Bond yields are rising as investors brace for ECB rate hike and U.S. Treasury buybacks

The US Treasury has announced a bond buyback program of up to $6 billion, significantly larger than the previous maximum of $2 billion. This move aims to improve trading and liquidity in longer-term US government bonds, which have seen their yields hit their highest since November 2023. Despite the expansion, bond yields have continued to rise, with the 10-year, 20-year, and 30-year yields climbing to their highest levels since the previous three weeks.

Some analysts believe that the Treasury could have made a stronger statement with the buyback, suggesting that the $6 billion amount may only be the first step. The market is now monitoring whether the Treasury will increase its purchases if long-term yields continue to rise. While the buyback can help improve liquidity in older government bonds, its small size compared to the $32 trillion US Treasury market means it cannot significantly alter the broader supply-and-demand forces that have pushed long-term yields higher over the past few months.
