Private credit grew by taking on riskier loans that banks shed after Dodd-Frank, making the core banking system safer. However, banks now provide wholesale leverage to these private credit funds with minimal due diligence, creating a new, less transparent concentration of risk.

According to PIMCO's CIO, post-crisis regulation heavily targets the last failure point (e.g., banks and consumer lending post-GFC). This makes previously regulated sectors safer while risk migrates to areas that escaped scrutiny, like today's non-financial corporate credit market.

The regional banking crisis and subsequent regulatory scrutiny forced many banks to exit complex, capital-intensive businesses like asset-based lending to smaller companies. This retreat has eliminated key competition for non-bank lenders, who can step in to fill the void without the same regulatory burdens.

The US financial system evolved through three phases: System 1 (1933-1999) separated commercial and investment banking, System 2 (2000-2008) deregulated and led to the GFC, and System 3 (post-2010) established new guardrails, spawning the private capital boom.

Regulatory leverage lending guidelines, which capped bank participation in highly leveraged deals at six times leverage, created a market void. This constraint directly spurred the growth of the private credit industry, which stepped in to provide capital for transactions that banks could no longer underwrite.

Regulations like Dodd-Frank shifted banks from being principal risk-takers to merely financing risk. During market dislocations, banks can no longer absorb selling pressure as they once did. This structural change creates a durable and profitable role for hedge funds to provide liquidity to distressed sellers.

The Basel III regulations, intended to de-risk the financial system by making risky lending expensive for banks, had an unintended consequence. The demand for risky loans didn't vanish; it simply migrated from the regulated banking sector to the opaque, unregulated private credit market, creating a new systemic risk.

The trend of companies staying private longer and raising huge late-stage rounds isn't just about VC exuberance. It's a direct consequence of a series of regulations (like Sarbanes-Oxley) that made going public extremely costly and onerous. As a result, the private capital markets evolved to fill the gap, fundamentally changing venture capital.

The migration of risk-taking from banks after the financial crisis spawned three major, distinct industries. Private credit absorbed bank lending, proprietary trading firms took over market-making, and multi-strategy hedge funds replicated the activities of internal proprietary trading desks.
