The formal theory of interest rate parity holds that under normal conditions the forward premium or discount on a currency in terms of another is directly related to the interest differential between the two countries. This theory holds only when there are unrestricted flows of international short-term capital. In reality, numerous economic and legal obstacles restrict the movement, so that actual parity is rare. See Interest Arbitrage.
