One Asset Class’s AI Bull Case is Another’s AI Bear Case

CITI'S TAKE

Philip Dobrinov AC

Credit markets remain near recent tights, but we see a growing divergence +1-212-723-2118

between credit and equity risk exposures driven by the AI investment cycle. philip.dobrinov@citi.com

The AI bull case for equities is becoming a bear case for credit, as heavy

capex and structural leveraging for growth pressure balance sheets. This

decoupling is causing a decline in correlation and beta between CDX IG and

equities. Similar dynamics can be seen in hyperscaler and semi CDS.

Risk Rewind — Credit markets remain comfortably near recent tights, with recent

wobbles appearing more technical than macro. We see rising issuer dispersion

driving market moves. The widest five credits in CDX IG have sold off against the rest

of the index, highlighting idiosyncratic pressures rather than broad macro concerns.

Declining demand for tail risk protection further suggests investors are focused on

specific fundamentals as opposed to a broader macro tail risk.

Correlation Conundrum — Index-level credit and equity valuations are not yet

sounding alarm bells, given their proximity to recent high-water marks. Correlation

between CDX IG and the S&P 500 is declining along with equity/credit beta. This

divergence stems from differing risk exposures to the AI cycle, as credit markets are

weighed by deteriorating balance sheet leverage and free cash flow while equities

are buoyed by growth upside. Investors hedging equity longs with credit positions

will need to dynamically adjust, which should exacerbate volatility.
