The market has stopped pricing credit risk.

The market has stopped pricing credit risk.

SPY’s sensitivity to wider high yield spreads is now the shallowest in a year.

Quant Insight’s MFERM model shows SPY’s credit beta at -0.355, a +2.1σ reading versus its own trailing one-year history.

Plain English: equities are behaving as if credit risk does not really matter.

That usually happens after a strong run.

When we sort history by SPY’s credit sensitivity, the pattern is clear:

  • The shallower the credit beta, the stronger the trailing year

  • But the forward year gets weaker


  • The average forward 1-year return falls from +22.6% in the deepest credit-beta regime to +10.4% in the shallowest

  • The chance of a negative year rises from 4% to 26%

That does not make this a sell signal.

The left tail has thickened.

That is the important point.

Markets are not obviously priced for a bad outcome. They are priced as if the bad outcome is unlikely to matter.

History says that is when fragility builds.

The lesson from Qi’s model:

The best of the easy run may be behind us.

Not because equities must fall.

But because the market is now carrying credit risk it is not being paid to carry.

For investors, that argues for owning convexity rather than cutting exposure outright.

The median outcome can still be fine.

The tail is where the risk has moved.
