Life/health net yield rises to 4.6%

The U.S. life/health industry earned a 4.6% net yield on invested assets in 2025, up 10 basis points from the prior year in AM Best's new asset-distribution rankings. The gain works out to 2.2% against a 4.5% base, and for a measure that prices the entire balance sheet it is where a decision about the marginal dollar first shows up.

Higher public yields changed the math on private allocations for insurers, as this publication has argued, driving rotation within private assets rather than retreat, and the yield line is where that rotation lands. A 4.6% life/health yield suggests the marginal dollar went somewhere the public curve cannot reach — into assets whose returns carry a premium for supply constraints or construction risk. Structured credit and investment-grade private debt are the natural settings for that premium, with commercial real estate debt the latest rotation target.

The aggregate yield is the first number the market sees in Best's asset-distribution rankings, but the split behind it matters just as much. If the gain came from the private sleeve, 4.6% is the first visible payment on a multi-year shift in how life/health insurers underwrite the balance sheet; if it came from public coupons, the number is simpler and less durable.

The assets selected this year will set the income line for years, so a single-year 10-basis-point gain is the income statement's version of a balance-sheet decision: the general account is becoming an underwriter of supply constraints, not just a lender. That posture carries a specific risk, because marks on supply-constrained assets can move before the yield is banked, and a pause or reversal in public rates would test the trade in a way a simple duration extension would not.

The next repricing of private-asset marks will be the test, and the general accounts that added the yield because they underwrote real-asset construction risk will be the ones whose numbers survive it. The asset-distribution detail behind Best's headline is where the answer shows up first.
