Implementing Monetary Policy

Implementing Monetary Policy

Central banks implement the monetary policy using a number of instruments. These affect the aggregate demand through the supply of money, cost of money, and credit availability. The three main tools central banks use to implement monetary policies are discussed below.

Bank Rate Variation Policies

Interest rate is the tool central banks mostly use to express their policy intentions to commercial banks, the entire financial system, and the economy in general. Normally, central banks only transact with commercial banks and other financial institutions. Therefore, when a central bank announces an interest rate, the announcement informs the public of the rate at which it is willing to lend to commercial banks. In the US, unexpected changes in the Fed funds rate are major market-moving events.

When the central bank wishes to reduce the amount of money in circulation within an economy, it could increase its interest rate (also known as policy rate or bank rate). When the interest rate is increased, commercial banks would have to reduce their lending rate because if they were to run short of funds, they would have to borrow from the central bank at the interest rate set by the central bank. Similarly, the central bank would reduce its interest rate if it wished to increase the money circulation within an economy.

Open Market Operations

Open market operations refer to cases where a central bank buys and sells securities in the money market. When there is a rise in price, the central bank sells securities. The commercial bank’s reserves are decreased and, therefore, they cannot be in a position to lend more to the business community. This leads to a decline in investments, and a further rise in prices is halted.

On the other hand, when recessionary forces get going in an economy, the central bank purchases securities, increasing the commercial banks’ reserves. Commercial banks then tend to lend more to businessmen and women who will, in turn, invest more.

Reserve Requirements

The law requires commercial banks to keep a certain percentage of their total deposits in the central bank as a reserve. When there is a rise in prices, the central bank raises the reserve ratios and, therefore, commercial banks are left with less money to lend to the business community.  Consequently, the volume of output, employment, and investment are adversely affected. Eventually, prices will fall. The opposite is also true.

Note that the higher the reserve requirement, the less the money commercial banks can create. Hence, if the central bank wants to reduce the money creation power of commercial banks, it could easily increase the commercial bank’s reserve requirements.

Question

Which of the following is an instrument used to implement monetary policy?

  1. Lender of last resort.
  2. Regulator of currency.
  3. Open market operations.

Solution

The correct answer is C.

An open market operation is an instrument that the central bank uses to buy or sell securities to the public whenever there is too much rise or fall in prices.

B and C are incorrect. They are some of the roles of a central bank.

    Excelente para el FRM 2 Escribo esta revisión en español para los hispanohablantes, soy de Bolivia, y utilicé AnalystPrep para dudas y consultas sobre mi preparación para el FRM nivel 2 (lo tomé una sola vez y aprobé muy bien), siempre tuve un soporte claro, directo y rápido, el material sale rápido cuando hay cambios en el temario de GARP, y los ejercicios y exámenes son muy útiles para practicar.

    So helpful. I have been using the videos to prepare for the CFA Level II exam. The videos signpost the reading contents, explain the concepts and provide additional context for specific concepts. The fun light-hearted analogies are also a welcome break to some very dry content. I usually watch the videos before going into more in-depth reading and they are a good way to avoid being overwhelmed by the sheer volume of content when you look at the readings.

    A great curriculum provider. James sir explains the concept so well that rather than memorising it, you tend to intuitively understand and absorb them. Thank you ! Grateful I saw this at the right time for my CFA prep.

    Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
