Pension risk transfer (PRT) has established itself as an incredibly important tool in the pension risk management toolkit, enabling plan sponsors to effectively manage pension liabilities and reduce financial risk. Historically, PRT was almost exclusively attained through group annuity buy-outs, which remain the dominant strategy. However, in recent years, group annuity buy-ins have garnered increased attention.
In 2024, buy-in premiums represented only 7% of the total PRT market. Meanwhile, in 2025, buy-in premiums made up over 35% of the PRT market. It's important to note that premium comparisons can be skewed by a few very large transactions; while buy-in premiums were over 35% of the market in 2025, buy-in contracts (i.e., the number of buy-in transactions) made up less than 3% of the overall number of PRT contracts.*
Buy-outs continue to outpace buy-ins in total premiums and contracts, maintaining their position as the preferred strategy for many sponsors. Buy-outs offer comprehensive risk transfer and balance sheet reduction, as well as Pension Benefit Guaranty Corporation (PBGC) premium savings and administrative relief, making them the go-to option for those seeking to fully offload pension liabilities.
While buy-ins have gained traction, their trade-offs may outweigh their merits in many circumstances. This article explores the mechanics of buy-ins and buy-outs, the key differences between the two strategies, recent trends in their adoption and situations where a buy-in might be preferable.
