COVID-19 and the liquidity network

Area of Science:

• Financial Economics
• Network Analysis
• Pandemic Impact Studies

Background:

• Understanding liquidity interlinkages is crucial for financial stability.
• The COVID-19 pandemic presented unprecedented economic shocks.
• Pre-existing sector-specific liquidity dynamics may influence crisis response.

Purpose of the Study:

• To analyze the impact of the COVID-19 pandemic on US industry liquidity networks.
• To identify changes in liquidity interrelationships before and during the pandemic.
• To quantify the differential effects of the pandemic across various industry groups.

Main Methods:

• Employed a lead-lag liquidity network methodology.
• Analyzed liquidity interrelationships beyond contemporaneous spillover effects.
• Compared network structures during the pre-COVID period versus the COVID-induced crisis.

Main Results:

• Significant differences in liquidity interactions were observed among US industry groups pre-COVID.
• The COVID-19 crisis led to a substantial increase in interconnectedness across all sectors.
• The utilities sector experienced the most pronounced increase in liquidity interlinkages, while telecommunication services were least affected.

Conclusions:

• The COVID-19 pandemic fundamentally altered liquidity network structures in the US.
• Sectoral heterogeneity in pre-pandemic liquidity linkages influenced the response to the crisis.
• The findings highlight the systemic nature of liquidity shocks during major crises.
