How is the nominal exchange rate defined?
The nominal exchange rate is the price of a base currency in terms of the quote currency.
What is the formula for the log excess return of a zero-cost strategy that borrows in USD and invests in foreign currency?
The log excess return of a zero-cost strategy that borrows in USD and invests in foreign currency is given by: $$r_e^{t+1} = s_{t+1} - s_t + i^*_t,t+1 - i_t,t+1$$
What does covered interest rate parity (CIP) imply?
Covered interest rate parity (CIP) implies that the forward rate equals the spot rate adjusted for the interest rate differential between two currencies.
How can you calculate the forward rate using CIP?
Using CIP, the forward rate can be calculated as: $$f_{t,T} = s_t + i_t,T - i^*_t,T$$
What is uncovered interest rate parity (UIP)?
Uncovered interest rate parity (UIP) states that the expected return from investing in USD and the foreign currency should be the same, implying that the expected change in the nominal exchange rate should exactly compensate for any difference in interest rates.
Does UIP hold in practice? Explain why or why not.
UIP does not hold in practice because currencies with high interest rates tend to appreciate rather than depreciate, contrary to UIP predictions.
What is the regression model used to evaluate UIP?
The regression model used to evaluate UIP is: $$s_{t+1} - s_t = \alpha + \beta (i_t,t+1 - i^*_t,t+1) + \epsilon_{t+1}$$
What are common risk factors in currency markets according to Lustig, Roussanov, and Verdelhan (2011)?
Common risk factors in currency markets include country-specific and global risk factors that determine interest rates and exchange rates. Exposure to the global factor should be priced.
What is the HML FX portfolio?

What is the carry trade strategy?
The carry trade strategy involves going short in low-interest rate currencies and long in high-interest rate currencies.
What are the most popular currencies for the carry trade?
The most popular currencies for the carry trade are CHF, JPY (short), and NZD, AUD, NOK, and emerging markets currencies (long).
What is the downside risk associated with the carry trade?
The downside risk associated with the carry trade includes the potential for significant losses during market crashes, as high interest rate currencies tend to earn high risk premia due to their heavy load on downside risk.
How do global imbalances affect currency returns?
Global imbalances affect currency returns as countries with external foreign-currency net debt have to compensate investors with higher average returns as their currencies depreciate in bad times.
What is FX momentum?
FX momentum refers to the tendency of past winners to outperform in the near future.
