Currency intervention can be a powerful tool for countries to influence the value of their currency in global trade and economy. Central banks can buy or sell their own currency to impact exchange rates, which can have far-reaching effects on trade balances and economic growth.
A notable example is Japan's currency intervention in 2013, where the Bank of Japan purchased a significant amount of yen to weaken its value. This move was aimed at boosting exports and stimulating economic growth.
Currency intervention can be done through various methods, including spot market intervention and forward market intervention. The goal is to stabilize or manipulate the exchange rate to achieve desired economic outcomes.
In the case of Japan's intervention, the Bank of Japan's actions were successful in weakening the yen, which led to a significant increase in exports and economic growth.

Purposes and Effects
Currency intervention can be a powerful tool for governments to influence the value of their currency.
One of the main purposes of currency intervention is to stabilize the exchange rate, which can help to boost exports and economic growth.
By selling or buying currency on the foreign exchange market, governments can increase or decrease the supply of their currency, thereby influencing its value.
This can have a significant impact on trade balances and economic indicators.
Purpose of Currency Intervention
Currency intervention is a deliberate action taken by a country's central bank to influence the value of its currency. Foreign exchange interventions can be made for two main reasons.
The primary goal of these interventions is to stabilize the currency and reduce volatility in the foreign exchange market. This can be achieved by buying or selling currencies to influence supply and demand.
In some cases, currency intervention is used to increase exports by making the currency more attractive to foreign buyers. By depreciating the currency, a country can make its exports cheaper and more competitive in the global market.
However, the effectiveness of currency intervention in achieving these goals is still debated among economists. Despite this, many countries continue to use currency intervention as a tool to manage their economic policies.

Effectiveness of Currency Intervention

Studies have shown that currency intervention can be highly effective, with one large empirical study finding a success rate of around 80% in managing currency volatility.
A meta-analysis of 300 different estimations on the effectiveness of currency intervention found that, on average, a $1 billion dollar purchase can depreciate a domestic currency by 1%.
Currency intervention is often used to control exchange rate volatility, which is achieved by buying or selling a currency in the foreign exchange market.
Some countries, like Brazil, Japan, Mexico, Sweden, Thailand, and Turkey, frequently intervene in the foreign exchange market to control market rates and stabilize their currencies.
These interventions can also be used to weaken a country's currency relative to others, making exports more attractive to international buyers.

Importance of Currency in Trade
Currency plays a vital role in trade, and its importance cannot be overstated. It's the backbone of international trade, facilitating the exchange of goods and services between countries.

Trade happens through the exchange of money, making currency a crucial influence on trade. The qualities of the traded goods or services themselves are equally important, but currency can be just as influential.
Government intervention in currency markets can distort trade flows and undermine free trade agreements. This is because governments may subsidize their exports, forcing the market to ignore normal pressures of supply and demand.
Free trade supports U.S. exports and American jobs, but it requires free trade in currencies. This means that currency exchange rates must be left to the market forces of supply and demand.
Here are some key points to consider:
- Currency is essential for international trade.
- Government intervention in currency markets can distort trade flows.
- Free trade in goods and services requires free trade in currencies.
- Subsidizing exports through currency manipulation undermines free trade agreements.
Types of Currency Intervention
Currency intervention can take many forms, and understanding the different types is crucial for traders and investors. There are several types of currency intervention, which can be grouped based on the actions of the financial regulator.
Verbal currency intervention, also known as Verbal CI, is not a financial transaction at all. It's simply a statement by the financial regulator indicating the need for foreign exchange intervention, which can provoke a certain effect on the volatility of exchange rates.

Real currency intervention, or Direct CI, involves a real purchase or sale of national currency, which can lead to changes in the market. This type of intervention is popular among traders who can prepare and play on the volatility of exchange rates.
Indirect CI is similar to Direct CI, but the intervention is carried out by several large banks to which the Central Bank gives the necessary powers. This type of intervention can lead to strong and unpredictable fluctuations in the foreign exchange market.
Currency interventions can also be divided into non-sterile and sterile CI. Non-sterile CI occurs when buying or selling national currency increases or decreases the country's monetary base. Sterile CI, on the other hand, occurs when buying or selling national currency does not change the country's monetary base.
Here are the different types of currency intervention based on the number of participating countries:
Multilateral CI is considered the most effective type of currency intervention, often used when several countries want to change the national currency in a country affected by an economic crisis.
Historical and Modern Context

Historical context is crucial to understanding currency intervention. The Bretton Woods system of fixed exchange rates was a cornerstone of the Cold War-era United States, but it dissolved between 1968 and 1973 due to President Nixon's suspension of the dollar's convertibility to gold in 1971.
The end of the traditional Bretton Woods system led to widespread currency management, but not universal adoption. Central banks were free to choose their own exchange arrangement, such as allowing their currency to float freely or pegging it to another currency.
The 2008-2013 period saw a significant shift in currency management, as emerging market economies had to re-examine their foreign exchange market intervention strategies due to huge swings in capital flows.
In modern times, China's currency intervention and foreign exchange holdings are unprecedented, and it's common for countries to manage their exchange rate to make their exports cheap.

Historical Context
The Bretton Woods system of fixed exchange rates was a key part of the Cold War-era United States' economic policies. This system helped maintain exchange rates within prescribed margins, but it ultimately failed due to President Richard Nixon's suspension of the dollar's convertibility to gold in 1971.

The end of the Bretton Woods system in the early 1970s led to a shift in currency management, where countries were free to choose their own exchange arrangements. This change allowed countries to adopt various exchange systems, such as floating their currencies freely or pegging them to another currency.
The traditional Bretton Woods system was dissolved between 1968 and 1973, marking a significant turning point in global currency management. This period saw the rise of floating exchange rates, which have remained a key feature of the global economy ever since.
In the aftermath of the global financial crisis of 2008, emerging market economies had to reassess their foreign exchange market intervention strategies. This was due to huge swings in capital flows, which put pressure on these economies to intervene in currency markets.

Modern Examples
In modern times, some countries have become frequent currency manipulators. Japan and Switzerland are examples of longstanding advanced and developed economies that have been known to intervene in the foreign exchange market.

The Peterson Institute identifies four groups that stand out as frequent currency manipulators, including newly industrialized economies such as Singapore and developing Asian economies such as China. China's currency intervention and foreign exchange holdings are unprecedented.
It's common for countries to manage their exchange rate via central bank to make their exports cheap. This method is being used extensively by the emerging markets of Southeast Asia, in particular.
Countries like Brazil, Japan, Mexico, Sweden, Thailand, and Turkey often intervene to control market rates. Brazil, Japan, Mexico, Sweden, Thailand, and Turkey are among the countries that frequently intervene in the foreign exchange market.
A foreign exchange intervention is an action taken by a central bank usually to control exchange rate volatility. This stability is achieved by buying or selling a currency in the foreign exchange market.
Countries may intervene as well to weaken their currencies relative to those of other countries in an effort to make the prices for their exports more attractive to international buyers.

When Did the Fed Conduct?
The Federal Reserve has a history of intervening in foreign exchange markets. The New York Fed last intervened in March 2011 when it sold Japanese yen.
The Fed's actions in the foreign exchange market are a significant aspect of its overall monetary policy. In 2011, the New York Fed's intervention in the yen market was a notable event.

Mechanics and Risks
The Bank of Canada uses its holdings of foreign currencies in the Exchange Fund Account to conduct foreign exchange market intervention. The Fund holds U.S. dollars, euros, British pounds, and Japanese yen.
To moderate a decline in the Canadian dollar's value, the Bank buys Canadian dollars in foreign exchange markets in exchange for other currencies, mainly U.S. dollars. This boosts demand for Canadian dollars and helps support the dollar's value.
If the government and the Bank want to slow the currency's rate of appreciation, they sell Canadian dollars on behalf of the government and purchase other currencies. By selling Canadian dollars, the Bank increases the supply of Canadian dollars in foreign exchange markets, providing some resistance to the upward movement in the currency.

How It's Done

Central banks use various methods to intervene in the foreign exchange market, but the most common approach is to buy or sell currencies directly. They can also use sterilized intervention, a policy that attempts to influence the exchange rate without changing the monetary base.
To buy or sell currencies, central banks typically use the Exchange Fund Account, which holds U.S. dollars, euros, British pounds, and Japanese yen. They can also use domestic-currency-denominated bonds to sterilize the effects on the monetary base.
Central banks can intervene in the foreign exchange market for various purposes, including creating a fixed price range, maintaining a balance between supply and demand, and protecting the economy from negative factors due to volatility in the national currency.
To achieve these goals, central banks can buy or sell currencies on the foreign exchange market, the stock market, the currency exchange, the commodity market, or through currency auctions. They can also use indirect methods, such as capital controls and exchange controls, to influence the exchange rate.
A unique perspective: Currency Exchange Buy or Sell Rate

Here are some common methods used by central banks to intervene in the foreign exchange market:
- Buying foreign currency with a simultaneous "injection" into the national currency market, resulting in the depreciation of the national currency.
- Selling foreign currency with a simultaneous purchase of national currency, resulting in the appreciation of the national currency due to a sharp jump in demand.
- Selling or buying gold reserves to strengthen or weaken the national currency.
Risks of Currency Intervention
Currency intervention can be a double-edged sword, and it's essential to understand the risks involved. Foreign exchange interventions can undermine a central bank's credibility if it fails to maintain the stability of its country's currency.
A clear example of this is the 1994 currency crisis in Mexico, which was precipitated by the central bank's attempts to defend the national currency from speculation. The Asian financial crisis of 1997 was also partly caused by currency intervention.
The consequences of failed intervention can be severe, and it's crucial to carefully consider the potential outcomes before taking action.
Regulation and Policy
The Bank of Canada intervenes in foreign exchange markets on behalf of the federal government to counter disruptive short-term movements in the Canadian dollar.
Any intervention is governed by an intervention policy, which is established by the government in close consultation with the Bank of Canada. This policy was changed in September 1998 due to the ineffectiveness of intervening to resist movements in the exchange rate caused by changes in fundamental factors.
Recommended read: Does Canada Have Their Own Currency
The current policy is to intervene in foreign exchange markets on a discretionary, rather than a systematic, basis and only in the most exceptional of circumstances. This means intervention might be considered if there are signs of a serious near-term market breakdown or extreme currency movements threaten the conditions that support sustainable long-term growth of the Canadian economy.
Is the Federal Reserve Allowed to Operate?
The Federal Reserve is a powerful institution, and understanding its authority is crucial.
It's authorized by the Federal Open Market Committee (FOMC) to intervene in the economy.
The FOMC is responsible for setting monetary policy, including setting interest rates and buying or selling government securities.
In certain situations, the New York Fed is allowed to conduct foreign exchange interventions to maintain market orderliness.
This means they can intervene in foreign exchange markets to stabilize the value of the US dollar.
The Federal Reserve's ability to operate is not limited to domestic markets, they also have a role in international markets.
Their operations are guided by the FOMC's decisions, which are made in the best interest of the US economy.

Policy on Currency Intervention
Central banks have the authority to intervene in foreign exchange markets to stabilize the value of their currency. The Bank of Canada, for example, has intervened in the past to counter disruptive short-term movements in the Canadian dollar.
In some cases, intervention is governed by a policy established by the government in consultation with the central bank. The Bank of Canada's policy, for instance, was changed in 1998 to a discretionary approach, only intervening in exceptional circumstances.
Intervention can be considered if there are signs of a serious near-term market breakdown or if extreme currency movements threaten the conditions that support sustainable long-term growth. The Bank of Canada might also intervene to help stabilize the currency and signal a commitment to back up the intervention with further policy actions.
Coordinated intervention is also possible, where multiple countries work together to support a specific currency. The Bank of Canada, for example, participated in a concerted intervention in 2011 to support the Japanese yen.
Not all countries intervene in the foreign exchange market at the same frequency. While the U.S. intervenes infrequently, some countries like Brazil, Japan, Mexico, Sweden, Thailand, and Turkey often intervene to control market rates.

Understanding Currency Intervention

Understanding Currency Intervention is a complex process that requires careful consideration of several factors.
Central banks face two main difficulties in determining the timing and amount of intervention, making it often a judgment call rather than a cold, hard fact.
The success of a foreign exchange intervention depends on how the central bank sterilizes the impact of its interventions, as well as on general macroeconomic policies set by the government.
Some countries, like Brazil, Japan, Mexico, Sweden, Thailand, and Turkey, intervene frequently to control market rates, whereas the U.S. intervenes infrequently.
Currency intervention is an action taken by a central bank to control exchange rate volatility by buying or selling a currency in the foreign exchange market.
This operation can be conducted by the Central Bank or the country's treasury, and it can involve not only the national currency but also foreign currencies and gold reserves.

What is Currency Intervention?
Currency intervention is a tool used to influence the economy, and it's a fairly popular method among central banks and treasuries.
The central bank is the primary entity responsible for conducting currency intervention, but sometimes the country's treasury gets involved too.
Not only can currency intervention affect the national currency, but it can also impact foreign currencies and even gold reserves.
This operation significantly changes the situation in the foreign exchange market, giving traders more opportunities to earn money by speculating exchange rates.
Currency intervention is a double-edged sword, creating both risks and rewards, and it all depends on the trader's experience and desires.

Central banks face difficulties in determining the timing and amount of intervention, which is often a judgment call rather than a cold, hard fact.

The amount of reserves, the type of economic trouble facing the country, and ever-changing market conditions require research and understanding before determining how to take a productive course of action.
Some countries, like Brazil, Japan, Mexico, Sweden, Thailand, and Turkey, often intervene to control market rates, while the U.S. intervenes infrequently.
A corrective intervention may have to be taken shortly after the first attempt if the initial intervention does not have the desired effect.
Results of certain interventions can have unintended effects on a country's inflation rate, which is why careful consideration is needed before intervening in the foreign exchange market.

Country-Specific Information
Japan's central bank, the Bank of Japan, has a history of intervening in the foreign exchange market to influence the value of the yen. In 1998, the bank increased the commercial bank current account balance to ¥35 trillion as part of a reserve targeting program.
The Bank of Japan's actions were aimed at stimulating the economy and stabilizing the financial system during a period of deflation. The bank's policy interest rate was already virtually at zero, and the nominal interest rate could not become negative due to the zero bound problem.
Japan held $1.27 trillion in foreign reserves in 2013, which it used to buy bonds issued by the European Stability Mechanism and euro-area sovereigns in an attempt to weaken the yen.

US Dollar

The US dollar is the world's primary reserve currency. This means that countries often hold US dollars in their central banks to stabilize their economies.
Its status as a reserve currency gives the US a significant influence over global currency markets. The Federal Reserve system uses a tool called the System Open Market Account to intervene in currency markets.
In 2014, several large investment banks were fined for currency manipulation. These banks included UBS, JPMorgan Chase, Citigroup, HSBC, and the Royal Bank of Scotland.

Japanese Yen
The Japanese yen has had its fair share of challenges, particularly during the 1990s when Japan experienced a long deflationary period.
From 1989 to 2003, Japan's economy was in a downward spiral, with stagnating output, negative inflation rates, and increasing unemployment.
The Bank of Japan, having become independent in 1998, aimed to stimulate the economy by ending deflation and stabilizing the financial system, but was constrained by the zero bound problem.
Here's an interesting read: Japan New 500 Yen Coin
In response, the Bank of Japan launched a reserve targeting program, increasing the commercial bank current account balance to ¥35 trillion.
The Ministry of Finance used those funds to purchase $320 billion in U.S. treasury bonds and agency debt.
By 2014, critics accused the Bank of Japan of artificially devaluing the yen, which led to a significant trade deficit with the US, amounting to $261.7 billion.
Japanese Finance Minister Taro Aso stated in 2013 that Japan planned to use its foreign exchange reserves to buy bonds issued by the European Stability Mechanism and euro-area sovereigns to weaken the yen.
Japan held $1.27 trillion in foreign reserves by 2013, which it used to intervene in foreign exchange markets.
In 2022, Japan intervened again on foreign exchange markets in the context of a dollar appreciation.

Qatari Riyal
The Qatari riyal has had its fair share of volatility, especially during the first eight months of the Qatar diplomatic crisis. This period saw significant fluctuations in the exchange rates of the Qatari riyal.

In 2019, the Qatar Financial Centre Regulatory Authority fined the First Abu Dhabi Bank $55 million for failing to cooperate in a probe into possible manipulation of the Qatari riyal. This incident highlights the importance of regulatory bodies in maintaining financial integrity.
The value of the Qatari riyal was allegedly manipulated by the Crown Prince of Abu Dhabi, Mohammed bin Zayed, in a coordinated attack aimed at depleting the country's foreign exchange reserves. This action was reportedly carried out with the help of financier David Rowland and his private banking service, Banque Havilland.
A presentation made by an ex-Banque Havilland analyst in 2017 called for the attack on the Qatari riyal, stating "Control the yield curve, decide the future." This quote illustrates the extent of the manipulation and the potential consequences for the country's economy.

Chinese Yuan
The Chinese yuan has been a hot topic in the world of economics.
In the 1990s and 2000s, there was a marked increase in American imports of Chinese goods.
Expand your knowledge: Us Currency vs Chinese Currency

This led to China's central bank allegedly devaluing the yuan by buying large amounts of US dollars with yuan, thus increasing the supply of the yuan in the foreign exchange market.
By December 2012, China's foreign exchange reserve held roughly $3.3 trillion, making it the highest foreign exchange reserve in the world.
Roughly 60% of this reserve was composed of US government bonds and debentures.
There has been much disagreement on how the United States should respond to Chinese devaluation of the yuan.
Paul Krugman argued in 2010, that China intentionally devalued its currency to boost its exports to the United States and as a result, widening its trade deficit with the US.
Krugman suggested at that time, that the United States should impose tariffs on Chinese goods.

Frequently Asked Questions
What is an example of currency manipulation?
Currency manipulation occurs when a country intentionally weakens its currency to boost exports and attract foreign investment, often by selling its currency on the foreign exchange market. This can create a trade surplus and increase domestic demand, but can also have negative effects on the economy and trade relationships
