Woofun AI reports that JPMorgan strategists advise closing positions on the flattening of the 10-year to 30-year U.S. Treasury yield curve ahead of the U.S. CPI release and Federal Reserve Chairman Waller's congressional testimony. The firm cites upcoming event risks, noting that geopolitical tensions and hawkish Fed remarks drove short-end yields up by 6 basis points while flattening the curve by 3 basis points. Waller warned that entrenched high inflation could force the Federal Reserve to consider tightening monetary policy if core inflation pressures remain strong.
