S&P 500 vs Treasury Yield Spread
The Kobeissi Letter's bar chart drew 216K views on X: 0.9x its typical post and #21 of 48 The Kobeissi Letter charts we track by views. Read Oct 14, 2026.
We are witnessing a historic shift.
Why it spread
This post spread because it landed on a hot topic that week and came from an independent author, with the account @KobeissiLetter posting on 2026-10-13 about a historic shift in the annual spread between the S&P 500's earnings yield and the 10Y Note yield, which was down to -1.5 percentage points, its lowest since 2009, and had fallen -440 basis points since 2022, its largest 5-year decline since the 1970s, drawing 640 likes, 93 reposts, 13 quotes, 146 saves and 101,330 views.
What worked
- The post framed a single striking number, the -1.5 percentage point spread at its lowest since 2009, as a historic shift.
- The post stacked a second supporting number, the -440 basis point fall since 2022 as the largest 5-year decline since the 1970s, to reinforce the scale.
- The bar chart showing the S&P earnings yield spread over the Treasury yield fluctuating historically gave the claim a visual anchor, and the post carried a source line and branding.
What to borrow
We could take one hot topic of the week and pair a single headline number with one longer-run comparison, then show it as a simple bar chart of our own data with a clear source line.
Careful
Do not copy the framing that a single spread or decline is destiny, and do not over-read the engagement: the quote rate was below average, and the spread, likes, reposts, quotes, saves and views are specific to this account and this week.
