According to online reports, Federal Reserve Chairman Powell said that the economic path is extremely uncertain and downside risks have increased. Uncertainty may be reflected in weak economic data; the risks of rising unemployment and rising inflation have risen but have not yet appeared in the data; the right thing to do is wait for further certainty. There are widespread concerns among businesses and households, and if nothing is done to alleviate these concerns, these concerns are expected to show up in data in the coming weeks or months.
