U.S. Treasury yields dipped on Wednesday, after a report showing the labor market remained tight last month, hours before a Federal Reserve decision on whether the economy is too strong, and inflation too sticky, to pivot to an easier rate policy soon. According to the ADP Employment report, private payrolls increased by 192,000 after rising by an upwardly revised 208,000 in March. But rates were overall hardly moving, nosing off again after the U.S. Treasury Department announced a total refunding of $125 billion for the May to July quarter that would raise new cash of $17.2 billion.
