Solana proposals could cut $1.5B in SOL issuance, halving staking yield

Solana voters are weighing two proposals that could cut SOL issuance by $1.5 billion over six years while halving staking yields, per 21Shares.

The pair of Solana Improvement Documents — SIMD-550, filed by infrastructure firm Helius, and SIMD-553, submitted by research shop Temporal — would together reduce net token issuance by $1.4 billion to $1.5 billion over six years, according to 21Shares' Aug. 24 analysis.

SIMD-550 doubles the network's annual disinflation rate to 30 percent from 15 percent, pulling the 1.5 percent terminal inflation floor forward to the first half of 2029 from roughly 2032. SIMD-553, approved and merged into the codebase July 20, introduces a burn fee tied to compute units used in financial transactions. Daily SOL burns could climb from about 600 to 800 SOL today to between 7,500 and 9,000 SOL, equal to $712,500 to $855,000 in daily value as of Aug. 24.

The yield compression is the trade-off. Nominal staking yield, now near 5.25 percent, would fall to about 4.34 percent in year one and near 2.25 percent by year three, per 21Shares. Solana's staking ratio of 67.93 percent runs nearly double Ethereum's 34.14 percent, leaving room for capital to rotate into Solana DeFi. Voting on both proposals runs through Aug. 29, with each tallied separately.

Validator Economics Face a Squeeze

Under current projections, two of Solana's 738 validators would turn unprofitable in year one, a figure that could climb to 30 by year three if fees rise as expected. Protocol inflation, the largest share of staking income at roughly 3.78 percent, would shrink fastest under the faster disinflation curve. The vote split may mirror March 2025's SIMD-0228, which won 61.4 percent of ballots but fell short of the two-thirds supermajority needed to advance, with smaller validators opposing the pay cut.

Comparable supply-side changes have historically lifted token prices. Ethereum's EIP-1559 burn mechanism gained 37 percent in the month after its August 2021 launch, while Cosmos's Proposal 848 rose 25 percent in the month following its November 2023 passage. Both moves coincided with broader market strength, so the upgrades were not the only driver. SOL traded at $101.31, up 4.23 percent, as of the latest session.

The outcome hinges on whether SIMD-550 clears its vote and validators finalize SIMD-553's fee design, which remains unresolved. If both pass, lower staking income could push capital out of staking and into Solana DeFi, where usage and fee revenue would need to offset weaker yields. For holders, the reforms read as a long-term supply improvement rather than a simple yield cut.
