When the US Federal Reserve (the Fed) raises interest rates, borrowing becomes more expensive across the world's largest economy, and the effects spread to shares, bonds, the dollar and markets such as India. This article explains why the Fed raises rates, what usually follows, which companies feel it most and least, and why the market's reaction is never the same twice.
Why the Fed raises rates
The Fed's Federal Open Market Committee (FOMC) sets a target range for the federal funds rate, the overnight rate at which US banks lend to each other. Its goals are stable prices and maximum employment. The Fed usually raises rates when inflation is too high: making money more expensive slows borrowing and spending, which in time reduces the pressure on prices.
This is the key difference from a rate cut. Cuts often come when inflation is cooling or the economy needs support; hikes come when the economy or prices are running too hot. The reason behind the move shapes how markets react.
What usually happens when the Fed raises rates
Borrowing costs rise. Companies with floating-rate loans pay more interest straight away, and new borrowing costs more. Credit cards, car loans and business loans become more expensive for consumers too, which can slow spending.
Safe savings pay more. Money-market funds, deposits and short-term government bonds offer higher returns, so some investors move money out of shares and into these safer options.
Valuations come under pressure. A share's price reflects expected future profits. Higher interest rates make those future profits worth less in today's money, which can push prices down even if profits do not change. Fast-growing companies whose profits are expected far in the future are usually hit hardest.
The dollar tends to strengthen. Higher US rates make dollar deposits and bonds more attractive, drawing money towards the dollar and away from other currencies.
Who feels it most, and who can cope
Heavy borrowers such as utilities, real estate companies and telecom operators carry large debts, so higher rates raise their interest bills and can squeeze profits, especially as old loans are refinanced at new rates.
Banks can sometimes benefit at first, because the interest they earn on loans may rise faster than what they pay on deposits. Over time, though, higher rates can slow lending and increase bad loans.
Companies with net cash (more cash than debt) are in the opposite position: they pay little interest and earn more on the cash they hold. Higher rates still affect their valuations and demand, but not their own borrowing costs.
Example on PositoAI: borrowers vs cash holders, United States
In their latest yearly results, property company Realty Income paid about $19.2 in interest per $100 of sales and power company NextEra Energy about $16.7, with net debt of about 55% and 57% of their market values. Microsoft paid about $0.9 and held slightly more cash than debt. A rise in rates means higher costs for the first two and more interest income on cash for the third. (Latest yearly results, as on 20 Oct 2026.)
Why the reaction varies
Markets look ahead, so an expected hike is often already reflected in prices before it happens. What moves markets more is a surprise, or a change in what the Fed signals about future hikes. A hike that comes with signs that inflation is under control can even be followed by rising share prices, while a hike that hints at many more to come can push prices down.
Long-term bond yields do not always rise with the Fed's rate either; they depend on what investors expect for inflation and growth over many years.
A recent example: 2022–2023
After inflation surged, the Fed raised its target range from near zero in March 2022 to 5.25–5.50% by mid-2023, one of the fastest series of increases in decades. During that period, many share prices fell, especially those of fast-growing technology companies, bond prices dropped sharply as yields rose, and the dollar strengthened against most currencies. The episode is a clear illustration of the forces described above, though no two cycles play out the same way.
Why it matters for India
Higher US rates can draw foreign investors' money back to the US, where they can now earn more with less risk. When foreign investors sell Indian shares and bonds, the rupee can weaken and Indian markets can come under pressure. A weaker rupee tends to hurt importers and companies with dollar loans, and to help exporters such as IT services companies, whose dollar earnings convert into more rupees.
Example on PositoAI: an Indian view
On 20 Oct 2026, PositoAI converted US-dollar prices at about ₹94.8 per dollar. Infosys, whose yearly results on PositoAI are reported in US dollars, is an example of an exporter whose revenue rises in rupee terms when the rupee weakens. On the other side, Indian companies with net cash, such as Maruti Suzuki (net cash about 5% of its market value) and TCS (about 3%), carry little exposure to higher borrowing costs. (Latest yearly results, as on 20 Oct 2026.)
Common misconceptions
"Rate hikes always make the market fall." Expected hikes may already be priced in, and a hike that shows inflation is under control can calm markets.
"Higher rates hurt every company." Companies with net cash earn more on their cash, and some banks can benefit at first.
"The Fed only affects America." Its decisions shift global money flows, the dollar and markets such as India.
Frequently asked questions
Why does the Fed raise rates?
Mainly to bring down inflation by making borrowing and spending more expensive.
Which sectors are most affected by hikes?
Usually heavy borrowers such as utilities, real estate and telecom, and fast-growing companies whose value depends on distant profits.
How do Fed hikes affect India?
They can pull foreign money out of Indian markets and weaken the rupee, which affects importers and exporters differently.
Do bond prices fall when the Fed raises rates?
Usually, yes: existing bonds with lower fixed coupons become less attractive, so their prices fall.

Summary
The Fed raises its federal funds target mainly to cool inflation. Higher rates usually raise borrowing costs, make safe savings more attractive, pressure share valuations and strengthen the dollar. Heavy borrowers feel it most, while companies with net cash can even earn more. Expected hikes are often priced in, so surprises and signals about future moves matter more. In India, Fed hikes can pull foreign money out and weaken the rupee, which helps exporters and hurts importers.
