If Ethereum’s proposed 54% reward cut passes, DeFi’s favorite loop threatens to become a daily loss machine

A newly proposed Ethereum staking reward cut, outlined in Ethereum Improvement Proposal 8361 (EIP-8361), would lower validators’ yield from 2.6% to about 1.2%, a 54% reduction phased in over 18 months. The mechanism is a burn: validators lose a larger share of their consensus reward as the total amount of staked ETH climbs, and the burned ETH disappears from supply.

At the proposal’s saturation point of 60.25 million ETH staked, roughly half of supply, the burn would cancel the consensus issuance a correctly performing validator would otherwise earn.

Priority fees and MEV sit outside it: the authors put that income at up to 0.20% today, against a consensus issuance that covers at least 93% of current staking yield.

That reward funds a chain of products that includes liquid staking tokens like stETH, whose yields are priced off it, leveraged staking loops that borrow against it, and lending markets from Aave to Pendle that set their rates around it.

Cutting the base forces every layer above to reprice.

Aave founder Stani Kulechov has warned that unpredictable or near-zero consensus yield could weaken institutional ETH demand, solo staking, ETH borrowing, and ETH-denominated DeFi.

Mike Silagadze from ether.fi has gone further, arguing that the proposal threatens staking-linked DeFi broadly and confidence in Ethereum’s ability to set its own monetary policy. Both reactions point to the leveraged ETH loop.

Why Kulechov says the Ethereum staking reward cut could erase ETH borrowing

A user deposits wstETH or another liquid staking token as collateral on Aave, borrows WETH against it, converts that WETH into more staked ETH, and deposits it again.

Aave’s case study on Lido describes this structure, and its E-Mode setting makes the loop capital-efficient by treating stETH and WETH as correlated assets.

Galaxy Research noted that debt grows faster than collateral once WETH borrowing costs exceed staking yield, raising the odds of liquidation.

At today’s 2.6% consensus yield and a WETH borrow rate near 1.5%, the unlevered spread runs about 1.1 percentage points positive. Drop the yield to 1.2% under the EIP’s full curve, and the same spread turns negative by roughly 0.3 points before any leverage applies.

At five times leverage, a trade that used to add income starts to cost the user money every day it stays open.

Kulechov added that the proposal removes one of DeFi’s largest recurring sources of demand for ETH borrowing. If loopers unwind their positions and repay WETH debt, borrowing utilization on Aave, Morpho and Spark falls, and lender APYs compress with it.

Lower utilization should also pull down WETH borrowing costs, which could eventually restore a smaller positive spread. Those borrowing costs would need to fall well below today’s levels before a 1.2% staking yield makes leveraged staking worth the risk again.

How the Ethereum staking reward cut could reach beyond Aave

Silagadze’s post argued that liquid staking tokens like Lido’s stETH and Rocket Pool’s rETH would see their headline yield fall alongside consensus issuance. Meanwhile, restaking tokens such as ether.fi’s weETH would lean harder on incentive and points programs to hold their edge.

Pendle, which lets users trade fixed and floating ETH yield directly, would reprice its PT and YT markets around the lower floating rate.

Automated ETH vaults that run loop strategies would need to cut leverage or take on more risk to defend their advertised returns, and Curve pools that support LST redemptions could see thinner secondary liquidity if loopers exit in size.

Solo stakers face a narrower version of the same math: their operating costs stay fixed while the reward covering them shrinks.

Silagadze’s claim that seven of the top ten DeFi protocols would face a capital exodus is his own assessment, not an independently modeled outcome. But the products he names, such as Aave, Morpho, Pendle, Lido, and ether.fi, all price a return that traces back to the same consensus reward EIP-8361 would burn.

Kulechov pointed to a smaller staking return that could push yield-seeking ETH holders toward stablecoins. If that happens, DeFi activity moves from ETH-denominated lending into stablecoin lending and fixed-yield products, while ETH-native staking and LST demand lose relative share within the same protocols.

The Ethereum staking reward cut reduces issuance, which benefits passive ETH holders by reducing dilution, while a lower yield pushes out investors who value ETH as a productive, income-generating asset. The available data does not show whether scarcity or income would have the greater effect on ETH’s price.

Why builders call the rollout rushed

EIP-8361 sits on GitHub as an open Core EIP awaiting editor review, and the authors posted it to the Ethereum Magicians forum roughly 48 hours before the Hegotá Proposed for Inclusion deadline.

One forum participant called that window inadequate for reviewing a monetary-policy proposal of this scale.

Jérôme de Tychey rejected the rushed-process framing. He said that “Proposed for Inclusion” opens debate, and that the proposal still needs a separate step to enter an upgrade.

Ethereum’s issuance debate has run since 2023, and an 18-month phase-in, combined with normal upgrade scheduling, gives the market roughly two years to adjust.

He also noted that the validator entry queue has been running near its cap. If entry stays saturated while few validators exit, staked ETH could pass 70 million, above 55% of supply, by Jan. 1, 2028.

In Tychey’s framing, acting now lets the market settle below the 50% saturation point on its own terms. Waiting risks a larger, more disruptive adjustment later.

Two ways the leverage trade could settle

The bull case rests on timing working in the market’s favor. As loopers unwind, WETH utilization and borrowing costs fall quickly enough to rebuild a smaller positive spread of roughly 0.3 to 0.5 percentage points over the borrowing costs that larger loopers reportedly target.

Lower issuance attracts ETH buyers who value scarcity over yield, and DeFi lending markets settle around the new, lower floor without losing much ETH-denominated activity.

The bear case has the yield cut landing sooner than borrowing costs can catch up. Loops turn unprofitable before WETH utilization has time to fall and reprice lending rates, and LST and LRT demand drops as loopers exit for good.

Yield-seeking capital rotates into stablecoins and other chains. Ethereum ends up with a smaller, less ETH-native DeFi market than the one the proposal was written to protect.

Once the Ethereum staking reward cut activates, the burn schedule runs on a fixed timeline. WETH borrowing costs will adjust at whatever pace the market sets. That gap determines whether the leveraged-staking trade that fueled activity on Aave, Morpho, and Pendle survives the transition or disappears with it.
