The real yield is acting as an influence on SPX500, and may be volatile in the near-term

  • SPX500


There is a relationship between the 10-year real rate and the SPX500. The correlation coefficient between the two is a robust -87%. I.e. they generally travel together but in opposite directions. This makes sense given the time value of money of the SPX500, where a lower real rate will tend to support the stock market.

The real rate has declined since its high of 2.61% for October 2023. This, in turn, has seen an appreciation in the SPX500 over the period. However, since the middle of December, the yield has levelled off (top red rectangle) and as such, the SPX500 has lost its momentum, and is tending to drift sideways, with only a slight upwards appreciation (bottom red rectangle).

Our opinion, and subject to correction, is that in the medium-to-longer term, the path of least resistance is down for the real rate, thereby supporting the SPX500. This is because inflation is moderating, and the Fed will likely cut rates this year.

However, in the short-term the direction may be more volatile.

Considering the real yield, the directional breakout from the top red rectangle (green arrows) will have an influence on the SPX500, given the strong correlation coefficient between the two. I.e. a higher yield will likely act as a headwind against the SPX500, whilst a breakdown in the yield will help support the stock index.
