Ethereum is working through a serious structural debate about its staking reward model, with asset manager Grayscale publishing research that explicitly backs proposals to cap how much validators can earn above certain staking thresholds, arguing the change would be “positive for the price of ETH” over time.
The report, authored by Grayscale’s Head of Research Zach Pandl, identifies two compounding problems that have quietly shifted Ethereum from a deflationary to an inflationary token since its peak burning period.
The first issue is the collapse in Layer 1 transaction fee revenues. As more activity has migrated to cheaper Layer 2 networks, the base fee burned on every Ethereum transaction has declined substantially. Annual gross inflation now sits at approximately 1 million ETH, with the token burn rate failing to keep pace. The second structural problem is that the marginal cost of staking ETH has fallen to near zero. When Ethereum first introduced proof-of-stake, staked assets were locked with no withdrawal option, imposing a genuine liquidity premium on validators. With withdrawals now enabled and liquid staking tokens, ETFs, and corporate treasury vehicles all competing to stake at minimal cost, that risk premium has essentially disappeared. The consequence, Pandl warns, is that if current incentives persist, virtually all ETH could eventually end up staked, creating unnecessary dilution and dangerous centralisation risk if a handful of large validators control the majority of staked supply.
The Ethereum community is currently discussing proposals including EIP-7917, which would introduce tiered or capped reward curves. Under these models, validators staking beyond a defined threshold would receive diminishing or zero additional rewards, structurally reducing the incentive to over-stake. Grayscale’s research points out that capping issuance above certain staking ratios would slow supply growth and enhance ETH’s scarcity characteristics. The firm draws an analogy to commodity markets, where constrained production typically supports long-term prices. A record 32% of all ETH is currently staked, with the base staking yield sitting at approximately 3.0-3.2%, down roughly 40% from levels above 5% in late 2022.
As of Friday morning, ETH is trading at approximately $2,255, up around 1.4% over the past 24 hours and maintaining a market capitalisation of roughly $272 billion. Whale wallets have been accumulating heavily in recent sessions, with on-chain data indicating purchases of over 140,000 ETH in a 96-hour window earlier this month. The upcoming Glamsterdam upgrade, targeting June 2026, is expected to significantly increase Layer 1 throughput and is viewed by some analysts as a catalyst that has not yet been fully priced into the market. Whether the staking reward debate ultimately results in a protocol change will depend on community consensus, a process that on Ethereum tends to move slowly, though Grayscale’s public backing adds weight to the reformist camp.
