What is CIP and UIP?

The difference between UIP and the CIP is that CIP is based on the assumption that the forward market is used to cover against exchange risk. Foreign exchange transactions are conducted simultaneously in the current market and forward markets. Whereas in UIP, there is not any covers against exchange risk.

What is PPP and IRP?

The IRP theory is based on the notion that high interest rates are driven by high inflation rates (see the PPP above), so a comparatively high interest rate would signal a comparatively high level of inflation.

What is the main difference between covered and uncovered interest?

Covered interest parity involves using forward contracts to cover the exchange rate. Meanwhile, uncovered interest rate parity involves forecasting rates and not covering exposure to foreign exchange risk—that is, there are no forward rate contracts, and it uses only the expected spot rate.

What is UIP condition?

The textbook uncovered interest parity (UIP) condition states that the expected change in the exchange rate between two countries over time should be equal to the interest rate differential at that horizon.

What is UIP finance?

Uncovered interest rate parity (UIP) theory states that the difference in interest rates between two countries will equal the relative change in currency foreign exchange rates over the same period. It is one form of interest rate parity (IRP) used alongside covered interest rate parity.

How do you test UIP?

One common method to test for UIP is by running regression on a CIP model and testing the hypothesis for the constant to be zero and the coefficient on the interest differential to be 1. Majority of studies done on UIP find that it does not hold. The expected value as well as the sign of the coefficient has been wrong.

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 covered interest parity should hold?

CIRP holds that the difference in interest rates should equal the forward and spot exchange rates. Without interest rate parity, it would be very easy for banks and investors to exploit differences in currency rates and make loose profits.

What will happen if IRP does not hold?

The situation where IRP does not hold would allow for the use of an arbitrage. If the actual forward exchange rate is higher than the IRP forward exchange rate, then you could make an arbitrage profit.

Does the UIP hold?

UIP is very different from CIP. It involves exchange risk and speculation. In reality, UIP may or may not hold due to the existence of this uncertainty. Indeed, the bulk of empirical evidence suggests that it usually does not hold.
