Blackstone is exploring the sale of more than $2bn in stakes held in private investment funds. The transaction could become one of the largest deals of its kind and may serve as an important test for investor appetite toward older private equity assets.
The proposed structure is a collateralised fund obligation, or CFO. It would bundle stakes in leveraged buyout funds into bonds that can be sold to investors, including insurers. The aim is to generate liquidity for investors in a Blackstone Strategic Partners fund, the firm’s platform focused on investing in other private equity funds.
The deal has not yet been finalised. Blackstone could proceed with the securitisation or choose a more traditional secondary sale. Still, the attempt itself is significant. It reflects a broader pressure across private markets: investors want cash returns, while many buyout funds are struggling to sell portfolio companies at attractive valuations.
A Market Still Absorbing the 2020–2022 Investment Cycle
The private equity industry is facing a large inventory problem. Buyout firms are estimated to hold around $4tn in unsold assets. Many of these investments were made between 2020 and 2022, when interest rates were close to zero and valuations were high.
That environment changed sharply after central banks raised rates. Higher borrowing costs reduced the appeal of leveraged deals. At the same time, weaker valuations made exits harder. Initial public offerings, corporate sales, and sponsor-to-sponsor transactions became more difficult to execute.
For many institutional investors, this created a liquidity gap. Pension funds, endowments, and sovereign wealth funds committed large amounts of capital to private markets. They expected distributions from older funds to help finance new commitments. When exits slowed, cash recycling became more constrained.
This is why transactions such as Blackstone’s are important. They show how private capital managers are using financial engineering to unlock liquidity from assets that are difficult to sell directly.
Why CFOs Are Becoming More Popular
Collateralised fund obligations have become an increasingly visible tool in private markets. These vehicles transform portfolios of private fund stakes into securities with different levels of risk and return. Investors can choose senior bonds with lower risk or more junior tranches with higher potential returns.
This structure is attractive to certain institutional buyers. Insurers, in particular, often seek rated securities that can fit within their capital and regulatory frameworks. Through CFOs, they can gain exposure to private equity-related cash flows while holding instruments that resemble credit products.
The market has grown quickly. CFO issuance reached a record $25.9bn last year, compared with $4.8bn in 2021. This rapid increase shows how private market liquidity tools are moving from niche solutions toward a larger part of the capital markets ecosystem.
Blackstone’s potential $2bn transaction would stand out even in this expanding market. For comparison, Carlyle completed a $1.25bn publicly rated CFO last year, while Coller Capital raised $2.4bn through a private structured funding vehicle backed by Barings and Ares Management.
Investor Demand Is Becoming More Selective
Despite strong growth, the CFO market is not without challenges. A larger number of deals means investors can be more selective. Recent transactions have reportedly taken longer to attract demand, especially for the riskiest parts of the structure.
The equity tranche is likely to be a key point of focus. This portion absorbs the highest risk but also offers the highest return potential. Demand for this layer will help indicate how much confidence investors still have in ageing private equity portfolios.
Market conditions also matter. Tariff-related turbulence in 2025 and geopolitical pressure linked to the war in Iran added uncertainty to exit markets. These factors affected the sale and listing of highly leveraged private-equity-backed companies.
As a result, investors are likely to assess more than headline deal size. They will look closely at the quality of the underlying funds, diversification, expected cash flows, valuation assumptions, and the maturity profile of the assets.
A Signal for the Future of Private Capital
Blackstone’s potential transaction reflects a wider evolution in private markets. The industry is no longer focused only on raising capital and buying companies. It must also create credible liquidity channels for investors.
This is becoming a strategic issue. If limited partners receive fewer distributions, they may reduce new commitments. That could affect future fundraising across private equity, private credit, infrastructure, and real assets.
Structured solutions such as CFOs may help ease this pressure. They can connect private equity portfolios with credit investors and insurance capital. However, they also introduce complexity. The long-term success of the market will depend on transparency, asset quality, ratings discipline, and investor confidence.
For now, Blackstone’s proposed $2bn deal is more than a single transaction. It is a market signal. Private capital is adapting to a slower exit environment, and liquidity is becoming one of the most important competitive advantages in the industry.
