Given the outlook for increased debt issuance from large US corporations to fund expansion, Morgan Stanley sees better opportunities in assets less exposed to this trend. They favor high yield bonds over investment grade and believe European credit may outperform as it lags the US "animal spirits" theme.

In 1935, amidst massive economic uncertainty following the Great Depression, a new AA-rated corporate bond yielded just 70 basis points over Treasurys. This historical precedent, nearly identical to today's spreads, shows that low credit spreads are not necessarily a sign of complacency and can persist even if economic conditions worsen, challenging typical risk-pricing assumptions.

Top asset managers have significantly higher margins, better growth prospects, and fewer credit or regulatory risks than banks. Despite this, the market can value them at lower multiples than many banks, creating a potential relative valuation opportunity.

A market anomaly exists where large-cap banks trade at higher multiples (12x earnings) than smaller, faster-growing banks (8x earnings). This is driven by massive passive investment flows into large-cap indices and the perception that large banks are 'too big to fail.'

While mortgage-backed securities (MBS) have rallied and are at five-year tights, the trade is not over. Investment-grade corporate bonds are at 20-year tights, making MBS still look cheap on a relative value basis. The strategy now is to tweak the trade rather than abandon it entirely.

With credit curves already steep and the U.S. Treasury curve expected to steepen further, the optimal risk-reward in corporate bonds lies in the 5 to 10-year maturity range. This specific positioning in both U.S. and European markets is key to capturing value from 'carry and roll down' dynamics.

The sheer volume of debt needed to fund AI infrastructure will likely widen spreads in investment-grade bonds and related ABS. This supply pressure creates an opportunity for outperformance in insulated sectors like US high-yield and agency mortgage-backed securities.

While currently unattractive, a future, inevitable credit spread widening event (e.g., IG to 165-185 bps, HY to 600-800 bps) will kick off a five-to-ten-year 'golden age' for credit, where corporate bond returns could rival or even outperform equity markets.

A surge in investment-grade bond issuance to fund AI capital expenditures will insulate the high-yield market. This technical factor is expected to drive high-yield bond outperformance versus higher-quality corporate bonds, which will face supply pressure.
