Interest rates affect the stock market through three channels: company profits, the value investors place on future earnings, and the competition stocks face from bonds and cash. When rates rise, borrowing costs more for companies and households, the present value of future profits shrinks, and safer assets pay more. Each of those pushes stock prices down, so equities often fall when the Federal Reserve hikes rates. When rates fall, the same forces work in reverse and tend to support stocks. The relationship is a tendency, not a rule. Markets usually react to how a rate decision compares with what investors expected, and the reaction depends on why rates are moving and what stage the economy is in.

The rate that starts the chain

The rate behind most market reactions in the U.S. is the federal funds rate, the rate banks, savings and loans, and credit unions charge each other for overnight loans of reserves. The Federal Open Market Committee (FOMC) sets a target range for it at its scheduled meetings, held eight times a year, and can act between meetings if conditions require.

The federal funds rate feeds into the rest of the economy. The prime rate, which banks charge their most creditworthy customers, is closely tied to it and anchors many credit card APRs, home equity lines and business loans. Longer-term rates such as 30-year mortgages are not set by the Fed but respond to its policy path and to inflation expectations.

The Fed raises rates to cool inflation and lowers them to support a slowing economy. Higher rates make money more expensive to borrow, which slows spending and credit growth, and cuts do the opposite. Other central banks, such as the European Central Bank and the Bank of England, follow the same basic logic with their own policy rates, though their mandates and tools differ.

Why higher rates tend to push stock prices down

A stock’s price reflects what investors expect a company to earn in the future and how much they are willing to pay today for those earnings. Rising rates hit both parts of that calculation.

Lower expected earnings

When the Fed raises its target, banks pay more to borrow and pass that cost on. Variable-rate debt such as credit cards, adjustable-rate mortgages and many business loans reprices upward. Households still have to pay their bills, so higher interest payments leave less disposable income for everything else. That lower spending shows up as weaker revenue for retailers, travel companies, carmakers and other businesses that depend on discretionary purchases.

Companies face a second hit on their own balance sheets. Firms that borrow to fund operations, acquisitions or expansion pay more on new debt and on floating-rate debt as it resets. Some projects that made sense at a lower cost of capital no longer clear the bar, so they are delayed or dropped. Higher interest expense and slower revenue growth together reduce expected profits, and lower expected profits mean lower stock prices.

A higher discount rate on future profits

Even if a company’s earnings forecast did not change, higher rates would reduce what those earnings are worth today. Investors value a future cash flow by discounting it:

Present value = Future cash flow ÷ (1 + r)^t

where r is the required annual return and t is the number of years until the cash arrives. The required return starts from the risk-free rate, usually a Treasury yield, and adds a premium for the extra risk of owning stocks. When Treasury yields rise, r rises with them.

Hypothetical example. Take $100 of profit a company expects to earn.

The same two-point increase barely touches the near-term cash flow but cuts the value of the distant one by about a sixth, which is why rate changes move some stocks far more than others.

The Gordon growth model shows the effect for a whole share: Price = Next year’s dividend ÷ (r − g), where g is the expected long-run dividend growth rate. With a hypothetical $2 dividend, 4% growth and an 8% required return, the price is $2 ÷ 0.04 = $50. Raise the required return to 9% and it becomes $2 ÷ 0.05 = $40, a 20% drop. Real stocks do not follow the model so neatly, but a higher required return lowers the price investors will pay for a given stream of income.

Competition from bonds and cash

Higher rates also change the alternatives. When Treasury bills, newly issued bonds, money market funds and certificates of deposit pay more, investors can earn a respectable return without taking equity risk. The extra return stocks offer over the risk-free rate, the equity risk premium, narrows if stock prices stay the same. Investors who feel they are no longer being paid enough for that risk move money into fixed income, and stock prices adjust down until the premium looks adequate again.

One rough comparison uses the earnings yield, the inverse of the price-to-earnings ratio. A market trading at a hypothetical 20 times earnings has an earnings yield of 5%. If a risk-free Treasury yields 2%, stocks look attractive by comparison. If the same Treasury yields 5%, the gap disappears, and stocks need either lower prices or faster earnings growth to compete.

Why the market reacts before the economy does

Rate changes work through the economy slowly. It usually takes 12 months or more for a change in policy to have a broad effect on spending, hiring and inflation. Stock prices, by contrast, often move within minutes of an FOMC statement. The difference comes from expectations.

Investors do not wait for a hike to adjust. They watch inflation data, employment reports, Fed officials’ speeches and the FOMC’s projections, including the dot plot of where each official expects rates to go. Futures tied to the federal funds rate translate those views into implied probabilities for each meeting, so by the time the decision is announced, the expected outcome is usually already in prices.

That is why the size of a move matters less than the size of the surprise:

• A hike that matches expectations often produces little lasting reaction, because it was priced in. Stocks can even rise if the accompanying statement suggests the Fed is close to finished.
• A larger or earlier hike than expected usually pushes stocks down, since investors have to reprice for higher borrowing costs and a tougher economy.
• A smaller cut than expected can send stocks lower even though rates are falling. If the market had priced in a 50 basis point cut and the Fed delivers 25, investors are left with higher rates than they planned for.
• A larger cut than expected often lifts stocks, as happened in September 2024 when the Fed cut by 50 basis points while many investors had expected 25.

Guidance can matter as much as the rate itself. A 25 basis point hike paired with language suggesting more hikes ahead can hit stocks harder than a larger hike that the Fed signals is the last. Sharp swings up and down on a decision day often reflect investors digesting the rate, the statement and the chair’s press conference in sequence.

Not every stock reacts the same way

Rate changes reprice sectors differently, which matters more to most investors than the direction of the overall index.

Growth stocks. Companies valued on profits expected many years out, common in technology and early-stage businesses, carry most of their value in distant cash flows. As the discounting example shows, those are the cash flows a higher rate hits hardest. Many growth companies also depend on outside capital to fund expansion, and that capital costs more when rates rise. Long periods of very low rates have historically favored these stocks, and rising rates tend to compress their valuations. The 2022 tightening cycle illustrates this: the Fed raised rates from near zero starting in March 2022, the S&P 500 lost close to a fifth of its value that year, and the technology-heavy Nasdaq Composite fell considerably more.

Financials. Banks, brokerages and insurers can benefit from higher rates. Banks earn the spread between what they charge borrowers and what they pay depositors, and that net interest margin often widens when rates rise, especially if deposit rates lag. Insurers and brokerages earn more on the cash and bonds they hold. The benefit has limits. Banks holding long-dated bonds bought at low yields face losses on those securities as rates climb, and rising deposit costs and loan defaults can erode the gains. The failure of Silicon Valley Bank in March 2023 followed losses on long-term securities after rapid rate increases.

Dividend payers and rate-sensitive income sectors. Utilities and real estate investment trusts (REITs) are often bought for income, which puts them in direct competition with bonds. They also tend to carry substantial debt. Both factors make them sensitive to rate changes: they often lag when rates rise and benefit when rates fall.

Defensive sectors. Consumer staples, household essentials and health care sell products people buy regardless of the economy. When the Fed raises rates to cool an overheating economy, demand for these companies tends to hold up better than demand for discretionary goods, which can make them relatively more resilient during tightening.

Highly indebted and cyclical companies. Firms with heavy floating-rate debt or businesses tied to big-ticket borrowing, such as homebuilders and automakers, feel higher rates in both their costs and their customers’ ability to buy.

What falling rates do to stocks

The Fed cuts rates when the economy is slowing or inflation is under control. Lower rates reverse the chain: borrowing gets cheaper for households and companies, debt service eats less of household budgets, and future profits are discounted at a lower rate. Bonds and cash pay less, so investors seeking returns tend to move toward equities.

The usual beneficiaries are companies with large borrowing needs, growth stocks with distant earnings, and income sectors such as utilities and REITs. Large companies with strong balance sheets can refinance debt at lower cost.

Low rates do not guarantee rising stocks. If the Fed is cutting because a recession is starting, the drop in earnings can outweigh the benefit of cheaper money, and stocks can keep falling while rates are being cut. Prolonged periods of very low rates also raise concerns about asset bubbles and excessive risk-taking, since cheap borrowing makes speculative bets easier to fund.

How bonds respond to rate changes

Bond prices and interest rates move in opposite directions. A bond pays a fixed coupon. When rates rise, new bonds pay higher coupons, so existing bonds with lower coupons are worth less and their prices fall until their yields match the market. When rates fall, existing higher-coupon bonds become more valuable and their prices rise.

The sensitivity of a bond’s price to rate changes is measured by duration. A rough rule: price change ≈ −duration × change in yield. A bond with a duration of 8 would lose about 8% of its value if yields rose by one percentage point, while a bond with a duration of 2 would lose about 2%. Longer maturities and lower coupons mean higher duration, so long-term bonds swing the most.

Rate changes also alter what borrowers pay. Governments and companies issuing new debt pay more when rates rise. When rates fall, issuers of callable bonds may redeem existing debt early and refinance, leaving investors reinvesting at lower yields, and savers in Treasury bills, CDs and annuities earn less.

When the usual pattern breaks

The rule of thumb that higher rates hurt stocks and lower rates help them holds only when other things are roughly equal. Several factors can override it.

The reason rates are moving. A Fed raising rates late in an expansion is often responding to strong demand and rising profits. In that environment, earnings growth can outpace the higher discount rate, and stocks can keep climbing for a time. Technology, growth and leisure companies have at times continued to do well in the early stages of such cycles. Conversely, cuts made in response to a crisis signal economic trouble.

Real versus nominal rates. What matters for valuations is the interest rate after inflation. If inflation rises faster than nominal rates, real rates fall, which can support asset prices even while the Fed is hiking.

Other forces. Earnings reports, inflation surprises, geopolitical events, fiscal policy and changes in investor sentiment all move stocks, sometimes more than rates do in a given period.

The 2008 financial crisis shows how loosely rates and crashes can be linked. The Fed raised its target from 1% in 2004 to 5.25% by mid-2006, which helped cool the housing boom. It then began cutting in September 2007 and brought rates down to a range of 0% to 0.25% by December 2008. The worst of the stock market decline came while rates were being cut, because the cuts were responding to a collapsing financial system rather than causing a recovery.

Negative interest rates

Negative policy rates are rare and have never been used by the Fed. The European Central Bank moved its deposit rate below zero in 2014 and the Bank of Japan adopted a negative rate in 2016. Under negative rates, banks pay to park reserves at the central bank, which is meant to push them to lend.

For stocks, negative rates cut both ways. They make bonds and cash unattractive, which can push investors into equities and lift valuations. They also signal serious concern about growth and deflation, and they squeeze bank profits by compressing lending margins. Markets in that environment can be volatile even as valuations rise.

Positioning when rates are rising

No single investment suits every rate environment, since each tightening cycle has its own causes. Some approaches are commonly considered when rates are going up:

1. Shorter-term bonds. Their lower duration means smaller price drops, and they mature sooner, allowing reinvestment at higher yields instead of locking in a long-term rate.
2. Inflation-protected bonds. If rates are rising because of inflation, Treasury Inflation-Protected Securities (TIPS) adjust their principal with the consumer price index.
3. Sector tilts. Financials and defensive sectors have tended to hold up better than growth stocks and heavily indebted companies.
4. Cash and short-term instruments. Money market funds and Treasury bills pay more as the Fed raises rates.

Some investors short the market or buy inverse funds if they expect rate hikes to hurt equities, which carries the risk of loss if stocks rise instead. A diversified portfolio spread across asset classes reduces dependence on getting the rate call right.

The Bottom Line

Interest rates matter to anyone holding stocks or bonds, because they shape company profits, the value of future earnings and the appeal of safer assets. Higher rates tend to weigh on stocks, especially growth names and rate-sensitive income sectors, while falling rates usually help. The pattern can break when a recession or strong earnings drive markets, so a portfolio spread across asset classes reduces dependence on predicting the Fed correctly.
