WASHINGTON (AP) – Federal Reserve Chair Jerome Powell has pledged to do whatever it takes to curb inflation, now raging at a four-decade high and defying the Fed’s efforts so far to tame it. Increasingly, it seems, doing so might require the one painful thing the Fed has sought to avoid: A recession. A worse-than-expected inflation report for May helped spur the Fed to raise its benchmark interest rate by three-quarters of point Wednesday and to signal that more large rate hikes are likely coming. Economic history suggests that aggressive, growth-killing rate hikes could be necessary to finally control inflation. And typically, that is a prescription for a recession.
