Per Woofun AI, Helius researchers have submitted SIMD-550, a proposal to modify Solana's inflation mechanism by increasing the anti-inflation rate from -15% to -30%. This adjustment doubles the speed of inflation decline, targeting the long-term 1.5% rate within 2.8 years by mid-2029, rather than the current 5.7-year timeline extending to mid-2032.

The model projects this shift will reduce the issuance of 18.89 million SOL over six years, equating to approximately $1.51 billion.

Concurrently, nominal stakeholder yields are expected to decrease from 5.84% to 2.25% over three years. While the impact on profitable validators is limited, with only 45 validators potentially moving to losses over three years, SIMD-550 serves as an updated iteration of the postponed SIMD-411, aligning with broader economic improvements like SIMD-553 and the Alpenglow Validator Admission Ticket.
