Solana has officially enacted SIMD-0411, a major monetary policy update designed to accelerate the chain’s disinflation schedule and reduce long-term supply expansion. The proposal went live following confirmation from Helius co-founder and CEO Mert Mumtaz, marking one of the most significant economic updates to Solana’s token model since launch.
Accelerating the Path to 1.5% Inflation
SIMD-0411 focuses on speeding up Solana’s transition toward its terminal 1.5% annual inflation rate. Previously expected to take six years, the new schedule reduces that time frame to roughly three years, effectively doubling the pace of disinflation across the network.

The update increases the annual disinflation rate from –15% to –30%, allowing the ecosystem to reach its long-term target more efficiently while maintaining simplicity in Solana’s architecture, no added mechanisms, no reward cuts, and no structural redesign.
A visual projection shared by SolanaFloor illustrates the impact: the accelerated schedule removes an estimated 22.3 million SOL of potential issuance over the six-year horizon.
Supply Growth and Staking Yield Implications
The new policy is projected to reduce total SOL supply growth by 3.2% over six years, effectively curbing millions of tokens from entering circulation. While this improves the asset’s long-term scarcity profile, it also influences staking rewards:
- Year-one yields remain near current levels
- By year three, staking rewards may decline from ~6.41% to ~2.42% (assuming 66% staking participation)
These adjustments reflect a shift toward more sustainable validator incentives supported increasingly by transaction feesrather than inflationary issuance.
Economic Rationale and Ecosystem Alignment
Developers and ecosystem contributors argue that Solana’s rapidly growing economic activity, including record transaction throughput, rising DeFi usage, and high validator participation, justifies a more mature monetary policy.
The intention is to make SOL more scarce, improve capital efficiency, and align long-term incentives across validators, stakers, and users without introducing complexity or compromising performance.
A Successful Follow-Up to Earlier Attempts
SIMD-0411 follows the earlier SIMD-228 proposal, which failed to reach consensus in March 2025. This time, the community alignment was strong enough for activation, signaling broad support for a refined tokenomics model.
With SIMD-0411 now live, Solana enters a new phase of supply management that aims to strengthen investor confidence, improve monetary predictability, and support long-term network sustainability.
