The carry trade opportunity was also seen in USD/JPY in 2005. Between January and December of that year, the currency rallied from 102 to a high of 121.40 before ending at 117.80. This is equal to an appreciation from low to high of 19%, which was far more attractive than the 2.9% return in the S&P 500 during that same year. In addition, at the time, the interest rate spread between the U.S. dollar and the Japanese yen averaged around 3.25%. Unleveraged, this means that a trader could have earned as much as 22.25% over the course of the year. Introduce 10:1 leverage, and that could be as much as 220% gain.
Margin and leverage are among the most important concepts to understand when trading forex. These essential tools allow forex traders to control trading positions that are substantially greater in size than would be the case without the use of these tools. At the most fundamental level, margin is the amount of money in a trader's account that is required as a deposit in order to open and maintain a leveraged trading position.
In forex, investors use leverage to profit from the fluctuations in exchange rates between two different countries. The leverage that is achievable in the forex market is one of the highest that investors can obtain. Leverage is activated through a loan that is provided to an investor by the broker that is handling the investor’s or trader’s forex account.
