Risk spillover between cryptocurrencies and traditional currencies: An analysis based on neural network quantile regression
The burgeoning prominence of cryptocurrencies within the global financial landscape necessitates a reevaluation of their interplay with conventional currencies. This paper employs a neural network quantile regression (NNQR) framework to delineate a risk spillover network encompassing nine cryptocurrencies and eleven traditional currencies. Our findings suggest that cryptocurrencies are less affected by traditional currencies during systemic crises such as the COVID-19 pandemic, despite the escalation of system-wide risk. Cryptocurrency exposures also come mainly within their markets during special times, which exhibits a significant degree of autonomy. This autonomy positions them as potential short-term hedges against policy-induced risks. Furthermore, our study also finds that cryptocurrencies have less betweenness centrality compared to traditional currencies, but their closeness centrality is not much different from traditional currencies. Our research identifies the Canadian dollar and the Indian rupee as being notably vulnerable to risk spillovers emanating from the cryptocurrency sector. However, there are significant differences in the traditional currencies that have a considerable impact on different cryptocurrencies. This study offers novel perspectives for investors considering the utilization of cryptocurrencies for out-of-market risk hedging strategies.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
