Spillovers, integration and causality in LME non-ferrous metal markets
No full textWe examine the interrelationships in the global base metal markets over a 22 year period 1994–2016 using a variety of econometric methods. The results demonstrate the high intensity of both return and volatility spillovers across the selected markets. Furthermore, the degree of co-movements varies among time and frequencies. The study also contributes to the contagion literature since the results revealed the increase in co-movements after the financial crisis. Aluminium is found to be the driving force, with significant influence across all methodologies. The findings show that the behaviour of the non-ferrous metals is similar to other conventional asset classes, like equities and bonds, justifying the position that metals have become an investment class
Bitcoin-energy markets interrelationships - New evidence
Full text linkThe annual electricity consumption of cryptocurrency transactions has grown substantially in recent years, partially driven by the increasing difficulty in mining, but also driven by the large number of new market participants that have been attracted by the elevated prices of this developing financial asset. Total carbon production from mining now likely exceeds that generated by individual developed nations. This is now a prevailing and accepted feature in cryptocurrency markets, however unsustainable it may be. This paper investigates as to how Bitcoin’s price volatility and the underlying dynamics of cryptocurrency mining characteristics affect underlying energy markets and utilities companies. Further analysis of potential side-effects within the market for Exchange Traded Funds are considered. The results show a sustained and significant influence ofcryptocurrency energy-usage on the performance of some companies in the energy sector as separated by jurisdiction, emphasising the importance of further assessment of environmental impacts of cryptocurrency growth. Robustness testing presents evidence that dynamic correlations peaked during the sharp Bitcoin price appreciation of late-2017 as investors re-evaluated how this increased energy usage would influence the profitability of utility companies
Determinants of cryptocurrency returns: A LASSO quantile regression approach
No full textWe consider a relatively large set of predictors and investigate the determinants of cryptocurrency returns at different quantiles. Our analysis exclusively focuses on the highly volatile period of COVID-19. The innovation in the paper stems from the fact that we employ the LASSO penalty in a quantile regression framework to select informative variables. We find that US government bond indices and small company stock returns, a new predictor introduce in this study, significantly impact the tail behavior of the cryptocurrency returns
Systemic risk contagion of green and Islamic markets with conventional markets
No full textFinancial markets are exposed to extreme uncertain circumstances escalating their tail risk. Sustainable, religious, and conventional markets represent three different markets with various characteristics. Motivated with this, the current study measures the tail connectedness between sustainable, religious, and conventional investments by employing a neural network quantile regression approach from December 1, 2008 to May 10, 2021. The neural network recognized religious and conventional investments with maximum exposure to tail risk following the crisis periods reflecting strong diversification benefits of sustainable assets. The Systematic Network Risk Index spots Global Financial Crisis, European Debt Crisis, and COVID-19 pandemic as intensive events yielding high tail risk. The Systematic Fragility Index ranks the stock market in the pre-COVID period and Islamic stocks during the COVID sample as the most susceptible markets. Conversely, the Systematic Hazard Index nominates Islamic stocks as the chief risk contributor in the system. Given these, we portray various implications for policymakers, regulatory bodies, investors, financial market participants, and portfolio managers to diversify their risk using sustainable/green investments
KODAKCoin: a blockchain revolution or exploiting a potential cryptocurrency bubble?
Full text linkEastman Kodak is an American technology company that produces imaging products. In 2018, it announced its intentions to enter the crytpocurrency market, raising concerns that it could be taking advantage of a potential cryptocurrency bubble for short-term gains. We analyse the relationships between Kodak, crytocurrency and stock market index returns. We find evidence of a significant, sustained increase in both the share price and price volatility of Kodak after the KODAKCoin announcement, with an increased correlation between the price of Kodak shares and Bitcoin
The relationship between implied volatility and cryptocurrency returns
No full textWe analyse the relationship between the price volatility of a broad range of cryptocurrencies and that of implied volatility of both United States and European financial markets as measured by the VIX and VSTOXX respectively. Overall, our results indicate the existence of time-varying positive interrelationships between the conditional correlations of cryptocurrencies and financial market stress. Further, these correlations are found to increase substantially during periods of high financial market stress, indicating that the contagion of significant financial market fear influences these new financial product
Cryptocurrency reaction to FOMC announcements: Evidence of heterogeneity based on blockchain stack position
Full text linkWe examine the response of a broad set of digital assets to US Federal Fund interest rate and quantitative easing announcements, specifically examining associated volatility spillover and feedback effects. We classify each digital asset into one of three categories: Currencies; Protocols; and Decentralised Applications (dApps). Currency-based digital assets experience idiosyncratic spillovers in the period immediately after US monetary policy announcements, while application or protocol-based digital assets are largely immune to policy volatility spillover and feedback. Mineable digital assets are found to be more susceptible to monetary policy volatility spillovers and feedback than non-mineable. Responses indicate a diverse market within which, not all assets are comparable to Bitcoin
The impact of macroeconomic news on Bitcoin returns
No full textThis paper examines the relationship between news coverage and Bitcoin returns. Previous studies have provided evidence to suggest that macroeconomic news affects stock returns, commodity prices and interest rates. We construct a sentiment index based on news stories that follow the announcements of four macroeconomic indicators: GDP, unemployment, Consumer Price Index (CPI) and durable goods. By controlling for a number of potential biases we determine as to whether each of the series' have a significant impact on Bitcoin returns. While an increase in positive news surrounding unemployment rates and durable goods would typically result in a corresponding increase in equity returns, we observe the opposite to be true in the case of Bitcoin. Increases in positive news after unemployment and durable goods announcements result in a decrease in Bitcoin returns. Conversely, an increase in the percentage of negative news surrounding these announcements is linked with an increase in Bitcoin returns. News relating to GDP and CPI are found not to have any statistically significant relationships with Bitcoin returns. Our results indicate that this developing cryptocurrency market is further maturing through interactions with macroeconomic new
Datestamping the Bitcoin and Ethereum bubbles
Full text linkWe examine the existence and dates of pricing bubbles in Bitcoin and Ethereum, two popular cryptocurrencies using the (Phillips et al., 2011) methodology. In contrast to previous papers, we examine the fundamental drivers of the price. Having derived ratios that are economically and computationally sensible, we use these variables to detect and datestamp bubbles. Our conclusion is that there are periods of clear bubble behaviour, with Bitcoin now almost certainly in a bubble phase
COVID-induced sentiment and the intraday volatility spillovers between energy and other ETFs
No full textDid Covid19 induce market turmoil and impact the intraday volatility spillovers between energy and other ETFs? To examine this, we first estimate the realized volatility of ETFs using the 5-minute high-frequency data. Next, we employ time-varying parameter vector autoregressions (TVP-VAR). Finally, we utilize the wavelet coherence measure to test the time-frequency impact of COVID-induced sentiment on the spillovers by employing investors’ psychological and behavioural factors. We find that oil and stock markets are net transmitters while currency, bonds, and silver markets are net receivers. The wavelet analysis embarked significant impact of media coverage and fake news index towards shaping investors’ pessimism for their investments. We proposed useful implications for policymakers, governments, investors, and portfolio managers
