On the term structure of liquidity in the European sovereign bond market
利用MTS平台高频数据，分析了欧元区主权债券市场在平静期和危机期的流动性动态，发现投资者在流动性枯竭时转向短期基准，且外围国家流动性不足对市场有重要影响。
The paper provides a high-frequency analysis of liquidity dynamics in the eurozone sovereign bond market over tranquil and crisis periods. We study time series of liquidity across the yield curve using high-frequency data from MTS, one of Europe’s leading electronic fixed-income trading platforms. We document flight-to-liquidity effects as investors prefer to trade on shorter-term benchmarks during liquidity dry-ups. We provide evidence of significant commonalities in spread and depth liquidity proxies which are weaker during the crisis period for both core and periphery economies although periphery countries display higher commonality than core countries during the crisis. We show that illiquidity of the periphery countries plays an important role in market dynamics and Granger causes illiquidity, volatility, returns, and CDS spreads across the maturity spectrum in both calm and crisis periods. Liquidity is priced both as a characteristic and as a risk factor even when controlling for credit risk, pointing to liquidity’s systematic dimension and importance.
