## What is interest rate parity?

Interest rate parity (IRP) is a theory according to which the interest rate differential between two countries is equal to the differential between the forward exchange rate and the spot exchange rate.

How do you calculate interest parity?

Interest rate parity formula

1. ST(a/b) = The Spot Rate.
2. St(a/b) = Expected Spot Rate at time T.
3. Ft(a/b) = The Forward Rate.
4. T = Time to Expiration Date.
5. ia = Interest Rate of Country A.
6. ib = Interest Rate of Country B.

How does interest rate parity work?

Interest Rate Parity (IRP) is a theory in which the differential between the interest rates of two countries remains equal to the differential calculated by using the forward exchange rate and the spot exchange rate techniques. Interest rate parity connects interest, spot exchange, and foreign exchange rates.

### Does interest rate parity exist?

Interest rate parity is a theory proposing a relationship between the interest rates of two given currencies and the spot and forward exchange rates between the currencies. Covered interest rate parity exists when forward contract rates of currencies can be used to prove that no arbitrage opportunities exist.

What is PPP formula?

Purchasing power parity = Cost of good X in currency 1 / Cost of good X in currency 2. A popular practice is to calculate the purchasing power parity of a country w.r.t. The US and as such the formula can also be modified by dividing the cost of good X in currency 1 by the cost of the same good in the US dollar.

Why is it called covered interest rate parity?

The covered interest rate parity condition says that the relationship between interest rates and spot and forward currency values of two countries are in equilibrium. Covered and uncovered interest rate parity are the same when forward and expected spot rates are the same.

#### What is interest rate parity with example?

As an example, assume Country X’s currency is trading at par with Country Z’s currency, but the annual interest rate in Country X is 6% and the interest rate in country Z is 3%. Covered interest rate parity exists when the forward rate of converting X to Z eradicates all the profit from the transaction.

### How is interest rate parity related to covered arbitrage?

•As a result of market forces, the forward rate differs from the spot rate by an amount that sufficiently offsets the interest rate differential between two currencies. •Then, covered interest arbitrage is no longer feasible, and the equilibrium state achieved is referred to as interest rate parity(IRP). 7. 18 Derivation of IRP

When to use uncovered interest rate parity ( IRP )?

Uncovered Interest Rate Parity (IRP) The IRP is said to be covered when the no-arbitrage condition could be satisfied through the use of forward contracts in an attempt to hedge against foreign exchange risk.

When does parity hold in foreign exchange markets?
