How Does Forex Compare to Other Markets?

Unlike stocks, futures, or options, currency trading does not take place on a regulated exchange, and it is not controlled by any central governing body. There are no clearing houses to guarantee trades, and there is no arbitration panel to adjudicate disputes. All members trade with each other based on credit agreements. Essentially, business in the largest, most liquid market in the world depends on nothing more than a metaphorical handshake.

At first glance, this ad-hoc arrangement is bewildering to investors who are used to structured exchanges such as the New York Stock Exchange (NYSE) or the Chicago Mercantile Exchange (CME). However, this arrangement works in practice. Self-regulation provides effective control over the market because participants in FX must both compete and cooperate.

Additionally, reputable retail FX dealers in the United States become members of the National Futures Association (NFA), and by doing so, FX dealers agree to binding arbitration in the event of any dispute. Therefore, it is critical that any retail customer who contemplates trading currencies does so only through an NFA member firm.1

The FX market is different from other markets in other unique ways. Traders who think that the EUR/USD might spiral downward can short the pair at will. There is no uptick rule in FX as there is in stocks. There are also no limits on the size of your position (as there are in futures). Thus, in theory, a trader could sell $100 billion worth of currency if they have sufficient capital.

In another context, a trader is free to act on information in a way that would be considered insider trading in traditional markets. For example, a trader finds out from a client who happens to know the governor of the Bank of Japan (BOJ) that the BOJ is planning to raise rates at its next meeting; the trader is free to buy as much yen as they can. There is no such thing as insider trading in FX—European economic data, such as German employment figures, are often leaked days before they are officially released.

Before we leave you with the impression that FX is the Wild West of finance, note that this is the most liquid and fluid market in the world. It trades 24 hours a day, from 5 p.m. EST Sunday to 4 p.m. EST Friday, and it rarely has any gaps in price.2 Its sheer size and scope (from Asia to Europe to North America) make the currency market the most accessible in the world.

The Bottom Line

Every currency has specific features that affect its underlying value and price movements relative to other currencies in the forex market. Understanding the factors that move a currency is a pivotal step in becoming a savvy participant in the forex market. The U.S. dollar, the euro, the yen, the British pound, the loonie, and the Swiss franc are major currencies to watch.

The Canadian Dollar

The Canadian dollar, nicknamed the loonie, is also a commodity currency, meaning that it often moves in step with the commodities markets—notably crude oil, precious metals, and minerals. With Canada being such a large exporter of such commodities, the loonie often reacts to movements in underlying commodities prices, especially that of crude oil.15 Traders often trade the Canadian dollar to speculate on the movements of commodities or to hedge positions in the commodities market

The Australian Dollar

Also known as the Aussie, the Australian dollar is one of the major currencies of the Asia-Pacific region. The Aussie is considered one of the foremost commodity currencies, meaning that its value can be affected by price shifts in Australia’s major exports.

The AUD-USD trading pair now accounts for 6.37% of global forex volume, beating the dollar pairings for both the Swiss Franc and the Canadian Dollar.

The Great British Pound

The Great British pound, also known as the pound sterling, is the fourth most traded currency in the forex market.2 Although the U.K. was an official member of the European Union, the country never adopted the euro as its official currency for a variety of reasons, namely historic pride in the pound and maintaining control of domestic interest rates.13 As a result, the pound is sometimes viewed as pure-play in the United Kingdom.

Forex traders will often estimate the value of the British pound based on the overall strength of the British economy and the political stability of its government. Due to its high value relative to its peers, the pound is also an important currency benchmark for many nations and represents a very liquid component in the forex market. The British pound also acts as a large reserve currency due to its historically high relative value compared to other global currencies.8

Being located in close proximity to the world’s largest consumer base—the United States—the Canadian economy and the Canadian dollar are highly correlated to the U.S. economy and movements in the U.S. dollar as well.

The Japanese Yen

The Japanese yen is easily the most traded of Asian currencies and viewed by many as a proxy for the underlying strength of Japan’s manufacturing and export-driven economy. As Japan’s economy goes, so goes the yen (in some respects). Forex traders also watch the yen to gauge the overall health of the Pan-Pacific region as well, taking economies such as South Korea, Singapore, and Thailand into consideration, as those currencies are traded far less in the global forex markets.2

The yen is also well known in forex circles for its role in the carry trade (seeking to profit from the difference in interest rates between two currencies). The strategy involves borrowing the yen at next to no cost (due to low-interest rates) and using the borrowed money to invest in other higher-yielding currencies around the world, pocketing the rate differentials in the process.12

With the carry trade being such a large part of the yen’s presence on the international stage, the constant borrowing of the Japanese currency has made appreciation a difficult task. Though the yen still trades with the same fundamentals as any other currency, its relationship to international interest rates, especially with the more heavily traded currencies such as the U.S. dollar and the euro, is a large determinant of the yen’s value.

The Euro

The euro has become the second most traded currency behind the U.S. dollar.2 The official currency of the majority of the nations within the eurozone, the euro was introduced to the world markets on Jan. 1, 1999, with banknotes and coinage entering circulation three years later.7

Along with being the official currency for most eurozone countries, many nations within Europe and Africa peg their currencies to the euro, for much the same reason that currencies are pegged to the U.S. dollar—to stabilize the exchange rate. As a result, the euro is also the world’s second-largest reserve currency.8

With the euro being a widely used and trusted currency, it is prevalent in the forex market and adds liquidity to any currency pair it trades with. The euro is commonly traded by speculators as a play on the general health of the eurozone and its member nations. Political events within the eurozone can also lead to large trading volumes in the euro, especially in relation to nations that saw their local interest rates fall dramatically at the time of the euro’s inception, notably Italy, Greece, Spain, and Portugal.910 The euro may be the most “politicized” currency actively traded in the forex market.

The U.S. Dollar is the dominant currency in foreign exchange markets. Measured by volume, the eight most common currency pairings involve the U.S. dollar

The U.S. Dollar

The U.S. dollar, which is sometimes called the greenback, is first and foremost in the world of forex trading, as it is easily the most traded currency on the planet.2 The U.S. dollar can be found in a currency pair with all of the other major currencies and often acts as the intermediary in triangular currency transactions. This is because the greenback acts as the unofficial global reserve currency, held by nearly every central bank and institutional investment entity in the world.3

In addition, due to the U.S. dollar’s global acceptance, it is used by some countries as an official currency, in lieu of a local currency, a practice known as dollarization.4 The U.S. dollar also may be widely accepted in other nations, acting as an informal alternative form of payment, while those nations maintain their official local currency.

The U.S. dollar is also an important factor in the foreign exchange rate market for other currencies, where it may act as a benchmark or target rate for countries that choose to fix or peg their currencies to the dollar’s value. China, for instance, has long had its currency, the yuan or renminbi, pegged to the dollar, much to the disagreement of many economists and central bankers.5 Quite often, countries will fix their currencies to the U.S. dollar to stabilize their exchange rates rather than allowing the free (forex) markets to drive the currency’s relative value.

One other feature of the U.S. dollar is that it is used as the standard currency for most commodities, such as crude oil and precious metals. Thus, these commodities are subject not only to fluctuations in value due to the basic economic principles of supply and demand but also to the relative value of the U.S. dollar, with prices highly sensitive to inflation and U.S. interest rates, which can affect the dollar’s value

Real World Example of a Currency Board

Hong Kong has a currency board that maintains a fixed exchange rate between the U.S. dollar and the Hong Kong dollar. Hong Kong’s currency board has a 100% reserve requirement, so all Hong Kong dollars are fully backed with U.S. dollars.1 While the currency board contributed to Hong Kong’s trade with the U.S., it also worsened the impact of the 1997 Asian financial crisis.

Disadvantages of a Currency Board

Currency boards also have downsides. In fixed exchange-rate systems, currency boards don’t allow the government to set their interest rates. That means economic conditions in a foreign country usually determine interest rates. By pegging the domestic currency to a foreign currency, the currency board imports much of that foreign country’s monetary policy.

When two countries are at different points in the business cycle, a currency board can create serious issues. For example, suppose the central bank raises interest rates to restrain inflation during an expansion in the foreign country. The currency board transmits that rate hike to the domestic economy, regardless of local conditions. If the country with a currency board is already in a recession, the rate hike could make it even worse.

In a crisis, a currency board can cause even more damage. If investors offload their local currency quickly and at the same time, interest rates can rise fast. That compromises the ability of banks to maintain legally required reserves and appropriate liquidity levels.

Such a banking crisis can get worse fast because currency boards cannot act as a lender of last resort. In the event of a banking panic, a currency board cannot lend money to banks in a meaningful way.
