Nick Timiraos, a reporter for The Wall Street Journal, relayed the views of former Dallas Federal Reserve President Rob Kaplan. Kaplan noted that if supply shocks only last two months, the Federal Reserve should choose to wait and see; however, if the shocks persist for six to eight months or longer, inflation will begin to spread to other goods, at which point the Federal Reserve may need to take policy actions, such as raising interest rates, to slow or prevent inflation from transmitting to broader areas.
