Abstract
This paper examines customer demand-side factors that affect deviation from covered interest rate parity (CIP) with respect to the dollar (i.e., cross-currency basis), particularly when arbitrageurs are constrained. Using novel detailed daily transaction-level data on the universe of Israeli institutional investors (IIs), we employ a granular instrumental variable (GIV) estimation to investigate how IIs’ FX swap demand affects CIP deviation. Our findings demonstrate that a one standard deviation shock to IIs’ FX swap demand when capital is abundant has no effect on IIs’ basis. However, when capital is scarce, the demand shock produces a significant reduction of 12 basis points in IIs’ basis. Our results showcase how limits of arbitrage, together with demand shocks from a large customer base, can drive CIP deviations.
期刊介绍：
The Journal of International Economics is intended to serve as the primary outlet for theoretical and empirical research in all areas of international economics. These include, but are not limited to the following: trade patterns, commercial policy; international institutions; exchange rates; open economy macroeconomics; international finance; international factor mobility. The Journal especially encourages the submission of articles which are empirical in nature, or deal with issues of open economy macroeconomics and international finance. Theoretical work submitted to the Journal should be original in its motivation or modelling structure. Empirical analysis should be based on a theoretical framework, and should be capable of replication.
