Quick answer: The Federal Reserve (the Fed), the central bank of the United States, controls inflation mainly by influencing interest rates. When inflation runs above its 2% target, the Fed raises its key policy rate, the federal funds rate, which makes borrowing more expensive, slows spending and investment, cools demand and gradually brings price rises down. It also uses other tools: paying interest on banks' reserves, buying or selling bonds (quantitative easing and tightening), lending through the discount window, and "forward guidance" about future policy. Because the US dollar is the world's main reserve currency, Fed decisions also affect markets, currencies and interest rates in countries like India.
Inflation affects everyone. When prices rise faster than incomes, groceries, rent, fuel and school fees take a bigger share of the budget, and savings lose value. The job of keeping inflation in check falls largely to central banks, and the most closely watched of them is the US Federal Reserve.
This article explains what the Fed is, why it targets inflation, the tools it uses, how interest rate changes travel through the economy, key moments in its history, the challenges it faces, and why its decisions matter far beyond America.

What Is the Federal Reserve?
The Federal Reserve System was created by the Federal Reserve Act, signed in December 1913, after a series of banking panics, especially the Panic of 1907, showed the need for a central authority to stabilise the financial system.
The Fed has three main parts:
- The Board of Governors in Washington, D.C.: seven members nominated by the President and confirmed by the Senate, for staggered 14-year terms. The Chair serves a four-year term as chair.
- Twelve regional Federal Reserve Banks, in cities including New York, Chicago and San Francisco.
- The Federal Open Market Committee (FOMC), which sets monetary policy.
The Fed is designed to be independent in its day-to-day policy decisions, so that interest rates are set based on economic conditions rather than short-term political pressure, although it remains accountable to Congress.
The Fed's Mandate: Stable Prices and Maximum Employment
Congress has given the Fed goals often described as the "dual mandate": maximum employment and stable prices. (The law also mentions moderate long-term interest rates.)
Since January 2012, the Fed has formally defined price stability as inflation of 2% a year, measured by the personal consumption expenditures (PCE) price index. Why not zero? A small positive rate gives a buffer against deflation, a damaging fall in prices, and leaves room to cut interest rates in downturns. Many other central banks use similar targets; the Reserve Bank of India's target, for example, is 4% consumer price inflation with a tolerance band of 2% to 6%.
The two goals sometimes conflict. Raising rates to fight inflation can slow the economy and increase unemployment; keeping rates low to support jobs can let inflation rise. Balancing them is the central challenge of monetary policy.
Why Inflation Matters
- It erodes purchasing power. At 3% inflation, $100,000 buys only about $74,400 worth of today's goods after 10 years. At 6%, it falls to about $55,800.
- It hurts people on fixed incomes, such as retirees and savers.
- It creates uncertainty, making it harder for businesses to plan.
- High inflation can become self-reinforcing if people expect prices to keep rising and demand higher wages and prices in response.
Deflation is also harmful, encouraging people to delay purchases and increasing the real burden of debt. That's why the Fed aims for low, stable, positive inflation.
How the Fed Measures Inflation
Inflation can be measured in several ways, and the Fed watches all of them:
- Consumer Price Index (CPI): published monthly by the Bureau of Labor Statistics, it tracks prices of a basket of goods and services bought by urban consumers. It's the figure most often quoted in the news.
- Personal Consumption Expenditures (PCE) price index: published by the Bureau of Economic Analysis, it covers a broader range of spending and adjusts more readily as people switch between products. This is the Fed's preferred measure, and it usually runs a little below CPI.
- Core inflation: both CPI and PCE have "core" versions that exclude volatile food and energy prices. Core inflation helps the Fed see the underlying trend rather than temporary swings.
- Inflation expectations: surveys of households and businesses, and market measures derived from bond prices, show what people expect inflation to be. The Fed watches these closely because expectations can shape future wage and price decisions.
- Wage growth: rapid wage increases without matching productivity gains can feed into prices, especially in services.
The Phillips Curve: Inflation Versus Unemployment
In 1958, economist A. W. Phillips published research showing that, historically in the UK, periods of low unemployment tended to coincide with faster wage growth. Others extended this into the "Phillips curve": a trade-off between inflation and unemployment.
The idea seemed to suggest that policymakers could choose a bit more inflation in exchange for lower unemployment. But in the 1970s, the US experienced "stagflation": high inflation and high unemployment at the same time. Economists including Milton Friedman and Edmund Phelps had argued that the trade-off only holds in the short run, because people adjust their expectations. If the central bank tries to keep unemployment below its sustainable level, inflation just keeps accelerating.
Today, most economists see the Phillips curve as a loose, shifting relationship. In the decade before the pandemic, unemployment fell to low levels without much inflation, leading some to describe the curve as "flat". The post-pandemic surge showed that inflation can still respond strongly when demand overwhelms supply. For the Fed, the lesson is that the labour market matters for inflation, but the relationship is unpredictable.
Rules of Thumb: The Taylor Rule
In 1993, economist John Taylor proposed a simple formula describing how a central bank might set interest rates. A common version is:
Policy rate = inflation + 0.5 × output gap + 0.5 × (inflation − 2) + 2
The output gap measures how far the economy is above or below its sustainable level, as a percentage. Some examples:
- Inflation at 2%, output gap of zero: the rule suggests a rate of 4%.
- Inflation at 4%, output gap of zero: the rule suggests 7%.
- Inflation at 6%, economy running 1% above potential: the rule suggests 10.5%.
- Inflation at 3%, economy 2% below potential: the rule suggests 4.5%.
The Fed doesn't follow the Taylor rule mechanically, and different versions give different answers. But economists and investors use it as a benchmark to judge whether policy looks too tight or too loose. In 2021 and early 2022, many versions of the rule suggested rates far higher than the near-zero level the Fed was holding, which critics later cited as evidence that the Fed had acted too late.
The Fed's Main Tools
1. The Federal Funds Rate
This is the interest rate banks charge each other for overnight loans of reserves. The FOMC sets a target range for it, such as 5.25% to 5.50%. It's the Fed's primary policy tool, and changes ripple out to rates on loans, mortgages, credit cards and savings accounts.
2. Interest on Reserve Balances (IORB)
The Fed pays interest on the reserves banks hold with it. Because banks won't lend to each other for much less than they can earn safely at the Fed, adjusting this rate helps keep the federal funds rate within its target range. An overnight reverse repurchase (ON RRP) facility performs a similar role for a wider group of institutions, such as money market funds.
3. Open Market Operations
The Fed buys and sells government securities. Buying adds money to the banking system; selling, or letting securities mature without replacing them, removes it.
4. Quantitative Easing and Tightening
When short-term rates are already near zero, the Fed can buy large amounts of longer-term bonds, known as quantitative easing (QE), to push down long-term interest rates. It did this after the 2008 financial crisis and during the COVID-19 pandemic, when its balance sheet grew to roughly $9 trillion. Quantitative tightening (QT) reverses the process, shrinking the balance sheet and putting upward pressure on long-term rates.
5. The Discount Window
Banks can borrow directly from the Fed, usually as a backstop source of liquidity. The rate charged is called the discount rate or primary credit rate.
6. Forward Guidance
By signalling its likely future policy, the Fed influences expectations and long-term interest rates even before it acts. After each FOMC meeting, it publishes a statement, and four times a year it releases projections, including the "dot plot" showing where each official expects rates to go.
7. Reserve Requirements
Historically, the Fed required banks to hold a percentage of deposits as reserves. It reduced this requirement to zero in March 2020, so it's no longer an active tool.
How Interest Rate Hikes Bring Inflation Down
When the Fed raises rates, the effects spread through several channels, a process economists call the "monetary transmission mechanism":
- Borrowing costs rise. Mortgages, car loans, business loans and credit cards become more expensive. For example, the monthly payment on a $300,000, 30-year mortgage is about $1,265 at 3% but about $1,996 at 7%.
- Spending and investment slow. Households buy fewer big-ticket items; businesses delay expansion.
- Saving becomes more attractive as deposit rates rise.
- Asset prices may fall, as higher rates reduce the present value of future earnings, making people feel less wealthy.
- The dollar tends to strengthen, making imports cheaper.
- Demand cools, so businesses find it harder to raise prices and the labour market loosens.
- Expectations stabilise, as people trust that inflation will return to target.
Economist Milton Friedman famously described monetary policy as acting with "long and variable lags". The full effect of a rate change can take a year or more, so the Fed has to act on forecasts, not just current data.
The FOMC: Who Decides?
The FOMC has 12 voting members: the seven governors, the president of the Federal Reserve Bank of New York, and four of the other 11 regional bank presidents, who serve one-year rotating terms. It meets eight times a year, and can meet in between if needed. Decisions are announced at 2 p.m. Eastern Time, followed by a press conference by the Chair.
Historical Lessons
The Great Inflation and Paul Volcker
In the 1970s, oil shocks and loose policy pushed US inflation into double digits; consumer price inflation peaked at about 14.8% in early 1980. Fed Chair Paul Volcker, appointed in 1979, raised the federal funds rate dramatically, to around 20% at its peak in 1981. The result was a painful recession and high unemployment, but inflation fell sharply. The episode established the importance of central bank credibility.
The 2008 Financial Crisis
The Fed cut rates to near zero and launched QE to prevent a collapse of the financial system and support recovery.
The Post-Pandemic Inflation Surge
After the pandemic, supply-chain disruptions, strong demand, government support and energy price shocks pushed US consumer price inflation to about 9.1% in June 2022, the highest in about four decades. The Fed, which had initially described the inflation as likely "transitory", began raising rates in March 2022 and raised its target range from near zero to 5.25%–5.50% by July 2023, one of the fastest tightening cycles in decades. Inflation fell substantially without a recession occurring at the time, and the Fed began cutting rates in September 2024.
Challenges in Controlling Inflation
- Supply shocks, such as oil price spikes or crop failures, raise prices in ways interest rates can't directly fix.
- Time lags make it easy to tighten or loosen too much.
- Data uncertainty: economic data is often revised.
- Financial stability risks: rapid rate hikes can stress banks, as seen with the failure of Silicon Valley Bank in March 2023.
- Government debt: higher rates increase the cost of servicing public debt.
- Political pressure on central bank independence.
Inflation Control and Financial Stability
The Fed also plays a central role in keeping the financial system stable, and this sometimes interacts with its fight against inflation.
- Lender of last resort: in a panic, the Fed can lend to sound banks that face sudden withdrawals, preventing a liquidity crisis from becoming a solvency crisis.
- Bank supervision: the Fed supervises many large banks and runs annual "stress tests" to check whether they could survive a severe downturn.
- Balancing goals: in March 2023, after Silicon Valley Bank and Signature Bank failed, partly because the value of their bond holdings fell as rates rose, the Fed created an emergency lending facility for banks while still continuing to raise rates to fight inflation. This showed that it can use separate tools for separate problems: lending facilities for financial stability, interest rates for inflation.
Very low interest rates kept for long periods can encourage excessive borrowing and risk-taking, and asset bubbles. Rapid increases can expose weak spots in the financial system. Central banks therefore watch financial conditions closely as part of their policy decisions.
Changes to the Fed's Strategy
In 2020, the Fed adopted a framework called "flexible average inflation targeting", under which it would aim for inflation moderately above 2% for some time after periods of below-target inflation. The post-pandemic surge led to criticism that this approach made the Fed slow to respond. In 2025, the Fed completed a review of its framework and dropped the average-inflation approach, returning to a more conventional emphasis on 2% inflation. Frameworks evolve, so check the Fed's latest statements for its current approach.
How the Fed Compares With Other Central Banks
- European Central Bank (ECB): its primary mandate is price stability for the euro area, defined since 2021 as a symmetric 2% inflation target over the medium term. Unlike the Fed, it has no equal employment mandate.
- Bank of England: targets 2% CPI inflation, a target set by the UK government; its Monetary Policy Committee sets the Bank Rate.
- Reserve Bank of India (RBI): since 2016, India has used flexible inflation targeting, with a 4% CPI target and a 2% to 6% band. A six-member Monetary Policy Committee sets the repo rate. India's inflation is more influenced by food prices and monsoon conditions than US inflation.
- Bank of Japan: struggled for decades with low inflation or deflation and kept rates negative from 2016 until it raised them in March 2024.
All these banks use similar tools, mainly a short-term policy rate supported by liquidity operations and communication, but their mandates and challenges differ.
Why Fed Decisions Matter for India
Because the US dollar dominates global trade and finance, Fed policy spills over to other countries:
- Capital flows: when US rates rise, investors may pull money from emerging markets like India to earn higher, safer returns in the US. This can pressure Indian stocks and bonds.
- The rupee: outflows and a stronger dollar tend to weaken the rupee, making imports such as crude oil and electronics more expensive, which can feed Indian inflation.
- RBI policy: the RBI considers Fed moves when setting rates and managing the rupee, though its decisions are driven mainly by domestic conditions.
- Borrowing costs: Indian companies that borrow in dollars face higher costs when US rates rise and the rupee weakens.
- Students and families: a weaker rupee raises the cost of studying abroad and makes remittances from the US worth more in rupees.
The 2013 "taper tantrum", when the Fed signalled it would slow its bond purchases, is a well-known example: the rupee fell sharply over the following months and Indian markets were volatile.
What Fed Decisions Mean for Your Money
- Borrowers: when rates are rising, consider fixing rates where sensible and paying down high-interest variable debt.
- Savers: higher rates mean better returns on deposits and short-term bonds; shop around.
- Investors: rate changes can move stock and bond prices sharply. Avoid reacting to every headline; a diversified, long-term plan is usually wiser than trying to time Fed decisions.
- Anyone with foreign-currency costs: if you plan to pay for overseas education or travel, consider the currency risk and spread conversions over time.

Frequently Asked Questions: How Does the Fed Control Inflation
How does the Federal Reserve control inflation?
Mainly by raising or lowering the federal funds rate, supported by interest on reserves, bond purchases or sales, lending facilities and forward guidance.
What is the Fed's inflation target?
2% a year, measured by the PCE price index.
Why do Fed decisions affect India?
Higher US rates can draw investment money out of emerging markets, weaken the rupee and influence RBI decisions and Indian stock markets.
Why does the Fed raise interest rates when prices are already high?
Higher rates cool demand, which slows the pace of future price increases. They don't usually lower prices that have already risen; the aim is to bring inflation, the rate of increase, back to 2%.
Does the Fed print money?
The Fed creates bank reserves electronically when it buys assets, which is often described as "printing money". Physical currency is printed by the Treasury's Bureau of Engraving and Printing and issued through the Fed.
Who appoints the Fed Chair?
The US President nominates the Chair from among the governors, and the Senate confirms the appointment for a four-year term.
How often does the Fed change interest rates?
The FOMC meets eight times a year and may change rates at any meeting, or hold them steady. It can also act between meetings in emergencies, as it did in March 2020.
Can the Fed cause a recession?
Aggressive rate hikes can slow the economy enough to cause a recession, as happened in the early 1980s. The Fed tries to achieve a "soft landing", where inflation falls without a severe downturn.
Final Thoughts
The Federal Reserve's job is to keep inflation low and stable while supporting jobs, and its main lever is the cost of money. Understanding how it works helps explain moves in interest rates, markets and currencies around the world, and helps you make better decisions about borrowing, saving and investing.
