Volatility Linkages Among Gold Futures in Emerging Markets

We aim to detect the cross-border volatility linkages among gold futures in emerging markets, which still remain an untapped area. China, India, Japan, Taiwan, Turkey, and U.S. futures markets are included in the sample. The volatility linkage analyses confirm the existence of volatility transmission among the majority of the sample countries’ gold futures. This article carries vital inferences and implications for policy makers and investors. The policy making is particularly important for China, which is a relatively isolated market. From investors’ perspective, the results indicate that the risk diversification and cross-market hedging opportunities in the emerging gold futures markets are quite limited.     

Financing the green projects: Market efficiency and volatility persistence of green versus conventional bonds,and the comparative effects of health and financial crises

The establishment of the green bond market is an attempt to attain environmental sustainability from the finance perspective. One of the factors that could either hinder or promote this course is the degree of market efficiency of the market. Against this background, this study comparatively examines the market efficiency of the U.S. green and conventional bonds. In addition, the performance of both markets is investigated during global health and financial crises. Applying the fractional integration technique, we find that the overall green and conventional bonds markets are still inefficient, indicating that green and conventional investors can make excess gains by predicting the future trends of bond prices. There is also evidence that the green bond market exhibits higher volatility persistence during the global health crisis than during the global financial crisis. These findings are corroborated by the GARCH-based models, whose results show that volatility shocks are more persistent in the green bond market during the health crisis than during the financial crisis. However, the conventional bond market observes persistence in volatility shocks during both events. Towards sustainable environment goals, these results have relevant implications for green investors and policy makers.     

Brand equity of stock exchange as a mediator in financial decisions

The aim of this study is to investigate investors’ brand equity perception for a stock exchange as a mediator in financial investment decisions. An online survey is conducted in two samples in the developed market context of Ireland and developing one of Turkey. Results indicate that although investors’ risk perception has a negative impact on investment decisions, this impact is partially mediated by brand equity of stock exchanges in question. This mediating effect further differs by the market context, with a larger effect size in the developing Turkish market. It can be concluded that although developing markets face higher volatility in macroeconomic conditions, it could be possible to spread the risk resulting from this volatility with an effective brand equity management, which is found to be especially important in developing markets. The study offers some practical implications to policy makers and managerial sides regarding the need for a careful perception management aimed at individual investors.     

Intra- and inter-regional return and volatility spillovers across emerging and developed markets: Evidence from stock indices and stock index futures

We provide empirical evidence on the patterns of intra- and inter-regional transmission of information across 10 developed and 11 emerging markets in Asia, the Americas, Europe and Africa using both stock indices and stock index futures. The main transmission channels are examined in the period from 2005 to 2014 through the analysis of return and volatility spillovers around the most recent crises based on the generalized vector autoregressive framework. Our findings demonstrate that markets are more susceptible to domestic and region-specific volatility shocks than to inter-regional contagion. A novel result reported in our study is a difference in patterns of international signals transmission between models employing indices and futures data. We conclude that futures data provide more efficient channels of information transmission because the magnitude of return and volatility spillovers across futures is larger than across indices. Our findings are relevant to practitioners, such as stock market investors, as well as policy makers and can help enhance their understanding of financial markets interconnectedness.     

Volatility spillovers across NFTs news attention and financial markets

The aim of this study is to investigate the volatility spillover connectedness between NFTs attention and financial markets. This paper firstly proposes a new direct proxy for the public’s attention in the NFT market: the non-fungible tokens attention index (NFTsAI), based on 590m news stories from the LexisNexis News & Business database and applies the historical decomposition to assess the historical variations of the NFTsAI. Then the empirical analysis is performed via a TVP-VAR volatility spillover connectedness model. The empirical results show that NFTsAI indicates NFT markets are dominated by cryptocurrency, DeFi, equity, bond, commodity, F.X. and gold markets. And NFT markets are volatility spillover receivers. In addition, NFT assets could impede financial contagion and have significant diversification benefits. Employing a panel pooled OLS regression model as a supplementary analysis and a GARCH-MIDAS model as a robustness test. This study reveals that NFTsAI has sufficient power to explain the return of NFT assets from a fixed effect perspective, and NFTsAI contains useful forecasting information for both short and long-term volatility of NFT markets, separately. The new NFTsAI and the empirical findings contain useful insights for risk-averse investors, portfolio managers, institutional investors, academics and financial policy regulators.     

The “forward premium puzzle” and the sovereign default risk

Carry-trade strategies which consist of buying forward high-yield currencies tend to yield positive excess returns when global financial markets are booming, whereas they generate losses during crises. Firstly, we show that the sovereign default risk, which is taken on by investing in high-yield currencies, may increase the magnitude of the gains during the boom periods and the losses during crises. We empirically test for this hypothesis on a sample of 18 emerging currencies over the period from June 2005 to September 2010, the default risk being proxied by the sovereign credit default swap spread. Relying on smooth transition regression (STR) models, we show that default risk contributes to the carry-trade gains during booms, and worsens the losses during busts. Secondly, we turn to the “Fama regression” linking the exchange-rate depreciation to the interest-rate differential. We propose a nonlinear estimation of this equation, explaining the puzzling evolution of its coefficient by the change in the market volatility along the financial cycle. Then, we introduce the default risk into this equation and show that the “forward bias”, usually evidenced by a coefficient smaller than unity in this regression, is somewhat alleviated, as the default risk is significant to explain the exchange-rate change.     

Information in the Term Structure of Yield Curve Volatility

Using a novel no‐arbitrage model and extensive second‐moment data, we decompose conditional volatility of U.S. Treasury yields into volatilities of short‐rate expectations and term premia. Short‐rate expectations become more volatile than premia before recessions and during asset market distress. Correlation between shocks to premia and shocks to short‐rate expectations is close to zero on average and varies with the monetary policy stance. While Treasuries are nearly unexposed to variance shocks, investors pay a premium for hedging variance risk with derivatives. We illustrate the dynamics of the yield volatility components during and after the financial crisis.     

Dynamic relations of uncertainty expectations: a conditional assessment of implied volatility indices

This study examines the spillover effects in international financial markets with respect to implied volatility indices. The use of the latter as the basis of integration analysis means that we test market participants’ expectations and not the actual price fluctuations. The empirical analysis, which includes all publicly available implied volatility indices, employs the dynamic conditional correlation model of Engle (2002) and its findings suggest that there is significant integration of investors’ expectations about future uncertainty. Furthermore, by accounting for the dynamic volatility of implied volatility inter-dependencies, we are able to reveal possible shifts in conditional correlations of market expectations over time. More specifically, our findings show a slight increase in the conditional correlations for all the volatility indices under review over the years and prove that in periods of turbulence in the financial markets the conditional correlations across implied volatility indices increase.     

Does gold Liquidity learn from the greenback or the equity?

This study seeks to understand and elucidate shifts of gold, dollar, and stock market liquidity, both before and after the 2008 financial crisis. The relationship among these assets is examined by allowing for nonlinear dynamics in the speed of adjustment to the equilibrium. The findings document the predictability role of liquidity proxies of dollar and equity on gold liquidity even after accounting for macroeconomic variables, suggesting that liquidity of both assets maintains an influence on gold behavior. During periods of high exchange-rate volatility between currencies, gold liquidity becomes highly affected by dollar liquidity movements through a nonlinear smooth transition framework. Yet evidence reveals that to fully understand the movements of gold and dollar it is necessary to factor in stock market liquidity as well.     

The calming effects of conflict: The impact of partisan conflict on market volatility

In recent decades, an increasing divide in political ideologies between Republicans and Democrats has had a notable impact on financial markets. In this paper, we investigate the effect of political conflict, as measured by the partisan conflict index (PCI), on both market and industry-level volatility. We find that PCI has a significant negative impact on market volatility, robust to different regression models. We provide evidence that such impact is not driven by dramatic political events, namely wars and presidential elections, or by presidential party. When controlling for market cycles, we show that PCI reduces volatility during expansionary periods but increases volatility during recessions. Furthermore, at the industry level, we find that PCI decreases volatility overall. We also find that PCI decreases the volatility of politically-sensitive industries significantly more that it does with other industries. These results can inform government policy makers, analysts, investors, and academics alike.     

Illiquidity and volatility spillover effects in equity markets during and after the global financial crisis: An MEM approach

Even though the volatility spillover effects in global equity markets have been documented extensively, the transmission of illiquidity across national borders has not. In this paper, we propose a multiplicative error model (MEM) for the dynamics of illiquidity. We empirically study the illiquidity and volatility spillover effects in eight developed equity markets during and after the recent financial crisis. We find that equity markets are interdependent, both in terms of volatility and illiquidity. Most markets show an increase in volatility and illiquidity spillover effects during the crisis. Furthermore, we find volatility and illiquidity transmission are highly relevant. Illiquidity is a more important channel than volatility in propagating the shocks in equity markets. Our results show an overall crucial role for illiquidity in US markets in influencing other equity markets' illiquidity and volatility. These findings are of importance for policy makers as well as institutional and private investors.     

The impact of foreign equity flows on market volatility during politically tranquil and turbulent times: The Egyptian experience

Since the popular uprising of January 2011, a series of momentous events has rocked Egypt’s political order, jeopardising the country’s economic and financial stability. This study examines the role of foreign capital flows in the volatility of the Egyptian equity market, and whether this role has changed due to the recent domestic political unrest. These issues are empirically addressed in the context of GMM estimation. The results suggest that, unlike those of foreign individual investors, trades of foreign institutional investors contribute to market fluctuations, whether prior to or following the January 2011 uprising. Sell trades by foreign individual and institutional investors exert a significant influence on volatility. Further, when volume is split into its anticipated and unanticipated components, the results show that surprises in trading activity by either group tend to exacerbate volatility in periods of calm and turmoil. These findings are broadly insensitive to volatility measures and robust, even after controlling for a variety of relevant determinants of market volatility. The evidence documented in this study provides important implications for policy markers.     

Economic evaluation of asymmetric and price range information in gold and general financial markets

Gold is widely perceived as a good diversification or safe haven tool for general financial markets, especially in market turmoil. To fully understand the potential, this study constructs an asymmetric multivariate range-based volatility model to investigate the dependence and volatility structures of gold, stock, and bond markets and further to compare the difference between the financial crisis and post-financial crisis periods. We find a striking explanatory ability to volatility structures provided by the price range information and significant evidence of asymmetric dependence across gold, stock, and bond markets. We implement an asset-allocation strategy incorporating asymmetric dependence and price range information to explore their economic importance. The out-of-sample results show that between 35 and 517 basis points and between 90 and 1111 basis points are earned annually when acknowledging asymmetric dependence and price range information, respectively. These economic benefits are inversely related to the level of investors’ risk aversion and are particularly significant in the period of the global financial crisis.     

The time-varying asymmetry of exchange rate returns: A stochastic volatility – stochastic skewness model

While the time-varying volatility of financial returns has been extensively modelled, most existing stochastic volatility models either assume a constant degree of return shock asymmetry or impose symmetric model innovations. However, accounting for time-varying asymmetry as a measure of crash risk is important for both investors and policy makers. This paper extends a standard stochastic volatility model to allow for time-varying skewness of the return innovations. We estimate the model by extensions of traditional Markov Chain Monte Carlo (MCMC) methods for stochastic volatility models. When applying this model to the returns of four major exchange rates, skewness is found to vary substantially over time. In addition, stochastic skewness can help to improve forecasts of risk measures. Finally, the results support a potential link between carry trading and crash risk.     

Ethical and unethical investments under extreme market conditions

This study investigates the time-varying volatility and risk measures of ethical and unethical investments. We apply the Bayesian Markov-switching generalized autoregressive conditional heteroscedasticity (MS-GARCH) approach to compute the value-at-risk (VaR) and expected shortfall (ES) of ethical and unethical indices returns, which allows for detecting the differences between ethical and unethical investments. The innovative finding of our study is that ethical investments are less affected during global financial crises compared with unethical and conventional investments. The policy implication of this study is that investors should consider ethical investments as a hedging asset for their portfolios during extreme market conditions.     

Comparative analysis on the effects of the Asian and global financial crises on precious metal markets

The global financial crisis has vigorously struck major financial markets around the world, in particular in the developed economies since they have suffered the most. However, some commodity markets, and in particular the precious metal markets, seem to be unscathed by this financial downturn. This paper investigates therefore the nature of volatility spillovers between precious metal returns over fifteen years (1995-2010 period) with the attention being focused on these markets’ behavior during the Asian and the global financial crises. Daily closing values for precious metals are analyzed. In particular, the variables under study are the US$/Troy ounce for gold, the London Free Market Platinum price in US$/Troy ounce, the London Free Market Palladium price in US$/Troy once, and the Zurich silver price in US$/kg. The main sample is divided into a number of sub periods, prior to, during and after the Asian crisis. The aim of this division is to provide a wide and deep analysis of the behavior of precious metal markets during this financial event and of how these markets have reacted during times of market instability. In addition, this paper also looks at the effects of the global financial crisis from August 2007 to November 2010 using GARCH and EGARCH modeling. The main results show that there is clear evidence of volatility persistence between precious metal returns, a characteristic that is shared with financial market behavior as it has been demonstrated extensively by the existing literature in the area. In terms of volatility spillover effects, the main findings evidence volatility spillovers running in a bidirectional way during the periods; markets are not affected by the crises, with the exception of gold, that tends to generate effects in all other metal markets. However, there is little evidence in the case of the other precious metals generating any kind of influence on the gold market. On the other hand, there is little evidence of spillover effects during the two crisis episodes. Finally, the results from asymmetric spillover effects show that negative news/information have a stronger impact in these markets than positive news, again a characteristic that has been also exhibited by financial markets.     

Lessons from the Tequila Crisis

This paper draws several important lessons from the Tequila Crisis of 1994 and 1995. The overriding lesson is that the dynamics of financial crises in emerging market countries differ from those in industrialized countries because institutional features of their debt markets differ. Several policy lessons for emerging market countries also emerge from the analysis: (1) pegged exchange-rate regimes are extremely dangerous, (2) strong prudential supervision of the banking system is critical for prevention of financial crises, (3) financial liberalization must be managed extremely carefully and (4) different policies are needed to promote recovery in emerging market countries than those that are applicable to industrialized countries.     

The euro exchange rate during the European sovereign debt crisis – Dancing to its own tune?

This paper studies the determinants of the euro exchange rate volatility during the European sovereign debt crisis, allowing a role for macroeconomic fundamentals, policy actions and the public debate by policy makers. It finds that the euro exchange rate mainly danced to its own tune, with a particularly low explanatory power for macroeconomic fundamentals. The findings of the paper also suggest that financial markets might have been less reactive to the public debate by policy makers than previously feared. Still, there are instances where exchange rate volatility increased in response to news, such as on days when several politicians from AAA-rated countries went public with negative statements, suggesting that communication by policy makers at times of crisis should be cautious about triggering undesirable financial market reactions.     

Does gold glitter in the long-run? Gold as a hedge and safe haven across time and investment horizon

During times of market turmoil, investors often seek to mitigate risks associated with traditional investment assets such as equities and debt. The hedging and safe-haven properties of gold are examined in this paper for investors with short- and long-run horizons. Utilizing wavelet analysis, we find that gold acts as a hedge for a variety of international equity and debt markets for horizons of up to one year. The safe haven properties of gold during financial crises are further established, with gold shown to act as a safe haven for equity investors for long-run horizons of up to one year. However, during the economic contractions of the early 1980s gold is found not to act as a safe haven, displaying a positive relationship with equities across a range of horizons.     

Investor information and bank instability during the European debt crisis

Outside of financial crises, investors have little incentive to produce private information on banks’ short-term liabilities held as information-insensitive safe assets. The same does not hold during crises. We compare the information effects of different policy interventions. We measure information production using credit default swap spreads during the Global Financial Crisis and the European debt crisis. We study abnormal information production around major events and find that capital injections reduced abnormal information production while early European stress tests increased it. High levels of information production predict bank balance sheet contraction and higher government expenditures to support financial institutions.
