Currencies

A currency rate involves the price of the base currency (e.g., the dollar) quoted in terms of another currency (e.g., the yen), or in terms of a basket of currencies (e.g., the dollar index). The world’s major currencies have traded in a floating-rate exchange rate regime ever since the Bretton-Woods international payments system broke down in 1971 when President Nixon broke the dollar’s peg to gold. The two key factors affecting a currency’s value are central bank monetary policy and the trade balance. An easy monetary policy (low interest rates) is bearish for a currency because the central bank is aggressively pumping new currency reserves into the marketplace and because foreign investors are not attracted to the low interest rate returns available in the country. By contrast, a tight monetary policy (high interest rates) is bullish for a currency because of the tight supply of new currency reserves and attractive interest rate returns for foreign investors.

The other key factor driving currency values is the nation’s current account balance. A current account surplus is bullish for a currency due to the net inflow of the currency, while a current account deficit is bearish for a currency due to the net outflow of the currency. Currency values are also affected by economic growth and investment opportunities in the country. A country with a strong economy and lucrative investment opportunities will typically have a strong currency because global companies and investors want to buy into that country’s investment opportunities. Futures on major currencies and on cross-currency rates are traded primarily at the Chicago Mercantile Exchange.
