Foreign Exchange Intervention and Financial Stability

Abstract: This paper studies the effects of sterilized foreign exchange market intervention in an open-economy model with financial frictions and imperfect capital mobility. The central bank operates a managed float regime and issues sterilization bonds that are imperfect substitutes (as a result of economies of scope) to investment loans in bank portfolios. Sterilized intervention can be expansionary through a bank portfolio effect and may therefore raise financial stability risks. The model is parameterized and used to study the macroeconomic effects of, and policy responses to, capital inflows associated with a transitory shock to world interest rates. The results show that the optimal degree of exchange market intervention is more aggressive when the central bank can choose simultaneously the degree of sterilization; in that sense, the instruments are complements. At the same time, the presence of the bank portfolio effect implies that full sterilization is not optimal. By contrast, when the central bank’s objective function depends on the cost of sterilization, in addition to household welfare, intervention and sterilization are (partial) substitutes–independently of whether exchange rate and financial stability considerations also matter.
