Yellen Says Unwise to Keep Monetary Policy on Hold

Federal Reserve Chair Janet Yellen said gradually raising interest rates is the most appropriate policy approach amid higher uncertainty about inflation, reinforcing the US central bank’s forecast for another hike this year.

“It would be imprudent to keep monetary policy on hold until inflation is back to 2%,” she said Tuesday in Cleveland. In addition, she said the Fed “should also be wary of moving too gradually,” Bloomberg reported.

US central bankers are monitoring progress on their 2% inflation goal, which they have mostly missed for the past five years. Nonetheless, the Fed’s quarterly forecasts released last week continued to show most members projecting one additional rate hike this year and three more in 2018.

Investors in debt markets are pricing securities with the assumption that “a hike needs to be proven rather than disproven,” said Michael Hanson, chief US macro strategist at TD Securities in New York. “Yellen is saying we need to have a hike disproven.”

Investors now see a roughly 70% probability of a hike at the Fed’s December meeting, up from 63% on Monday.

Yellen, in her most detailed speech on inflation risks this year, described three areas of uncertainty in the inflation outlook. “My colleagues and I may have misjudged the strength of the labor market, the degree to which longer-run inflation expectations are consistent with our inflation objective, or even the fundamental forces driving inflation,” she said.

Discussing each of these risks, Yellen said it’s possible that some slack in the labor market remains.

“If so, the economy could sustain a higher level of employment and output in the longer run than now anticipated—a very beneficial outcome, albeit one that would require recalibrating monetary policy over time in order to reap those benefits and compensate for the accompanying reduction in inflationary pressures,” she said.

Yellen said the messages from survey and market measures of inflation expectations are mixed. Another risk, she added, is that there are underlying changes in firms’ and consumers’ behavior which are keeping prices low. Those forces range from foreign competition, to the growing importance of global supply chains in the production of goods, to online shopping.

Given all the uncertainties, Yellen said the policy makers will have to remain agile and be prepared to change their interest-rate assumptions. “My colleagues and I must be ready to adjust our assessments of economic conditions and the outlook when new data warrant it,” she said.
