From Fed Chair Jerome Powell: Monetary Policy in the Post-Crisis Era. Excerpt:
In our baseline outlook, we expect growth in the United States to remain solid, labor markets to stay strong, and inflation to move back up and run near 2 percent. Uncertainties about this outlook have increased, however, particularly regarding trade developments and global growth. In addition, issues such as the U.S. federal debt ceiling and Brexit remain unresolved. FOMC participants have also raised concerns about a more prolonged shortfall in inflation below our 2 percent target. Market-based measures of inflation compensation have shifted down, and some survey-based expectations measures are near the bottom of their historical ranges.
Many FOMC participants judged at the time of our most recent meeting in June that the combination of these factors strengthens the case for a somewhat more accommodative stance of policy. We are carefully monitoring these developments and assessing their implications for the U.S economic outlook and inflation, and will act as appropriate to sustain the expansion, with a strong labor market and inflation near its symmetric 2 percent objective.
