Modeling Sterilized Interventions and Balance Sheet Effects of Monetary Policy in a New-Keynesian Framework

I. INTRODUCTION(3)
Finally, our analysis allows to compare the performance of a full range of hybrid exchange rate regimes in a common framework and look at some of the trade-offs.
Earlier analysesâconstrained by inadequate modeling approachesâfailed to highlight the advantages that active exchange rate management can have under certain circumstances, and the associated risks.
We thus believe our paper offers a good starting point for a fuller welfare analysis.
For instance, we illustrate the contrasting performance of exchange rate pegs maintained by interest rates and by interventions.
In the former case, monetary policy has to follow foreign interest rates in order to keep the exchange rate unchanged, which has implications for the rest of the economy.
In the latter, FX interventions may potentially insulate the domestic interest rates from such pressures, by acting instead on the interest rate wedge in the financial system.

While we believe our paper is the first to formalize the use of FX intervention alongside standard monetary policy rules in a new-Keynesian framework, it coincides with recent work by Ostry et al (2012).
These authors also argue that monetary policy in emerging markets is best characterized as having two targets (inflation and exchange rates) and two instruments (shortâterm interest rates and sterilized FX interventions), and that such regimes are preferable when deviations of exchange rates from mediumârun values are costly.
Our paper is also related to recent work on the use of unconventional monetary policy tools in advanced economies during the crisis (Curdia and Woodford (2011) and Gertler and Karadi (2011), among others).
These papers also present a quantitative toolâcredit policyârelated to the size of the central bank balance sheet and that operates alongside traditional instruments.
In their case, the unconventional tool is used to help minimize the impact of financial disruptions, especially when the policy rate hits the zero lower bound.

We differ from these papers in that our focus is on a different quantitative instrumentâsterilized interventionsâoperating on a different transmission channelâthe supply of central bank paper/FX funding available to the banking system.
In addition we view interventions as a regular policy tool rather than one used only during episodes of extreme financial distress.
