Parity

Parity is a term that is used in a variety of financial contexts. In its most basic sense, parity refers to the equality of two values. For example, if the exchange rate between the U.S. dollar and the euro is 1:1, then the two currencies are said to be at parity.

In the context of the foreign exchange market, parity is often used to refer to the theoretical exchange rate between two currencies that would result in the purchasing power of each currency being equal. For example, if the price of a Big Mac in the United States is $5 and the price of a Big Mac in Europe is €5, then the exchange rate between the dollar and the euro would be 1:1.

Parity can also be used to refer to the equality of two prices for the same commodity in different markets. For example, if the price of oil is $100 per barrel in the United States and €100 per barrel in Europe, then the two markets are said to be at parity.

In the context of the stock market, parity is often used to refer to the price of a stock relative to its book value. For example, if a stock is trading at a price of $100 and its book value is $10, then the stock is said to be trading at a parity of 10:1.

Parity can also be used to refer to the equality of two interest rates. For example, if the interest rate on a one-year Treasury bill is 2% and the interest rate on a one-year certificate of deposit is 2.5%, then the two rates are said to be at parity.

In general, parity is a term that is used to describe the equality of two values. In the context of finance, parity can be used to refer to the equality of two prices, two interest rates, or two exchange rates.
