However, all three benchmark indices ended the week lower, with long-duration yields (US30Y) rising for the second consecutive week, primarily owing to the Treasury Department’s plan to buy back bonds.

Investor confidence got a mild boost on Friday after an S&P Global gauge showed U.S. business activity grew at its fastest pace in more than four years. 

In parallel, Bitcoin extended its winning streak to a fifth consecutive day, jumping as much as 9.4% to top $79,000—its sharpest single-day gain since February. Shares of Strategy Inc. advanced 6.1%, with other crypto-adjacent stocks following suit.

“The strong trigger in Bitcoin was driven by the Treasury’s move to buy back bonds at the longer end of the yield curve,” Bernstein analysts wrote in a note, referring to the Treasury Department’s announcements this week. “We are not macro experts, but we do know Bitcoin historically has had a positive reaction to liquidity expansion.”

On Friday, longer-dated yields continued their ascent, with the 10-year Treasury note yield gaining more than 3 basis points to 4.734%. The 30-year Treasury bond yield also advanced more than 3 basis points to 5.273%.
