Pros and cons of carry trades
During periods of low volatility in forex markets, carry trades can work out very well for investors. They can borrow money at an extremely low cost and put the money in any type of asset they expect to perform well. That could be a conservative investment, such as Treasuries, for a guaranteed return. Or, it could be high-growth investments, such as exchange-traded funds (ETFs) or individual stocks.
The biggest risk is a change in the market conditions and, in turn, the exchange rate for the currencies you're using. Imagine you borrow yen to trade with U.S. dollars. If the yen rises in value during your trade, you're going to need more dollars to pay back what you borrowed.
