Key Takeaways
- •Solana implements SIMD-0411 to fast-track the decrease in network inflation.
- •It cuts the timeline to reach 1.5 percent inflation from six years to three.
- •Supply emissions would fall by 22.3 million SOL during the next six years.
Inflation Reduction Proposal
A proposal, dubbed SIMD-0411, has been put forward by Solana developers that would double the disinflation rate of the network from -15% to -30%. This change will help decrease inflation more aggressively while retaining the 1.5% long-term target. Since only one parameter changes, it remains a simple, low-risk update for core protocol operations.
Under the current curve, Solana inflation declines gradually from 4.18% and requires 6.2 years to reach the 1.5% terminal rate. SIMD-0411 cuts this timeline down to 3.1 years, effectively halving the transition period. In the view of developers, the approach is predictable and easy to communicate across a set of stakeholders that includes retail and institutional stakers.
Modeling included in the proposal shows that the accelerated decline provides more certainty around issuance without abrupt policy shocks. The proposal is currently under review and would activate after a governance period and the Alpenglow update.
Projected Supply Reduction and Emission Impact
| Period | Current (-15%) Supply | Proposed (-30%) Supply | Difference (SOL) | Difference (%) |
|---|---|---|---|---|
| Current (mid Nov 2025) | 613,823,198 | 613,823,198 | 0 | 0% |
| After 1 year | 638,226,790 | 637,661,546 | 565,243.98 | 0.09% |
| After 2 years | 659,812,163 | 655,389,900 | 4,422,263.36 | 0.67% |
| After 3 years | 678,584,933 | 667,958,800 | 10,626,133.08 | 1.60% |
| After 4 years | 695,015,051 | 678,245,313 | 16,769,737.54 | 2.47% |
| After 5 years | 709,181,881 | 688,610,002 | 20,571,879.01 | 2.99% |
| After 6 years | 721,490,711 | 699,191,341 | 22,299,369.53 | 3.20% |
Under the new parameters, supply growth for Solana would notably slow down. Modeling shows that after six years, total supply under the new curve reaches 699.19 million SOL, compared to 721.49 million SOL under the current schedule. This represents a reduction of 22.3 million SOL, or 3.2%, over the modelled horizon.
This reduction, at recent market valuations, is worth about $2.9 billion in avoided emissions. The adjustment diminishes the sell pressure coming from staking rewards, particularly for those participants who liquidate their rewards to pay taxes. As analysts explained, even modest cuts to issuance can greatly reduce the dilution faced by network participants in the long term.
Due to the nature of Solana's burn mechanics, there is minimal influence on net issuance following SIMD-0096. In essence, the disinflation change would be the primary adjustment affecting supply. The proposal positions emission control as a long-term economic priority for the network.
Expected Effects on Staking Yields and Validator Economics
With inflation falling faster, nominal staking yields decrease over the three-year period. Using a 66% staking participation rate, the modeled yields decline from 6.41% today to 5.04% after one year, 3.48% after two years, and 2.42% after three years. For participants whose rewards streams are dependent on staking income, yield declines are gradual but evident.
Validator profitability would shift as well, as rewards decline. SIMD-0411 modeling shows 10 validators moving into unprofitable positions in year one, 27 in year two, and 47 in year three. Beyond year three, inflation reaches the 1.5% terminal rate and stabilizes. Most validators outside the supermajority already rely minimally on inflation commissions.
The proposal recognizes that lower nominal yields might reduce the attractiveness of SOL to a certain set of investors who are viewing the asset as a yield-bearing instrument, but it also argues that controlled issuance underpins more accurate economic signals and reduces unnecessary dilution.
Community Considerations and Economic Alignment
The proposal frames disinflation reform as one step toward predictable monetary policy within the Solana ecosystem. The authors underline that the shift does not close the door on adopting dynamic issuance models in the future but presents a near-term improvement with minimal implementation complexity. Adjustments to emission were debated within SIMD-228, which did not pass governance thresholds.
SIMD-0411 is framed as a balancing measure-reducing issuance, but in a way that does not create sudden shocks. The six-month activation buffer allows a period of time for validators and stakers to adjust to the changed expected yield.
The simplified approach also minimizes governance load and communication overhead from stakeholders. This proposal remains under evaluation pending governance procedures. As review progresses, community members are weighing trade-offs between reduced dilution, long-term economic sustainability, and the impact on validator participation.
