Book excerpt: We characterize the dynamics of the U.S. short-term interest rate using a Markov regime switching model. Using a test developed by Garcia (1998), we show that there are two regimes in the data: In one regime, the short rate behaves like a random walk with low volatility; in another regime, it exhibits strong mean reversion and high volatility. In our model, the sensitivity of interest rate volatility to the level of interest rate is much lower than what is commonly found in the literature. We also show that the findings of nonlinear drift in Ait-Sahalia (1996b) and Stanton (1997), using nonparametric methods, are consistent with our regime switching model.

Available in PDF, EPUB and Kindle. Book excerpt: Chan, Karolyi, Longstaff, and Sanders [1992] find no evidence that the October 1979 change in Federal Reserve operating policy resulted in a once-and-for-all deterministic break in the behavior of short term riskless interest rates. In contrast, we provide evidence of such a regime shift even after allowing the volatility of interest rate changes to depend on the level of interest rates. However, rather than modeling this regime shift as a permanent event with no further shifts possible, it is more realistic to model the change in regimes itself as a random variable. Accordingly, we put forward a stochastic volatility interest rate model which generalizes previous specifications of interest rate dynamics and allows testing for stochastic regime shifts. This Markov regime shifting model provides a more accurate description of the behavior of U.S. short term riskless interest rates. We also consider a specification that allows interest rate volatility to follow a diffusion process and we provide a statistically efficient integration-based filtering procedure to estimate its parameters. Given U.S. short term riskless interest rate data, we cannot statistically distinguish between these alternative models. In either case, once the stochastic nature of interest rate volatility is taken into account, we find little or no evidence of a deterministic structural break in corresponding stochastic volatility interest rate dynamics around October 1979.

Book excerpt: We develop a multivariate dynamic term structure model, which takes into account the nonlinear (time-varying) relationship between interest rates and the state of the economy. In contrast to the classical term structure literature, where nonlinearities are captured by increasing the number of latent state variables, or by latent regime shifts, in our no-arbitrage framework the regimes are governed by thresholds and are directly linked to economic fundamentals. Specifically, starting from a simple monetary policy model for the short rate, we introduce a parsimonious and tractable model for the yield curve, which takes into account the possibility of regime shifts in the behavior of the Federal Reserve. In our empirical analysis, we show the merit of our approach along the following dimensions: (i) interpretable bond dynamics; (ii) accurate short end yield curve pricing; (iii) yield curve implications.
Download or read book Modelling Yields at the Lower Bound Through Regime Shift written by Peter Hördahl and published by . This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The authors propose a regime-switching approach to deal with the lower bound on nominal interest rates in dynamic term structure modelling. In the "lower bound regime", the short term rate is expected to remain constant at levels close to the effective lower bound; in the "normal regime", the short rate interacts with other economic variables in a standard way. State-dependent regime switching probabilities ensure that the likelihood of being in the lower bound regime increases as short rates fall closer to zero. A key advantage of this approach is to capture the gradualism of the monetary policy normalization process following a lower bound episode. The possibility to return to the lower bound regime continues exerting an influence in the early phases of normalization, pulling expected future rates downwards. They apply our model to U.S. data and show that it captures key properties of yields at the lower bound. In spite of its heavier parameterization, the regime-switching model displays a competitive out-of-sample forecasting performance. It can also be used to gauge the risk of a return to the lower bound regime in the future. As of mid-2018, it provides a more benign assessment than alternative measures."--Abstract.
Download or read book Regime Shifts Risk and the Term Structure written by Martin D.D. Evans and published by . This book was released on 2010 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper develops and estimates a general equilibrium model for the term structures of nominal and real interest rates that incorporates regime-switching into the dynamics of the state variables. The model generates time-varying risk premia via changes in the covariance structure of the state variables and Peso problems through regime-switching. When the model is estimated using real and nominal yields from the U.K., I find that Peso problems emanating from instability in inflation have a significant impact on the nominal term structure. Peso problems affect (i) the sample predictability of excess returns, (ii) nominal term premia, and (iii) the inflation risk premia linking real and nominal yields with expected inflation.
Download or read book Exchange Rate Dynamics Intervention and Regime Shifts in China written by Wenting Zhang and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis applies the market microstructure approach to investigate exchange rate dynamics, intervention and regime shifts in China's exchange rate system. This research first examines exchange rate determination and dynamics from a microstructural perspective. An index of order flow is constructed in the Chinese context to reflect excess demand pressure. A VAR model is then estimated to explore to what extent order flow may explain long-term determination and short-term fluctuations of the renminbi exchange rate. Focusing on the cointegrating relationship between cumulative order flow and the exchange rate of the RMB against the US dollar, this research find that in the new Chinese exchange rate regime in place since 2005, order flow is able to explain a significant part of fluctuations in the RMB-dollar exchange rate. China is internationally noted for its intervention in the foreign exchange market. Based on high-frequency data this thesis adopt a multi-dimensional approach to explore how interventions are conducted in China, what the consequences are, and to what extent they are effective. This thesis identify evidence of China's extensive intervention and find that the authority is more likely to intervene to curb devaluation. Decomposition analysis shows that the direct impact of intervention on the exchange rate is more important than the impact via order flow. Intervention via the central bank's involvement in trading is effective in influencing both the exchange rate and order flow, but tends to increase volatility. Intervention by the central bank's varying the central parity condition plays some role in 'leaning against the wind', but cannot reverse the trend. China announced the reform of its exchange rate system in 2005. The reform was disrupted by the breakout of the global financial crisis around 2008, but was reiterated in 2010. The thesis analyses the behaviour of China's exchange rate policy since then. This research detect 21st June 2010 as the date of regime shift, since when the RMB has been allowed greater room for flexibility, and consequently exchange rate volatility has increased. This research unearths evidence confirming that the renminbi no longer pegs only to the dollar. During the crisis period, deviations from the central parity rate (CPR) increase the possibility of government intervention, and the intervention correlates with bid-ask exchange rate spread. The Chinese monetary authority is found to act to keep the exchange rate stable. In the post-crisis period, the correlation becomes time-varying and the government prefers the RMB exchange rate to gradually appreciate. This research finds evidence that appreciation of the RMB exchange rate is order flow driven during the post-crisis period. There is a significant negative currency exposure during the financial crisis, caused by changes in the RMB exchange rate, indicating that the Chinese stock market exhibits a negative reaction in the period. However, no significant impact is found in the post- crisis period. In order to modify the exchange rate exposure to fluctuations of the US dollar, the Chinese government seems to have adopted the relatively more efficient exchange rate regime to handle the effects of the global financial crisis.

Book excerpt: We estimate forward-looking interest rate rules for five large Organization for Economic Cooperation and Development economies, allowing for time variation in the responses to macroeconomic conditions and in the variance of the policy rate. Conventional constant parameter reaction functions likely blur the impact of (1) model uncertainty, (2) conflicting objectives, (3) shifting preferences, and (4) nonlinearities of policymakers' choices. We find that monetary policies followed by the United States, the United Kingdom, Germany, France, and Italy are best summarized by feedback rules that allow for time variation in their parameters. Estimates point to sizeable differences in the actual conduct of monetary policies even in countries now belonging to the European Monetary Union. Moreover, our time-varying parameter specification outperforms the conventional Taylor rule and generalized method of moment-based estimates of reaction functions in tracking the actual Fed funds rate.

Download or read book Yield Factor Volatility Models written by Christophe Perignon and published by . This book was released on 2013 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term structure of interest rates is often summarized using a handful of yield factors that capture shifts in the shape of the yield curve. In this paper, we develop a comprehensive model for volatility dynamics in the level, slope, and curvature of the yield curve that simultaneously includes level and GARCH effects along with regime shifts. We show that the level of the short rate is useful in modeling the volatility of the three yield factors and that there are significant GARCH effects present even after including a level effect. Further, we find that allowing for regime shifts in the factor volatilities dramatically improves the model's fit and strengthens the level effect. We also show that a regime-switching model with level and GARCH effects provides the best out-of-sample forecasting performance of yield volatility. We argue that the auxiliary models often used to estimate term structure models with simulation-based estimation techniques should be consistent with the main features of the yield curve that are identified by our model.

Download or read book Hidden Markov Models in Finance written by Rogemar S. Mamon and published by Springer. This book was released on 2014-05-14 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the groundbreaking research of Harry Markowitz into the application of operations research to the optimization of investment portfolios, finance has been one of the most important areas of application of operations research. The use of hidden Markov models (HMMs) has become one of the hottest areas of research for such applications to finance. This handbook offers systemic applications of different methodologies that have been used for decision making solutions to the financial problems of global markets. As the follow-up to the authors’ Hidden Markov Models in Finance (2007), this offers the latest research developments and applications of HMMs to finance and other related fields. Amongst the fields of quantitative finance and actuarial science that will be covered are: interest rate theory, fixed-income instruments, currency market, annuity and insurance policies with option-embedded features, investment strategies, commodity markets, energy, high-frequency trading, credit risk, numerical algorithms, financial econometrics and operational risk. Hidden Markov Models in Finance: Further Developments and Applications, Volume II presents recent applications and case studies in finance and showcases the formulation of emerging potential applications of new research over the book’s 11 chapters. This will benefit not only researchers in financial modeling, but also others in fields such as engineering, the physical sciences and social sciences. Ultimately the handbook should prove to be a valuable resource to dynamic researchers interested in taking full advantage of the power and versatility of HMMs in accurately and efficiently capturing many of the processes in the financial market.
Download or read book Dynamic Asset Pricing Theory written by Darrell Duffie and published by Princeton University Press. This book was released on 2010-01-27 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a thoroughly updated edition of Dynamic Asset Pricing Theory, the standard text for doctoral students and researchers on the theory of asset pricing and portfolio selection in multiperiod settings under uncertainty. The asset pricing results are based on the three increasingly restrictive assumptions: absence of arbitrage, single-agent optimality, and equilibrium. These results are unified with two key concepts, state prices and martingales. Technicalities are given relatively little emphasis, so as to draw connections between these concepts and to make plain the similarities between discrete and continuous-time models. Readers will be particularly intrigued by this latest edition's most significant new feature: a chapter on corporate securities that offers alternative approaches to the valuation of corporate debt. Also, while much of the continuous-time portion of the theory is based on Brownian motion, this third edition introduces jumps--for example, those associated with Poisson arrivals--in order to accommodate surprise events such as bond defaults. Applications include term-structure models, derivative valuation, and hedging methods. Numerical methods covered include Monte Carlo simulation and finite-difference solutions for partial differential equations. Each chapter provides extensive problem exercises and notes to the literature. A system of appendixes reviews the necessary mathematical concepts. And references have been updated throughout. With this new edition, Dynamic Asset Pricing Theory remains at the head of the field.
