Solana Governance Proposals Set to Slash Token Supply

The Solana (SOL) ecosystem is poised to undergo significant changes in its token supply dynamics, thanks to two governance proposals that are currently being considered.

According to an assessment by 21Shares, if both proposals - SIMD-550 and SIMD-553 - are implemented together, the total SOL issuance over a six-year period could decrease by approximately $1.4 billion to $1.5 billion.

SIMD-550 aims to increase Solana's annual rate of inflation reduction from 15% to 30%, which would bring forward the network's long-term target of achieving a final inflation rate of 1.5% from around 2032 to the first half of 2029.

However, this faster decline in SOL issuance would also lead to a decrease in staking yields, with estimated nominal staking yields falling to around 2.25% in the third year of the new model's implementation.
