This has led to a lot of concern over inflation, but Federal Reserve Chairman Jerome Powell says any pressure on prices isn't something to panic over. 

"Those pressures are likely to be temporary, as they are associated with the reopening process," said Jerome Powell, chairman of the U.S. Federal Reserve.
