Foreign Exchange Interventions by Central Banks: Main Talking Points
Central banks play a crucial role in the foreign exchange market by intervening to protect the value of their national currency. Understanding the different types of interventions and their impact is essential for forex traders. This article explores the various aspects of central bank interventions in detail.
What is foreign exchange intervention?
Foreign exchange intervention refers to the actions taken by central banks to stabilize the exchange rate or correct market misalignments. It involves the buying or selling of foreign currency, which is often accompanied by adjustments to the money supply to counter any negative effects on the local economy. One of the techniques used in intervention is sterilized intervention, which we will discuss further along with other currency intervention methods.
How forex traders can trade a central bank intervention
Trading around central bank interventions requires careful consideration due to the high volatility it can introduce into the market. Forex traders must establish an appropriate risk-to-reward ratio and implement prudent risk management strategies to mitigate potential losses. It is important to note that central banks intervene when the current trend is contrary to their desired exchange rate. Consequently, trading during central bank interventions is akin to trading reversals. Additionally, traders must be aware that the forex market often anticipates central bank interventions, leading to movements against the long-term trend before the intervention takes place.
Why do central banks intervene in the foreign exchange market?
Central banks intervene in the foreign exchange market with the objective of stimulating the economy or maintaining a desired foreign exchange rate. When the local currency appreciates to a level that makes domestic exports more expensive, central banks may intervene by buying foreign currency and selling local currency. This intentional adjustment of the exchange rate aims to benefit the local economy. A successful example of central bank intervention can be observed during the Bank of Japan’s efforts to depreciate the yen against the US dollar.
Successful central bank intervention example:
The Bank of Japan identified the yen’s strength against the US dollar as unfavorable and swiftly intervened to depreciate the yen. This intervention led to a significant increase in the USD/JPY currency pair. The impact of the intervention can be seen in the chart below.
However, it is crucial to note that not all central bank interventions yield immediate positive results. In some instances, interventions fail to strengthen the currency as intended, leading to continued appreciation of the foreign currency. The chart below depicts a failed intervention in the USD/BRL (US dollar/Brazilian Real) currency pair.
Failed central bank intervention example:
The central bank’s interventions aimed at stopping the decline in the Brazilian Real failed to immediately strengthen the currency against the US dollar. Despite their efforts, the US dollar continued to rise significantly. This example highlights that central bank interventions do not always produce the desired outcome.
How does currency intervention work?
Central banks have multiple options when it comes to currency intervention, which can be classified as direct or indirect. Direct intervention has an immediate and visible effect on the forex market, while indirect intervention achieves the central bank’s objectives through less invasive means. Examples of each type are as follows:
- Operational Intervention: This form of intervention involves the central bank buying and selling foreign and local currency in order to manipulate the exchange rate to a targeted level. The sheer size of these transactions has a considerable impact on the market.
- Jawboning: Jawboning is an example of indirect intervention, whereby the central bank publicly acknowledges its readiness to intervene if the local currency reaches an undesirable level. By making these statements, the central bank attempts to influence market sentiment and encourage traders to collectively adjust the currency’s value.
- Concerted Intervention: When multiple central banks express concerns over exchange rates, concerted intervention may occur. This approach combines both jawboning and operational intervention. If several central banks increase their verbal intervention efforts, it is likely that at least one of them will conduct operational intervention to drive the exchange rate in the desired direction.
- Sterilized Intervention: Sterilized intervention involves two actions by the central bank to influence the exchange rate while keeping the monetary base unchanged. First, the central bank sells or purchases foreign currency, and then it conducts open market operations by selling or buying government securities equal to the size of the initial transaction.
