Understanding Forward Premium in Currency Exchange

A forward premium occurs when the price of a currency in the future, known as the forward rate, is higher than its current spot price. This suggests that the domestic exchange rate is expected to strengthen against the foreign currency. Despite the intuitive expectation of a stronger currency, the terminology can be misleading because an increasing exchange rate signifies a depreciation in the currency’s value.

Key Points to Remember:

• A forward premium is when the expected future price of a currency exceeds its current spot price.
• The forward premium is often calculated as the difference between the current spot rate and the forward rate.
• If the forward premium is negative, it translates to a discount on the currency.

Decoding the Insights into Forward Premiums

The forward premium is commonly gauged by comparing the current spot rate with the potential forward rate. In practical terms, this comparison implies that the future spot rate may align with the current futures rate. According to the forward expectations theory, the present spot futures rate serves as a rough estimate for the future spot rate, supported by empirical evidence and long-term analysis.

Generally, a forward premium reflects changes influenced by interest rate differentials between the respective currencies of two countries involved in the currency exchange.

Forward exchange rates typically diverge from the spot rates. When the forward rate of a currency surpasses the spot rate, a premium exists, whereas a discount arises when the forward rate is lower than the spot rate.

Calculating Forward Rate Premiums

To determine a forward rate, you need the current spot price of the currency pair and the interest rates prevailing in the respective countries. For instance, consider a transaction involving the Japanese yen and the U.S. dollar:

• The 90-day yen to dollar (¥/$) forward exchange rate stands at 109.50.
• The spot rate for ¥/$ is 109.38.
• Calculating the annualized forward premium gives a result of 0.44%.

In this context, the U.S. dollar exhibits strength against the yen, with a premium of 0.12 yen per dollar. Conversely, the yen experiences a discount because its forward value concerning dollars is lower than its spot rate.

To determine the forward discount for the yen, you must calculate the forward and spot rates in terms of dollars per yen.

• The ¥/$ forward exchange rate is 0.0091324.
• The ¥/$ spot rate amounts to 0.0091424.
• An annualized forward discount for the yen is calculated at -0.44%.

For specific timeframes, like periods other than a year, adjustments based on the number of days are necessary. For example, a three-month forward rate calculation entails multiplying the spot rate by a given formula.

The forward rate is computed by multiplying the spot rate by the ratio of interest rates and considering the time remaining until maturity. To illustrate, if the current U.S. dollar-to-euro exchange rate is $1.1365, with U.S. and foreign interest rates at 5% and 4.75% respectively, applying the formula results in a forward premium.
