JPMorgan: Rate Hikes Alone Won't Crush U.S. Stocks — The Real Red Line Is When Long-End Yields Break 5.5%
nashnova research
JPMorgan's Sept 10 global macro conference concluded that rate hikes alone won't end the US equity rally — the real pressure zone is the 10-year Treasury yield breaking 5.5%-6%, because AI capex and earnings growth are weakening the traditional rate-to-stock transmission.
Why does JPMorgan say rate hikes can't crush US stocks?
Core call: equities and long-end Treasury yields can rise together. The day after a 25 bp hike, the S&P 500 reclaimed its 50-day moving average and the Nasdaq led gains — AI chip stocks rebounded sharply.
This means → US equities are growing less sensitive to rates. AI, healthcare and services now make up a larger share of the economy, weakening the classic "hike → kill valuations" chain.
JPMorgan's equity strategy team targets 8,000 on the S&P 500 by year-end, citing intact earnings growth, light institutional positioning and valuations short of extremes.
Where exactly is the pressure line?
Markets used to flinch at 5% on the 10-year yield. JPMorgan argues that threshold has shifted — the zone that truly pressures equities is now 5.5%-6%.
In plain terms = the ceiling the market can tolerate has been raised, but a ceiling still exists.
Tech and growth stocks account for roughly 34% of the S&P 500 and are more sensitive to long-duration discounting. This means → the speed of the yield rise matters more than the absolute level: a gradual climb can be absorbed by earnings growth, but a rapid spike would hit valuations and corporate investment simultaneously.
How big is the AI capex wave?
The five US hyperscalers guided combined 2026 capex above $750 billion, projected to exceed $1.1 trillion in 2027; cumulative AI capex through 2030 could reach $5.5 trillion.
The funding side is keeping pace: investment-grade credit markets are expected to channel over $2.1 trillion to data centers over five years, with high-yield bonds and leveraged loans adding roughly $350 billion.
This reflects a cycle that high rates have not derailed. The binding constraints have shifted from demand to power, transmission, land and permitting — US grid load growth has already jumped from about 1% to 3%, while transmission approvals remain slow.
How does AI capex help stocks withstand higher rates?
JPMorgan estimates that if infrastructure keeps up, AI capex could add roughly 0.5 percentage points to labour productivity growth over the next one to two years.
In plain terms = AI spending is not just "burning cash" — it lifts the economy's output efficiency, which means companies earn more and can absorb higher interest costs.
That productivity boost is the core pillar of JPMorgan's "stocks and high rates can coexist" thesis.
What should worry investors more than rate hikes?
Fiscal deficits: long-end yields are rising globally, not just in the US — Europe is seeing the same. A New York Fed survey shows the 10-year term premium (the extra compensation investors demand for holding long-dated bonds) has climbed to roughly 125 basis points, signalling persistent concern over long-run fiscal sustainability.
Geopolitics pushing oil higher: JPMorgan's commodities team projects Brent crude at $87/barrel on average in 2027 under a "permanent conflict" scenario, well above the $64/barrel peace-scenario baseline — and oil is a direct inflation driver.
Affordability politics: a conference poll showed 75% of attendees expect a split Congress after the midterms, while cost-of-living pressure remains a top household concern — fuelling the impulse toward further fiscal expansion.
How should we read JPMorgan's conclusion?
The market's real question is not "hikes or rally" — it is whether earnings and AI investment can keep outrunning rate pressure.
As long as long-end yields rise in an orderly fashion, US equities can continue climbing alongside Treasury yields.
This means → the true risk is not the Fed hiking per se, but the moment yields sprint toward 5.5%-6% — at that point, earnings growth alone is no longer enough, and the balance breaks.
