Following the markets' adverse reaction to the FOMC statement that cited increased concern about foreign economic activity, Yellen and other Fed officials made sure to reassure markets this week. Yellen's speech last evening was key, in which she argued that rate lift-off is still on track for this year. Revised Q2 GDP data showed the economy rebounded strongly in Q2, advancing at a 3.9% pace, following the sluggish 0.6% increase in Q1. Other data suggest sturdy domestic economic activity.
