This exercise now has more impetus on expectations that junk bond prices will continue to rally in the wake of Powell's comments, which raised hopes of slowing rate hikes and a so-called economic soft landing.
Junk bond spreads on average tightened 37 basis points on Wednesday, the day of Powell's remarks, from a day earlier, according to ICE BAML data.
This is around the level in September when banks sold only about half of the total $15 billion of debt through a U.S. dollar bond, leveraged loan and a Euro-denominated loan.
Reuters could not confirm the exact amount sold in these sales and balance of LBO debt still left with banks.
Banks could consider selling larger parcels of LBO debt in the primary bond markets where there has been a surge in new issue supply, said the sources.
