Underpricing of Newly Issued Bonds: Evidence from the Swiss Capital Market

The pricing of newly issued bonds on the Swiss capital market is investigated over the years 1980–1982. The results reveal a slight underpricing of new bonds at the issue date that is roughly equal to the difference in transactions costs between the markets for new and seasoned bonds. Underpricing is no longer observed when the new bonds start to be traded on the stock exchange, that is, after about two days. Tests of several hypotheses show that unexpected changes in interest rates over the offering period explain part of the underpricing.     

Financial Markets' Views about the Euro–Swiss Franc Floor

Exchange rates and option prices incorporate market participants' views about the credibility and the effects of exchange rate targets. I present a model to determine exchange rates under policy targets that can be used to price options. The model is estimated with Euro–Swiss Franc exchange rate and options price data. In the first few months of the minimum exchange rate policy, the implied survival probability of the policy for a 3‐month horizon was typically less than 75%. Over time, the credibility increased and this probability reached 95% in August 2014.     

Do financial variables help predict the state of the business cycle in small open economies? Evidence from Switzerland

We analyze the forecasting ability of financial variables to predict the state of the Swiss business cycle up to eight quarters ahead. Overall, our results suggest that financial variables convey leading information for the prediction of business cycles, even when applied to a small open economy. However, we clearly find that model specifications need to be extended to include variables accounting for external shocks, such as exchange rates or international commodity prices. It also appears that the forecasting contribution of individual variables changes over time. Specifically, in the last two decades, stock market liquidity has replaced the term spread as the best single predictor.     

The analysis of foreign exchange data using waveform dictionaries

This paper uses waveform dictionaries to decompose the signals contained within three foreign exchange rates using tick-by-tick observations obtained world wide. The three exchange rates examined are the Japanese Yen and the German Deutsche Mark against the U.S. dollar and the Deutsche Mark against the Yen. The data were provided by Olsen Associates.A wabeform dictionary is a class of transforms that generalizes both windowed Fourier transforms and wavelets. Each waveform is parameterized by location, frequency, and scale. Such transforms can analyze signals that have highly localized structures in either time or frequency space as well as broad band structures; that is, waveforms can, in principle, detect everything from shocks represented by Dirac Delta functions, to short bursts of energy within a narrow band of frequencies, to the presence of frequencies that occur sporadically, and finally to the presence of frequencies that hold over the entire observed period. Waveform dictionaries are most useful in analyzing data that are not stationary and non-stationarity up to second order is well recognized in the context of foreign exchange rates.     

Bandwagon effects and run patterns in exchange rates

I analyze the monthly exchange rates of the US dollar against the pound sterling, the Japanese yen, and the Swiss franc. All three exchange rates show bandwagon patterns, changes in one direction tend to be followed by changes in the same direction. This regularity points towards the importance of momentum traders on foreign exchange markets. A recent experimental analysis suggests the following hypothesis regarding the dynamics of bandwagon effects: if there is a repetition of similar occurrences many agents expect this run to continue but reduce the perceived chances of further repetitions when they actually occur. For exchange rates this implies that a continuation of a change in one direction should become weaker if an exchange rate has shown repeated changes in the same direction in the immediate past. This conjecture is supported by the findings of this study.     

On the inadequacy of newswire reports for empirical research on foreign exchange interventions

Reuters news reports have become an accepted tool for empirical studies analyzing informational asymmetries in FX markets. This paper tests the accuracy of the Reuters reports for Swiss interventions in the foreign exchange market. The evidence finds that the time stamp of the Reuters reports does not always lie near the recorded time of the first intervention trade as is commonly assumed in market microstructure studies. The standard deviation of the time difference is measured in hours and not in minutes. These and other regression results question the accuracy of Reuters reports for Swiss interventions.     

Firm-level effects of asymmetric intervention in foreign exchange markets: Evidence from the Swiss currency floor

In January 2015, the Swiss National Bank (SNB) abandoned the Swiss franc's exchange rate floor against the Euro. This paper is the first to study the firm-level effects of this asymmetric type of central bank intervention in foreign exchange markets. Using weekly stock returns for a sample of Swiss non-financial firms, I find significant reductions in total stock return volatility as well as market risk following the introduction of the currency floor. Accounting for the asymmetric nature of the intervention, I show that the enforcement of this policy solely manifests in a significant reduction of incremental EUR/CHF exchange rate risk exposures of exporting firms, while importing firms experience reductions in proportion to the market portfolio only. Thus, the asymmetric policy design is reflected in asymmetric responses of firm-level currency exposures. All effects, however, do not depend on the extent of business activity in the Eurozone. The overall results suggest that the currency floor was successful in supporting the performance of the Swiss economy by effectively reducing stock return sensitivities to market fluctuations and EUR/CHF exchange rate volatility.     

The intraday multivariate structure of the Eurofutures markets

We investigate the multivariate intraday structure in interest rates, focusing on implied forward rates from Eurofutures contracts. Since futures markets are the most liquid for interest rate instruments and they yield high-quality intraday data, it is somehow surprising that their intraday behavior has not been thoroughly studied in the literature.We find interesting similarities with the foreign exchange market: scaling law, intraday patterns, all of which point to the heterogeneity of market participants. Other properties like asymmetric causal information flow between fine and coarse volatilities for the same time series are present in our data. There are also lead–lag correlations across the term structure of implied forward rates, but they tend to disappear as markets mature.A principal component analysis of the short end of the yield curve allows us to determine the most important components and to reduce the number of time series needed to describe the term structure. We find the decomposition rather stable over time. The first component, which describes the curve level, shows an asymmetry in the information flow between volatilities of different time resolution, i.e., the coarse-grained volatility predicts the fine-grained volatility better than the other way around, as observed in the foreign exchange market. The remaining components do not show such an effect, having instead significant negative autocorrelations for the time series themselves. A heterogeneous autoregressive conditional heteroskedasticity (HARCH) model is estimated for the first component and the impact of different market agents is discussed.     

Impact of interest rates on the life insurance market development: Cross-country evidence

Studies have found that interest rates create incentives for insurance firms to focus on financial markets through investments. Using a cross-country context, we conjecture that interest rates affect the life insurance market’s development. Using an initial sample comprising the time series of interest rates and insurance markets’ measures from 34 countries across 1998–2017, we found that the density and penetration of the life insurance market is low in countries with high interest rates. Using another sample of 6,451 observations from insurance firms operating in the same 34 countries, we verified that the financial and operational incomes are equally significant in predicting the net income for life insurance companies that operate in countries with high interest rates. Our study contributes to observations that the lack of governmental control over public expenses impacts interest rates and, thereby, the opportunities for insurers.     

The Forward Exchange Rate Bias Puzzle Is Persistent: Evidence from Stochastic and Nonparametric Cointegration Tests

An important puzzle in international finance is the failure of the forward exchange rate to be a rational forecast of the future spot rate. We document that even after accounting for nonstationarity, nonnormality, and heteroskedasticity using parametric and nonparametric tests on data for over a quarter century, U.S. dollar forward rates for the major currencies (the British pound, Japanese yen, Swiss franc, and the German mark) are generally not rational forecasts of future spot rates. These findings deepen the forward exchange rate bias puzzle, especially as these markets are the most liquid foreign exchange markets with very low trading costs.     

Efficiency in foreign exchange markets: A vector autoregression approach

This paper examines and tests the ‘simple efficiency’ property of the forward exchange market by analyzing the linearly indeterministic covariance stationary propertoes of the vector stochastic proceess that governs the joint behavior of the spot exchange rate and forward rates wiht different maturity dates. A multivariate autoregressive methodology for testing the ‘simple efficiency’ hypothesis that relies upon a set of highly non-linear cross-equation restrictions is utilized. The results of the estimation and testing for the British pound and the Deutsche mark over the period September 1974 to November 1987 using monthly observation on the spot rate, the one-month forward rate and the three-month forward rates are presented. Special concern is given to the sensitivity of the tests' results to subsampling over the period.     

Statistical study of foreign exchange rates, empirical evidence of a price change scaling law, and intraday analysis

In this paper we present a statistical analysis of four foreign exchange spot rates against the U.S. Dollar with several million intra-day prices over 3 years. The analysis also includes gold prices and samples of daily foreign exchange prices over 15 years. The mean absolute changes of logarithmic prices are found to follow a scaling law against the time interval on which they are measured. This empirical law holds although the distributions of the price changes strongly differ for different interval sizes.Systematic variations of the volatility are found even during business hours by an intra-day analysis of price changes. Seasonal heteroskedasticity is observed with a period of one day as well as one week as the result of an analogous intra-week analysis; taking this into account is necessary for any future study of intra-day price change distributions and their generating process. The same type of analysis is also made for the bid-ask spreads.     

New evidence on nominal exchange rate predictability

The Meese–Rogoff puzzle, one of the well-known puzzles in international economics, concerns the weak relationship between nominal exchange rates and market fundamentals. The purpose of this paper is to show that market fundamentals do in fact matter in forecasting nominal exchange rates. In particular, we emphasize the importance of the Harrod–Balassa–Samuelson effect in modeling deviations from purchasing power parity. Based on the post-Bretton Woods period, we provide solid out-of-sample evidence that rejects the random walk forecast model at medium-term and long-term forecast horizons. We also find mild evidence for out-of-sample predictability of nominal exchange rates over the short term.     

Cross-border spillover effects of unconventional monetary policies on Swiss asset prices

Unconventional monetary policies (UMPs) announced by the Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan exert important spillover effects on asset prices in Switzerland. Using a broad UMP event set and a long-term bond-futures based measure of market anticipation, we show that surprisingly expansionary UMPs lower Swiss government and corporate bond yields, induce the Swiss franc to appreciate, and dampen Swiss equity prices. Four extensions provide further insights. First, the estimated effects are strongest for announcements by the ECB. Second, the impact on government bonds is largest for bonds with residual maturities of 7–10 years. Third, the impact of foreign UMP shocks on exchange rates and Swiss bond yields is less pronounced after the introduction of the minimum rate of 1.20 Swiss franc per Euro by the Swiss National Bank on September 6, 2011, indicating that domestic monetary policy action partially affects the impact of external monetary shocks on domestic financial markets. Fourth, the sign of spillover effects differs for positive and negative UMP surprises, but their strength does not.     

Asymmetry in the effects of economic fundamentals on rising and falling exchange rates

Empirical research provides evidence for exchange rates overreaction to changes in economic fundamentals over a short run, but convergence in a long run. In this research we use statistical method developed by Cox [Cox, D.R., “Regression models and life-tables,” Journal of the Royal Statistical Society. Series B (Methodological), Vol. 34, Iss. 2 (1972), 187-220.] to examine the differences in the effects of local economic fundamentals on the probability of occurrence of extreme fluctuations in exchange rates over time periods of rising and falling exchange rates. We identify an extreme fluctuation as a 10% decrease or increase in exchange rate over a three month period and 20% over a one year period. We find asymmetry in the effects of economic fundamentals on exchange rates (eight countries' exchange rates quoted as f/$) during time periods of rising and falling exchange rates: the probability of extreme fluctuation is greater during time periods of rising exchange rates as compared to falling.     

The Stochastic Properties of Major Canadian Exchange Rates

This paper extends the results of Akgiray and Booth [2] on the stochastic properties of five major Canadian exchange rates using the EGARCH-M model along with the generalized error distribution (GED). In addition to the issue of first- and second-order dependencies, explored by the authors, the paper (1) addresses the issue of asymmetric volatility, (2) examines the extent to which volatility affects future movements in these exchange rates, (3) measures the amount of kurtosis in the data, and (4) investigates the transmission mechanism of innovations and volatility shocks across the five Canadian exchange rate markets. The five Canadian dollar exchange rates are for the U.S. dollar, the Japanese yen, the British pound, the German mark, and the French franc. Changes in Canadian exchange rates are conditionally heteroskedastic, a finding which is in line with that of Akgiray and Booth [2]. There is no evidence supporting the assertion that volatility triggers such changes. The hypothesis of asymmetric volatility is rejected for all Canadian exchange rates; thus unexpected appreciations and depreciations of the Canadian currency have similar impact on future volatility of these exchange rates. Innovations in the Canadian exchange rate markets for the U.S. dollar, the British pound, and French franc influence the Japanese yen market, while innovations in the markets of the British pound and German mark influence the French franc market. Significant but negative volatility spillovers radiate from the German mark market to the U.S. dollar market and from the French franc market to the German mark market, resulting in lower levels of volatility in both the U.S. and German markets. The distributions of all five series of Canadian exchange rates are highly leptokurtic relative to the normal distribution. The GED distribution provides a good characterization of these distributions.     

Heterogeneous time preferences and interest rates—the preferred habitat theory revisited

The influence of heterogeneous time preferences on the term structure is studied in the framework of a continuous-time pure exchange economy, in which agents have, apart from differential time preferences, the same degree of relative risk aversion. A closed-form solution for the financial equilibrium is obtained. In equilibrium, one long-term bond and one short-term bond form a complete market. Agents use these bonds to finance their consumption plans. The long-term bond is bought by agents with a long habitat. The short rate is a weighted average of the short rates which prevail in homogeneous economies populated by one type of agent only. It is shown by example that heterogeneity of time preferences can produce additional humps in the yield curve.     

A 10-year retrospective on the determinants of Russian stock returns

We study factors influencing returns at the Russian stock market from 1995 to 2004, putting emphasis on how these evolved over time. We find that the relationship is highly unstable and this instability is not confined to financial crises alone. Most computed statistics exhibit constant ups and downs, but there has been recently a sharp rise in explainability of stock returns. Domestic factors have been playing a gradually diminishing role, while the importance of international factors has been increasing. In recent years, the effect of oil prices and foreign exchange rates has diminished, the impact of US stock prices and international and domestic interest rates has increased, while the influence of monetary aggregates such as gold reserves and credit balances has fallen to practically zero.     

The term structure of the forward premium

Most studies of the efficiency of the foreign exchange market focus on a single maturity — usually a one month forward exchange rate. However, one observes that forward contracts of many maturities are simultaneously traded in the foreign exchange market. The hypothesis that the foreign exchange market uses all available information has implications for the joint behavior of forward exchange rates of various maturities. This paper proposes an equilibrium theory of the term structure of the forward premium. The model is tested using data on the German and Canadian exchange rates; the results indicate that the data are consistent with the theory for Germany and inconsistent with the theory for Canada.     

Causality-in-mean and causality-in-variance among electricity prices,crude oil prices,and yen–US dollar exchange rates in Japan

In this study, we test the Granger-causality-in-mean and Granger-causality-in-variance among electricity prices, crude oil prices, and yen-to-US-dollar exchange rates in Japan using a cross-correlation function approach. We find Granger-causality-in-mean from neither the exchange market nor the oil market to the power market; the same was true of Granger-causality-in-variance, although both the exchange rates and oil prices greatly influence power generation costs in Japan. We suspect the efficiency of this market is at play.
