Treasuries held small gains in early US trading Monday, supported by a slump in oil prices and a rally in UK government bonds, and by anticipation of buying into Tuesday’s month-end index rebalancing.

Yields were lower, the two-year by about a basis point and long maturities by as much as three basis points, remaining inside last week’s ranges. US benchmark crude oil futures were down about 2% on signs OPEC+ will hike production again in November.
