In summary
Federal funds are reserve balances that eligible financial institutions can lend to one another, typically overnight, in the US federal funds market. The federal funds rate is the interest rate on these transactions.
- Federal funds are held as reserve balances at Federal Reserve Banks.
- Banks can lend reserve balances to other eligible institutions that need short-term funding.
- The federal funds rate is an overnight interest rate in the US banking system.
- The FOMC sets a target range rather than setting every individual transaction rate.
- As of 17 September 2026, the target range is 3.75% to 4%.
- Changes in the federal funds rate can influence other short-term interest rates.
- Federal funds and the federal funds rate are related but are not the same thing.
The Bajaj Broking website provides investment-related information, while federal funds are primarily a US banking and monetary-policy concept.
What are federal funds?
Federal funds are reserve balances held by banks and other eligible depository institutions at Federal Reserve Banks. Institutions with available reserve balances can lend them to other eligible institutions that need overnight funding.
The term federal funds therefore refers to the reserve balances being lent, while the federal funds rate refers to the interest rate associated with borrowing those balances.
The Federal Reserve explains that the federal funds rate is the rate banks pay to borrow reserve balances overnight.
For example, suppose Bank A has more reserve balances than it needs for its immediate liquidity requirements, while Bank B needs additional overnight funding. Bank A can lend eligible reserve balances to Bank B, with the transaction carrying an interest rate.
Why do banks use federal funds?
Banks need liquidity to manage their daily payments, settlements, and other obligations. Reserve balances are one source of liquidity within the US banking system.
A bank with available reserve balances may lend them, while another institution may borrow when it needs additional overnight funding.
The federal funds market therefore helps institutions manage short-term liquidity.
However, the mechanics of the market have changed over time. Since the global financial crisis, the Federal Reserve has operated an ample-reserves framework, in which administered rates such as interest on reserve balances play an important role in keeping the federal funds rate within its target range.
What is the federal funds rate?
The federal funds rate is the interest rate at which banks and other eligible institutions borrow reserve balances overnight in the US federal funds market.
The Federal Open Market Committee (FOMC) sets a target range for the federal funds rate as part of US monetary policy. Individual transactions can occur at rates that differ within the market.
As of 17 September 2026, the FOMC's target range for the federal funds rate is 3.75% to 4%, following a 0.25 percentage-point increase.
This rate is different from the interest rate charged to an individual consumer on a loan or credit card. However, changes in the federal funds rate can influence other short-term interest rates and broader financial conditions.
How does the federal funds market work?
The basic process can be understood through a simple example.
Suppose Bank A has excess reserve balances, while Bank B needs additional overnight liquidity.
- Bank A has available reserves: It has reserve balances that it can lend.
- Bank B needs liquidity: It seeks short-term funding in the federal funds market.
- The institutions agree to a transaction: The eligible institutions agree on the amount and applicable interest rate.
- The funds are lent overnight: The transaction generally has a very short maturity, often overnight.
- The borrowing institution repays: Bank B repays the amount borrowed plus the applicable interest.
The federal funds market is therefore primarily a mechanism for managing very short-term liquidity between eligible financial institutions.
Who sets the federal funds rate?
The FOMC sets the target range for the federal funds rate.
The FOMC is the monetary-policy body within the Federal Reserve System. Its decisions are based on economic and financial conditions and are intended to support the Federal Reserve's statutory goals.
The FOMC does not set the interest rate on every individual federal funds transaction. Instead, it establishes a target range, while the Federal Reserve uses its monetary-policy tools to keep the market rate consistent with that range.
In September 2026, the FOMC raised the target range to 3.75%–4%.
Why is the federal funds rate important?
The federal funds rate is one of the most closely watched short-term interest rates in the US because changes can influence broader financial conditions.
When the target rate changes, other interest rates can also respond. The Federal Reserve notes that changes in the federal funds rate can affect rates on short-term loans, commercial paper, Treasury bills, and some floating-rate loans.
This can affect:
- Borrowing costs: Businesses and consumers may face changes in borrowing costs as market rates adjust.
- Spending and investment: Changes in financing costs can influence borrowing and spending decisions.
- Inflation: Higher interest rates can reduce demand by making borrowing more expensive, while lower rates can encourage borrowing and spending.
- Financial markets: Changes in interest rates can affect valuations and investor expectations.
- Exchange rates: Interest-rate changes can influence demand for currencies, although exchange rates depend on many factors.
The effect is not immediate or identical across every financial product.
What happens when the federal funds rate increases?
A higher federal funds rate generally increases the cost of short-term borrowing in the financial system.
For example, if the FOMC raises its target range, banks and other lenders may face higher funding costs. These changes can gradually affect other interest rates.
Higher borrowing costs can reduce demand for loans and spending. This can contribute to slower economic activity and may help reduce inflationary pressure.
However, the actual effect depends on economic conditions, financial-market expectations, and how quickly changes pass through to other rates.
What happens when the federal funds rate decreases?
A lower federal funds rate can reduce short-term borrowing costs and ease financial conditions.
Lower rates can make borrowing more attractive to businesses and households, potentially supporting spending and investment.
However, the effect depends on factors such as credit demand, lending standards, economic confidence, and conditions in financial markets.
A lower policy rate does not automatically mean that every loan, mortgage, or investment will become cheaper or more valuable.
What is the difference between federal funds and the federal funds rate?
The terms are closely related but refer to different things.
| Factor | Federal funds | Federal funds rate |
|---|---|---|
| Meaning | Reserve balances lent between eligible institutions | Interest rate associated with overnight federal funds transactions |
| Nature | Financial reserves | Interest rate |
| Main market | US federal funds market | US federal funds market |
| Policy role | Provides liquidity for eligible institutions | Key US monetary-policy rate |
| Set directly by FOMC? | No | FOMC sets the target range |

Understanding this distinction is important because the funds are the balances being borrowed and lent, while the rate is the price of borrowing them.
Are federal funds the same as the repo market?
No. The federal funds market and repo market are different parts of the short-term funding system.
Federal funds involve borrowing reserve balances, while a repurchase agreement, or repo, generally involves borrowing cash against securities as collateral.
This distinction matters because the Federal Reserve uses several tools and markets to implement monetary policy and manage financial conditions.
Are federal funds relevant to India?
Federal funds are specifically associated with the US financial system and Federal Reserve monetary policy.
India has its own monetary-policy framework, administered by the Reserve Bank of India (RBI). The RBI uses policy tools such as the repo rate to influence monetary and financial conditions in India.
Therefore, federal funds should not be described as an Indian equivalent of RBI policy operations. The US federal funds rate and India's repo rate are separate policy rates set by different central banks within different monetary-policy frameworks.
How can the federal funds rate affect investors?
Investors may track the federal funds rate because changes in US interest rates can affect financial conditions and asset prices.
For example, higher US interest rates can influence bond yields, borrowing costs, currency movements, and equity valuations. The direction and size of these effects can vary according to market expectations and wider economic conditions.
Investors should therefore treat the federal funds rate as one economic indicator, rather than assuming that a particular rate movement will automatically cause an investment to rise or fall.
For investors exploring mutual funds, the underlying portfolio, investment objective, risk level, costs, and time horizon remain important factors. The Bajaj Broking website provides information on mutual fund investments, including different fund categories. You can also learn about a fund of funds, where a mutual fund invests primarily in other funds.
What is the historical federal funds rate?
The federal funds rate has changed substantially over different economic cycles.
The source page notes that the federal funds rate reached 20% in 1980, during a period of severe inflationary pressure. It also reached a target range of 0% to 0.25% during the global financial crisis and again in 2020.
Historical rates should be viewed in their economic context. Comparing a rate from one period directly with today's rate without considering inflation, economic growth, financial conditions, and monetary-policy frameworks can be misleading.
Conclusion
Federal funds are reserve balances that eligible financial institutions can lend to one another, typically overnight, while the federal funds rate is the interest rate associated with these transactions.
The FOMC sets a target range for the federal funds rate as part of US monetary policy. Changes in this rate can influence borrowing costs, financial conditions, inflation, economic activity, and markets.
As of 17 September 2026, the target range is 3.75% to 4%. When interpreting changes in the rate, it is important to consider the wider economic and financial environment rather than viewing the rate in isolation.
