To find out all you need to know about the impact of the European debt crisis, just look at the performance of the U.S. dollar in the last three months:

You just can’t argue with the trend seen in the dollar’s performance. There’s a clear argument to make for its longevity, too: While government leaders are getting close to a rescue deal with Greece, even if one does happen, who’s going to make Greece accountable?

Furthermore, why try to predict any outcome? Just look at the dollar, which is solidly above its 200-day moving average. You’ve got to balance the fundamentals with the technicals, and right now, the ingredients are all there.

But the dollar isn’t your only option in these trying times for the euro. The CurrencyShares Euro Trust (NYSEArca: FXE) is down 5% for the year. [ETFs to Ride the Euro's Changing Fortunes.]

Are you bullish or bearish on the euro’s prospects? One way to play your euro sentiment is by using leveraged and inverse ETFs. Speculation in currency trading is highly risky, especially when leverage is added into the mix. Before you jump in, be sure you know what you’re jumping into.

Other currency opportunities can be found in areas well outside Europe. The Canadian dollar, Australian dollar, Mexican peso, Brazilian real and an ETF that holds a basket of currencies have been faring well in the last month:

• CurrencyShares Canadian Dollar Trust (NYSEArca: FXC), up 2.1% in the last month
• CurrencyShares Mexican Peso Trust (NYSEArca: FXM), up 0.7%
• WisdomTree Brazilian Real (NYSEArca: BZF), up 1.7%

While the unemployment rate held steady at 9.7% and 36,000 jobs were lost in February, the number of jobs the economy shed was far less than what economists had been expecting. The impact of the snowstorms on the East Coast may have had a small impact on the final figures, but the Labor Department wouldn’t say how much.

The jobs report quickly had an impact on other areas of the market, primarily easing investors’ fears and encouraging them to take on more risk. That, combined with reassurance from China’s premier that the country would stick to a looser monetary stance, helped boost copper prices by more than 3%. Concerns about China’s demand for metals has weighed on investors, but those fears may be unfounded, as China still intends to be a major consumer of metals. iPath DJ-UBS Copper TR Sub-Index ETN (NYSEArca: JJC) is up nearly 2% this morning.

High-yielding currencies are also leading the charge in the markets this morning, with the dollar gaining ground on the yen and dipping against the euro and other higher-yielding currencies, such as the Australian Dollar.

Australia’s Central Bank Governor Glenn Stevens boosted the overnight cash rate target to 4% from 3.75%, reports Jacob Greber for BusinessWeek. The news strengthened the Australian dollar against a basket of currencies, and brought the Aussie to a 25-year high against the British pound. [Australia ETF: Steady Growth, But Is Inflation Too Low?]

Looking at the numbers, it’s easy to see where the confidence comes from:

• The Central Bank predicts that a rebound in consumer confidence, greater business optimism, higher housing prices, drop in unemployment and signs of an investment boom will further aid the Australian economy.
• Retail sales increased 1.2% in January from December, more than twice the gain expected by economists.
• Australia’s company gross operating profits increased by 2.2% in the fourth quarter of 2009 from the previous quarter, reports James Glynn for The Wall Street Journal. New home sales jumped 9.5% in January from December.
• The Australian Industry Group-PricewaterhouseCoopers Australian Performance of Manufacturing Index rose 2.8 points to 53.8% in February from January. Anything above 50.0 indicates an expansion.
• The TD-Securities/Melbourne Institute Monthly Inflation Gauge increased 0.1% in February from January, and so far this year, the inflation gauge rose 1.9%.

As with any economy, there are roadblocks to watch. According to Netherlands Authority for Financial Markets chairman Hans Hoogervorsttold, the excessive debt taken on by governments around the world may eventually hurt Australia’s economy, writes Lucy Battersby for The Sydney Morning Herald. For example, the stimulus programs in Asian countries will eventually be wound down and demand for Australian resources will start to recede.

On the other hand, Asian economies may exercise caution in unwinding their various stimulus efforts. Doing so will help ensure that the rug isn’t just being pulled out from under any recovery.

An investor with a penchant for trading currencies may consider investing in currency ETFs, which are basically trusts that can be bought and sold through a traditional brokerage, remarks Nick Thomas for Jutia Group. These ETFs are listed on the NYSE Arca, can be traded like stocks and cover a basket of currencies or country-specific currencies. (ETF Trends’ guide to currency ETFs).

Additionally, providers have  also issued currency ETF vehicles that are short, or ultra-short, but most come in the standard “long” ETF.

So far this year, the CurrencyShares Australian Dollar Trust (NYSEArca: FXA) is perhaps the best performer, up 31.1% year-to-date. WisdomTree Dreyfus Brazilian Real (NYSEArca: BZF) Other top performers include CurrencyShares Swedish Krona Trust (NYSEArca: FXS), up 11.6% year-to-date, and CurrencyShares Mexican Peso Trust (NYSEArca: FXM), up 13.1% year-to-date. (How to use foreign currency ETFs to your advantage).

Essentially, most countries other than the United States are preserving the value of their currency, and an investor could have hedged against the falling dollar with some foreign currency ETF allocations. But just because the U.S. dollar is now at a monthly high, it doesn’t mean there aren’t options left. The currency market is one that is always moving and shifting, and some feel that the dollar’s gain this morning is just temporary.

The U.S. Dollar Index didn’t reach its 50-day moving average, and Thomas goes so far as to suggest that it may have formed a double bottom, which means it may bounce again until reaching its 50-day moving average. Thomas suggests investors to assume the dollar in a bear market with continued downward trends punctuated by short rallies. (Sector Highlight: U.S. dollar).

The Forex Market

The foreign exchange market, also known as the forex market, is the largest market in the world. In 2007, for example, it garnered $3.2 trillion worth of transactions each day. It’s the quiet giant of finance and dwarfs all other capital markets worldwide.

Unlike most other trading, such as futures, stocks or options, forex trading doesn’t happen on an exchange. It’s not controlled by any governing body, has no central exchange and there are no clearing houses involved guaranteeing trades. It’s a global network, made up of banks, corporations and individuals. The forex is also the most liquid market – there are always ready and willing buyers and sellers for the currency someone is seeking to trade.

The vast majority of currency trading is done bank-to-bank, and when each party enters into an agreement, they both take on the counterparty risk of the other. They’re not only competitors, but they’ve got to cooperate, as well.

There’s no actual buying and selling in the currency market – only trading, hence the need for cooperation.

Exchange traded funds (ETFs) have made entering this market much easier than it used to be. Prior to the launch of currency-related ETFs in 2005, the forex was a challenging market for individual investors to gain access to. Many investors might find this simplified access appealing, especially when you’re talking about a market that’s open 24 hours a day. If you’ve been eager to play this market, there are a rapidly growing number of opportunities to play the currency markets in the form of both ETFs and exchange traded notes (ETNs), which we’ll detail later.

Currency Basics

When entering the currency market, much of the focus is on the eight major currencies, which give you the best over- or under-valued opportunities. The eight major countries that make up the currency trading market are the United States, the Eurozone (Germany, France, Italy and Spain), Japan, United Kingdom, Switzerland, Australia, Canada and New Zealand.

There are many, many more currencies beyond the eight majors, such as the Brazilian real, Polish zloty and Hungarian forint.

Some of the key points to consider when you’re investing in currencies are:

• When trading currencies, yield drives return. Every currency has a yield.
• The forex allows huge leverage; often as high as 100:1 – which means that you can control $10,000 worth of assets with as little as $100 of capital. Remember, leverage works both ways, though.
• Since currency values never stay the same, the carry trade became a popular theory. Carry traders hope to earn not only the interest rate differential between the two currencies, but also look for their positions to appreciate in value. We’ll discuss this in more detail in the next section.
  
• Interest rates matter – a lot. Becoming familiar with the economics of the country in which the currency you are trading holds will help you understand when inflation is looming and when opportunity is knocking.

In currency markets, there’s always a bull somewhere. Why? The foreign exchange market is all about opposites and all about relativity. As one currency gains value, another has to be losing.

Dan McCabe, CEO at Next Investments, points out that one of the biggest advantages to investing in currencies is that it’s a great way to get non-U.S. dollar exposure.

“As an investor, I have nearly all my stuff in U.S. dollars. When I want to buy something, it’s often foreign-made. If I don’t have a hedge for the fact that the U.S. dollar may depreciate, I’m just losing my buying power on the world stage.”

For example, have a look at this five-year chart of the euro vs. the U.S. dollar. For the last three years, the euro steadily gained before falling off mid-way through 2008:

This means that as the euro gained strength, perhaps tourism in Europe suffered as Americans couldn’t afford to go over there and spend as much. But on the flip side, it likely brought tourists over here who were itching to spend and find bargains. Currency is all about relationships, and a currency being either weak or strong doesn’t necessarily mean it’s bad or good.

McCabe sees currencies as more of a buy-and-hold hedge instead of getting caught up in trading. “You’d rather just come in, buy it and put it away and look at it like a foreign money market account,” he says.

The Carry Trade

One of the most popular ways for institutional investors to play currencies is with the carry trade. Putting it simply, the carry trade involves borrowing currencies from countries with low interest rates and investing it in high interest rate countries. The strategy aims to take advantage of the wide spread in interest rates between certain currencies.

As of June 24, some interest rates for various currencies were:

• Australian Dollar, 3%
• New Zealand Dollar, 2.5%
• Euro, 1%
• U.S. Dollar, 0.25%
• Japanese Yen, 0.1%

You can track these interest rates at Daily FX.

With these interest rates in mind, an investor utilizing the carry trade would want to buy Australian dollars with the much lower-yielding Japanese yen, which is one of the most popular carry trade combinations around.

The carry trade isn’t a risk-free strategy, though. One of the biggest risks is if the exchange rate devalues by more than the average annual yield. If you’re using leverage, your losses could be even greater.

ETFs have simplified the carry trade for retail investors. The PowerShares DB G-10 Currency Harvest (DBV) tracks the interest rates of the U.S. dollar, euro, Japanese yen, Canadian dollar, Swiss franc, British pound, Australian dollar, New Zealand dollar, Norwegian krone and the Swedish krona. DBV looks at the three-month interest rates of the G10 currencies and goes long on the three with the highest rates and short on the three with the lowest. The ETF seeks to capitalize on the trend that the currencies with high interest rates generally tend to rise in value relative to currencies that have low interest rates.

Currency Risks

McCabe points out that currencies are non-correlated assets. “The risk you have oftentimes is performance vs. the underlying currency you’re purchasing in.”

As an example, assume that $1 equals 1 yen. If the dollar increases in value, you might get 1 yen for 90 cents – great if you’re traveling to Japan when this happens. However, it’s not so great if you have an asset priced in yen that you bought when dollars and yens were of equal value.

The flip side also works: if the dollar falls against various currencies, you stand to make money on assets based in those currencies if you bought them before the dollar weakened.

When searching for currencies to invest in, McCabe looks at the country behind it. Political upheaval can wreak havoc on a currency.

“I would look for a stable country with strong jurisprudence and rule of law…a country you believe is going to be stable, in case of turmoil.”

Why Use ETFs Instead?

Investing in currencies on your own, without an ETF, can be an arduous task. The currency market is one that never closes. Twenty-four hours a day, trillions and trillions of dollars in trades are taking place. You could find yourself sitting up in the middle of the night, waiting for a key signal to pounce on a trade.

That probably doesn’t sound like the average retail investor’s idea of a good time.

There are now two options for exchange traded currency investing: ETFs and exchange traded notes (ETNs).

Two key differences between currency ETFs and ETNs are:

1. Currency ETNs (like all ETNs) are backed by the full faith and credit of the issuer. If the issuer goes under, you have to get in line with all the other creditors. It’s a small risk, but it’s one to keep in mind.
2. Currency ETNs linked to a single currency are treated like debt for federal tax purposes, according to a 2007 IRS ruling. It means that any interest is taxable to investors, even though the interest is reinvested and not paid out until the ETN is sold or upon maturity of the contract. It also means that investors can’t elect capital gains treatment.

Not all exchange traded currency products are structured in the same way, either.

McCabe points out that it’s wise to be aware of what makes currency products different from one another. For example, Rydex’s CurrencyShares funds are grantor trusts – they hold the actual currency.

The interest earned on them is accrued on a daily basis and reinvested monthly. This reinvested interest is then reflected in the fund’s net asset value (NAV).

On the other hand, PowerShares‘ currency ETFs, PowerShares DB US Dollar Bullish Fund (UUP) and PowerShares DB US Dollar Bearish Fund (UDN), hold futures contracts and are registered as open-ended ETFs. Any gains from futures contracts are subject to 60/40 tax treatment, in which 60% of the gains are long-term, 40% are short-term.

In the bullish fund, the futures contracts are designed to be long on the U.S. dollar against the euro, yen, pound, canadian dollar, Swedish krona and Swiss franc. The bearish fund is designed to be short on the U.S. dollar against those currencies.

WisdomTree’s currency income ETFs invest in either non-U.S. moey market securities, or in a combination of money market instruments designed to provide exposure to non-U.S. money market securities or rates. They are not money market funds. They seek to give investors current income reflective of foreign money market rates available to U.S. investors, as well as exposure to changes in the value of a specific currency relative to the U.S. dollar.

Market Vectors‘ currency ETNs are senior, unsecured debt securities that give exposure to the exchange rate between U.S. dollars and foreign currencies. The underlying indexes are also affected by movements in interest rates in the country of the underlying currency and that of the United States’.

Market Vectors and ProShares also have some double long and double short ETNs for investors looking to enhance their exposure. They aim to double the daily performance of a specific currency. Know the risks of short and leveraged funds before you invest, however. They aren’t for everyone.

Barclays’ iPath currency ETNs measure the relative values of two currencies. In the EUR/USD fund, for example, when the euro rises against the U.S. dollar, the fund increases, and vice versa. The provider also has a currency carry ETN, iPath Optimized Currency Carry (ICI), that seeks to capture the returns potentially available from a carry trade. The pool of currencies the index may apply its strategies are known as the “G10″ currencies, which includes the U.S. dollar, euro, Japanese yen, Canadian dollar and Swiss franc.

How to Choose

At this point, there are enough ETNs and ETFs targeting currencies that investors have a whole range of choices when it comes to figuring out how they want to play them. When choosing currency ETFs, consider the differences between the available funds, how they access currencies and their tax treatment. In short, know what you own.

Perhaps one of the easiest ways is via a broad basket of currencies, which help spread out the risk and lessen the blows a volatile stock market can deliver. Some examples:

• Barclays Global Emerging Market Strategy [GEMS] Asia 8 Index ETN (AYT)
• Barclay’s iPath Optimized Currency Carry Exchange Traded Note (ICI)
• PowerShares DB G10 Currency Harvest Fund (DBV)
• WisdomTree Dreyfus Emerging Currency Fund (CEW)

It is clear that the emerging market is recovering faster than developed ones, according to ETF Grind. While developed markets are spurred by consumption, emerging markets are driven by investments. ETF Grind provides some funds that an investor may peruse so as to capitalize on the emerging markets over the next few years.

We should note, too, that there are many other ETFs that can provide similar exposure as the world decouples – this is merely a sampling:

DBV looks at the three-month interest rates of the G10 currencies and goes long on the three with the highest rates and short on the three with the lowest.

The ETF seeks to capitalize on the trend the currencies with high interest rates generally tend to rise in value relative to currencies that have low interest rates. DBV looks at the three-month interest rates of the G10 currencies and goes long on the three with the highest rates and short on the three with the lowest.

What’s Good

DBV gives investors a way to play the carry trade, which is gathering steam after a hiatus.

After developed economies reduced their interest rates to practically nothing, emerging markets with interest rates that are around 12.9% higher now look rather enticing, report Kim-Mai Cutler and Bo Nielsen for Bloomberg.

The Latest News

Goldman Sachs has begun recommending carry trades, which had been on their biggest losing streak in three decades. Thank stimulus plans and near-zero interest rates. In some emerging markets and commodity-rich nations, interest rates are as much as 12.9%, or even higher. From March 20 to April 10, the carry trade saw its biggest three-week gain since at least 1999.

How do currencies traders make a profit off “carry trades?” Well, traders use funds from countries with lower borrowing costs to invest in places with higher rates, and they would then reap in the differences in interest rates. Last year, this strategy was abandoned after volatility, as a result of the central bank policies of individual countries, led to large currency swings.

Typically, people would use dollar, euro and yen to buy up currencies from Brazil, Hungary, Indonesia, South Africa, New Zealand and Australia.

The Australian dollar, or “Aussie,” is forecast to fall 17% this year against the U.S. dollar and it is estimated that the Aussie will depreciate to 53 U.S. cents this year, writes Candice Zachariahs for Bloomberg. The weakening Aussie is a result of the Australian Reserve Bank cutting interest rates by 4% from September to February.

After a drop of 35% since hitting a 25-year high back in July, the Aussie may further depreciate as the country tackles its external debt that is around 89% of its GDP. It is thought that 34%, or $287 billion, of total external debt are in short-term loans.

In response to shrinking exports and increased pressure to further cut rates, the economy contracted 0.5% in the fourth quarter, a first in eight years. It is believed that the downward economic trend is likely to increase as a result of a long-reaching financial debacle.

Exports diminished by 5% with coal shipments down 19%. The trade surplus dropped to $624 million in January compared to earlier forecast of $704 million. It is predicted that there will be a $384 million deficit in 2009.
