Goldman Sachs: Move Down the Credit Rating Spectrum — BBB Over AA, B Over BB
Nashnova编辑部
Goldman Sachs said Thursday that BBB-rated corporate bonds have outperformed AA and A in both total and excess returns, recommending investors move down the rating curve in both investment-grade and high-yield — while cutting the lowest-rated CCC tier.
What is wrong with high-rated bonds?
AA in investment-grade and BB in high-yield are the two largest buckets by issuance — but they share a weakness: long duration and thin spreads.
This means → when rates rise, these two tiers take the biggest price hit; their slim spread cushion gets overwhelmed first.
In plain terms = the higher the rating, the more exposed to rate moves — not because the issuer might default, but because the spread earned is too thin to absorb interest-rate swings.
Why has BBB actually done better?
Goldman's data show BBB bonds beat AA and A on both total and excess returns — across USD and EUR markets alike.
This reflects a counterintuitive reality: in a market obsessed with "quality," the tier one notch lower delivers better risk compensation thanks to a thicker spread.
Goldman had already favoured BBB in USD investment-grade. It now extends the call to EUR markets, arguing that AI-related high-grade bond supply will accelerate in Europe and further erode high-rated value.
High-yield too — B over BB?
Goldman shifted its high-yield preference from BB down to B.
The logic mirrors investment-grade: BB faces persistent supply headwinds — too much new BB issuance is flooding the market and compressing returns.
This means → investors willing to take one more notch of risk by buying B-rated debt pick up meaningfully better spread compensation.
What about CCC — doesn't it offer the widest spread?
CCC spreads are indeed eye-catching, yet Goldman cut the tier from neutral to underweight.
The firm wrote: this cohort is "highly idiosyncratic and requires careful single-name credit selection."
In plain terms = you cannot buy CCC as a basket — the gap between the best and worst names is enormous, and buying blind invites blow-ups.
What is the core bet behind this strategy?
The entire framework points one way: under the twin pressures of supply and rate sensitivity, mid-to-low-rated bonds offer more attractive risk compensation.
One critical assumption underpins it all: whether AI-related bond supply actually accelerates as expected — if high-grade AI debt does not flood in, the supply pressure thesis weakens and the high-rated disadvantage shrinks.
This reflects the essence of Goldman's call — a structural bet not on credit deterioration, but on asymmetric supply-demand impact across the rating spectrum.
