In currency markets, carry trading is done by many investors to take benefit of the basic economic principle that money flows where the returns are high. This constant flowing in and out of capital between the different markets is what makes carry trading profitable.
Carry trading is one of the fundamental trading strategies employed by professional forex traders. Leveraged carry trading is one of the favorite strategies employed by hedge fund and investment banks. You as a forex trader can also benefit from carry trading.
Carry trading means taking benefit of the interest rate difference between two currencies. Carry traders take benefit of the interest rate differential between two currencies by buying or going long on the high interest rate currency and selling or going short on low interest rate currency.
Lets use a simple example to make it clearer: lets assume, New Zealand dollar is offering an interest rate of 4.75% whereas the Japanese yen is offering an interest rate of 0.25%.
In order to carry trade, an investor buys New Zealand dollars (NZD) and sells Japanese Yens (JPY). As long as the exchange rate between the NZD and JPY does not change, the investor will earn a profit of 4.75-0.25=4.5%. Using a leverage of 5:1, this 4.5% return will be leveraged into 22.5%.
Another thing that can go in favor of the investor is if the currency pair NZD/JPY appreciates, he/she can get capital appreciation as well as a yield. Many times, appreciation will also happen as many other investors also jump on the bandwagon when they see a good carry trading opportunity.
It depends a lot on the mood of the investors as a group. If investors as a group have low risk aversion, carry trading will be profitable. But if the investors as a group suddenly develops high risk aversion, carry trading will become unprofitable.
By entering into a carry trade, an investor expects to profit from an interest rate differential between the two currencies. But if the low interest rate currency appreciates considerably for some reason or another, carry trade will become unprofitable.
Before carry trading, it essential that you identify the current trend of the currency pair and see whether it is moving in the right direction!
MACD (moving average convergence divergence) indicator can help you in this regard. You should enter the trade when MACD crosses the zero line from below. You should exit the trade when it crosses the zero line from above.
