For Treasury securities, when the caps are fully phased in, they will generally only be binding during the middle month of each quarter, when there is typically a spike in maturing Treasuries in the Fed’s portfolio. For agency MBS, as long as long-term interest rates are steady or rising, we expect that the fully-phased-in caps will not be binding. However, if long-term interest rates were to fall sharply—provoking a surge in refinancing and mortgage repayments—the caps would likely bind, limiting the amount of agency MBS that would have to be absorbed by the private market. As currently anticipated, once we start the balance sheet normalization program, we expect it to continue in the background until the FOMC judges that the Fed’s securities holdings are no larger than necessary to implement monetary policy efficiently and effectively. Adjustments to the target range of the federal funds rate will remain the primary tool of monetary policy. However, if economic circumstances were to change during the normalization process in a way that would warrant a sizable reduction in the target range for the federal funds rate, the FOMC would be prepared to resume reinvestment. The program has been designed to be implemented gradually and predictably so that market participants and the U.S. Treasury can anticipate when and at what pace the portfolio is likely to run off over the course of normalization. This should keep expectations more stable and reduce the risk that a sharp shift in expectations could generate undesirably large movements in interest rates and asset prices.

This judgment is supported by the fact that financial conditions have eased, rather than tightened, even as the Fed has raised its short-term interest rate target range by 75 basis points since last December. For example, equity prices have risen, credit spreads have narrowed modestly, longer-term interest rates have declined, and the dollar has weakened. On balance, these movements have been large relative to the upward drift in short-term interest rates. The easing in financial conditions is important because monetary policy does not directly influence the trajectory of economic growth and inflation. Instead, as I have noted in previous remarks, shortterm interest rate changes are an important factor that affects broad financial market conditions.2 Financial conditions, in turn, influence the demand for goods and services by households and businesses. But, if financial conditions ease even as we are removing monetary policy accommodation, this may have implications for further policy adjustments. All else equal, an easing of financial conditions may warrant a somewhat steeper policy rate path. Conversely, if financial conditions were to tighten unduly, then this might necessitate a shallower rate path to temper that tightening. To be clear, this does not mean that the Fed should mechanically target a particular set of financial conditions. That is because the set of financial conditions appropriate to achieving the Fed’s statutory objectives of maximum employment and price stability will evolve over time as the economic outlook changes. Financial conditions are just a means to an end—the achievement of the Fed’s employment and inflation objectives.
