Structure of the Private Debt Market

The structure of the Private Debt market
Private Debt — an asset class representing lending to companies directly or through specialized funds, bypassing public bond markets. Over the past 15 years, this market has grown from $200 billion to over $1.5 trillion AUM, becoming one of the most dynamically developing segments of alternative investments.

Market growth drivers

Regulatory factors (Basel III/IV)
After the 2008 financial crisis, regulation of the banking sector tightened significantly:

  • Increased capital requirements: RWAs for leveraged loans rose from 50% to 100-150%
  • Leverage ratio constraints: Limitation on the ratio of assets to capital
  • LCR and NSFR: Liquidity requirements decreased banks’ appetite for long-term loans
  • Leveraged lending guidelines: Restrictions on lending with Debt/EBITDA > 6x

Result: Banks reduced middle market lending by 30-40%, creating a vacuum that was filled by private credit funds.

Institutional demand

  • Low rates (2010-2021): Yield search in a zero-rate environment
  • Illiquidity premium: Premium of 200-400 bps over public markets
  • Diversification: Low correlation with traditional asset classes
  • Income predictability: Floating rate protection from rising rates

  • Manager selection: Track record through a full cycle is critically important
  • Floating rate exposure: Understanding the impact of rates on borrowers
  • Vintage diversification: Allocation of commitments across years
  • Liquidity planning: Private debt is less liquid than it appears
  • Fee awareness: Understanding total cost of ownership
