> A synthetic GIC includes an asset ownership component and a contractual component that is intended to be valued at book value. The associated assets backing the contract’s book value are owned and held in the name of the plan or the plan’s trustee. Such associated assets typically consist of a diversified fixed income portfolio, including but not limited to treasury, government, mortgage, and/or corporate securities of high average credit quality. To support the book value obligation, the contract-holder relies first on any associated assets and then, to the extent those assets are insufficient, the financial backing of the wrap issuer. Wrap contracts can be issued by banks, insurance companies, or other financial institutions.

Again, you clearly don’t know what you’re talking about lol

Even if the combined yield in a hypothetical synthetic GIC portfolio was 0 (they weren’t) and insurers expect that portion of their investment portfolio to be lower, rates simply increase for policy holders. It’s not magic and they all abide by the same rules.
