What is Private Credit

Private Credit lending happens on a bilaterally negotiated basis where lenders work with borrowers to create bespoke solutions that address companies’ unique needs. By engaging directly with borrowers, Private Credit lenders have more flexibility to negotiate terms, covenants, and pricing, which can lead to better protections and higher yields for investors relative to traditional fixed income instruments.

The largest segment of Private Credit is Direct Lending, which focuses on senior secured loans to middle and upper middle-market companies. These loans typically  feature regular cash interest payments and sit at the top of the capital structure, which means they hold the highest priority in the capital structure above other debt and equity.

The Evolution of Private Credit

When a company needed a loan to finance operations, expansion or growth, it used to turn to banks. That changed in the last two decades, driven by a combination of industry consolidation and post-2008 financial crisis regulatory changes that made private, sub-investment grade loans economically unattractive holdings on bank balance sheets.

Banks’ remaining lending capital allocation has increasingly focused on larger companies with other revenue adjacencies. Mid-sized companies, generally those with up to $1 billion in revenue, have simultaneously faced declining access to the two primary sources for Public Credit – broadly syndicated loans and high yield bonds – as both markets have gravitated toward larger offering sizes  and bigger companies. Meanwhile, demand for private debt financing among middle-market companies have increased substantially, as companies stay private longer and the role of private equity investment firms continues to grow. Non-bank players such as Private Credit investment managers, insurers, and finance companies, have stepped in to fill the void, seizing on the opportunity to lend directly to middle market companies. As a result, Direct Lending has grown and matured significantly over the last two decades. The current Private Credit market is estimated to be more than $2 trillion, surpassing the size of the leverage loan and high yield markets.1 The Private Credit market is expected to continue to scale, more than doubling to $4.5 trillion by 2030.1

As Private Credit has grown, so has its importance in driving economic growth and business development. By providing financing to companies that may not have access to traditional bank loans or public debt markets, Private Credit can help businesses to hire, invest, innovate, and scale. This is particularly important for middle-market companies, which collectively represent one of the largest contributors to employment and economic output in the United States. Without access to Private Credit, many of these businesses could face significant constraints on their ability to grow, compete, and create jobs.

Private Credit’s Value Proposition for Borrowers

The attractiveness of Private Credit for potential borrowers is a key factor driving its growth. Both corporate borrowers and private equity sponsors have demonstrated a willingness to pay the generally higher costs of Private Credit relative to the public market alternatives in order to take advantage of what they perceive as several attractive relative characteristics, including:

Speed and Certainty of Execution. Public markets can be affected by macroeconomic volatility, causing dislocations and pull-backs in lending. Private Credit funding tends to be less affected, making it more available while providing less variation in terms throughout market environments. In addition, Private Credit deals are often executed more efficiently because they typically involve a single or small group of lenders compared to public markets, which could require input from hundreds of lenders.

Customization and Flexibility. Private Credit deals offer customized terms to meet the specific needs of a company rather than the standard terms offered by public markets. The flexibility to draw capital down over time and align capital with a company’s growth needs is an example of a potential key feature in Private Credit deals.

Heightened Degree of Confidentiality. Private Credit transactions are typically negotiated with a single or limited group of counterparties, resulting in enhanced confidentiality throughout the transaction process as opposed to public credit markets. Companies are often sensitive to public disclosure considerations and may pursue Private Credit solutions to achieve greater discretion and confidentiality.

A Partnership-Oriented Lending Relationship. Deals with Private Credit managers come with access to their expertise, insights, and commercial network.

Private Credit’s Value Proposition for Investors

Private Credit strategies offer several potentially attractive features to prospective investors, including:

Premium Yield and Returns. Private Credit has historically offered higher yields than other income-oriented investments such as traditional fixed income alternatives and high dividend-paying stocks. These higher yields have not historically been offset by higher realized losses. Private Credit has generated yields 3.7% higher than broadly syndicated loans and 4.0% higher than high yield, on average, over the last 10 years.2,5,6 In addition, Private Credit has achieved total annualized returns that are 3.6% higher than broadly syndicated loans and nearly 3% higher than high yield over the same period.2,5,6

Competitive Yields across Assets (10-Year Average)3

Seniority and Security of Loans. Direct Lending predominantly focuses on senior secured loans. Investments are generally secured by the borrower’s cash flows, physical and financial assets, and tend to be very senior in the capital structure – ahead of equity and any subordinated debt. Loan amounts are typically only 30% to 60% of total asset value, creating a substantial cushion against any potential impairment.

Strong Contractual Protections. Private Credit loans also typically carry a robust set of contractual protections for the lender, called covenants. In addition to the contractual obligation to pay regular interest and repay loan principal on a set schedule, covenants often limit the total amount of debt a borrower can have outstanding and prevent the borrower from incurring additional debt that is more senior to the direct loans or reducing the collateral securing the direct loans. These types of protections can help to create downside protection while also functioning as early indicators of weakening borrower performance.

Floating Rate Structure. Floating rate loans – where the cash coupon of the loan is reset as interest rates change – typically account for most Direct Lending portfolios. This benefits investors in elevated interest rate environments and should better insulate investors in sustained inflationary periods compared to other fixed income instruments and equity. At the same time, these loans are often structured with reference interest rate floors that provide additional yield protection in very low interest rate environments. Investors interested in gaining exposure to Private Credit in their portfolios should consider evaluating the business development company (BDC) as a potential investment structure.

Private Credit’s Potential Fit in Investor Portfolios

Incorporating Private Credit into a diversified portfolio may improve overall income, reduce reliance on public market performance, and enhance resilience across economic cycles. For individual investors, this creates an opportunity to build portfolios that are not only return-oriented but also more balanced and durable. As a result, an allocation to Direct Lending may be worthy of consideration for investors who are:

  • Focused on income and current yield
  • Interested in portfolio diversification
  • Concerned about the impact of elevated interest rates or inflation

For investors with a traditional 60% equity and 40% fixed income allocation, private credit can serve as a complementary component that enhances both return and risk characteristics. By introducing an asset class with a lower correlation to public equities and bonds, portfolios may benefit from improved diversification and reduced overall volatility. Looking at a long-term investment horizon of the last 20 years, portfolios that included a 10% allocation to direct lending outperformed and had lower volatility than traditional 60/40 portfolios.

Adding Direct Lending to a Diversified Portfolio Would Have Improved Return and Risk Efficiency10

In our view, the steady income, reduced mark-to-market fluctuations, and differentiated risk exposures create a more efficient portfolio with improved risk-adjusted returns over time.

Risks and Other Considerations

Investments in Private Credit strategies carry a number of potential risks. The investments of a Direct Lending fund have credit risk to the underlying borrowers, substantially all of which are sub-investment grade or not rated. These investments may be subject to mark down or loss of capital. In addition, most Private Credit funds have the ability to employ leverage that could ultimately result in the magnification of any potential investment losses.

The underlying investments of Direct Lending strategies are illiquid. Depending on the type of Private Credit fund and its terms, an investment in the fund may have limited or no liquidity; therefore, investors may not have the ability to liquidate their investment when desired or at all. As a result, Direct Lending is not a suitable investment for investors who cannot absorb losses or who require regular or immediate liquidity. Investments in Direct Lending funds are typically subject to fees and expenses, which lower the fund’s investment returns to shareholders and are also subject to potential conflicts of interest.

Before making the decision to invest in a Private Credit strategy, investors should consult their financial, tax, and accounting advisors and read the fund’s prospectus carefully for a full list of risks associated with an investment in the fund, as well as a description of any fees and expenses.

Conclusion

Private Credit is poised for further growth as an asset class. Historically, Direct Lending strategies have provided investors with attractive risk-adjusted returns, predominantly driven by high cash yield. We believe the historically consistent high-single digit returns, low relative volatility and correlation with traditional investments, and potential for relative resiliency in the face of elevated interest rates and / or sustained inflation make Private Credit strategies worthy of consideration as part of an income-focused investor’s diversified investment portfolio.
