Muzinich’s Greil-Castro: Short-Term Corporate Bonds Offer Higher Yields Than Long-Term Sovereigns

Tatjana Greil-Castro, Global Head of Investments at Muzinich & Co., emphasizes that the allure of higher yields from long-term sovereign bonds does not outweigh the risks of volatility and duration mismatch. Her focus is on Muzinich’s Enhanced Yield Short-Term Fund, which invests in corporate bonds maturing within two years, with a portfolio size of nearly €10 billion. The fund’s strategy prioritizes predictability and lower default risk through a 60% allocation to investment-grade bonds and a selective exposure to high-yield segments, primarily in the BB rating tier rather than the riskier B category. ‘The predictability of returns from long-term sovereign bonds is low,’ Greil-Castro says, noting that their duration exposes investors to significant interest-rate risk and volatility. ‘Cash and money market funds are often overlooked as safer alternatives, offering returns that outpace inflation,’ she adds, while acknowledging that corporate bonds carry credit risk but mitigate it through short maturities and rigorous due diligence. ‘Companies cannot operate as irresponsibly as states,’ she argues, contrasting the fiscal discipline of corporations with the structural deficits of many sovereign borrowers. ‘The market’s current pricing of corporate bonds reflects a recognition that companies are stronger debtors than many governments,’ she asserts, citing examples like Italy’s banks, where corporate bonds may offer better risk-adjusted returns despite rating limits. Greil-Castro also questions whether the U.S. Treasury market’s recent stress signals—such as the government’s limited purchases of long-term bonds—indicate systemic fragility. ‘The U.S. government’s approach to debt management is increasingly desperate,’ she says, warning that reliance on artificial growth drivers like artificial intelligence (AI) may not resolve structural deficits. While she acknowledges AI’s potential to boost productivity, she argues that its impact would need to be substantial to offset the high primary deficits and debt dynamics. In the bond market, tech giants like Amazon and Alphabet have recently issued bonds at higher spreads, reflecting rising risk perceptions. Greil-Castro notes that Muzinich avoids such issuers unless they meet its risk criteria, emphasizing the importance of short maturities to assess corporate health. ‘The current term premium is insufficient to compensate for the risks of long-term bonds,’ she concludes, underscoring the appeal of her fund’s strategy amid rising sovereign yields and evolving market dynamics.
