Spillovers between sovereign CDS and exchange rate markets: The role of market fear

As important variables in financial market, sovereign credit default swaps (CDS) and exchange rate have correlations and spillovers. And the volatility spillovers between the two markets become further complicated with the effect of market fear caused by extreme events such as global pandemic. This paper attempts to explore the complex interactions within the “sovereign CDS-exchange rate” system by adopting the forecast error variance decomposition method. The results show that there is a relatively close linkage between the two markets and the total spillover index of the system is dynamic. For most of the past, the exchange rate has a higher spillover effect on the sovereign CDS than vice versa. Moreover, after the market fear variables are introduced, the “sovereign CDS-exchange rate” system and market fear variables present bidirectional spillovers. The results of the study have particular significance for maintaining the financial stability and preventing risk contagion between markets.     

Real exchange rate behaviour: evidence from black markets

The behaviour of real exchange rates (relative to the US dollar) is examined using monthly data obtained from the black markets for foreign exchange of eight Asian developing countries. The data span is 31 years. The black market real exchange rates do not show excess volatility during the recent float which is in sharp contrast to the results reported elsewhere. Unit root tests in heterogeneous panels and variance ratio tests confirm their stationarity. Thus, we find support for PPP but not for the ‘survivorship’ bias (Froot and Rogoff, 1995 ). There is little evidence of segmented trends. Issues raised by Rogoff ( 1996 )—of whether PPP would hold across countries with differing growth experience—and Lothian and Taylor ( 1996 )—of whether the degree of relative price volatility may bias results in favour of mean reverting real exchange rates—are addressed.

Interest rate dynamics and volatility transmission in the European short term interest rate market

This paper investigates the price and volatility relationship in European short-term interest rate markets. Cointegration analysis is used to analyse the long and short run relationship and a GARCH BEKK model is estimated to analyse the volatility transmission between the markets. The stability of the long run relationship is also examined using Bai and Perron (Econometrica 66(1),47–78, 1998, J Appl Econ 18(1):1–22, 2003) structural break methodology. The results show that the relationship between the EURIBOR spot deposit rate and the EURIBOR future contract has changed significantly since 2001 and several structural breaks are present in the 13 year sample period. During periods where there is a long run relationship present the spot deposit rate generally leads the future rate in price discovery. In the short run there is bi-directional causality present between the markets. There is also significant evidence of volatility transmission from the spot market to the futures market throughout the sample period.     

Stocks,bonds, money markets and exchange rates: measuring international financial transmission

Understanding the complexity of the financial transmission process across various assets—domestically as well as within and across asset classes—requires the simultaneous modeling of the various transmission channels in a single, comprehensive empirical framework. The paper estimates the financial transmission between money, bond and equity markets and exchange rates within and between the USA and the euro area. We find that asset prices react strongest to other domestic asset price shocks, but that there are also substantial international spillovers, both within and across asset classes. The results underline the dominance of US markets as the main driver of global financial markets: US financial markets explain, on average, around 30% of movements in euro area financial markets, whereas euro area markets account only for about 6% of US asset price changes. Moreover, the methodology allows us to identify indirect spillovers through other asset prices, which are found to increase substantially the international transmission of shocks within asset classes.

Low interest rate policy and the use of reserve requirements in emerging markets

This paper sheds light on the link between the interest rate policy in large advanced economies with international funding and reserve currencies (the United States and the euro area) and the use of reserve requirements in emerging markets. Using reserve requirement data for 28 emerging markets from 1998 to 2012, we provide evidence that emerging market central banks tend to raise reserve requirements when interest rates in international funding markets decline or financial inflows accelerate, most likely to preserve financial stability. In contrast, when global liquidity risk rises and funding from the large advanced economies dries up, emerging markets lower reserve requirements.     

The relative size of exchange rate and interest rate responses to news: An empirical investigation

This paper examines the relative size of the effects of macroeconomic news on the spot exchange rate, and interest rate differentials (2- and 5-year swap rate differentials), and the synthetic forward exchange rate schedule, for the high-frequency New Zealand data. We find that the spot exchange rate and 5-year swap rates respond by a similar magnitude to monetary surprises, implying there is little response of the forward exchange rate to this type of news. In contrast, the spot exchange rate responds by nearly three times as much as 5-year interest rates to CPI and GDP surprises, implying that forward rates appreciate to higher than expected CPI or GDP news. This is in contrast to standard theoretical models and US evidence. Lastly, we show that exchange rates but not interest rates respond to current account news. The implications of these results for monetary policy are considered.     

Non-linear,hybrid exchange rate modeling and trading profitability in the foreign exchange market

A neuro-fuzzy decision-making technology is designed and implemented to obtain the optimal daily currency trading rule. It is found that a non-linear, artificial neural network exchange rate microstructure (hybrid) model combined with a fuzzy logic controller generates a set of trading strategies that earn a higher rate of return compared to the simple buy-and-hold strategy. After accounting for realistic transaction costs, the gains from utilizing a dynamic, neuro-fuzzy model are still present.     

Foreign exchange interventions and interest rate policy in the Czech Republic: Hand in glove?

This paper studies the impact of daily official FX interventions on the Czech koruna's exchange rate vis-à-vis the euro (the German mark) from 1997 to 2002. Both the event study methodology extended with official interest rate moves and a variety of GARCH models reveal that FX interventions, especially koruna purchases, were relatively ineffective from 1997 to mid-1998. From mid-1998 to 2002, however, koruna sales turned out to be effective in smoothing the path of the exchange rate for up to 60 days. Nevertheless, the event study approach also indicates that the success of FX interventions depends crucially on the coordination of intervention and interest rate policies.     

Detecting contagion in Asian exchange rate markets using asymmetric DCC-GARCH and R-vine copulas

This study uses asymmetric DCC-GARCH models and copula functions to study exchange rate contagion in a group of twelve Asia-Pacific countries. Using daily data between November 1991 and March 2017, we show that extreme market movements are mainly associated with the high degree of interdependence registered by countries in this region. Evidence of contagion is scarce. Asymmetries do not appear to be important. Specifically, currency co-movements are statistically identical during times of extreme market appreciation and depreciation, indicating that phenomena such as the fear of “appreciation” do not appear to be relevant in the region’s foreign exchange markets.

A multivariate GARCH in mean approach to testing uncovered interest parity: evidence from Asia-Pacific foreign exchange markets

The existence of time-varying risk premia in deviations from uncovered interest parity (UIP) is investigated based on a conditional capital asset pricing model (CAPM) using data from four Asia-Pacific foreign exchange markets. A parsimonious multivariate generalized autoregressive conditional heteroskedasticity in mean (GARCH-M) parameterization is employed to model the conditional covariance matrix of excess returns. The empirical results indicate that when each currency is estimated separately with an univariate GARCH-M parameterization, no evidence of time-varying risk premia is found except Malaysian ringgit. However, when all currencies are estimated simultaneously with the multivariate GARCH-M parameterization, strong evidence of time-varying risk premia is detected. As a result, the evidence supports the idea that deviations from UIP are due to a risk premium and not to irrationality among market participants. In addition, the empirical evidence found in this study points out that simply modeling the conditional second moments is not sufficient enough to explain the dynamics of the risk premia. A time-varying price of risk is still needed in addition to the conditional volatility. Finally, significant asymmetric world market volatility shocks are found in Asia-Pacific foreign exchange markets.     

Dependent relationships between Chinese commodity markets and the international financial market: Evidence from quantile time-frequency analysis

In this article, the quantile time–frequency method is utilized to study the dependence of Chinese commodities on the international financial market. The impacts of risk management and diversification benefits of different portfolios are examined by calculating the reduction in downside risk. Moreover, we estimate and compare Sharpe Ratios (SRs) and Generalized Sharpe Ratios (GSRs) based on the frequencies of the investigated portfolios. Our empirical results reveal a strong asymmetric response from Chinese commodity markets. Specifically, we find that gold is a safe-haven asset, and due to negative correlations found at lower quantiles in medium and long term, an increase in the USD index damages bull commodity markets but boosts bear conditions under long-term investments, and negative (positive) tail correlations with interest rates (IRs) in bull (bear) markets are observed. It is proven that WTI can decrease short-run risks while USD and GOLD are more efficient in the diversification of downside risk. Adding international commodities may not improve the returns of Chinese commodities at given risk levels in the short and medium term through SRs and GSRs. In brief, investors should consider these dependence structures and modes of risk management in terms of time and frequency.     

Analysis of asymmetric response of exchange rate to interest rate differentials: The case of African Big 4

Using the case of four leading African economies, namely Algeria, Egypt, Nigeria and South Africa, this paper explores the possibility of asymmetric relationship between exchange rate and interest rate differential. In addition, it also tests whether accounting for structural breaks matters for the nexus. The results vary for the four countries based on the choice of exchange rate regime and countries involved in full-fledged floating or managed floating seem to respond more to variations in interest rate differential. Also, accounting for both asymmetries and structural breaks should not be disregarded when modelling this nexus.     

The international volunteering market: market segments and competitive relations

• The number of nonprofit and social agencies relying on the help of volunteers has grown enormously in recent decades. This has lead to increased competition between these organisations for the limited resources available, and the growing adoption of what have traditionally been considered ‘commercial’ business techniques such as marketing. There have been calls for greater and more sophisticated use of ‘tried and tested’ marketing concepts such as competition, segmentation and positioning to help volunteering organisations manage this pressure effectively. This study shines the spotlight on individuals who volunteer for multiple types of organisations in an effort to determine which organisations are competing for the same volunteers. More specifically:
• Factor analyses are computed and four segments of volunteers are identified: ‘altruists’, ‘leisure volunteers’, ‘political volunteers’ and ‘church volunteers’;
• Positioning maps are constructed to illustrate the proximity of each organisation type in relation to key competitors; and
• Detailed profiles are provided for each segment to provide insight into the nature of the groupings.

The credibility of the Colombian exchange rate target zone: Its impact over the volatility of interest rate differentials

This paper analyzes the credibility of Colombia’s exchange rate target zone, and in particular its impact on the volatility of interest rate differentials. Bertola and Caballeros’ (1995) model of a target zone with imperfect credibility is used to derive the impact of a reduction in credibility over the variance of the interest rate differential. It is theoretically shown, that as credibility decreases the variance of the interest rate differential increases. This theoretical argument is used to estimate credibility in Colombia’s exchange rate target zone. Using a SWARCH model, the probability of being in a regime with high interest rate volatility is estimated, and is related with events in the exchange rate market. Results suggest that there is evidence of lack of credibility even before the recent international financial turmoil was triggered.     

Dependence structures between Chinese stock markets and the international financial market: Evidence from a wavelet-based quantile regression approach

In this study, we investigate the dependence structures between six Chinese stock markets and the international financial market including possible safe haven assets and global economic factors under different market conditions and investment horizons. The research is conducted by combining a quantile regression approach with a wavelet decomposition analysis. Although we find little or insignificant dependence under short investment horizons, we detect the strong asymmetric dependence of oil prices and the US dollar index on the six Chinese stock markets in the medium and long terms. Moreover, not only is crude oil not a safe haven, it may damage Chinese stock markets as it increases over the long term, even in bull markets. Meanwhile, appreciation of the US dollar (depreciation of RMB) damages (boosts) Chinese stock markets during bull (bear) market conditions under long investment horizons. Moreover, we find that VIX (volatility index)-related derivatives may serve as good risk management tools under any market condition, while gold is a safe haven asset only during crisis periods.     

Exchange rate regimes and market integration: evidence from the dynamic relations between renminbi onshore and offshore markets

The Chinese renminbi (RMB) has been on the way of becoming a major international currency. This paper examines the impact of the RMB exchange rate regime and policy on the integration and information flows between RMB onshore and offshore markets. We employ a long sample of daily data encompassing multiple times of RMB exchange rate regime change (peg to managed float in 2005, re-peg in 2008, re-float in 2010, and the central parity reform in 2015), and study the dynamic conditional correlations and spillovers between RMB onshore spot market and offshore non-deliverable forward (NDF) market. It is found that the switch from exchange rate peg to managed float and a widening of the floating band strengthen cross-market correlation and information flows (especially offshore-to-onshore spillovers). A market-learning explanation is offered for the observation that the correlation collapse in the re-peg period was not as prompt as the correlation take-off in the 2005 reform period. These findings have important implications for China’s monetary and foreign exchange policies and shed light on the integration of China’s financial markets with the rest of the world.     

Black market exchange rate,currency substitution and the demand for money in LDCs

Mundell's conjecture in 1963 that the demand for money could depend on the exchange rate in addition to income and interest rate has received some attention in the literature by including the official exchange rate and estimating the money demand in a few developed countries. In less developed countries, since there is a black market for foreign exchange, it has been suggested that the black market exchange rate rather than the official rate should be the determinant of the demand for money in LDCs. This proposition is tested by estimating the demand for money for 25 LDCs using the bounds testing approach to cointegration. The main conclusion is that while in some LDCs, the black market rate enters into the formulation of the demand for money, in some others the official rate is the determinant. The black market premium also played a role in some countries.     

Bond market co-movements,expected inflation and the GBP-USD equilibrium real exchange rate

Since the end of the fixed rates in 1973 and after the European Monetary System (EMS) sterling dismissal in 1992, the value of the pound has undergone large cyclical fluctuations on average. Of particular interest to policy makers is the understanding of whether such movements are consistent with the lack or not of a correction mechanism to some long-run equilibrium. The purpose of the present study is to understand those dynamics, how the external value of the British sterling (GBP) relative to the US dollar (USD) evolved during the recent floating experiences, and what have been the driving forces. In this paper we assume the real exchange rate to be determined by forces relating to the goods and capital market in a general equilibrium framework. This entails testing the purchasing power parity (PPP) and the uncovered interest parity (UIP) together. In doing so, we model inflation expectations explicitly. Our findings have two important implications, both for monetary policy. First, we show that some of the observed changes in the bilateral real exchange rate cannot be solely attributed to changes in inflation rates, but, also to capital markets. Secondly, we find a weaker behavior of the US bond rate on international markets, possibly explained by the special US dollar status of World reserve currency.     

The relationship between oil prices,the stock market and the exchange rate: Evidence from Mexico

This paper analyzes the variables of oil price, exchange rate and stock market index to explain how they interact with each other in the Mexican economy. The examined period includes monthly data from January 1992 to June 2017. A Vector Autoregressive Model (VAR) is implemented that includes oil prices, the nominal exchange rate, the Mexican stock market index, and the consumer price index. Results indicate that the exchange rate has a negative and statistically significant effect on the stock market index; this indicates that an appreciation of the exchange rate is related to an increase in the stock market index. It is also found that the consumer price index has a positive effect on the exchange rate and a negative effect on the stock market index. The results also indicate that oil prices are statistically significant against the exchange rate, concluding that an increase in oil prices creates an appreciation of the exchange rate. In addition, the impulse-response functions show that the effects found tend to disappear over time.
