Abstract:The term structure of interest rates is the primary transmission channel of monetary policy. Under the expectations hypothesis, anticipated settings of the short-term interest rate controlled by the central bank are the main determinants of nominal bond rates. Historical experience suggests that bond rates may remain relatively high even if the short-term interest rate is reduced to zero, in part due to term premiums reflecting uncertainty about future policy. Term spreads due to policy uncertainty may be reduced by central bank trading desk options that provide insurance against future deviations from an announced interest rate policy. The term structure of interest rates is the primary transmission channel of monetary policy. Under the assumption that policy actions are summarized by movements in the one-period short rate, policy transmissions to the real economy are influenced more by market perceptions of monetary policy than by the current actions of the central bank trading desk in the spot market for the short rate.The main subject of this paper is the role of market perceptions of policy when expectations of long-term inflation are low and, consequently, the average level of nominal interest rates is significantly lower than the level of postwar rates. In critical episodes, such as a persistent recession where the short rate may be driven near zero, historical experience suggests long-term bond rates may remain well above zero. This paper indicates derivative securities issued by the trading desk may tighten connections between policy intentions for the short rate and current long-term interest rates. Discussion is directed principally at policy options to influence nominal yields on Treasury securities.Market perceptions embedded in long-term bond rates include both averages of expected future short-term rates and uncertainty about future policy responses, which is priced in the term premium components of bond rates. Market short rate forecasts and variances are based on conjectured or average-history descriptions of future policy. In the case of the latter, estimated policy response functions help agents to quantify representative policy responses to current and future events.Data-based characterizations of policy range from reduced-form time series models of the short rate to structural feedback rules, such as the calibrated example of Taylor (1993), where future short rate responses are conditioned on forecast indicators of the economy such as inflation and output deviations from trend. Because policymakers are subject to the same difficulties in forecasting future states of the economy as are private sector agents, it is usually unrealistic for policymakers to make unconditional forecasts of their future actions.However, in times of unusual economic stress, policymakers may wish to consider policy use of more explicit contingent contracts in order to transmit unambiguous signals to markets regarding the direction and volatility of the policy-controlled short rate over a near-term horizon of...
