Short sellers double bets on life insurers

Short sellers have piled into U.S. life-insurance stocks, pushing total bearish bets on the sector above $5 billion, according to a Reuters analysis of ORTEX data. (reuters.com) The move reflects a market fight over private credit, the fast-growing business of loans made outside traditional banks. Life insurers buy those loans because their long-dated payouts can match the long-term cash flows from the debt. (naic.org) (chicagofed.org) Reuters reported that short interest in the group has more than doubled over the past year, with Brighthouse Financial, Lincoln National and Corebridge Financial among the names drawing the heaviest bets. (reuters.com) The core concern is valuation. Some insurer holdings sit in Level III accounting buckets, which means prices rely more on internal models than on frequent market trades. (fitchratings.com) Fitch said in October 2025 that life insurers tied to alternative asset managers carry above-average exposure to private credit and Level III assets, which can raise valuation, liquidity and concentration risk. (fitchratings.com) The private-credit market reached about $1.8 trillion in 2023, according to the National Association of Insurance Commissioners, and the regulator said life insurers are major participants because the assets fit long-term liabilities. (naic.org) A June 2025 Chicago Federal Reserve paper said life insurers held $849 billion of private placements in 2024, equal to 14% of their balance sheets. The authors said much of the growth came from lending to financial borrowers and privately placed asset-backed securities. (chicagofed.org) Regulators have already started digging deeper. S&P Global Market Intelligence reported in March that the National Association of Insurance Commissioners reworked its investment oversight structure in 2025 and is focusing more closely on private credit and ratings practices. (spglobal.com) Insurers and ratings analysts have also argued the risks are not uniform. Fitch said diversified portfolios, asset-liability matching and capital buffers should limit broad rating pressure even if private-credit performance weakens over the next one to two years.
