Spillover and connectedness among G7 real estate investment trusts: The effects of investor sentiment and global factors

This paper examines the dynamic spillover interconnectedness of G7 Real Estate Investment Trusts (REITs) markets. We use the spillover index of Diebold and Yilmaz (2012), the time-varying parameters vector-autoregression (TVP-VAR) model, and the quantile regression approach. The result show that REITs network connectedness is dynamic and experiences an abrupt increase in the first wave of COVID-19 outbreak (2020Q1). We also observe a substantial abrupt decrease in connectedness during the success of vaccination programs (end 2021). The connectedness among assets is much stronger during COVID-19 than before. The REITs of Japan and Italy are net receivers of spillover and those of US and UK are net transmitters of spillovers before and during COVID-19. Conversely, the REIT of Canada and Germany (France) switches from net receivers (contributors) of spillovers before the pandemic to net contributors (receivers) during the COVID-19. Finally, we show that News Sentiment index, Geopolitical Risk index, Economic Policy Uncertainty index, US Treasury yield, and Stock Volatility index influence the spillover magnitude across quantiles. © 2023 Elsevier Inc.

Patterns of unconventional monetary policy spillovers during a systemic crisis

We examine whether the COVID-19 pandemic-induced systemic shocks cause a change in the dynamics of monetary policy spillovers among developed economies. Results from our analysis under the time-varying parameter vector autoregressive model indicate that: (i) variations in monetary policy actions are explained by monetary policy spillovers;(ii) shocks from the COVID-19 pandemic rocketed monetary policy spillovers;(iii) the Euro area and the US chiefly propagate monetary policy shocks to their counterpart developed economies;and (iv) New Zealand and Japan endure the highest monetary policy shocks. Our results evidence the need for synchronized monetary policy actions during systemic crises. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Impacts of COVID-19 on dynamic return and volatility spillovers between rare earth metals and renewable energy stock markets

We examine the time-frequency co-movements and return and volatility spillovers between the rare earths and six major renewable energy stocks. We employ the wavelet analysis and the spillover index methodology from January 1, 2018 to May 15, 2020. We report that the COVID-19-triggered significant increase in co-movements and spillovers in returns and volatility between the rare earths and renewable energy returns and volatility. The rare earths act as net recipient of both return and volatility spillovers, while the clean energy stocks are net transmitters of return and volatility spillovers before and during the COVID-19 crisis. The solar and wind stocks are net transmitters/receivers of spillovers before/during the pandemic. The remaining markets shift from net spillover receivers to transmitters or vice versa;evidencing the effects of the pandemic. Our results show that cross-market hedge strategies may have their efficiency impaired during the periods of crises implying a necessity of portfolio rebalancing. © 2022 The Authors

Flights-to-quality from EM Bonds to safe-haven US Treasury Securities: A time-frequency Analysis

We study 2001–2020 flight-to-quality episodes encompassing two planetary-scale crises: the Global Financial Crisis (GFC) of 2007–2008 and the coronavirus-triggered global meltdown. We focus on time-frequency lead-lag nexuses between holding emerging market (EM) debt and investing in relatively risk-free US Treasuries. Wavelet coherency along with the phase-difference approach is used. Our results reveal varying lead-lag patterns and low-coherence zones between EM bonds and US Treasuries, which imply the existence of appealing diversification attributes. The flights-to-quality during the crisis periods, such as the GFC and COVID-19 pandemic, emphasize the safe-haven characteristics of US Treasures. They also evidence that the post-Covid tightening of credit spreads to the pre-crisis levels is faster than the post-GFC recovery. We demonstrate that for EM debt investors, the US Treasury market allows for dynamic risk mitigation strategies during both global crises. © 2022 Taylor & Francis Group, LLC.
