Mega-bond-manager PIMCO has long championed market timing (aka relative value) as its value proposition in managing bonds. So, it is not surprising that the major business news outlets today featured PIMCO’s announcement that private debt is now overvalued, claiming that a 2% yield spread (their calculation) between private and public credit securities is insufficient to justify private debt allocations.1
Our own research finds no such yield anomaly. Instead, today’s yields are consistent with historical patterns that should allow private debt investors to earn a 9-10% total return over the next five years, or 5 percentage points above public debt investors.2
PIMCO’s pronouncement is also a reminder of the failed track record of those predicting market inflection points, both top and bottom. No investment organization, to our knowledge, has ever achieved long-term success based on that approach.3 Instead, investors should decide upon a long-term target allocation to private debt at some level appropriate for their objectives, diversify across the best lenders, and rebalance to their target over a market cycle. This has been the playbook for successful investing for private debt and all other asset classes.
Exhibit 1: Yield Comparisons for Private Debt (CDLI4), Public Credit (Morningstar LSTA US Leveraged Loan 100 Index), and 3-Month Treasury Bills

Exhibit 1 displays a current yield comparison for three broadly used indices reflecting private debt (CDLI), public credit (Morningstar LSTA US Leveraged Loan 100 Index), and cash (3-Month T-bills). Data is through June 30, 2024.
Several observations are worth noting:
- Absolute yields are currently elevated across the three indices, driven by high cash yields.
- Absolute yields are persistently higher and more stable for private debt, compared to public credit, consistent with the lower volatility of private debt returns, compared to public credit returns.5
- Spreads for both private debt and public credit are lowest (highest) when T-bill yields are highest (lowest).6
- The June 30, 2024 current yield spread between private debt and public credit equals 2.86%, which is below its long-term average but consistent with lower historical private-public spread when T-bill yields are high.
In summary, current and historical data does not undermine the private-debt-for-the-long-run investment thesis.7 Neither does it support the notion that private debt is currently overvalued.
