Solana Validators Approve SIMD-0550 to Double Annual Disinflation Rate

Solana validators approved SIMD-0550 on a 67.001 percent vote, clearing the 66.667 percent supermajority threshold by the narrowest margin.

The measure doubles the annual disinflation rate from 15 percent to 30 percent, moving the network to its 1.5 percent terminal inflation rate in H1 2029 rather than H1 2032.

The change reduces new SOL issuance by 18.9 million tokens over six years compared with the prior schedule.

The official Solana account posted the results on X on 28 August 2026.

Open questions

Projected nominal staking yields fall from approximately 5.84 percent to 4.34 percent.

It remains unknown whether growth in transaction-fee revenue will offset the lower inflation rewards for validators.
