Private equity firms are facing significant challenges in fulfilling their commitments to institutional investors amid a prolonged period of market uncertainty and rising interest rates. For years, buyout funds have promised investors—typically pension funds and endowments—that locking up capital for several years would yield returns well above market averages, accompanied by timely distributions of both invested capital and profits. However, this promise has become increasingly difficult to honor.

The difficulties stem largely from a surge in acquisitions made during an extended era of historically low interest rates, especially in 2021 when the pandemic’s economic effects and rock-bottom borrowing costs fueled a buying spree. Many of those transactions were executed at peak valuations, creating obstacles for exit opportunities as interest rates rose sharply in 2022. Prospective buyers have been reluctant to pay prices comparable to prior deals, leaving private equity firms struggling to sell portfolio companies at anticipated premiums.

Further compounding the issue, some portfolio companies have underperformed due to pandemic-related disruptions, while advances in technology and geopolitical concerns have complicated their valuations. Traditionally, a successful buyout is expected to at least double a company’s value between acquisition and sale, allowing firms to return the majority of profits to their investors. Yet the industry’s so-called distribution rate—the pace at which invested capital and profits are returned—has declined markedly since 2022. While a similar downturn in distributions occurred during the 2008 global financial crisis, the current slowdown has proven more persistent.

Data indicate that the private equity sector holds a record volume of investments currently tied up in portfolio companies, estimated at $3.5 trillion to $3.8 trillion as of the end of 2025. Assets under management, which combine unspent capital commitments with investments in existing companies, have surged since 2019, with the proportion represented by existing holdings at its highest level in more than two decades. According to consultancy Bain & Company, the average holding period for private equity assets has extended to roughly seven years—up from five to six years over the previous decade—reflecting a slower pace of exits.

Although global exit values increased last year, the upward trend was primarily driven by a handful of megadeals, with seven large transactions accounting for 20 percent of total exit value, Bain reports. The tight distribution of cash returns has led investors to seek alternative strategies. Many have sold their stakes in funds to secondary market buyers, who typically leverage these older assets to enhance returns. Meanwhile, buyout firms have increasingly turned to continuation vehicles—new pools of capital gathered from fresh investors—to buy portfolio companies from their original funds. This approach aims to return some cash to initial investors while allowing the firms extra time to improve company performance and eventually achieve higher exit valuations.

It remains uncertain whether continuation vehicles provide a sustainable solution, as their success depends on future sales of the companies involved. The scarcity of cash distributions has also limited investors’ ability to reinvest in new private equity funds. While fundraising activity in the first half of this year shows signs of improvement compared with last year, the market remains highly concentrated. A relatively small number of funds are expected to capture the majority of capital commitments, marking the narrowest distribution of funds raised in over a decade.
