Foreign Exchange Intervention Rules for Central Banks: A Risk-based Framework

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.

Risk Management for Central Bank Foreign Reserves

Central Bank Emergency Support to Securities Markets

This paper considers the central bank mandate with respect to financial stability and identifies the links to the functioning of securities markets. It argues that while emergency support to securities markets is an important part of the crisis management response, a high bar should be set for its use. Importantly, it should be used only as part of a comprehensive policy package. The paper considers what types of securities markets may be important for financial stability, what market conditions could trigger emergency support measures, and how programs can be designed to restore market functioning while minimizing moral hazard.
