Introduction
Market liquidity spillovers have been extensively studied in both traditional fiat currencies and digital assets (cryptocurrencies), though typically in isolation. In today's globally interconnected financial markets, assets demonstrate complex interdependencies as economic actors make decisions spanning multiple asset classes.
This article examines daily liquidity metrics across:
- Five major cryptocurrencies (BTC, ETH, etc.)
- Seven key fiat currencies (EUR, USD, etc.)
Through time-frequency domain analysis, we uncover crucial insights about their dynamic relationships.
Key Findings
Event-Driven Liquidity Correlations
COVID-19 Pandemic Impact:
- Liquidity spillovers intensified during peak uncertainty periods
- Total spillover index showed stronger long-term than short-term effects
Primary Net Transmitters:
- Short-term: Euro (EUR)
- Long-term: Ethereum (ETH)
Economic Variable Influence:
- Distinct short/long-term driver heterogeneity
- Demonstrated through advanced econometric modeling
Implications for Market Participants
For Traders & Investors
Portfolio diversification strategies must account for:
- Crisis-period liquidity correlations
- Asymmetric transmission mechanisms
- 👉 Real-time liquidity monitoring tools can help identify spillover risks
For Policymakers
Financial stability frameworks should incorporate:
- Cross-market liquidity surveillance
- Crypto-forex interconnection mapping
