- • Bock also stepped down from his co-CEO role at the Blackstone Secured Lending Fund, further consolidating leadership within Blackstone's private credit platform.
- • The resignation was characterized as non-contentious, with Blackstone stating it was unrelated to any disagreement regarding fund operations, policies, or practices.
- • BCRED manages approximately $78 billion in assets but experienced a 1.2% decline in net asset value during June, a performance decline larger than some comparable funds, suggesting company-specific factors may have driven underperformance.

Summary
Jonathan Bock has resigned as co-chief executive of Blackstone's flagship private credit fund, effective July 20, 2026. The departure leaves Brad Marshall as the vehicle's sole chief executive, with Blackstone confirming it will not appoint a replacement for the co-CEO position. Bock simultaneously resigned from his co-CEO role at the Blackstone Secured Lending Fund, which operates as part of Blackstone's broader private credit platform.
According to regulatory filings cited by Bloomberg, Blackstone characterized the resignation as unrelated to any disagreement with the firm or concerns regarding fund operations, policies, or practices. A company statement noted that "during his tenure, Mr Bock made valuable contributions to the Blackstone Credit & Insurance perpetual credit funds platform," suggesting an amicable departure rather than a forced exit or internal conflict.
Bock joined Blackstone in 2023 after establishing himself as a business development company specialist at Wells Fargo, where he launched the quarterly BDC Scorecard publication. Prior to his Blackstone appointment, he led the BDC business at Barings. His relatively brief tenure at Blackstone coincides with heightened scrutiny of the firm's private credit operations.
The resignation occurs amid a period of leadership transition at BCRED, which manages approximately $78 billion in assets. Katherine Rubenstein departed as chief operating officer in June 2026, preceding Bock's exit by roughly one month. More significantly, BCRED's net asset value declined 1.2% in June, a larger contraction than some peer funds experienced, prompting market analysts to attribute the performance decline to company-specific factors rather than broader market headwinds. This performance weakness adds context to the leadership departures, though Blackstone has not explicitly connected the two developments.
