Attractive opportunities in investment grade private credit

Investment grade private credit is a capital efficient asset class that can offer investors the potential for excess returns, lower downgrades and defaults and provide a natural hedge for long-term liabilities.

After a slowdown in issuance that mirrored public markets during the first month of the global pandemic, investment grade private credit markets sprang back to life in late April and May. Investors were able to source attractive deals at significant yield premiums to similarly rated public bonds. Additionally, active managers continue to exploit market dislocations and generate strong risk-adjusted returns for clients by adding high-quality assets at historically compelling spread levels.

We believe there is a long-term role for both public and private fixed income in investors’ portfolios. Investment grade private credit complements public credit by adding additional spread premium and diversification while retaining a high correlation to long-term financial liabilities.

What is investment grade private credit?

Investment grade private credit¹ refers to loans and debt securities issued by companies or entities outside of the public capital markets. Investors are primarily institutions such as insurance companies and pension funds.

  • Investment grade private credit instruments are similar to public debt. They typically have durations that range from five to 30 years, often include collateral and financial covenants and are available across the rating spectrum.
  • Investors are paid a spread premium over comparable public bonds because these transactions are more customized and less liquid.
  • The private placement issuer base includes public and private corporate issuers and spans major sectors (industrials, utilities, financials).
  • Annual issuance in the investment grade private credit market is $70 to $100 billion per year and growing, with the U.S. representing about 60% of annual volume.

Why investment grade private credit?

The strength, durability and growth of the investment grade private credit market reflects the wide range of benefits afforded to both issuers and investors.

Benefits to borrowers of investment grade private credit issuance:

Flexible terms

Features and deal terms of investment grade private credit can be highly customized to meet the needs of the issuer and include non-standard maturities, delayed or multiple draw periods and custom amortization.


Issuers of investment grade private credit can bypass the time and expense associated with public disclosure and registration requirements, allowing private issuers to maintain confidentiality.

Knowledgeable investor base

Most investment grade private credit investors are affiliated with larger investment management organizations with dedicated analysts capable of underwriting unique or complex transactions that would be difficult to execute in the public market. Issuers also value the ongoing relationship with private investors as a source both of capital for growth and structuring expertise.

Benefits to investors of investment grade private credit markets:


The investment grade private credit market offers investors the opportunity to invest in unique transactions and issuers not available to public bond investors.

Higher spreads

A combination of the illiquidity premium and bespoke nature of investment grade private credit placements relative to public bonds allow investors to capture a spread premium over comparable public issuers, as well as the potential for additional income associated with consents, amendments and, in some cases, coupon increases.

Better lender protections

Investment grade private credit investors benefit from deal structures that are typically more robust than public market transactions, including collateral and financial covenants that allow investors to get back to the negotiating table in the event of credit deterioration. Investors also benefit from direct access to management along with access to information not available to public investors.

Applications for Defined Benefit Plan Sponsors

Most plan sponsors are comfortable with the role private assets play within the growth-oriented portion of their portfolio, but typically we have seen less adoption within the liability-hedging portion. Hedging assets are typically focused on public corporate and treasury bonds, however as plan sponsors look for ways to add diversification and additional yield to their portfolios without taking on excess credit risk, investment grade private credit has become an attractive option.

Investment grade private credit complements traditional fixed income mandates in a well-rounded LDI program. Insurers have historically accessed this asset class to back long-term liabilities, and we believe a similar opportunity exists for plan sponsors to earn extra yield while still maintaining a strong correlation to plan liabilities.

Additional yield/diversification to keep pace with downgrade-immune liabilities

Pension plan liabilities are essentially “immune” to downgrades or defaults in the discount rate used to value them. This presents challenges for plan sponsors looking to construct fixed income portfolios that can keep pace and maintain funded status. Typically, plan sponsors have looked down the quality spectrum to increase potential returns and add diversification as they seek to build robust hedging portfolios. Investment grade private credit can provide additional yield without sacrificing quality.

Preparing for hibernation/termination

Investment grade private credit has been a staple of life insurers hedging strategies for long-term liabilities and the additional yield has contributed to attractive pricing for plan termination strategies. Plan sponsors can access these benefits directly through investing in similar strategies, while also building a portfolio that is attractive to life insurers should they decide to pursue a buyout in the future.

Correlation to liability discount rates

Investment grade private credit is an attractive asset class for plan sponsors looking to hedge high-quality liability discount rates. The correlation between investment grade private credit yields and AA-rated corporate bond yields reflects the high quality nature of the asset class and the joint dependence on underlying treasury yields. Typically, investment grade private credit yields provide greater stability in more volatile environments as they react more slowly to changes in the market.

Applications for Defined Contribution Plan Sponsors

For defined contribution (DC) plan sponsors, investment grade private credit can provide an appealing middle ground between traditional corporate bonds and higher yielding “plus” sectors. With an increasing number of strategies available that fit within the DC regulatory framework, there are opportunities for plan sponsors to incorporate this attractive asset class into their portfolios.

Enhancing core plus mandates

Plan sponsors looking to add additional yield to their core or core plus portfolios can allocate assets from traditional public bond strategies towards investment grade private credit. Plan participants can benefit from the additional yield and lower losses relative to traditional investment grade public bonds, without sacrificing credit quality within their bond portfolios.

Increased portfolio diversification

Plan sponsors looking to enhance diversification and reduce volatility in their portfolios can utilize investment grade private credit alongside other “plus” sectors. Relative to these sectors, investment grade private credit exhibits much lower correlations to equities, high yield and emerging market debt. This is intuitive given the very different underlying risk factors that drive investment grade private credit versus these other asset classes. This added diversification benefit within a core plus mandate can provide protection for participants in times when equity markets are under greater stress.

Accessibility through daily valued strategies

Daily valued investment grade private credit strategies allow plan sponsors to allocate to the asset class within their defined contribution plans. Typically, individual deals are valued on a monthly basis and then updated for daily market movements to fit within a daily valued DC framework. Similar to other core plus investment guidelines, limiting the allocation to 20% should ensure that the top-level bond fund or target date fund has sufficient liquidity on a daily basis while maintaining the benefits of the allocation.

Applications for Insurance Companies

The attractive capital efficient yields have made investment grade private credit an integral component of life insurer’s portfolios, and in recent years, there has been significant adoption within the Property and Casualty (P&C) segment as well. P&C insurers look for ways to add yield without taking on additional credit risk or exposing themselves to regulatory charges, and investment grade private credit can effectively deliver these characteristics to the portfolio.

Capital framework treatment

Investment grade private credit is typically treated like any other fixed rate corporate debt security from an accounting and capital perspective. On a capital-adjusted basis, investment grade private credit presents insurers the opportunity to add attractive yield to their portfolios at a similar capital charge to traditional public debt.

Statutory and Regulatory Treatment

From a statutory filing perspective, investment grade private credit is disclosed on Schedule D Part 1 (Bonds) as an Amortized instrument, in line with traditional public debt. Similarly, the Risk Based Capital charges for investment grade private credit correspond to a NAIC 1 – 2 bond, depending on the rating.

Regulatory Modeling (AM Best BCAR, Moody’s, S&P)

About 80% of investment grade private credit deals have nationally recognized statistical rating organization (NRSRO) ratings, and the remaining balance is filed directly with the securities valuation office (SVO). In most cases, ratings agencies do not penalize investment grade private credit relative to traditional public fixed income. BCAR, Moody’s and S&P all treat investment grade private credit similarly to other fixed income securities that have a corresponding rating. However, Moody’s and S&P may apply a minor liquidity premium if they feel investment grade private credit allocations are excessive.

At SLC Management, we work with clients and consultants to manage liquidity concerns around private assets. Our investment process for insurers begins with a full review by our insurance solutions team. Stochastic modeling highlights areas of operational stress (reinsurance limits, CAT risk, and premium collection rates), measures the required portfolio liquidity and then assesses a client’s ability to harvest the illiquidity premiums available in private assets within a portion of their portfolio.
