In the articles on present value, we learnt that the value of a dollar today is not the same as it will be 10 years from now. Then, we came across annuities which are a powerful mechanism that ensure that the nominal value of the payments remain the same throughout the years whereas its internal […]
The Glitz and Glamour of Finance Beckons Many Many management graduates and those working towards entering business schools often aspire to be financial professionals and dream of being an investment banker, private equity specialist, stock analyst, or a pure play banker in the plain vanilla banking. Indeed, with the globalization of finance and the integration […]
Although accounting may be heralded as being the language of the business, it is definitely not error-free. This has been highlighted by the fact that accounting scams have occurred one after the other for many years. In fact, even after stricter regulation and tightening of accounting rules, accounting scams just don’t cease to stop. As […]
Retail investors across the world do not have a high level of knowledge when it comes to money markets. This is because of the fact that money markets have been largely invisible to retail investors. For a significant amount of time, money markets have only been used by large corporations, banks, and other entities to […]
Depreciation is an important concept in capital budgeting. This is because it is a non cash expense and ideally should not have any effect on the cash flows. This is the reason why it is added back during cash flow calculations. Since the amount of depreciation never actually left our bank account in the form […]
Central Banks do not intervene often in the Forex market. In fact, the intervention by Central Banks can be considered to be a sign of significant economic weakness in a currency. As a result, Central Bank intervention usually only happens when the currency is under some sort of crisis. This could be a genuine economic crisis like the 2008 crisis or the Euro crisis. Alternatively, it could also be a speculative attack that a country is facing.
There are multiple ways in which Central Banks can intervene in the markets. Some of these ways require more commitment than the others and are also more effective than the others. In this article, we have listed down the 4 prominent types of Central Bank interventions.
The traders and other participants in the market are aware of the monetary might of the Central Banks and therefore more often than not, the currency range declared by the Central Bank becomes the range in which the currency automatically starts trading without any Central Bank intervention.
Jawboning is essentially a technique where the threat of a Central Bank intervention to reset the rates is used to reset the rates without the intervention ever taking place! Jawboning is particularly effective when Central Banks have the reputation for periodic intervention into the open markets.
Concerted intervention only takes place when many Central Banks share the same objective i.e. they want to control a particular exchange rate. Usually jawboning from all Central Banks gets the desired results. One or two Central Banks may actually have to intervene. However, only in the rarest of the rare cases do multiple Central Banks have to conduct operational interventions to correct a currency rate.
Let’s understand this with the help of an example. Let’s say that the Fed is concerned about the dollar depreciation against the Indian rupee and wants to take action to change this. In this case, the Fed will sell Indian rupee in the market and buy dollars from it. This will lead to two effects. Firstly, it will increase the supply of the rupee and secondly it will decrease the supply of the dollars. The objective of the Fed in the Forex market will be fulfilled.
However, there is also a side effect to this policy. The number of dollars in the United States economy would suddenly increase as a result of this transaction. This could cause inflation and other economic issues as well. Therefore, to counter the situation, the Fed would sell United States denominated bonds in the market. As a result, it will remove dollars from the domestic market (sterilizing the effect). The dollars will now be replaced with the government obligation and therefore the inflation and other effects will be controlled.
