Solana opens vote to double disinflation, cutting 18.9M SOL issuance

Solana's first governance cycle puts a supply-side test before validators and stakers: whether to double the pace at which new SOL issuance declines.

Solana opened an on-chain vote Aug. 23 on SGP-0002, doubling annual disinflation to 30 percent and cutting projected six-year issuance by 18.9 million SOL.

The proposal, linked to SIMD-0550 authored by Lostin and 0xIchigo of Helius, would accelerate how quickly new SOL issuance declines without changing the network's 1.5 percent inflation floor. "Changing the schedule would introduce uncertainty into multi-year financial models," Joseph Chee, chairman and CEO of Solana Company, said in opposing the proposal.

Under the current 15 percent annual disinflation schedule, inflation would fall to about 3.24 percent after one year and reach the 1.5 percent floor around the first half of 2032. The proposed 30 percent schedule would cut inflation to roughly 2.86 percent after one year and reach the same floor around early 2029, reducing cumulative supply to 708.54 million SOL after six years versus 727.43 million under the current schedule — a difference worth about $1.81 billion at $95.70 per SOL on Aug. 23.

The vote tests both monetary policy and the network's new stake-weighted governance framework, which requires at least one-third of network stake to participate and two-thirds of participating stake to vote in favor. A successful vote would not immediately change issuance rules — developers would still need to complete the associated Solana Improvement Document and deploy the change through a feature gate.

Lower issuance would also reduce staking rewards. At 68 percent modeled staking participation, nominal yield would fall from about 5.84 percent currently to 4.34 percent after one year, then to roughly 3.00 percent after two years and 2.25 percent after three years, excluding commissions, MEV and block-related revenue.

Validator economics weaken gradually. Among 738 validators, two additional operators become unprofitable or move from breakeven after one year, rising to 13 after two years and 30 after three years, according to the authors' model.

Institutional opposition tests the first governance cycle

The economics have already drawn institutional opposition. Nasdaq-listed Solana Company said Aug. 21 it would vote against SGP-0002, arguing that changing established economics during the first governance cycle could reduce institutional predictability. Staking generated $2.512 million of the company's $2.526 million in second-quarter revenue, making the yield issue material to its own accounts. HSDT shares rose 12.10 percent to $2.0850 as the company disclosed its positions.

The vote follows the failed SIMD-228 debate in 2025, which sought dynamic issuance tied to staking participation. About 74 percent of staked SOL participated, but only 61.4 percent of non-abstaining votes supported the proposal, below the required two-thirds threshold.

Under the new SGP process, at least one-third of network stake must participate, and two-thirds of participating stake must vote in favor for passage. SGP-0002 therefore places two questions before the network: how quickly SOL dilution should decline, and whether governance can produce decisive consensus.

The outcome will shape Solana's supply trajectory for years. If approved, the faster disinflation schedule would tighten SOL supply by roughly 2.6 percent of projected six-year supply, reducing sell pressure from inflation. But lower staking yields could weigh on validator economics and institutional staking products — Bitwise's Solana Staking ETF held 8.18 million SOL worth $622.02 million as of Aug. 9, with 99 percent of tokens staked and a 5.84 percent net annualized reward rate.
