Previously, the U.S. Treasury Department announced that it is planning to at least double the size of its liquidity support repurchase operations for long-term nominal Treasury securities, involving two maturity ranges: 10 to 20 years and 20 to 30 years. Currently, the maximum size per operation is $2 billion, and in the future, the size per operation will be increased to at least $4 billion.

This expansion of the repurchase operation size reflects the Treasury Department's intention to provide stronger liquidity support to the long-term Treasury market. The Treasury Department will later announce the updated arrangements for the temporary Treasury repurchase.
