Reversals in Global Market Integration and Funding Liquidity

This paper looks at the reversals in global financial integration through the funding liquidity lens. First, we construct a segmentation indicator based on differences in funding liquidity across countries as measured by the performance of betting-against-beta strategies. Second, we find that funding liquidity shocks help explain recent reversals in integration in the absence of explicit foreign investment barriers. These findings are consistent with tighter limits to arbitrage and increased home bias during funding distress periods. Our empirical analysis is guided by a margin-CAPM model generalized to an international setting.
