Some officials have argued for slowing the pace of rate rises after this week’s meeting. But the debate over the speed of increases could obscure a more important one around how high rates ultimately rise. In economic projections released at the Fed’s last meeting in mid-September, most officials anticipated their policy rate would reach at least 4.6% by early next year. But some economists think it will have to go higher than 4.6%, citing in particular reduced sensitivity of spending to higher interest rates.
