The U.S. 30-year Treasury yield briefly rose to 5.7041% on Wednesday, a level not seen in 24 years as global bond yields moved higher again.

Data provider NS3.AI attributed the move to inflation worries, rising government debt concerns and a rebound in oil prices that weighed on markets.

Investors awaited the Federal Reserve's September policy meeting minutes and the day's 10-year Treasury note auction, which could influence demand for government debt.

A 30-year Treasury auction scheduled for Thursday was expected to test appetite for long-duration U.S. bonds.
