What is carry?

Carry is the most popular trade in the currency market, practiced by both the largest hedge funds and the smallest retail speculators. The carry trade rests on the fact that every currency in the world has an interest rate attached to it. These short-term interest rates are set by the central banks of these countries: the Federal Reserve in the U.S., the Bank of Japan in Japan and the Bank of England in the U.K. (To learn more, see What Are Central Banks?)
