Bond prices climbed after the U.S. Treasury Department announced larger liquidity support buybacks for longer-dated government debt. Starting September 9, the maximum purchase size will increase from $2 billion to at least $4 billion per operation. The change covers nominal coupon securities in the 10-to-20-year and 20-to-30-year maturity sectors. The increased amounts will remain in effect through November 4. The department said strong volumes of high-quality offers supported the decision to increase liquidity operations in those sectors.
