Key Takeaways:
SOL issuance could fall by $1.4 billion to $1.5 billion over six years under two Solana proposals that would halve staking yield to 2.25 percent.
The projections come from 21Shares, which analyzed the two proposals now advancing through Solana's formal governance process. The asset manager said the yield reduction is designed in part to redirect capital from staking into productive on-chain activity, with Solana's staking ratio at 67.93 percent nearly double Ethereum's 34.14 percent.
SIMD-550, proposed by infrastructure firm Helius, doubles the network's annual disinflation rate from 15 percent to 30 percent, moving Solana's path to its 1.5 percent terminal inflation rate from around 2032 to the first half of 2029. SIMD-553, submitted by research firm Temporal and merged on July 20, introduces a burn fee on compute units used in financial transactions. Daily SOL burns could climb from roughly 600 to 800 SOL to between 7,500 and 9,000 SOL, equivalent to $712,500 to $855,000 per day as of August 24.
Nominal staking yield could fall from approximately 5.25 percent to 4.34 percent in year one, 3 percent in year two, and 2.25 percent by year three. Validator economics face additional pressure, with two of 738 validators projected to turn unprofitable in year one, rising to 30 by year three. SIMD-550's vote has been ongoing since August 23, and both proposals require a two-thirds supermajority of staked SOL to pass.
Solana's staking yield of approximately 5.25 percent draws from three sources: protocol inflation at roughly 3.78 percent, transaction base fees and priority tips, and maximal extractable value (MEV) contributing about 2 percent. SIMD-550 targets the inflation component, while SIMD-553 adds a new burn mechanism.
The burn fee under SIMD-553 applies to compute units requested during financial operations. At current network activity, daily burns would rise roughly tenfold, though 21Shares noted this level would not fully offset daily inflation of approximately $4.5 million.
The final design of validator voting fees under SIMD-553 remains unresolved, with costs potentially rising modestly or by as much as 21 times. This uncertainty compounds the yield compression from SIMD-550, squeezing validator profitability at the same time.
Ethereum's EIP-1559 burn mechanism, introduced in August 2021, coincided with gains of 37 percent over one month and 60 percent over three months, though that window overlapped with the cycle's market top. Cosmos's Proposal 848, which halved maximum inflation in November 2023, produced gains of 25 percent over one month and 10 percent over three months during anticipation around Bitcoin ETF approvals.
21Shares cautioned that external market conditions influenced both outcomes. The firm noted that MEV and tips are expected to become primary revenue sources for stakers over the long term, though they would need to rise roughly 55 to 95 percent to fully compensate for the yield loss.
Solana holds a leading share in tokenized equities and has settled over 22 percent of stablecoin transactions in 2026 while hosting only 5 percent of global stablecoin supply, a signal of network efficiency and headroom for growth.
