Short Sellers Target PE-Owned Life Insurers Over Massive Private Credit Exposures

The growing nexus between private equity (PE) firms and life insurance companies has emerged as a major focal point of systemic risk in 2026. Private equity firms have aggressively acquired life insurance and annuity businesses, redirecting policyholder reserves into proprietary, illiquid private credit funds to harvest higher yields.

This opaque arrangement has triggered a massive surge in short-selling activity against U.S. life insurers, alongside unprecedented regulatory coordination between the U.S. Treasury Department and state insurance commissioners.

The Scale of Insurer Private Credit Buildup

According to the International Monetary Fund (IMF) and Moody's, U.S. life insurers have allocated approximately one-third (35%) of their sector's $6 trillion in assets—nearly $1 trillion—to private credit investments, up from 22% a decade ago. In the United Kingdom, private credit accounts for roughly a quarter of total insurer assets, and as much as 45% for some specific firms.

To obscure the risk of these illiquid assets, insurers have increasingly shifted assets into offshore, opaque subsidiaries. Former U.S. insurance examiner Tom Gober calculates that insurers have made about $1.54 trillion worth of transactions into offshore captive insurance companies, allowing them to hide risks and bypass domestic capital requirements.

"Rating Agency Arbitrage" and Regulatory Opacity

A key driver of this exposure is the reliance on private credit ratings issued by smaller, specialized rating agencies rather than major agencies (S&P, Moody's, Fitch). According to the IMF, the number of private securities rated by specialized agencies grew from 2,000 in 2019 to over 7,000 in 2023.

Moody's reports that while only one-ninth of U.S. life insurers' fixed-income holdings carry private ratings, this share exceeds 50% for Level 3 holdings—assets that are the most illiquid, hardest to value, and priced using internal assumptions.

In November 2025, UBS Chairman Colm Kelleher publicly warned that this practice constitutes a "looming systemic risk" to global finance, comparing it to the rating-agency arbitrage that precipitated the 2008 subprime crisis:

The insurance industry is engaging in "rating agency arbitrage" comparable to what banks did with subprime assets before 2008, pointing to a "massive growth in small rating agencies ticking the box for compliance."

The Bank for International Settlements (BIS) has similarly cautioned that smaller rating agencies "may face commercial incentives" to provide more favorable grades, leading to inflated assessments of creditworthiness for insurers seeking lower risk-based capital requirements.

Short Sellers Swarm U.S. Life Insurers

Sensing a structural mismatch between illiquid underlying assets and insurers' long-term payout obligations, short sellers have heavily targeted the sector. By April 2026, short bets against U.S. life insurance stocks more than doubled over the past year to over $5 billion. Globally, short bets against insurance firms grew by more than 60% to over $31 billion.

Specific targets include:

• Brighthouse Financial (BHF): Short positions reached a record high of over 13% of available stock on March 9, 2026.
• Principal Financial Group (PFG): Short positions soared more than 80% over the past year, peaking over 4% in March 2026.
• Prudential (PRU): Short positions rose from 1.96% to 3.27%.

Alberto Gallo, founder of hedge fund Andromeda Capital (which holds short positions on insurers' bonds), noted:

"Life insurers owned by PE (private equity) firms are very long private assets and have very limited capital surplus available."

Coordinated Regulatory Response: May 2026 Treasury Convening

In response to these mounting risks, U.S. Treasury Secretary Scott Bessent hosted a high-level convening on May 7, 2026, with state insurance commissioners and the National Association of Insurance Commissioners (NAIC).

The official Treasury statement confirmed that the meeting focused on:

• Recent developments in private credit markets.
• The movement of U.S. life and annuity reserves to offshore jurisdictions (captives).
• State and NAIC regulatory responses, including work on risk-based capital, private letter ratings, offshore reinsurance jurisdictions, and the oversight of evolving PE-owned business models.
