Liquidity Risk and Currency Premia
研究了外汇市场中流动性风险对货币超额收益的影响，发现流动性风险每年带来高达3.6%的风险溢价，且与利差交易溢价相关，为利差交易提供了流动性解释。
The currency market is the world’s largest financial market by trading volume. We show that even in this highly liquid market, exposure to liquidity risk commands an economically significant risk premium of up to 3.6% per year. Liquidity risk is not subsumed by existing currency risk factors and successfully prices the cross section of currency excess returns. Moreover, we find that liquidity risk and carry trade premia are correlated, although this correlation is limited to static rather than dynamic carry trades. Building on this result, we propose a liquidity-based explanation for the carry trade, which adds significant explanatory power to existing theories. This paper was accepted by Lukas Schmid, finance.
