Leading up to last week's G8 summit in Japan, it was rumored that "volatility" in forex markets would be a hot topic of discussion. Thus, it came as quite a shock to analysts and investors that the final declaration failed to name any specific currencies. Politicians, especially those representing EU member states, seemed equally surprised. Many of them had hoped to at least come to a rhetorical consensus that the Euro was overvalued relative to the Dollar and Chinese Yuan, and perhaps also the Pound. Given that currencies are evidently not as much of a concern outside the EU, it seems unlikely that any kind of coordinated forex intervention will take place in the near-term. Bloomberg News reports:

The Carry Trade is one of the simplest strategies in forex, and if executed correctly, can also be one of the most profitable. The basic mechanics of a carry trade involve borrowing in one currency that offers a low interest rate, and selling it in favor of a higher-yielding currency, in order to capture the interest rate spread. This strategy carries two key risks. The first risk is that the "long" currency will depreciate. This also includes country risk, the possibility that political or macroeconomic instability will adversely affect the long currency. Then, there is the risk that the interest rate differential will change such that the spread shrinks, and a smaller carry is earned.

In a recent article for Seeking Alpha, financial journalist Ray Hendon offered an overview on the four principal strategies employed in the forex markets: carry trade, technical trade, fundamental trade, and arbitrage. The carry trade, which involves borrowing in a low-interest rate currency and buying a higher-yielding currency, can be undertaken by either buying ETF(s) or by trading directly using a retail forex account. The ETF route can be further subdivided into two possibilities: to buy a particular currency ETF to take advantage of the spread, or instead to buy one of two ETFs (symbols: ICI & DBV) that use computer models to mimic the carry trade.

WisdomTree and Dreyfus Funds recently unveiled five new currency ETFs in order to fill a broad gap in the emerging markets category. Previously, investors were limited to such mainstay currencies as the US Dollar, Euro, Japanese Yen, British Pound, Australian Dollar, Canadian Dollar, and Swiss Franc. These new ETFs will expand this list to include the Indian Rupee, Brazilian Real, and the much-anticipated Chinese Yuan. It will also offer products for the Euro and Yen, but these probably won't draw much attention. The RMB ETF, especially, will be pounced on by investors, who have been clamoring for years for a cheap and easy way to capture the upside of the Yuan's inevitable appreciation.
