What Is Currency Intervention?
Intervention (from Latin interventio — intervention) is a term used in economic theory to describe the involvement of central banks or other organizations that manage a country’s financial system in the position of the national currency on the global market.
In other words, currency intervention refers to operations conducted by a central bank involving the purchase or sale of its country’s currency to maintain its exchange rate. This concept also includes targeted operations related to the buying and selling of foreign currency, with the aim of limiting the movement of the currency rate within specific upper or lower limits. The goal of intervention is to regulate the exchange rate to a specific level.
What Is the Purpose of Intervention in the Foreign Exchange Market?
Currency intervention essentially involves the regular buying or selling of the national currency. These transactions are carried out by representatives of the central bank of the country that issues the currency. The main and first objective of currency intervention is solely the interests of the country, specifically its economic sector. It can be said that currency intervention is a kind of lever in the field of monetary policy.
In such cases, there are always fluctuations in price during the buying and selling of currency. For this, the central bank uses certain strategies:
- To increase the exchange rate of the national currency, central bank employees need to sell as much foreign currency as possible. At the same time, they buy all the national currency. In this way, they can significantly reduce the demand for foreign currency.
- A completely opposite situation occurs when the exchange rate of the national currency is lowered. In simple terms, the central bank buys as much foreign currency as possible and tries to sell the national currency. As a result, the exchange rate of the foreign currency should rise, while the national currency should fall.
What Types of Central Bank Interventions Are There?
There are several classifications of interventions. The most common one is as follows:
- Open
The central bank announces the exact amount and time of the transaction.
- Verbal
This method is a form of misinformation. The central bank announces its intention to conduct an intervention, after which the market becomes active, volatility increases. However, if no intervention takes place, the price quickly returns to its usual value.
- Indirect
The most unpredictable option, as the intervention is carried out by commercial banks at the instruction of the central bank. Traders particularly dislike such interventions because they cause rapid price movements and introduce nervousness into the market.
Interventions differ by the number of participants. They are divided into:
- One-sided
Such interventions are often ineffective or less effective, as the desire of one side is often insufficient to stabilize the currency.
- Joint
These interventions are considered more serious, as two central banks express the intention to change the situation on the market.
- Multilateral
This type of intervention is practically destined for success. If the parties reach an agreement, they can easily change the direction of long-term trends. An example of multilateral intervention is the meeting of the ‘Group of Seven’, where it was decided to support Japan after the 2011 earthquake. Within a few days, the Japanese yen fell by two percent due to coordinated actions by the ECB, the US Federal Reserve, and the Bank of Japan.
The third classification divides interventions based on direction:
- Intervention against the trend aims to return the exchange rate to its previous level.
- Intervention with the trend aims to accelerate the change in the exchange rate. Intervention with the trend helps to ‘accelerate’ a weak or barely noticeable trend.
The main impact of intervention occurs through the mass purchase or sale of currency, securities, and other financial assets. The main goal of intervention is to normalize the state of the economy and financial system of the country, stabilize prices, etc.
What Are the Results of Interventions?
The result of intervention is usually a decrease or increase in the exchange rate, depending on the purpose of the intervention. Intervention is considered an extreme measure of influence on the country’s currency system, so countries resort to it only in rare cases when there is no other option.
It should be noted that conducting currency interventions is almost not a market method. There are certain conditions to ensure the success of the intervention. One of these conditions is a large reserve of financial resources of the central bank.
