EIP-8363 Quantitative Review: What Does Ethereum Want to Regain by Cutting Staking 'Subsidies'?

EIP-8363 attempts to adjust ETH supply by destroying staking rewards, triggering intense competition between security and redistribution of benefits.

Written by: Mario Chow, IOSG

The EIP-8363 proposal suggests that as the staking rate increases, an ever-growing portion of validator rewards should be destroyed, reaching 100% destruction when 50% of the supply is staked. This article models its impact on issuance, yield, and staking equilibrium; examines whether ETH's yield truly explains its price; quantifies how much of the on-chain economy genuinely relies on this yield; and provides our conclusions.

All calculations are based on on-chain data and the original EIP text. The model is independently constructed, aligning with publicly available third-party data within 2%. Data is updated to August 24, 2026.

One-Sentence Version of the Argument

The fee destruction mechanism is already dead, making issuance the only lever Ethereum still holds over ETH supply. This proposal halves the issuance at current staking levels rather than bringing it to zero; moreover, it is self-limiting: under any reasonable yield threshold for stakers, the system will ultimately stabilize with 26-34% of the supply staked and an issuance of 0.3-0.5% per year. Meanwhile, the yield it reduces shows no detectable relationship with ETH prices.

The Destruction Mechanism is No Longer Effective

EIP-1559 destroyed 1.48 million ETH in 2022. EIP-1559 destroys the base fee, which is essentially congestion pricing; once blobs move rollup data off L1 and gas limits are raised, congestion disappears: gas usage doubles, while the average base fee drops by 96%, leading to a 98% decline in destruction volume since 2022. Over the past twelve months, it has destroyed a total of 25,660 ETH, with the recent 30-day running rate even lower: 39 ETH per day, annualized to about 14,300 ETH.

▲ Daily fee destruction volume of EIP-1559 changes by year: from 8,844 ETH per day in 2021 to 57 ETH per day in 2026------far below the current issuance curve and well below the maximum issuance curve under EIP-8363.

Compared to a total issuance of about 1.08 million ETH per year, destruction currently offsets only 2.4% of new supply. As a mechanism, "ultrasound money" is effectively over. L2 migration and blob expansion have moved the fee base off L1: during the same period, L1 gas usage actually doubled (from 3.4 billion to 6.7 billion units), while the average base fee dropped from 4.00 gwei to 0.17 gwei: thus, this is a price effect, not a demand effect.

Net Issuance: What Has Happened to Supply?

Destruction is only half of the ledger. When viewed alongside issuance, the picture becomes more severe: issuance has never stopped growing, while the offset has directly disappeared beneath it.

▲ Comparison of ETH minted on the consensus layer monthly since the merge versus ETH destroyed by EIP-1559. Issuance bars steadily grow; destruction bars nearly shrink to zero by 2025.

In the 47 months since the merge, only 13 months have been deflationary: the last being March 2024. ETH has been in a state of inflation for 28 consecutive months, and this rate has roughly tripled during this period, from +0.26% per year to +0.87% per year. The reason is not how much issuance has increased (only 4% since 2024), but that the offset has gone to zero.

This reconstructs the entire debate. EIP-8363 is often said to be a choice between staking yield and monetary scarcity. However, a more accurate understanding is much narrower and more forced: the issuance policy is now the only lever Ethereum has left over ETH supply, as the demand-driven one is no longer functioning. Regardless of legislation, all supply issues must now pass through the issuance curve.

What Exactly Does EIP-8363 Do?

Before dissecting the mechanism, we need to clarify the core motivation of the officials: to safeguard network security. The proposal's authors believe that once the overall staking rate crosses the 50% threshold, Ethereum will lose its ability for "social layer defense" and face systemic parasitic risks too big to fail from LST oligarchs. Therefore, this proposal attempts to lock in the staking cap through mandatory interest rate cuts. However, grand security philosophies often obscure the real flesh and blood on the ledger. Setting aside metaphysical debates about decentralization, what does this mechanism truly mean in the real on-chain economy? Here are purely quantitative deductions.

How is Money Deducted? (Core Mechanism)

• First earn, then deduct: Validators initially earn the full rewards for their tasks, but then the system will directly "burn" a portion of the rewards at a ratio (assumed to be b).
• Deduct based on "theoretical full score" without double punishment: The key here is that the system calculates the destruction amount based on the full rewards you theoretically should receive, not based on the actual rewards you receive. Why do this? Because if you accidentally go offline, you wouldn't earn rewards anyway; if the system deducts based on your actual situation, it would be too unfair to those who are offline. By deducting based on "theoretical values," it ensures that everyone's motivation to work remains unchanged, and offline individuals are not punished twice.
• Extreme situation protection: If the Ethereum network encounters serious issues (entering inactivity leak state), the destruction of rewards for proof will be paused.
• Snapshot taken externally: This proposal only affects consensus layer rewards. The "extra income" you earn from running a node, namely MEV and Priority Fees, will not be affected at all.

Two Common Misunderstandings in the Community

Misunderstanding 1: "Ethereum's issuance will be directly cut to zero"

Truth: Not at all. The current staking amount is about 42.2 million ETH, and at this level, the destruction ratio b is 58.6%.

If issuance is to be completely cut to zero, the staking amount would need to soar to 60.25 million ETH (43% higher than now). So the accurate statement should be: this proposal at this stage only cuts issuance by about half, and it is still far from completely reaching zero.

Misunderstanding 2: "Yields will plummet instantly, triggering a DeFi collapse on the first day"

Truth: The officials designed an 18-month "soft landing" period, making the first day almost imperceptible.

To prevent an immediate shock, the proposal will double the base reward factor to 128 when it first goes live. This doubling operation just fills the 58.6% destruction amount mentioned earlier.

In other words, on the first day of the upgrade, the net issuance across the network can still maintain around 83% of the current level. Then, over the next 18 months, the parameters will gradually return to the normal 64, and the issuance will slowly slide down to the current 41%.

Summary: The decline in yield is a gradual dilution over a year and a half, not a sudden drop overnight. Those worried about "instantaneously bursting the DeFi bubble" actually overlook this buffer mechanism.

Baseline: Where Exactly is Ethereum Now?

Supply Dynamics

Where Does Issuance Come From?

All comes from staking rewards. After the merge, the new ETH has only one source: the consensus layer pays validators and distributes it according to fixed weights (denominator 64) across three categories of responsibilities: proof 54/64 (84.4%, 911,672 ETH/year), block production 8/64 (12.5%, 135,063), sync committee 2/64 (3.1%, 33,766).

Issuance is modeled as I(S) = 940.9 · √(S/32) ETH/year, which is the protocol's own reward curve. At S = 42.2 million, the corresponding consensus layer APR is 2.560%. The measured priority fee over the 23 days before August was 2,623 ETH, annualized to 41,500 ETH: equivalent to 0.098% of the staking base. The sum of the two is 2.658%, almost perfectly matching the published 2.66%.

Based on the measured priority fee, at least 96% of validator income comes from issuance, with a maximum of 4% from fees. Payments from proposers exceeding the direct priority fee in MEV-boost have not been captured, so the fee proportion is a lower limit. In any case, issuance dominates absolutely, and this ratio is the key to the entire debate.

Modeling the Proposal

Summary:

The earliest attempts were designed around "hiding" to create an entire network, rather than patching an existing one. Two coins lead the way, but their bets are completely opposite. The third case is designed for banks, not individuals, but belongs to the same family.

Application Based on Current Staking Levels, Without Considering Behavioral Responses

Reduction in issuance: −58.6%. Staking APR reduction: −56.4%. Removed dilution: 630,000 ETH/year = $1.55B/year = 0.53% of ETH market cap per year.

▲ The relationship between annual ETH issuance as a percentage of supply and staking rate. Today's curve is steadily rising; the EIP-8363 curve peaks at about 1.0% near a 20% staking rate; the permanent curve peaks at about 0.5%. Both curves drop to zero at a 50% staking rate.

Complete Curve (After Full Transition)

Issuance peaks at around 25 million staked ETH, approximately 0.505% of supply, before declining ------ consistent with EIP's own statements.

Equilibrium ------ The Number That Truly Ends the Debate

Stakers are not passive. If the yield is below their required return, they will exit, which will both raise the gross APR and lower b. Solving for the fixed point:

▲ The relationship between total staking yield and the amount of staked ETH under current rules and EIP-8363. The EIP-8363 curve intersects the 2% threshold at 31.2 million staked ETH and the 1.25% threshold at 40.9 million.

Read this table against the two loudest claims in the debate:

• "Issuance will go to zero." This only holds if marginal stakers are willing to work for about 0.5% returns. Under any reasonable required return, ETH still has an inflation rate of 0.3--0.5% per year. Supporters have exaggerated.
• "Staking will collapse." At the 2% threshold, the staking rate will stabilize at 26%: lower than today's 35%, but roughly the level for all of 2024. Critics have also exaggerated.

This mechanism is designed to be self-limiting. This is the most interesting property of the design and the least discussed point.

Can staking yield explain ETH's price?

First, Address the "Underlying Issue"

Is there a relationship between staking rate and yield? Yes: they are completely related, and it is determined by definition, not observed. This must be clarified first, as it determines what the data can and cannot explain.

The reward pool paid by the protocol scales by the square root of the staking balance, so the yield per ETH has a closed-form solution:

issuance(S) = 940.9 · √(S/32) ETH/year APR(S) = issuance(S)/S = 166.28 / √S

The more staked, the more the same pool is shared among more coins. The correlation between staking rate and issuance yield is structurally −1. Plotting the two together is essentially plotting an identity.

The only free variable is the difference between the published yield and the formula value: fee income. It was about 1.34 percentage points in 2022 and is now 0.10 percentage points.

The Correlation Itself

The answer: there is no correlation. 43 months, from January 2023 to July 2026. (The August 24 data refresh did not rerun this item; the window ends in July 2026, and subsequent price fluctuations do not affect this result.)

Regression Results

▲ The relationship between end-of-month ETH price and staking APR, along with OLS fit. The fit looks strong, but there is significant autocorrelation in the residuals.

This level regression is "significant" at p = 0.006 ------ but it is worthless. Durbin-Watson is 0.40, indicating serious serial correlation in the residuals, a textbook characteristic of pseudo-regression between two trend series. Both variables have trends, so they are correlated; the standard error is underestimated, and the p-value is not usable. Retaining this chart serves as a warning, not as evidence.

▲ The scatter plot of ETH monthly returns versus changes in staking APR for the same month, with the OLS fit line close to horizontal and a wide residual band.

After differencing to eliminate trends, the relationship disappears: p = 0.73, R² = 0.003. Durbin-Watson is 1.75, indicating that this setup is clean. The 95% confidence interval comfortably crosses zero in both directions ------ the data cannot even determine the sign of the effect, let alone its magnitude.

▲ The rolling correlation of changes in staking yield with ETH returns over 12 months, oscillating around zero and mostly falling within a range indistinguishable from zero.

Moreover, this is not a stable relationship hidden in noisy averages ------ the rolling correlation repeatedly crosses the zero axis, spending most of the time in a range indistinguishable from zero.

Between January 2023 and July 2026, ETH's staking yield fell from 3.98% to 2.50%, while ETH/BTC dropped 57%. Within the same window, the monthly correlation between changes in staking yield and ETH returns was −0.05. The yield was always there.

It did not support the price, nor did its compression cause a decline. If the existing reward curve's natural 37% yield reduction had no detectable price effect, then the burden of proof falls on anyone claiming "another cut will have an effect."

Note: The staking series is reconstructed from on-chain flow, about 5% higher than published data. The direction and shape are reliable, but the absolute level is not precise.

Supply Growth Rate Also Cannot Explain

If yield does not affect price, what about the supply numbers that this proposal truly changes? The same test, the same window, replacing yield with net supply growth rate.

▲ The relationship between ETH monthly returns and annual net supply growth rate. The fit line slopes downward, but the scatter points are very dispersed, and the relationship is not significant.

Slope −6.9 (for every percentage point increase in annual supply growth rate, monthly returns decrease by 6.9 percentage points), p = 0.18, R² = 0.044, Durbin-Watson 1.82. The 95% interval for the slope is −17.1 to +3.4.

Please read this result honestly, as it cuts both ways. This relationship is not statistically significant, and the interval crosses zero, so it cannot serve as evidence that "reducing supply growth will raise prices." But it is about fifteen times stronger than the yield relationship (R² 4.4% vs. 0.3%), and the sign is consistent with theoretical predictions. If either of the two variables truly has a marginal effect, the data suggests it is supply, not yield ------ and that is precisely the exchange made by EIP-8363.

How Deep is On-Chain Economics' Dependence on ETH Yield?

Liquid Staking

Lido alone accounts for 48% of Ethereum's total $48.5B DeFi TVL. Any claim that "DeFi will be fine" must first withstand this number.

What Does the Revenue Cut Mean for Them?

Liquid staking: Income affected. Lido handles about $602M in staking rewards annually, taking a 10% fee (about $60M/year). This time, a 58.6% cut in issuance means 633k fewer ETH rewards per year; based on Lido's 22.8% share, it earns about $35M less in fees annually: nearly half of its income from this segment. This is not insignificant for Lido, but on the broader Ethereum level, it is inconsequential. Moreover, regardless of how the yield changes, wstETH still outperforms WETH for any borrower wanting ETH exposure, maintaining its role as collateral.

LST as Lending Collateral - The Real Dependency

▲ The proportion of liquid staking tokens in TVL: SparkLend 66.9%, Aave V3 38.7%, Morpho Blue 10.4%, totaling 34.2%.

In the three major lending markets on Ethereum, out of $31.1 billion in collateral, $10.63 billion (34.2%) is from staking yield derivatives. SparkLend is a typical single point of failure: two-thirds of it is wstETH.

ETF Channels, Quantifying It

The most commonly cited objection is that reducing yields will deter institutional buying, as staking ETH ETFs market yields to those who cannot directly access returns. This channel does exist, but it is currently very small.

Products that clearly emphasize yield only account for 5.4% of ETF assets, 0.53% of all staked ETH, and 0.19% of total ETH supply. BlackRock's non-staking ETH product is ten times its size. Regardless of what is drawing institutional funds into ETH, staking yields are not the main selling point—allocative funds overwhelmingly buy non-staked exposure.

Two points prevent this conclusion from being a foregone one. First, the category of staking ETFs is still very young and growing: Bitwise and Grayscale are now working on staking ETFs for Solana, and Grayscale has also created one for Hyperliquid, so future risks may be greater than the current AUM. Second, declining yields may slow the conversion speed of non-staked ETF assets to staking share categories, but this is an impact on growth rates, not capital outflows. Both points do not change the magnitude: ultimately, this is a $0.5B group fighting over a $1.55B/year benefit transfer.

Conclusion and Judgment: When "Security Anxiety" Meets "Benefit Redistribution"

Let’s first clear away the grand narrative of security.

We must acknowledge that the core authors of EIP-8363 (such as Justin Drake and Jerome) have very serious intentions regarding network security. From a game theory perspective, once the overall staking rate crosses the 50% life-and-death threshold, Ethereum will lose its ability to resist extreme attacks through "Social Layer Defense" and face systemic parasitic risks from LST oligopolies that are too big to fail. Therefore, this proposal attempts to forcibly lock the staking rate in the safe zone through economic means of mandatory interest rate cuts.

However, on the flip side of security philosophy, the reality of on-chain data is much harsher.

Since 2022, Ethereum's "burn mechanism" has become virtually non-existent: the amount burned has plummeted by 98%, now only offsetting a mere 2.4% of the issuance. Regardless of your stance on the security intentions of EIP-8363, an unavoidable fact is that the previous mechanism of "allowing ETH supply to dynamically adjust to market demand" has ceased to function. Under the current L2 economics dominated by Blob, hoping for a surge in L1 fees to revive the burn mechanism is akin to wishful thinking. Ethereum's monetary policy has entered a "self-driving state without a steering wheel," and adjusting the issuance is the only trigger we can still pull.

Setting aside emotions, the real policy impact lies between the two extreme viewpoints.

Supporters shout "end ETH inflation," while opponents warn of a "collapse of the staking system"; both rhetorical positions deviate from mathematical facts. At the current staking scale of 42.2 million ETH, this proposal would only reduce the issuance by about 58.6% and the staking APR by about 56%. To bring issuance to zero? Staking would need to soar to 60.25 million ETH (43% higher than now). More importantly, this mechanism has built-in brakes: as yields decline, some stakers will exit, and the system will ultimately stabilize at around "26% staking rate, 0.48% annual inflation rate." What it actually delivers is merely a halving of dilution, not the destruction or subversion of anything.

Is the saved "half a percentage point" important? Numbers are more honest than words.

At current prices, reducing the issuance by 633,000 ETH annually equates to preserving $1.55 billion, about 0.53% of the total market cap. Don’t underestimate this proportion; it is roughly five times the entire L1 fee economy of Ethereum (about 0.10%/year). For an asset whose fee income has already dried up, plugging a structural bleed of 0.5% annually is by no means a "rounding error"; it is currently the largest economic lever available.

So what’s the cost? Will DeFi really collapse? Risks do exist.

Opponents often cite collateral, such as the fact that two-thirds of SparkLend is wstETH. But we need to clarify the difference between "exposure" and "dependency": as long as wstETH still has positive yields, it will always outperform regular WETH as collateral; this foundation is solid. What EIP-8363 will truly shatter is the "leveraged staking loop". When the underlying staking yield drops below 1.16%, unable to cover the interest on borrowed ETH, the funds relying on leveraged arbitrage will disintegrate. In other words, what will shrink is the leveraged bubble, not the collateral system itself. As for the direct losses on the protocol side, Lido will lose about $35 million annually: this is roughly half of their commission income.

Regarding the concern that "reducing yields will crash the market," the market has actually reached a conclusion long ago.

In the past 43 months of data, there has been no significant correlation between the rise and fall of staking yields and ETH price performance (p = 0.73, R² = 0.003). The staking yield dropped from 3.98% to 2.50%, yet it did not prevent the ETH/BTC exchange rate from plummeting 57% in July 2026. Yields are neither a moat for prices, nor has their compression become a trigger for market crashes. If the previous 37% yield decline did not make a splash in prices, then those claiming "another cut will cause Ethereum to crash" need to provide stronger evidence.

Why Is This Debate So Intense?

Because this is a zero-sum game where "losses are highly concentrated, and gains are extremely dispersed."

Peeling away the obscure technical language and grand security rhetoric, the essence of EIP-8363 is a brutal redistribution of wealth: currently, stakers take 100% of the newly issued ETH, but they only hold 35% of the tokens in the network. This means they are shifting the cost of inflation onto the other 65% of token holders. Cutting this $1.55 billion in issuance is equivalent to forcibly returning $1 billion in hidden wealth from stakers (intermediaries) to all non-staking ETH holders each year.

This is the real reason why all parties are so passionate:

• The harmed parties are extremely concentrated: Lido, LST issuers, re-staking protocols, leveraged players. This is a small, well-funded, and highly organized interest group. They are acutely aware of how much real money this proposal will extract from their pockets (Lido directly loses half its profits, leveraged loops face direct death).
• The beneficiaries are extremely dispersed: ordinary token holders who account for 65% of the supply. They can each year bear 0.5% less dilution, but this money is spread across nearly $300 billion in market capitalization, making it virtually silent; no one will take to the streets to rally for this.

This explains why the current debate is always filled with "hollow slogans." When an interest group cannot openly state, "this will take away a billion dollars in profits from us each year," they will raise the shield of "this will destroy DeFi"; and when researchers want to forcibly turn off the tap of monetary issuance, the most politically correct weapon is to "defend network security." Please understand the volume of opposition and support as a reflection of the concentration of interest distribution, rather than the mathematical correctness of the proposal itself.

Our Final Judgment

Strategy: Mildly bullish on ETH, clearly bearish on staking intermediaries/infrastructure. The proposal is likely to be rejected.

• At the asset level, our bullish stance is not based on the "myth of scarcity," but rather on common sense: removing a structural selling pressure of up to $1.5 billion a year (given to those who do not truly contribute to the earnings) is a highly cost-effective transaction when the only lever that can adjust supply fails. It may not be a dramatic reversal, but the compounding effect should not be underestimated.
• At the intermediary system level, the logic is flawless. The core valuation logic of Lido, LST, and LRT is entirely built on the "staking yield" that is about to be cut in half. This is not emotional panic; it is a tangible shrinkage of the profit and loss statement by 58.6%.
• As for the fate of the proposal? The probability is extremely low. In decentralized governance, the standard script that kills a good proposal is "concentrated harm vs. dispersed benefit." It is economically correct but politically difficult, which is our baseline expectation.

Conditions that trigger us to change our viewpoint (falsification indicators):

• On-chain data proves "new issuance is reinvested, not sold": If the flow of funds shows that newly minted ETH remains globally in automatically compounding LSTs and does not flow into exchanges to crash the market, then our selling pressure hypothesis is invalid.
• Staking ETFs bring massive buying pressure: Currently, the $500 million scale is insignificant. But if it expands tenfold, the marginal demand will outweigh the significance of inflation reduction.
• L1 transaction fees miraculously recover: If the burning mechanism re-dominates the fundamentals, the urgency of artificially intervening in the issuance will vanish.
• The negative correlation between supply and price is thoroughly evidenced: Currently, the relationship between the two is very weak. If data from the next year can confirm that "reducing supply must raise prices," this will become the most irrefutable quantitative pillar for being bullish on ETH.
