Here are the two key paragraphs regarding future interest rate changes from today's speech:
"In the statement issued after its March meeting, the FOMC noted that economic growth had rebounded strongly in the first quarter but appeared likely to moderate to a more sustainable pace. It further noted that a number of factors have contributed to the stability in core inflation. However, the Committee also viewed the possibility that core inflation might rise as a risk to the achievement of its mandated objectives, and it judged that some further policy firming may be needed to keep the risks to the attainment of both sustainable economic growth and price stability roughly in balance. In my view, data arriving since the meeting have not materially changed that assessment of the risks. To support continued healthy growth of the economy, vigilance in regard to inflation is essential.
"The FOMC will continue to monitor the incoming data closely to assess the prospects for both growth and inflation. In particular, even if in the Committee's judgment the risks to its objectives are not entirely balanced, at some point in the future the Committee may decide to take no action at one or more meetings in the interest of allowing more time to receive information relevant to the outlook. Of course, a decision to take no action at a particular meeting does not preclude actions at subsequent meetings, and the Committee will not hesitate to act when it determines that doing so is needed to foster the achievement of the Federal Reserve's mandated objectives."
