What is a carry trade? 

Copy link to section

A carry trade is a trading strategy that involves borrowing at a low-interest rate and investing in an asset that provides a higher rate of return. Carry trading is most commonly undertaken when investing in forex markets.

The foreign exchange market (forex) is a global market where world currencies are traded for each other, in the form of currency pairs like EUR/USD or GBP/USD. The forex market is responsible for setting foreign exchange rates for every currency in the world. Traders use forex brokers to either buy or sell different currencies, with the goal of making a profit if the currency they’re trading moves in the direction they’ve predicted.
