50 Years of Data: Rising Rates Hurt Stocks, but Economic Growth Is the Key

The US 10-year yield has broken above 5%, but a study spanning 1970–2026 shows rising rates alone don't kill equities — the direction of economic growth does.
The 10-year yield hit 5% — should equity investors panic?
The US 10-year Treasury yield recently crossed 5%, reigniting debate over the outlook for stocks.
A study covering S&P 500 excess returns from 1970 through mid-September 2026 offers a different read: rising yields do not automatically spell trouble for equities.
This means → judging stocks by the level of rates alone is working with only half the picture.
Same rising rates — why do outcomes diverge so sharply?
The study sorted every month of rising yields into two buckets: economic growth accelerating, or growth slowing.
Growth accelerating: even with yields climbing, cumulative equity excess return reached roughly +200%.
Growth decelerating: the same rising-rate backdrop produced a cumulative drawdown of about -150%.
In plain terms = when the economy is expanding and companies earn more, stocks can absorb higher rates; when growth is fading, higher rates become the straw that breaks the camel's back.
What if you lump all the months together?
Blending every rising-yield month regardless of growth direction yields a cumulative excess return that is only marginally positive.
This reflects the near-perfect offset between the large gains in acceleration periods and the large losses in deceleration periods.
This means → the blanket claim that "rising rates are bad for stocks" is neither fully right nor fully wrong — it simply drops the most critical variable.
What does this mean for today's market?
The 10-year yield is at 5%, but history's message is clear: the key is not the rate level itself but whether economic growth is strengthening or weakening.
If growth momentum is still accelerating, equities have historical precedent for digesting high rates and continuing to climb.
If growth is already slowing, the drag from elevated rates is likely to bite in full.
In plain terms = stop fixating on the rate number and answer one question first: is the economy still expanding? That answer determines whether 5% yields are a headwind or a manageable cost.
