Why Ethereum Turned Inflationary Again

Ethereum has not adopted a permanently inflationary supply policy. ETH’s supply is the result of two forces moving in opposite directions: new ETH issued as validator rewards and ETH burned through EIP-1559 transaction fees. When issuance is higher, supply grows; when burn is higher, supply falls. 4

That balance tilted toward issuance in the seven-day period ending August 29, 2026. Reported figures show 20,515.08 ETH issued to validators and 389.76 ETH burned, producing a net increase of 20,125.33 ETH. 2

The immediate cause: low fees mean less ETH burned

EIP-1559 burns the base fee paid for Ethereum transactions. The burn therefore depends on demand for Ethereum blockspace: when the network is busy and base fees rise, more ETH is destroyed; when activity and fees fall, the burn slows. Validator rewards, meanwhile, continue under proof-of-stake. 4

This makes ETH’s supply “demand-responsive.” A quiet period can be inflationary without any change to the protocol’s issuance rules, while a surge in high-value on-chain activity can restore net deflation.

The latest increase is economically modest. Against a total supply above 120 million ETH, 20,125 ETH represents roughly 0.016% for the measured week. 23 That number should not be annualized as though one week’s conditions will persist. Its more useful signal is that paid demand for Ethereum’s Layer 1 blockspace was not high enough during that window to offset validator issuance.

How Dencun changed the fee-and-burn equation

The Dencun upgrade introduced EIP-4844, which gave rollups a cheaper way to publish data through blob transactions. That lowered Layer-2 costs and improved Ethereum’s scalability, but it also reduced the pressure on users and rollups to compete for conventional Layer 1 blockspace.

The result is a trade-off for ETH economics: cheaper transactions are good for users and can support broader adoption, but lower mainnet fees generally create less EIP-1559 burn. Contemporary reporting found average Ethereum transaction fees fell about fourfold after Dencun, alongside a return to net issuance. 39

Layer-2 growth does not automatically translate into higher Layer 1 burn. The key question is how much activity ultimately creates demand for scarce, fee-paying Ethereum blockspace rather than simply increasing transaction counts on cheaper execution layers.

The broader post-Merge trend

The Merge eliminated execution-layer issuance and materially reduced Ethereum’s rate of new ETH creation. Ethereum.org describes the remaining post-Merge issuance as consensus-layer rewards for validators, with the change reducing total issuance substantially compared with proof-of-work. 20

That reduction did not guarantee permanent deflation. Reports citing supply trackers say circulating supply had risen by roughly 950,000 ETH since the Merge, with an annualized inflation rate of about 0.23% at the time of measurement. 17 Tracker readings and measurement windows differ, so the precise cumulative figure should be treated as an estimate rather than a single immutable ledger statistic.

The pattern was visible after Dencun in 2024. One report described nearly 50,000 ETH added during a roughly 72-day inflationary stretch, while other reports for overlapping periods cited more than 112,000 ETH added since mid-April. 2538 Those figures use different windows and trackers; they should not be combined as if they measured the same interval. The underlying mechanism, however, was consistent: cheaper data and lower fees reduced burn faster than validator issuance declined.

Can Ethereum become deflationary again?

Yes. Deflation does not require a new issuance policy if fee-paying demand rises enough. Higher-value DeFi activity, NFT activity, stablecoin settlement, or other applications using Ethereum’s Layer 1 could lift gas prices and increase the amount of ETH burned.

The more important metric is therefore not transaction count alone. Observers should track:

• Ethereum Layer 1 base fees and gas used
• EIP-1559 burn relative to validator issuance
• Blob demand and rollup data economics
• Whether Layer-2 growth generates more settlement and data demand on Layer 1
• The amount of ETH staked and the resulting validator issuance
• The mix and economic value of on-chain activity

If Layer 2s continue to become more efficient without creating comparable demand for scarce Layer 1 blockspace, net issuance could persist. If Ethereum experiences another period of sustained, fee-intensive activity, burn could again exceed issuance.

What EIP-8363 would change

A draft proposal called EIP-8363, “Tapered Issuance Burn,” would burn an increasing share of validator rewards as the proportion of ETH staked rises. The proposal’s burn fraction would reach 100% at a fixed saturation balance representing roughly half of ETH’s supply, causing the covered consensus-layer issuance to approach zero at that threshold. 58

This is a proposal, not an adopted Ethereum rule. Its parameters, implementation and effect on staking incentives remain uncertain. If pursued, it would address the issuance side of the equation rather than relying only on higher transaction fees to support ETH scarcity.

What the latest increase means for ETH holders

The one-week increase is too small and too short-lived to establish a major change in ETH’s long-term economics. It does, however, challenge the idea that “ultrasound money” is an automatic consequence of proof-of-stake. Ethereum’s post-Merge supply is better understood as conditional: validator issuance is ongoing, while the deflationary force of EIP-1559 depends on real demand for fee-paying blockspace.

ETH was reported down about 2.5% over the preceding 24 hours in the same market snapshot, but a one-day price move does not demonstrate that the supply increase caused the decline. 2 The durable question is whether low fees and low burn persist—and whether future network demand grows faster than Ethereum’s increasingly efficient Layer-2 infrastructure.
