(RTTNews) - Federal Reserve Chair Jerome Powell will warn members of the Senate Banking Committee about upside risks to inflation during testimony on Tuesday. Powell warned supply bottlenecks, hiring difficulties, and other constraints could prove to be greater and more enduring as the economic reopening continues, posing upside risks to inflation. Powell also noted that the economy has continued to strengthen since he last appeared before the committee but acknowledged the recent rise in Covid-19 cases has slowed the recovery in the sectors most adversely affected by the pandemic.
