In a recent statement, billionaire investor William Ackman revealed that his hedge fund Pershing Square Capital Management has taken a position against U.S. 30-year Treasuries as a way to protect against the impact of increasing long-term rates on stocks. Ackman emphasized that if long-term inflation exceeds 2% and reaches 3%, the yield on 30-year Treasuries could potentially rise to 5.5%, and this shift might occur sooner than expected. The yield on 30-year Treasuries hit 4.16% on Wednesday, marking the highest closing level so far this year.
