Rising long-term bond yields, currently at a historically high 5.3%, have prompted the U.S. Treasury to initiate an unscheduled expansion of its buyback program. This "Treasury Twist" aims to suppress long-dated yields by shortening the duration of outstanding debt through the issuance of bills to repurchase bonds. While initial market reactions were muted due to concurrent surges in oil prices linked to the conflict in Iran, the Treasury maintains a robust toolkit to further influence yields. Potential escalations include reducing long-end issuance sizes, incentivizing commercial banks to increase treasury holdings, or leveraging government-sponsored enterprises like Fannie Mae and Freddie Mac to purchase bonds. Although yield curve control remains a theoretical "nuclear option," the Treasury’s current focus centers on using its existing mechanisms to stabilize the market and signal its commitment to curbing rising interest rates.
