Do Interest Rates Really Affect Stocks?
Interest rates seem to obviously affect stocks. But conflicting research casts doubt on how and how much they actually do.
I’m convinced that there are very few experts in investing.
There are plenty who see themselves as experts and plenty who are seen as experts.
Economics is a social science — yet one with the veneer of a mathematical science.
This invites misunderstanding — and exploitation.
If I had to give my son one non-obvious piece of financial advice, it might be: Beware of confidence in investing.
Humans are drawn to confidence. Confidence equates to competence in the deterministic world: the cave man confident about the location of the nearest water hole or game migration path was likely right.
Less so in stochastic social sciences like investing and business. It’s impossible to know many things (this is why Warren Buffett says that in business, any IQ points above 120 are wasted). Often, you just need a reasonably good idea, the willingness to endure some trial and error, and some luck.
But this doesn’t change the fact that the human mind is set up to really value confidence.
And in investing, we crave authority figures that, frankly, can’t exist. (Ditto for medicine.)
This creates a vacuum that “authority” figures who don’t quite have the authority they claim to step into to fill anyway. It’s human nature at work — theirs and ours.
I’ve personally felt torn on this, as a former “guru” on stocks. My public track record beat the market for all 10 years I advised on equities in the US and in the UK. Not just cumulatively (which would place me above 86% of professional managers), but every year.

From an optimization-of-James’-career standpoint, I should probably be standing on the rooftops trumpeting my record. I should be raising money for a big fund, because I’ve picked stocks better than most (and I outperformed with boring dividend stocks and fundamental research, to boot).
But I’ve been reluctant to assign a level of authority to myself that’s beyond what can really exist.
Anyway, returning to the here-and-now — and “experts” — we have a US Federal Reserve intent on lowering rates — the Fed says 3 cuts, and the market was predicting 6-7 until recently.
In a world following proper economic laws of physics, rising rates should slow down the economy, and ultimately, stocks. And lowering rates should do the opposite. It’s weird and wrong if they don’t.
I believe much of the existing research skews this way, but it’s surprising how much experts disagree on this (and, likely, how much conclusions can be swayed by choice of data periods).

Do Interest Rates Move Stocks – or Not?
Investors, we have a discrepancy.
In one corner is the Fed, which expects to cut its Fed Funds rate three times in 2024 (cuts tend to happen in quarter-point increments). This would total a 0.75 percentage point reduction to the target Fed Funds rate range, which is currently 5.25% to 5.50%*.
Those three 25-basis point cuts would have the US ending 2024 with Fed Fund rates between 4.5% and 4.75%.
In the other corner is the market, which doesn’t believe the Fed (ironically, about the Fed’s own behavior). CME’s FedWatch tool imputes rate expectations from the Fed Fund futures market, and the largest histogram bar expects Fed Fund rates of 3.75% to 4% as of the Fed’s 12/18/2024 meeting.
The market is expecting roughly double the cutting the Fed expects. And Wall Street banks have their own expectations, with UBS currently the most dovish with 275 basis points of expected cuts.
Interest Rate Questions:
Who is right?
How do interest rates affect the stock market?
What, if anything, should you do?
*For those new to Fed mechanics, the Fed Funds rate is the rate that banks that participate in the Federal Reserve system (which includes all nationally chartered banks and some state banks if they meet the requirements and choose to join; roughly ⅓ of US banks are part of the system, although this minority likely controls the lion’s share of deposits) charge *each other* on overnight loans to meet minimum reserve requirements. The Fed, unlike many other central banks, technically doesn’t set its baseline rate – it just encourages banks to do so. Since the Fed began paying interest on deposits, this has become easier, because would-be lenders will request at least the Fed’s deposit rate from would-be borrowers.
Interest Rate Answers:
Economics is a social science, and when you see many smart, well-informed people with widely varying views on a topic, it’s a sign that nobody really knows, at least conclusively.
Let’s unpack and as we do, (3) may be answered implicitly.
Higher interest rates slow down an economy by raising the cost of borrowing, and lower interest rates accelerate it by making loans more affordable. Central banks largely focus on this.
Mathematically, higher interest rates lower the values of companies by lowering the present value of future profits. In a discounted cash flow model, each expected future profit is divided by the quantity (1 + discount rate)number of years into the future.
If you project a very simple company to earn a single $100 cash flow in 10 years, and assume a 10% discount rate, that company is worth $38.55 now.
If you lower the discount rate to 6%, it’s worth $56.45.
This is “real economy” math.
If the real economy is a hot dog – just the meat part of the hot dog – the stock market would be that plus a “bun” of perception and anticipation.
The meat matters. For instance, central banks cut rates and kept them low following the 2008-2009 Great Financial Crisis, and stock markets (especially America’s) largely performed well during that low-rate period. As expected, biotechs and early-stage growth companies whose main projected cash flows are far into the future (and thus punished the most by high rates) did very well for 13+ years, and got clobbered in 2022 as the Fed raised rates 11 times.
Fed Researcher: 1 bps Treasury rate increase = 3.5 bps stock market drop
And there is research (some thinly cited; this one has just a single citation) to support rising rates being bad for equities: Chris Cotton from the Federal Reserve Bank of Boston found that every 1 basis point increase in the five-year Treasury rate lowers stock prices by about 3.5 basis points.
So if five-year rates rose from, say, 4% to 5%, stock prices would fall by 3.5%.
However, the bun matters, too.
Much of the empirical evidence – albeit more granular in many cases – on stocks and interest rates shows the opposite.
BlackRock: Sorry, but stocks rise after rate hikes
BlackRock found that since 1995, the S&P 500 rose by 3.2% in the three months following 50-basis point rate hikes.
That’s counterintuitive.
Speaking of counterintuitive and speaking of BlackRock, this article by Russ Koesterich has the following graphic, which shows inflation adjusted 10-year yields versus S&P 500 P/E ratios from 1997 to 2020.
The regression line shows that higher interest rates map to higher P/E ratios. P/E is a fraction, so P/Es can rise because investors are paying more for the same earnings, or they can rise because earnings dropped and patient investors kept the faith by not lowering the stock price.
Some research has shown that the “rising rates hurt stocks” story is a numerator story (i.e., rates affect company financials) as well as a denominator story (i.e., different discount rates), and numerator effects may explain a chunk of this. But, still, it’s unexpected.
Want more? Here’s a table from Ben Carlson, updating one originally published by Jack Bogle (as found in this Investing.com article by Lance Roberts):
Sam Ro, who publishes Tker.co, recently shared some data from BMO Investment Strategy Group. One point was that from 1979-2022, during rate-hike cycles, the S&P 500 has risen 10.7% annually, on average.
Why can’t anyone provide a definitive answer on stocks and interest rates?
If you came to this article looking for clear, exact, specific guidance on how stocks behave as interest rates move, my apologies. In fact, the whole point is that there is no clear, exact, specific guidance on this topic.
In a data sense, we haven’t had all that many rate hike periods in the modern US economy, first of all, and each one is a little different. And a pet theory I’m nursing is that because the stock market is anticipatory, the “bad news” of rate hikes tends to hit stocks in advance of the actual rate hikes – and during at least the tail end of rate-hike periods, investors are similarly looking ahead to rate-drop periods and pricing those in. Just conjecture – it’s likely that this has been studied somewhere.
Some good news for investors: Per Yahoo! Finance, rate hike peaks in 1995, 2006, and 2018 were each followed by a year of 20%+ gains.
For a muted version of this, let’s re-channel Sam Ro, who himself channeled BMO Investment Strategy’s graphic showing that since 1979, when rates have been above their three-year average and then start falling, the S&P’s average return in the following year is 10.4%.
Either 20% or 10.4% would be a decent return – especially after a year in which the S&P 500 returned 26%.
So what do rising – or falling – interest rates mean for investors?
Given enough data, whatever you want them to.
