Helius has proposed a significant adjustment to Solana's inflation policy through SIMD-550, suggesting an increase in the deflationary rate from -15% to -30%. This change aims to accelerate the achievement of Solana's long-term inflation target of 1.5%, reducing the timeline from 5.7 years to 2.8 years. According to Helius's modeling, this proposal could decrease SOL issuance by approximately 18.89 million tokens over the next six years, translating to a reduction of about $1.51 billion at current market prices. The proposal is part of ongoing efforts to enhance Solana's economic model and token value.
