In the wake of the 2008 financial crisis, regulators implemented a suite of new rules aimed at making the banking system safer. A recent research paper from the Bank for International Settlements (BIS) sheds light on an important, and perhaps unintended, consequence of these reforms: the explosive growth of the private credit market.
The study reveals that post-crisis liquidity regulations, specifically the Liquidity Coverage Ratio (LCR), have been a major driver of the shift in lending away from traditional banks and into the hands of non-bank lenders, such as private credit funds. Here are the key takeaways I noted after reading the research paper.
The Scale of the Shift: Private Credit Growth
The chart below illustrates the dramatic growth of loan assets held by non-bank financial institutions, a key proxy for the private credit market. The steep and sustained rise, particularly in the years following the adoption of the LCR (2014), visually captures the trend analyzed in the BIS research paper.
The Great Lending Shift
The core finding of the paper is clear: in areas with a heavy presence of large banks subject to the LCR, private credit volumes grew significantly more than in other areas.
When the LCR was introduced, it required banks to hold more high-quality liquid assets (HQLA). To meet these requirements, banks scaled back on holding illiquid loans for small and mid-size firms. This created a vacuum in the market, which private credit funds swiftly stepped in to fill.
The study used the leveraged loan market as a control group to prove this point. Leveraged loans are typically originated by banks but then quickly sold off to other investors, so they don’t weigh on a bank’s balance sheet in the same way. The research found that this market was unaffected by the LCR. This contrast reinforced the conclusion that the growth in private credit was a direct result of regulatory constraints on banks’ own balance sheets, not a general increase in loan demand.
A Safer System, Or Just a Different One?
A central question raised by this shift is whether it has truly made the financial system safer. The paper suggests that from one perspective, the answer is yes. However, it also supports a more nuanced view: risk rarely disappears; it simply moves and changes form.
On one hand, the shift has likely reduced a specific type of vulnerability. Private credit funds are typically funded by long-term capital from investors, which is locked in for years. This is a much more stable funding source for long-term, illiquid loans compared to a bank’s short-term deposits. This better matching of assets and liabilities reduces the “maturity mismatch” risk that makes traditional banks vulnerable to runs.
On the other hand, this doesn’t mean risk has vanished from the economy. As many have argued, the 2008 financial crisis demonstrated that transferring risk away from banks does not necessarily eliminate it. Prior to the crisis, former Fed Chair Alan Greenspan argued that derivatives helped transfer risk to those most capable of bearing it, but he later acknowledged that the crisis exposed a "flaw" in his understanding of how the financial system would manage those risks. The crucial question then becomes whether the non-bank entities taking on this risk are truly equipped to manage it.
Important Considerations for the New Landscape
While the findings are positive in some respects, the paper adds a few crucial caveats that align with this cautious view of risk.
First, this shift does not eliminate systemic risk entirely. The analysis doesn’t fully account for factors like deposit insurance or central bank backstops. More importantly, it highlights the potential for new, unforeseen risks to emerge. For instance, risks can return to the banking system through the back door via the credit lines that banks provide to private credit funds. If these funds face distress, they could draw down on these lines, transmitting stress right back into the regulated banking sector.
This creates a new channel for financial contagion, reminiscent of how derivatives were once thought to distribute risk before 2008 but instead amplified risk throughout the system.
Conclusion
The BIS paper provides
compelling evidence that regulations designed to make banks safer have the
profound side effect of fueling the private credit boom. This has fundamentally
reshaped the world of lending. While the shift may have created a more
resilient financial ecosystem by addressing specific liquidity risks, it also
underscores a timeless lesson in finance: risk is rarely destroyed, only
redistributed. The stability of the system now depends on a new set of factors
and a new web of interconnectedness that we are only just beginning to fully
understand.
