Solana Considers Major Supply Adjustments
Solana validators are currently voting on two supply proposals that could reduce projected emissions by approximately $1.4 billion to $1.5 billion over six years. Currently, Solana's staking yield is around 5.25%, with the majority driven by protocol inflation of about 3.78%, while transaction fees and maximal extractable value supply the remainder.
The first proposal, SGP-0002 (corresponding to SIMD-0550), focuses on reducing the inflation schedule by doubling Solana's annual disinflation rate from -15% to -30%. According to data from 21Shares, this change would compress the timeline to Solana's 1.5% terminal inflation rate from roughly 5.7 years down to 2.8 years, reaching that level by the first half of 2029 instead of 2032. Under this plan, nominal staking yields would fall to approximately 4.34% in the first year, 3% in the second year, and 2.25% in the third year.
The second proposal, SGP-0003 (based on SIMD-0553), aims to divide the current signature fee into a base inclusion fee paid to block leaders and a resource fee determined by requested compute units that would be permanently burned. At current network activity levels, this change would increase daily SOL burns from roughly 600–800 SOL to about 7,500–9,000 SOL. Voting on these measures is scheduled to continue through epoch 1023.
Historical Precedents and Market Impact
To gauge potential market reactions, 21Shares analyzed previous upgrades on other protocols. Cosmos implemented Proposal 848 to cut maximum inflation in November 2023, after which ATOM gained 25% over the following month and 10% over three months, though the period coincided with optimism around spot Bitcoin exchange-traded funds. Similarly, Ethereum introduced its EIP-1559 burn mechanism in August 2021, and ETH climbed 37% in one month and 60% over three months during a broader market rally approaching a cycle peak.
Analysts note that while supply-reduction upgrades can strengthen a token's narrative, broader macroeconomic and market conditions historically exert a larger influence on price movements over longer horizons. Neither of the current Solana proposals alters the protocol immediately; approval would grant developers a mandate, leaving the technical work and activation timing to be finalized.
