Solana Weighs Major Economic Shift to Curb SOL Issuance

The governance votes, SGP-0002 and SGP-0003, center on technical frameworks SIMD-0550 and SIMD-0553. The first proposal seeks to double the annual disinflation rate from 15% to 30%. By accelerating the decline toward the network's 1.5% terminal floor, the protocol would reach this limit by early 2029 rather than 2032. Analysts at 21Shares estimate this could equate to a reduction in issuance valued between $1.4 billion and $1.5 billion, depending on market fluctuations.

While the prospect of a tighter supply cap appeals to some, it has sparked division among institutional stakeholders. Solana Company, which relies heavily on staking rewards for its quarterly revenue, has opposed the measures, citing concerns over the predictability of institutional returns. Projections suggest that nominal staking yields could drop from 5.25% to 2.25% by the third year of implementation.

Simultaneously, SIMD-0553 aims to overhaul transaction fee structures. By introducing a new resource-based fee component that is burned rather than distributed to validators, the proposal could increase daily SOL destruction by up to fourteenfold, based on current network activity. Despite the scope of these proposals, approval would serve as a governance mandate rather than an immediate change. Developers would still face a lengthy process of code implementation, testing, and staged feature activation before the new economic parameters take effect on the mainnet.
