In a further indication that the Federal Reserve will be inclined to let inflation run hot for a while, Chair Janet Yellen on Friday said it's useful to consider the benefits of a "high-pressure economy."
Normal times call for the U.S. central bank to stand vigilant watch over price pressures. However, Yellen said the post-financial crisis period has pushed policymakers into reconsidering the dynamics of inflation.
She pointed out that the economy has seen an unusual tendency of weak demand against strong supply, making it reasonable "to ask whether it might be possible to reverse these adverse supply-side effects by temporarily running a 'high-pressure economy,' with robust aggregate demand and a tight labor market."
Yellen made the remarks at the Boston Fed in a speech that offered few clues otherwise about the near-term future of monetary policy.
The policymaking Federal Open Market Committee hasn't approved an interest rate increase since December 2015.However, pressure is building. Three FOMC members dissented at the September meeting, believing the committee should have raised it key funds rate a quarter-point. Traders believe there's about a 65 percent chance the committee will hike in December.
