more interconnected than ever before.

Banks provide the liquidity underpinning private market funds and, if there is a wave of defaults in the corporate credit markets, the losses will be transferred back to the banking sector. For example, if the value of private credit assets were to be sharply discounted due to a wave of corporate defaults, the losses would be passed on to the special financing lines at the banks that have been used to fund these private credit funds.

"The exposure of banks to non-banking financial institutions (NBFIs) is much higher than previously thought, according to the latest data. In the past 5 years, the direct exposure of banks to NBFIs has skyrocketed, which means a credit shock in the unregulated private markets would have a fast and severe second-order impact on the core banking system through liquidity squeezes, margin calls and downgrades of wholesale credit exposures," writes the Financial Stability Board (FSB) and the European Central Bank (ECB) in their latest joint report.

Liquidity Mismatches and the Democratization of Private Markets

The systemic risk embedded in private credit is exacerbated by the fact that the asset class is undergoing a rapid process of "democratization". Historically, private credit was mostly bought and sold by institutional investors who had a multi-year investment horizon. However, private credit products today are being distributed to more liquid evergreen vehicles and interval funds as well as in the form of non-traded business development companies (BDCs).

Fund structures that allow monthly or quarterly redemptions by retail investors have a fundamental mismatch of liquidity profiles with the underlying illiquid 5-7 year corporate loans. In a situation of severe macroeconomic deterioration or a sudden loss of confidence in the asset class, redemptions from private credit funds could easily overwhelm available liquidity (typically in the form of cash and public securities) and force liquidations of private loans at steep discounts to face value. If managers of interval funds or evergreen private credit vehicles are unable to gate redemptions or sell illiquid private assets at significant discounts to satisfy retail investors, it could lead to "bank run" dynamics similar to what is seen in the traditional banking system, but with less protection from deposit insurance and the lender-of-last resort function of central banks.

Macroprudential Toolkits Get Updated as Regulators Anticipate Systemic

Risk

With the recognition that light-touch regulation of the shadow-banking system could pose a risk to the stability of the entire financial system, international regulators in 2026 are beginning to take the first steps in beefing up macroprudential tools:

In the U.S., the Financial Stability Oversight Council (FSOC) has adopted new

framework guidelines in order to streamline the designation process for systemically important financial institutions (SIFIs). A private asset manager designated as a non-bank SIFI would be subject to enhanced prudential oversight by the Federal Reserve, including higher capital requirements, consolidated leverage limits as well as regular liquidity stress tests.

Meanwhile, the ECB and the Bank of England have begun a system-wide stress-testing exercise (unlike traditional bank stress tests, this one involves simultaneous liquidity shocks to banks, private credit managers, hedge funds and insurance companies) in order to understand the complex interconnectedness and counterparty risk between different segments of the financial system.

Outlook

The migration of credit creation from the regulated banking sector to the shadow banking and private credit markets has resulted in a bifurcated financial system which consists of a heavily regulated core (commercial banks) and an opaque, leveraged and fast-growing periphery (NBFIs). As the private credit market navigates its first major prolonged period of higher-for-longer interest rates, the lack of standardised price discovery and deep interconnection with the traditional banking system poses a serious risk to global financial stability. Policymakers around the world will have to look behind the curtain of private market opacity and enforce systematic leverage tracking and transparency across different financial sectors in order to avert potential hidden credit shocks to the real economy.
