Academic literature on the topic 'Theory of interest rate parity'

Estimation of the actual and projected level of the neutral interest rate is a central issue in the application of modern monetary theory in the practical context of monetary policy. Views on the role and key drivers of neutral interest rates have evolved over time in parallel with the development of the theory of capital, money, credit and economic growth. Therefore, the paper is aimed at generalizing methods for assessing the neutral interest rate for open economies with emerging markets and formulating recommendations for improving the existing methodological tools for estimating the neutral rate in Ukraine. To achieve this goal, theoretical sources, advisory and research materials of international organizations, central banks and statistical databases were analyzed. It is established that the key issue of the current discussion about the tools for estimating the level of neutral interest rates in countries with small open economies is the relationship between the effects of external and internal factors. The paper identifies the advantages and disadvantages of the method for estimating the level of the neutral rate on the basis of uncovered interest parity rule used by the National Bank of Ukraine within the semi-structural macroeconomic model. The expediency of methodological tools introducing into the practice of monetary regulation of Ukraine for estimating the neutral rate of Ukraine based on the Laubach-Williams approach has been proved with adaptation to the conditions of an open economy, which will consider сinternal factors of economic development – changes in potential GDP and savings.

The study examines the impact of interest rate differential and exchange rate movement on the dynamics of Nigeria’s international private capital flows from 2010Q1 to 2019Q4. It uses the interest rate parity theory and the Markov Switching Time Varying Transition Probability Modelling approach. Findings show that interest rate differential does not explain the dynamics of aggregate capital and Foreign Direct Investment (FDI) flows, but significantly explains Foreign Portfolio Investment (FPI) flows. Also, Movement in real exchange rate is significant in explaining outflows and inflows in FPI, and inflows in FDI, but neutral to aggregate capital flows. The study concludes that deviations from interest rate parity provides opportunities for interest rate and currency arbitrage in Nigeria but using aggregate capital flows mask this evidence. The study therefore recommends that the CBN should focus on exchange rate stabilization policies, so as not only to discourage FPI reversal but to also enhance FDI inflow. This can be done by putting in place foreign reserve accretion measures to boost the ability of the CBN to defend the Naira. The new policy initiative on remittances is a right step in the right direction as it could boost external reserve.

We present a new identity that relates expected exchange rate appreciation to a risk-neutral covariance term, and use it to motivate a currency forecasting variable based on the prices of quanto index contracts. We show via panel regressions that the quanto forecast variable is an economically and statistically significant predictor of currency appreciation and of excess returns on currency trades. Out of sample, the quanto variable outperforms predictions based on uncovered interest parity, on purchasing power parity, and on a random walk as a forecaster of differential (dollar-neutral) currency appreciation.
