From Fed Chair Powell: Recent Economic Developments and the Challenges Ahead
We should continue do what we can to manage downside risks to the outlook. One such risk is that COVID-19 cases might again rise to levels that more significantly limit economic activity, not to mention the tragic effects on lives and well-being. Managing this risk as the expansion continues will require following medical experts’ guidance, including using masks and social-distancing measures.
A second risk is that a prolonged slowing in the pace of improvement over time could trigger typical recessionary dynamics, as weakness feeds on weakness. A long period of unnecessarily slow progress could continue to exacerbate existing disparities in our economy. That would be tragic, especially in light of our country’s progress on these issues in the years leading up to the pandemic.
The expansion is still far from complete. At this early stage, I would argue that the risks of policy intervention are still asymmetric. Too little support would lead to a weak recovery, creating unnecessary hardship for households and businesses. Over time, household insolvencies and business bankruptcies would rise, harming the productive capacity of the economy, and holding back wage growth. By contrast, the risks of overdoing it seem, for now, to be smaller. Even if policy actions ultimately prove to be greater than needed, they will not go to waste. The recovery will be stronger and move faster if monetary policy and fiscal policy continue to work side by side to provide support to the economy until it is clearly out of the woods.
