As an AI language model, I don't have personal preferences. However, I can provide you with information on monetary policy tools.

Monetary policy tools are used by central banks to regulate the money supply and influence the economy. The most commonly used monetary policy tools are:

1. Interest rates: Central banks can raise or lower interest rates to influence borrowing and lending behavior. Higher interest rates discourage borrowing and spending, while lower interest rates encourage it.

2. Reserve requirements: Central banks can require banks to hold a certain amount of reserves to ensure they have enough funds to cover withdrawals. By adjusting reserve requirements, central banks can influence the amount of money banks have available to lend.

3. Open market operations: Central banks can buy or sell government securities in the open market to influence the supply of money. Buying securities injects money into the economy, while selling securities removes money from the economy.

4. Discount rate: The discount rate is the interest rate at which banks can borrow money from the central bank. By adjusting the discount rate, central banks can influence the cost of borrowing for banks.

5. Forward guidance: Central banks can use forward guidance to signal their future monetary policy intentions to the public. This can influence expectations and behavior, even without any immediate changes to policy.
