Nonbank Financial Institutions (NBFIs): The New Face of Shadow Banking

Nonbank Financial Institutions (NBFIs), often associated with shadow banking, refer to the network of financial companies and activities that perform bank-like functions outside the traditional banking system. These entities engage in credit intermediation, liquidity transformation, and maturity transformation, but unlike banks, they generally lack direct access to central bank liquidity facilities and deposit insurance.

What Are NBFIs?

NBFIs are financial institutions that channel funds between investors and borrowers outside the regulated banking sector. According to the Financial Stability Board (FSB), the U.S. NBFI sector accounts for more than half of global nonbank financial assets, underscoring its global importance and systemic scale.

Key participants include:

  • Money Market Funds (MMFs) such as Vanguard, Fidelity, and BlackRock
  • Asset Managers and Investment Funds such as BlackRock, PIMCO, State Street, Blackstone, and Apollo
  • Securitization and Structured Finance Vehicles such as Fannie Mae, Freddie Mac, and private securitization trusts
  • Nonbank Lenders and Finance Companies such as SoFi, Rocket Mortgage, Ally Financial, and Ford Credit
  • Hedge Funds and Private Credit Funds such as Citadel, Bridgewater Associates, Oaktree, and KKR

Together, these institutions supply credit and liquidity to the real economy while introducing interconnectedness, leverage, and opacity that can amplify systemic vulnerabilities.

Liquidity Transformation Explained

Liquidity transformation occurs when institutions fund illiquid, long-term assets with short-term, liquid liabilities.

Examples include:

  • Banks funding 30-year mortgages with short-term deposits.
  • Money market funds offering daily redemption while investing in short-term debt instruments.

This mechanism supports economic growth by converting savings into investment. However, it also exposes the financial system to liquidity risk: when investors withdraw funds simultaneously, institutions may be forced to sell assets quickly at discounted prices, triggering broader market stress.

Key Risks

The risks within the NBFI system can be subtle and hard to detect, echoing Jamie Dimon’s “cockroach” analogy, which warns that isolated credit failures may signal deeper, hidden fragilities beneath seemingly stable markets.

  • Run Risk: Sudden, large-scale investor withdrawals such as money market fund redemptions or margin calls on leveraged funds.
  • Fire-Sale Risk: Forced liquidation of assets at distressed prices, as seen during the 2008 global financial crisis and the March 2020 market freeze.
  • Contagion Risk: Liquidity or solvency stress at one institution spreading rapidly through interconnected funding and derivative channels.

Private Credit & Hedge FundsBlackstone, Apollo, Citadel, OaktreeLeveraged lending and alternative financing

The U.S. NBFI sector is the largest in the world, reflecting a deep reliance on market-based finance rather than traditional bank credit.

Lessons from the 2008 Subprime Crisis

Many vulnerabilities in today’s NBFI ecosystem resemble those that triggered the 2008 financial crisis, though the sources have evolved. Then, the epicenter lay in banks and mortgage originators. Today, it increasingly lies within private credit, structured lending vehicles, and leveraged investment funds, as illustrated by recent defaults such as First Brands and Tricolor Auto, which highlighted rising stress among nonbank lenders.

2008 Subprime CrisisModern NBFI SystemCommon Risk
Subprime mortgage securitization with weak underwritingPrivate credit and structured lending fundsCredit risk mispricing
Opaque CDOs and complex derivativesCLOs, ABS, and structured private fundsOpacity and leverage
Short-term funding of long-term assetsRepo financing and MMF liquidity mismatchMaturity mismatch
Bank and insurer interconnectednessDealer and fund interconnectednessSystemic contagion

Key difference: Today’s banks are more capitalized and better supervised, but much of the risk has migrated outside the banking perimeter into entities with lighter regulation and less transparency. The modern system is more market-based but remains vulnerable to funding shocks, margin spirals, and correlated losses during stress episodes.

The Bottom Line

NBFIs play a vital role in mobilizing capital, fostering innovation, and diversifying sources of finance. Yet their reliance on short-term funding, high leverage, and complex linkages makes them a recurring source of systemic risk.

As policymakers consider expanding investor access through initiatives such as the 2025 Executive Order, the challenge is to democratize investment opportunities without amplifying hidden leverage or liquidity mismatches.

NBFIs have become indispensable to modern finance, but as the 2008 crisis showed, when liquidity disappears, the line between banking and shadow banking can vanish almost overnight.

VIE Analysis: Understanding Variable Interest Entities in Investment Funds and Beyond

VIE Analysis: Understanding Variable Interest Entities in Investment Funds and Beyond A Variable Interest Entity (VIE) is a legal structure where control is not based primarily on voting rights. Instead, control may arise through contractual arrangements, financial support, or other mechanisms. VIEs are central to modern finance, used in securitizations, structured funds, and cross-border investments, but they also carry accounting complexity. How VIEs Are Identified (ASC 810-10) Under ASC 810-10 (Consolidation) , a legal entity is considered a VIE if any of the following are true: It has insufficient equity investment at risk to finance activities without additional support. Its equity holders lack the power to direct significant activities . Its equity holders do not fully absorb the entity’s expected losses or returns . Key idea: In a VIE, traditional equity investors do not control the most important decisions. The Primary Beneficiary Rule A company must ...

Credit Default Swap (CDS)

Image
What Is a Credit Default Swap (CDS)? A credit default swap (CDS) is a type of financial contract that works like insurance. It protects a lender or investor in case a borrower does not repay a loan. In a CDS, one party pays regular fees to another party, called the seller. In return, the seller promises to pay if the borrower defaults on the loan. For example, suppose a bank lends money to a company. To reduce its risk, the bank buys a CDS from another firm. If the company fails to repay the loan, the CDS seller pays the bank the agreed amount. If the company pays back the loan on time, the seller keeps the fee and nothing else happens. CDSs became widely known during the 2008 financial crisis. Many banks and investors used them to bet on or protect against mortgage loans. But because CDS contracts are not regulated like insurance, some firms took on too much risk. When large numbers of borrowers defaulted, many CDS sellers could not cover the losses, le...

Artificial Intelligence (AI) in Accounting

What Is Artificial Intelligence (AI) in Accounting? Artificial Intelligence (AI) in accounting means using smart computer systems to handle tasks that usually require human thinking. These systems can analyze large amounts of financial data, find patterns, and help with everyday accounting work like sorting invoices or checking for errors. For example, AI can scan and process hundreds of invoices in minutes. It can also spot unusual transactions that might point to fraud. Some AI tools can even give real-time insights on a company’s financial health, helping teams make faster and better decisions. It's important to know that AI does not replace accountants. Instead, it works alongside them. By taking care of repetitive tasks, AI allows accountants to focus on more complex work like strategy and financial planning. As businesses handle more data every day, AI is becoming a key tool in modern accounting. It helps teams work faster, reduces mi...
