Fed's Rare 8-4 Dissent Tests Fixed Annuity Credited Rate Assumptions

From tracking FOMC decisions and their downstream effects on life insurance general account portfolios, certain vote patterns demand immediate attention from pricing actuaries. The April 29, 2026 decision was one of those moments. The Committee voted to hold the federal funds rate at 3.50%–3.75%, but the 8-4 split revealed a fracture that has direct consequences for how carriers set credited rates on multi-year guaranteed annuities, fixed deferred products, and the indexed annuity option budgets that depend on general account earned rates.

Governor Stephen Miran dissented in favor of a 25-basis-point cut. Cleveland Fed President Beth Hammack, Minneapolis Fed President Neel Kashkari, and Dallas Fed President Lorie Logan also dissented, but for the opposite reason: they opposed the inclusion of easing-bias language in the statement. Hammack cited “broad based” inflation pressures. Logan expressed concern about the path back to the 2% target. The statement itself flagged Middle East developments as “contributing to a high level of uncertainty about the economic outlook” and noted that inflation remained “elevated, in part reflecting the recent increase in global energy prices.”

Four dissents had not occurred at an FOMC meeting since October 1992. For life actuaries, the significance is not the vote count itself but what it implies about the distribution of future rate paths that feed pricing models.

The Portfolio Rate Method: How Credited Rates Actually Get Set

The credited rate on a fixed annuity is not pegged directly to the federal funds rate or the Treasury curve. It is derived from the portfolio earned rate of the insurer’s general account, and the mechanics of that derivation determine how quickly Fed actions transmit into product pricing.

The core formula is straightforward:

Credited Rate = Portfolio Earned Rate − Investment Spread − Expense and Profit Charges

The portfolio earned rate is a duration-weighted average of coupon income across all asset segments backing the annuity block. For a large life insurer, the general account holds predominantly investment-grade corporate bonds (typically 60–70% of assets), with smaller allocations to structured securities, commercial mortgage loans, and alternatives. Because these bonds have maturities of 5 to 10 years on average, the portfolio yield reflects not current market rates but a rolling blend of rates at which assets were purchased over the preceding decade.

This is where the distinction between the portfolio method and the new-money method becomes critical. Under the portfolio method, all contracts in a given product class earn the same credited rate, regardless of when the premium was received. The rate reflects the blended yield of the entire asset portfolio. Under the new-money method, each generation of deposits is credited a rate based on the prevailing yield at the time of deposit. Most carriers use a hybrid approach: new-money rates influence the marginal pricing of new sales, while the portfolio rate governs the credited rate on in-force business.

The asset turnover rate determines how fast new-money yields flow into the portfolio rate. If 12% of the general account portfolio matures or is reinvested each year, it takes roughly eight years for a rate shock to fully permeate the portfolio yield. A 50-basis-point change in the 5-year Treasury therefore shows up as approximately a 6-basis-point first-year impact on the portfolio earned rate, assuming proportional reinvestment. This lag is the core buffer that protects credited rates from short-term volatility, but it also means that pricing actuaries must project the trajectory of reinvestment rates across the entire guarantee period when setting credited rate floors for new MYGA issues.

Investment Spread Management Under Bimodal Scenarios

The investment spread is where the carrier earns its margin. A typical target spread for a fixed annuity block runs 125 to 175 basis points, covering expense charges (20–40 bps), default risk provisions (15–30 bps), and profit margin (the remainder). When the portfolio earned rate is 5.25% and the target spread is 150 bps, the maximum credited rate is 3.75%. Every 25-basis-point decline in the portfolio earned rate compresses the credited rate by the same amount, assuming the carrier holds its spread target.

The 8-4 FOMC split creates two competing paths for the new-money component of the portfolio rate:

Scenario A (the Miran path): The funds rate moves to 3.25%–3.50% at the June or July meeting, with an additional cut to 3.00%–3.25% by year-end. In this scenario, the 5-year Treasury yield (currently near 4.10%) declines toward 3.70%–3.85%, and new-money yields on investment-grade corporates (which price at a spread to Treasuries) fall proportionally. The portfolio earned rate for new MYGA cohorts declines, compressing the credited rate floor.

Scenario B (the Hammack-Kashkari-Logan path): The funds rate holds at 3.50%–3.75% through year-end 2026, with the easing bias removed from forward guidance. In this scenario, the 5-year Treasury yield holds near 4.10%–4.30% or drifts higher on inflation repricing. New-money yields remain elevated, and carriers can sustain or even increase credited rates on new MYGA issues.

The problem for pricing actuaries is that these scenarios produce materially different credited rate floors, and a MYGA guarantee period of 5 to 7 years spans the entire window over which the divergence plays out. A carrier that prices to Scenario A (declining rates) builds in a credited rate floor that may be uncompetitive if Scenario B materializes. A carrier that prices to Scenario B (stable or rising rates) risks margin compression if rates decline sharply.

Credited Rate Floor Sensitivity: A Worked Example

Consider a 5-year MYGA with a guarantee period matching the term. The pricing actuary must set a credited rate that satisfies three constraints simultaneously: (1) competitive positioning against rival carriers and bank CDs, (2) a minimum investment spread that covers expenses and profit targets, and (3) a reserve floor that passes asset adequacy testing under VM-22.

The following table illustrates how a 50-basis-point swing in the 5-year Treasury yield affects the credited rate floor across three MYGA terms, holding the target investment spread constant at 150 basis points and the expense/profit charge at 35 basis points:

MYGA Term	5-Yr Treasury at 4.30%	5-Yr Treasury at 3.80%	Credited Rate Change
3-Year	4.85%	4.35%	−50 bps
5-Year	5.10%	4.60%	−50 bps
7-Year	5.30%	4.80%	−50 bps

Assumptions: IG corporate spread of 140 bps over Treasuries; new-money reinvestment at matched duration; target investment spread of 150 bps; expense/profit charge of 35 bps. Credited rate = new-money yield on matched-duration IG corporates − 185 bps (spread + expenses).

The sensitivity is nearly one-for-one: a 50 bps move in the benchmark translates to a 50 bps move in the credited rate floor. This is because a newly issued MYGA is backed entirely by new-money assets; there is no existing portfolio to dampen the effect. The portfolio rate buffer only protects in-force blocks where assets were purchased at prior yields.

With top MYGA rates in the market currently ranging from approximately 5.60% on 3-year terms to 6.30% on 7-year terms (from A-rated carriers), the Scenario A rate path could require carriers to reduce new-issue credited rates by 50 bps or accept compressed spreads. In a market where LIMRA reported $34 billion in fixed-rate deferred annuity sales in Q1 2026 alone, that margin decision cascades across a substantial volume of new business.

Stochastic Modeling and the Fat-Tailed Rate Path Problem

Standard credited rate pricing uses scenario-weighted interest rate paths, typically 500 or more deterministic scenarios calibrated to the American Academy of Actuaries’ economic scenario generator (ESG), supplemented by stochastic modeling for tail risk. The scenarios are calibrated to observed Treasury yields and implied volatilities from the swaptions market.

The 8-4 FOMC split creates a specific calibration problem. In a consensus environment (unanimous or near-unanimous votes), the scenario generator produces a distribution of future short rates centered around the market-implied forward curve, with tails that taper smoothly. When the central bank’s own voting members are split between “cut now” and “remove the easing bias,” the implied distribution becomes bimodal: there is meaningful probability mass at both a lower rate path (the Miran view) and a stable-to-higher path (the Hammack-Kashkari-Logan view).

For the pricing actuary running scenario testing, this means the standard single-mode calibration may understate tail risk in both directions. A bimodal generator produces scenarios where:

In the left tail (rates decline 100+ bps), new-money yields drop to 3.0%–3.5% on 5-year IG corporates, squeezing credited rates below competitive thresholds and triggering disintermediation risk as bank CDs and money market funds offer comparable yields
In the right tail (rates rise 50+ bps on inflation repricing), the carrier’s existing portfolio of bonds purchased at lower yields faces mark-to-market losses, and surplus strain intensifies under asset adequacy testing

The practical consequence: pricing actuaries should run supplementary scenarios that explicitly model the bimodal distribution implied by the 8-4 split, rather than relying solely on the unimodal ESG output. This means adding at least two “policy divergence” paths to the standard scenario set and weighting them based on the market-implied probability from fed funds futures.

MYGA Competitive Dynamics at the Rate Peak

The Q1 2026 LIMRA data contextualizes the competitive pressure. Total annuity sales reached $104.6 billion in the first quarter, the tenth consecutive quarter above $100 billion. Fixed-rate deferred annuity sales (the category that includes MYGAs) totaled $34 billion, though this was down 16% year-over-year as some volume shifted to registered index-linked annuities (RILA), which surged 21% to $21.2 billion. Fixed indexed annuity sales declined 4% to $26.6 billion.

The shift from FIA to RILA reflects carrier hedging economics under the current rate regime. FIA crediting strategies rely on the option budget, the portion of the general account earned rate allocated to purchasing index call options. When the earned rate is 5.25% and the guaranteed minimum credited rate is 1.0%, the option budget is approximately 4.25% minus the investment spread. Higher rates provide a larger option budget, enabling more generous caps and participation rates. But the volatility surface has also steepened: the cost of S&P 500 call options for 1-year point-to-point crediting strategies has increased roughly 15–20% since mid-2025, partly driven by geopolitical risk premiums from Middle East tensions.

RILAs sidestep part of this hedging cost problem by transferring a portion of downside risk to the policyholder through buffer or floor structures. The carrier replicates the downside exposure through put spreads rather than purchasing full downside protection, reducing the net hedging cost by 40–60 basis points relative to an equivalent FIA. This cost advantage explains the 21% RILA growth even as FIA sales contracted: product actuaries are allocating option budget more efficiently, and distribution partners are gravitating toward the higher illustrated rates that RILAs can offer.

For MYGA-specific competitive dynamics, the challenge is different. MYGA rates are transparent, easily compared, and directly benchmarked against bank CDs and Treasury yields. A carrier offering a 5-year MYGA at 5.65% when the 5-year Treasury yields 4.10% is paying a 155-basis-point spread to the risk-free rate. If that carrier’s general account earns 5.80% on new-money IG corporates, the implied investment spread is only 15 basis points before expenses. The aggressive rates visible in the market suggest that some carriers are accepting near-zero profit margins on MYGAs to capture assets under management, betting that the liability duration match and renewal rate flexibility will generate margin over the full contract lifecycle.

VM-22 Reserve Adequacy Under Split-Decision Rate Paths

The NAIC Valuation Manual effective January 1, 2026 introduced VM-22 for principle-based reserving of non-variable annuities, applicable prospectively to new business. VM-22 requires insurers to calculate reserves as the greater of a deterministic reserve, a stochastic reserve (if the stochastic exclusion test is not passed), and the floor reserve under the Commissioners Annuity Reserve Valuation Method (CARVM).

For asset adequacy testing under Actuarial Guideline XLIII and the appointed actuary’s annual opinion, the 8-4 split introduces a specific complication. Asset adequacy analysis requires the actuary to demonstrate that the assets backing the annuity liabilities are sufficient to cover all future obligations under a range of interest rate scenarios. The standard approach uses the 16 prescribed economic scenarios in VM-20 (which VM-22 cross-references) plus additional company-specific scenarios that the appointed actuary deems relevant.

The bimodal distribution implied by the FOMC split argues for supplementary scenarios that capture:

Rapid easing (Miran scenario): Funds rate to 3.00%–3.25% by Q4 2026, with new-money reinvestment yields declining 75–100 bps. This stresses the asset side because maturing bonds are reinvested at lower yields, while credited rate guarantees remain locked at the original level. The reserve must hold sufficient assets to cover the negative spread on guaranteed credited rates that exceed reinvestment yields.
Extended hold with inflation repricing (Hammack-Logan scenario): Funds rate stable at 3.50%–3.75% but longer-term yields rise 50+ bps on persistent inflation. This creates mark-to-market losses on the existing bond portfolio. While statutory accounting uses book value for bonds held to maturity, asset adequacy testing must still account for the economic reality of holding depreciated assets against liabilities that may be surrendered.

The C-3 interest rate risk charge in life RBC also depends on the assumed asset-liability duration mismatch. The basic C-3 factor assumes a well-matched portfolio with a 0.125 duration gap. In practice, MYGA blocks are among the most tightly duration-matched liabilities in the general account, because the guaranteed term provides a predictable liability cash flow profile. But the bimodal rate outlook complicates duration management: if the actuary shortens asset duration to protect against rising rates, the portfolio becomes vulnerable to reinvestment risk in the easing scenario, and vice versa.

Disintermediation Risk in a Rate-Peak Environment

Patterns we have seen in prior rate cycles suggest that the current MYGA pricing environment carries meaningful disintermediation risk if rates decline. When a carrier guarantees a 5.65% credited rate for five years and rates subsequently fall, the policyholder has no incentive to surrender; the carrier is locked into a credited rate above new-money yields. The economic loss emerges when maturing assets are reinvested at lower rates while the credited obligation remains fixed.

The reverse scenario is equally problematic. If rates rise, policyholders may surrender their existing MYGA (accepting any market value adjustment) to capture higher rates at a competitor. Oliver Wyman research has documented elevated fixed annuity lapses during the 2022–2024 rate-rising period, with dynamic lapse functions tracking the differential between market rates and credited rates.

The 8-4 split forces pricing actuaries to model both tails simultaneously. The market value adjustment (MVA) provides partial protection against rising-rate surrenders, but MVA formulas vary by product and jurisdiction, and consumer regulators in several states have pushed back on aggressive MVA structures. For the declining-rate scenario, the carrier’s protection is the investment spread cushion and the ability to invest at above-guarantee yields before rates drop, which depends on how quickly the easing cycle materializes.

Reinvestment Rate Assumptions and the Yield Curve Shape

The current yield curve shape provides one structural advantage for MYGA pricing. With the 10-year Treasury at approximately 4.46% and the fed funds rate at 3.50%–3.75%, the curve is positively sloped by roughly 70–95 basis points in the 5-to-10-year segment. This positive slope means that a carrier backing a 5-year MYGA with 7-year corporate bonds captures an incremental roll-down benefit as the bonds age and approach maturity.

The reinvestment rate assumption is the single most sensitive input in the MYGA pricing model. A 25-basis-point change in the assumed reinvestment rate over a 5-year horizon shifts the present value of the investment spread by approximately 8–12 basis points per year, depending on the portfolio turnover rate and duration matching precision. For a $1 billion MYGA block, that translates to $4–6 million in annual investment income variance.

With LIMRA projecting annuity sales above $450 billion for full-year 2026 and demographic demand from 4.1 million Americans turning 65 annually, the volume of new MYGA liabilities being priced under this bifurcated rate outlook is substantial. The carriers that navigate the credited rate floor decision most effectively will be those whose pricing actuaries incorporate the bimodal rate path explicitly rather than anchoring to a single consensus forecast that the FOMC itself has shown cannot command a majority.

Why This Matters for Pricing Actuaries

The 8-4 FOMC split is not a transient headline. It signals that the distribution of future short-rate paths feeding into credited rate models has widened materially, and that the standard approach of calibrating to a unimodal forward curve understates the real uncertainty facing general account portfolios. Pricing actuaries setting credited rate floors on MYGA and fixed deferred products should consider three adjustments:

Run bimodal scenario overlays that explicitly model the Miran (easing) and Hammack-Kashkari-Logan (hold/hawkish) paths as separate probability-weighted branches, rather than blending them into a single mean-reverting path.
Stress the investment spread target under both rate trajectories. A 150 bps spread that works under Scenario B may be unsustainable under Scenario A if new-money yields drop 75–100 bps within 12 months.
Re-examine the MVA formula for adequacy against rising-rate surrenders while simultaneously ensuring that the credited rate floor remains competitive under declining-rate assumptions. The asymmetric risk profile of a MYGA guarantee demands that both tails receive explicit attention in the pricing model.

The last time the FOMC split 8-4 was October 1992. In the three years that followed, the funds rate moved from 3.00% to 6.00% and back to 5.25%, a swing that tested every credited rate assumption in the industry. The 2026 pricing environment may not follow the same trajectory, but the uncertainty embedded in the vote split demands that actuarial models account for the full range of outcomes.
