Equilibrium in the financial market requires that

Explanation

This question is asking about what is needed for equilibrium to be reached in the financial market. The options are A, B, C, and D.

Equilibrium refers to a balance between supply and demand. In the financial market, this means that the amount of money being supplied should be equal to the amount of money being demanded. This is where option A, money supply equals money demand, comes in. This option is correct because it accurately describes what is needed for equilibrium to be reached in the financial market.

Option B, money supply equals reserves demand, is incorrect because it does not directly relate to the concept of equilibrium in the financial market. Reserves demand refers to the amount of money that banks hold in reserves, which is not directly related to the supply and demand of money in the financial market.

Option C, checkable deposits equal overall supply of money, is also incorrect because it only relates to a specific type of money (checkable deposits) and does not take into account other forms of money or the concept of demand.

Option D, money supply equals overall demand for money, is incorrect because it only considers the supply of money and not the demand for it. As mentioned earlier, equilibrium requires a balance between both supply and demand.

In conclusion, option A is the correct answer because it accurately describes what is needed for equilibrium to be reached in the financial market.
