Comments from Boston Fed President Eric Rosengren:

  • Good reasons to expect tightening to be gradual
  • US labor market has 'largely' met FOMC conditions
  • Reasonable confidence on inflation not as clear cut
  • Weaker global growth may dim outlook for US jobs
  • A much weaker global economy increases uncertainty
  • Long-run Fed funds may be lower than previous cycle

Rosengren is a voter in 2016. He has a reputation as a dove but he's scaled it back in recent years.
Update:

  • Oil fall could bring less US inflationary pressure
  • China, Europe, Japan economic weakness could depress inflation
  • Surprised by lower US productivity, hopes it rebounds
  • Fed missing on inflation mandate a reason to keep rates 'fairly' low
