What is the most commonly used means of changing the money supply?
The most direct approach is to loan it to other banks. By loaning that money, banks increase the money supply and lowers the interest rate called the Fed Funds rate (the interest rate that banks charge each other for loans). The Fed Funds rate influences other interest rates in the economy, such as home loans.
Open market operations are used by the Federal Reserve to move the federal funds rate and influence other interest rates. It does this to stimulate or slow down the economy. The Fed can increase the money supply and lower the fed funds rate by purchasing, usually, Treasury securities.
The most commonly used tool of monetary policy in the U.S. is open market operations. Open market operations take place when the central bank sells or buys U.S. Treasury bonds in order to influence the quantity of bank reserves and the level of interest rates.
Conducting monetary policy
If the Fed, for example, buys or borrows Treasury bills from commercial banks, the central bank will add cash to the accounts, called reserves, that banks are required keep with it. That expands the money supply.
The major tool the Fed uses to affect the supply of reserves in the banking system is open market operations—that is, the Fed buys and sells government securities on the open market. These operations are conducted by the Federal Reserve Bank of New York.
Open Market Operations
OMO can increase or decrease the total supply of money and also affect interest rates. The Fed increases the money supply in the economy by swapping out bonds in exchange for cash to the general public when it buys bonds in the open market.
The Working Group recommended compilation of four monetary aggregates on the basis of the balance sheet of the banking sector in conformity with the norms of progressive liquidity: M0 (monetary base), M1 (narrow money), M2 and M3 (broad money) (see Box 10.1).
1. The most direct method the Fed uses to change the monetary base is open market operations, which is buying or selling U.S. government securities.
M1 and M2 money are the two mostly commonly used definitions of money. M1 = coins and currency in circulation + checkable (demand) deposit + traveler's checks + saving deposits. M2 = M1 + money market funds + certificates of deposit + other time deposits.
The money supply ( ) is a fixed amount that doesn't change just because interest rates have changed. The money supply changes when either the monetary base changes or banks make loans.
What changes the supply of a currency?
The supply of a currency changes based on how much people using that currency want the goods, services, or assets in other countries. For example, the demand for the currency of Roasterland changes when other countries want more (or less) of Roasterland's goods, services, and assets.
The Bottom Line
Currently, the three ways it does this are: Modifying the interest rate that it pays on banks' reserve balances. Altering the discount rate it charges banks that wish to borrow from it. Adjusting the overnight reverse repo rate it pays to financial institutions for temporary overnight deposits.

In India, M3 is the most commonly used measure of money supply.
Influencing interest rates, printing money, and setting bank reserve requirements are all tools central banks use to control the money supply. Other tactics central banks use include open market operations and quantitative easing, which involve selling or buying up government bonds and securities.
The primary way in which the Fed increases or decreases the supply of money is through open market operations (which involve the purchase or sale of government bonds).
The Fed uses three primary tools in managing the money supply and pursuing stable economic growth: reserve requirements, the discount rate, and open market operations. Each of these impacts the money supply in different ways and can be used to contract or expand the economy.
The most widely used tool by the Fed is open market operations, which refers to the purchasing and selling of government securities (bonds) to adjust the money supply.

The various types of money supply, including M1, M2, M3, and M4, represent different measures of the total amount of money circulating within an economy. These measures offer insights into the liquidity and overall monetary conditions of an economy, with M3 often regarded as the most commonly used measure.
This reduces the consumption rate in the economy and the production level. In turn, this negatively affects the country's gross domestic product and causes a fall in the competition level of the economy. All these factors coalesce to create an economic recession or downturn.
What is M1 M2 M3 M4 MCA?
The largest terminal branch of the internal carotid artery, the MCA divides into four main surgical segments, denominated M1 to M4. The M1 segment extends from the ending of the internal carotid artery, perforating the brain up to its division. The M2 segment bifurcates or occasionally trifurcates.
A change in interest rates is one way to make that correspondence happen. A fall in interest rates increases the amount of money people wish to hold, while a rise in interest rates decreases that amount. A change in prices is another way to make the money supply equal the amount demanded.
Banks have little incentive to maintain excess reserves because cash earns no return and may even lose value over time due to inflation. Thus, banks normally minimize their excess reserves, lending the money to clients rather than holding it in their vaults.
Each measure captures a different level of liquidity and accessibility. M1 includes the most readily available forms like cash and checking accounts, while M2 adds less liquid assets like savings deposits. M3 further expands with even less liquid options, giving a comprehensive picture of money in the economy.
M0: The total of all physical currency including coinage. M0 = Federal Reserve Notes + US Notes + Coins. It is not relevant whether the currency is held inside or outside of the private banking system as reserves.
