Grayscale's Staking ETFs Prompt Ethereum and Solana to Consider Yield Reductions

Grayscale's filings with the SEC on July 17 announced that its Ethereum and Solana staking ETFs would convert staking rewards into cash, distributing them to shareholders at least quarterly, with changes expected around August 7. In response, both Ethereum and Solana are considering adjustments to their protocols that would lower staking yields.

Solana developers are proposing to accelerate disinflation, aiming to reduce the modeled staking yield from 5.84% today to 2.25% over the next three years. Their SIMD-0550 proposal would double the network's annual disinflation rate from 15% to 30%, resulting in 18.9 million fewer SOL entering circulation over six years, valued at approximately $1.47 billion at current prices.

Meanwhile, Ethereum researchers have drafted EIP-8363, which would burn an increasing share of validator rewards as the staking ratio rises, potentially reaching a 100% burn rate once half of ETH's supply is staked. This could significantly impact staking yields and the overall issuance of ETH.

Both proposals aim to create a tighter supply narrative and reduce the dilution for non-staking holders. However, they also raise concerns about the impact on validators and the broader DeFi ecosystem, as lower yields could affect the attractiveness of staking compared to other DeFi activities.

As these changes are discussed, the economic implications for both Ethereum and Solana are being closely monitored, particularly in how they may influence investor behavior and market dynamics.
