The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
Market reaction to a change in official interest rates will depend on the extent to which the change is anticipated, and on how it is interpreted as a signal of future policy. In this paper, a technique is developed to separate the anticipated and unanticipated components of such changes and is applied to estimate the response of Euro-deutsch mark interest rates to adjustments in the Bundesbank’s Lombard and discount rates. The results shed light on the efficiency of this market and on the scope for policy signaling by the central bank.
