The federal funds rate is the interest rate at which depository institutions trade federal funds (balances held at Federal Reserve Banks) with each other overnight. When a depository institution has surplus balances in its reserve account, it lends to other banks in need of larger balances. In simpler terms, a bank with excess cash, which is often referred to as liquidity, will lend to another bank that needs to quickly raise liquidity. (1) The rate that the borrowing institution pays to the lending institution is determined between the two banks; the weighted average rate for all of these types of negotiations is called the effective federal funds rate.(2) The effective federal funds rate is essentially determined by the market but is influenced by the Federal Reserve as it uses the Interest on Reserve Balances rate to steer the federal funds rate toward the target range.(2)

The Federal Open Market Committee (FOMC) meets eight times a year to determine the federal funds target range. The Fed's primary tool for influencing the federal funds rate is the interest the Fed pays on the funds that banks hold as reserve balances at their Federal Reserve Bank, which is the Interest on Reserves Balances (IORB) rate. Because banks are unlikely to lend funds in the federal funds market for less than they get paid in their reserve balance account at the Federal Reserve, the Interest on Reserve Balances (IORB) is an effective tool for guiding the federal funds rate. (3) Whether the Federal Reserve raises or lowers the target range for the federal funds rate depends on the state of the economy. If the FOMC believes the economy is growing too fast and inflation pressures are inconsistent with the dual mandate of the Federal Reserve, the Committee may temper economic activity by raising the target range for federal funds rate, and increasing the IORB rate to steer the federal funds rate into the target range. In the opposing scenario, the FOMC may spur greater economic activity by lowering the target range for federal funds rate, and decreasing the IORB rate to steer the federal funds rate into the target range. (3) Therefore, the FOMC must observe the current state of the economy to determine the best course of monetary policy that will maximize economic growth while adhering to the dual mandate set forth by Congress. In making its monetary policy decisions, the FOMC considers a wealth of economic data, such as: trends in prices and wages, employment, consumer spending and income, business investments, and foreign exchange markets.

The federal funds rate is the central interest rate in the U.S. financial market. It influences other interest rates such as the prime rate, which is the rate banks charge their customers with higher credit ratings. Additionally, the federal funds rate indirectly influences longer- term interest rates such as mortgages, loans, and savings, all of which are very important to consumer wealth and confidence.(2)

The Personal Consumption Expenditures Price Index is a measure of the prices that people living in the United States, or those buying on their behalf, pay for goods and services. The change in the PCE price index is known for capturing inflation (or deflation) across a wide range of consumer expenses and reflecting changes in consumer behavior. For example, if car prices rise, car sales may decline while bicycle sales increase.

The PCE Price Index is produced by the Bureau of Economic Analysis (BEA), which revises previously published PCE data to reflect updated information or new methodology, providing consistency across decades of data that's valuable for researchers. They also offer the series as a Chain-Type index and excluding food and energy products, as above. The PCE price index less food excluding food and energy is used primarily for macroeconomic analysis and forecasting future values of the PCE price index.

The PCE Price Index is similar to the Bureau of Labor Statistics' consumer price index for urban consumers. The two indexes, which have their own purposes and uses, are constructed differently, resulting in different inflation rates.
