The U.S. Treasury will repurchase up to $6 billion of outstanding Treasuries with maturities of 10 to 20 years, using an expanded long-term bond buyback facility. The Treasury raised the maximum size for such operations from $2 billion to $6 billion and will determine final purchases after reviewing prices submitted by sellers. The plan was described as part of a liquidity support program. The existing report had said the operation would occur on Thursday, while a Walter Bloomberg report dated October 7 referred to an October 1 operation.
