Solana governance proposals SIMD-550 and SIMD-553 would accelerate SOL deflation by doubling disinflation and adding compute unit burn fees, potentially reducing issuance by $1.4B-$1.5B over six years.

Two Solana governance proposals aim to accelerate the network's path toward a lower inflation equilibrium. SIMD-550 proposes to double the annual disinflation rate to -30%, which would shift the timeline to reach Solana's long-term 1.5% inflation target from approximately 2032 into the first half of 2029. Under this scenario, staking rewards are expected to decline to around 2.25% within three years. SIMD-553 was approved and integrated on July 20, introducing a mechanism that burns SOL based on compute unit usage from financial transactions.
The compute unit burn mechanism substantially amplifies token removal. Current daily burns of roughly 600–800 SOL could expand to between 7,500 and 9,000 SOL per day depending on network load. Combined, the two proposals would cut total issuance by approximately $1.4B–$1.5B over a six-year span.
The full economic effect remains contingent on two variables: approval of the SIMD-550 disinflation acceleration, and the specific fee structure validators will implement under SIMD-553. Neither outcome is yet certain.
