Bank of England stress-tests private markets for global shock

The Bank of England is stress-testing the opaque corners of private finance for a global shock that would send equities down 35%, inflation up to 7% and Britain’s economy down 4%, with unemployment rising sharply. Regulators want to see whether banks and non-bank lenders active in private markets would help contain the damage or intensify it.

The exercise, published on June 19, 2026, is the Bank’s second system-wide exploratory scenario and is focused specifically on the private markets ecosystem. It assumes a severe but plausible global aggregate supply and geopolitical shock, including disrupted tech-hardware supply chains, higher energy prices, falling output, tighter financial conditions, higher borrowing costs, weak productivity growth, impaired exit markets and pressure on leveraged corporates. The Bank has said the scenario is hypothetical, a tail-risk event rather than a forecast, and broadly consistent in severity with its Bank Capital Stress Test.

More than 40 firms are taking part, including 17 alternative asset managers such as Apollo Global Management, Ares, Bain Capital and KKR. Participation by asset managers is voluntary because the Bank does not directly regulate them, but the exercise reaches well beyond hedge funds and buyout firms. The private markets ecosystem also includes insurers, pension funds, endowments and foundations, along with managers of private equity, private credit and collateralised loan obligations. The Bank wants to model how those institutions would react over five years and whether their collective behavior could transmit stress into wider financial markets, threaten UK financial stability and crimp financing to the real economy.

That concern is now shared by global watchdogs. The Financial Stability Board said in May that signs of underlying stress are emerging in private credit, a market it estimates at $1.5 trillion to $2 trillion. It also said direct bank credit-line exposures to private credit funds across its members are around $220 billion, with some commercial estimates ranging as high as $500 billion. The FSB has warned that deepening links between private credit funds, banks, insurers and private equity firms, along with leverage, liquidity mismatches, concentration and data gaps, could magnify losses in a downturn.

The Bank has long warned that the rapid growth of private markets, combined with opacity and interconnectedness, makes systemic risk harder to spot until it is already spreading. It said initial results from the exercise will be shared later this year, with a second round early next year before a final report. For investors, the message is clear: the era of easy money is gone, and the hidden plumbing of private finance is now under a brighter regulatory spotlight.
