SocGen: U.S. Treasury Yields Rising to 5.5% Would Hit Equity Valuations
nashnova research
SocGen's global asset-allocation head Alain Bokobza warns that a 5.5% ten-year Treasury yield is the point where borrowing costs overwhelm earnings growth — the current 4.78% leaves roughly 72 basis points of cushion before equities come under real pressure.
Where does the 5.5% line come from?
Bokobza defines 5.5% as the threshold where "equities start to come under attack" — beyond it, the cost of corporate borrowing rises faster than profits can grow, and stock valuations buckle.
This means → every tick higher in yields forces the market to discount future earnings a bit more; 5.5% is where the discount grows too large for even strong earnings to offset.
The ten-year yield currently sits at 4.78%, about 72 basis points below that red line.
Why haven't stocks fallen this year?
Bokobza notes that global earnings expectations were revised sharply higher this year, keeping the equity risk premium intact even as yields climbed.
In plain terms = rates went up, but so did profit forecasts — the two cancelled each other out, so stocks are no more expensive than they were in January.
His explicit warning: once yields breach 5.5%, earnings upgrades can no longer keep pace with rising borrowing costs — the hedge breaks down.
Why do yields keep climbing?
Bokobza frames the yield rise as a "long-term structural increase" in nominal GDP, not a short-term swing.
Three forces are stacking up: ① sustained fiscal expansion in Germany, Japan, and elsewhere; ② stubbornly persistent inflation; ③ surging capital demand from AI infrastructure buildout.
This reflects a deeper signal: the high-rate trend that began in the early 2020s is unlikely to reverse soon — the low-rate era is probably over.
Can central-bank rate cuts change the picture?
Bokobza expects upcoming Fed and ECB rate cuts to be "modest" — not enough to break the current economic cycle or suppress inflation expectations.
This means → don't count on central banks pulling rates back down — the cuts are too small to offset the structural push.
How do other banks draw the danger line?
JPMorgan's Grace Peters and Barclays' Emmanuel Cau have both flagged 5% as a psychological threshold, saying investor anxiety over equity impact rises sharply once it is reached.
Bokobza's 5.5% threshold pushes the warning line another 50 basis points higher — implying that the market can absorb more yield pressure than peers expect.
In plain terms = a 72-basis-point cushion sounds comfortable, but how long it lasts depends on two things: how fast yields rise, and whether earnings forecasts can keep up.
