Summary
Castlelake, a global alternative investment firm specializing in asset-based private credit, and Redwood Trust Inc. (NYSE: RWT), a mortgage REIT and housing finance platform operator, announced the formation of a strategic joint venture on April 29, 2026, designed to acquire up to $8 billion in prime jumbo mortgage loans. The partnership is structured to provide Castlelake with programmatic purchasing power for fully documented prime jumbo loans sourced through Redwood's Sequoia platform, the company's non-agency correspondent mortgage origination and aggregation business.
Under the joint venture framework, Sequoia will assume primary responsibility for sourcing, aggregating, and diligencing loans that meet defined eligibility criteria, enabling consistent execution and high-quality asset selection. The venture contemplates flexibility to scale acquisition volumes as opportunities emerge, including the potential purchase of seasoned loans from bank balance sheets—a meaningful capacity given current commercial real estate credit pressures and potential portfolio adjustments by traditional mortgage originators.
Redwood's Sequoia platform has demonstrated substantial momentum, with loan acquisition volumes more than doubling over the prior year, reflecting the company's growing market share in the jumbo mortgage segment. Brooke Carillo, Redwood Trust's executive vice president and chief financial officer, noted that the joint venture aligns with the company's strategic objective of scaling its platforms alongside leading institutional capital providers, positioning both firms to capitalize on a "dynamic and expanding opportunity set" in the non-agency mortgage market.
Lucas Jackson, head of North American residential mortgage finance at Castlelake, emphasized that the partnership is grounded in shared principles of disciplined underwriting and institutional governance. Jackson characterized the venture as reflecting Castlelake's granular, loan-level investment approach, designed to generate attractive risk-adjusted outcomes for the firm's institutional investor base through access to high-quality, fully documented prime jumbo assets.
The timing of the partnership reflects broader market conditions in the mortgage sector, as alternative capital providers expand their residential mortgage exposure amid evolving agency mortgage market dynamics and institutional investor appetite for non-agency residential credit strategies.
