Treasuries slipped, marginally underperforming peers as investors awaited the Federal Reserve’s preferred inflation gauge for clues on whether policymakers will need to raise interest rates. US yields rose two basis points across the curve, with the 10-year rate at 4.65%, even as Brent crude prices tumbled. Traders maintained bets on a quarter-point Fed hike this year, while pricing a more than 60% chance of a second by the middle of next year.
