TREASURIES-US yields advance ahead of 30-year bond auction, comments from Fed’s Powell

Investors sold Treasuries ahead of Thursday's $24 billion sale in U.S. 30-year bonds, the last of the notes and bond offerings this week, with intent to buy them back at a lower price in what is known as a "supply concession." The U.S. Treasury sold three-year and 10-year notes earlier in the week, which analysts said came out relatively better than expected, given the increase in auction sizes from the previous month.
