An Ethereum worth collapse might break the blockchain’s potential to settle transactions and freeze over $800 billion in belongings, a Financial institution of Italy analysis paper warns.
The paper, authored by Claudia Biancotti of the central financial institution’s Directorate Normal for Data Know-how, outlined a contagion state of affairs the place ETH’s worth collapse degrades the blockchain’s safety infrastructure to the purpose of failure.
Such a breakdown, the report argues, would lure and compromise tokenized shares, bonds, and stablecoins that main monetary establishments are more and more inserting on public ledgers.
Primarily, the paper challenges the idea that regulated belongings issued on public blockchains are insulated from the volatility of the underlying cryptocurrency.
In response to the report, the reliability of the settlement layer in permissionless networks like Ethereum is inextricably tied to the market worth of an unbacked token.
The validator economics lure
The paper’s core argument rests on the elemental distinction between conventional monetary market infrastructure and permissionless blockchains.
In conventional finance, settlement methods are operated by regulated entities with formal oversight, capital necessities, and central financial institution backstops. These entities are paid in fiat foreign money to make sure trades are finalized legally and technically.
In distinction, the Ethereum community depends on a decentralized workforce of “validators”. These are unbiased operators who confirm and finalize transactions.
Nonetheless, they don’t seem to be legally mandated to serve the monetary system. So, they’re motivated by revenue.
Validators incur real-world prices for {hardware}, web connectivity, and cybersecurity. But, their income is denominated primarily in ETH.
The paper notes that even when staking yields stay secure in token phrases, a “substantial and chronic” drop within the greenback worth of ETH might obliterate the real-world worth of these earnings.
If the income generated by validating transactions falls under the price of operating the tools, rational operators will shut down.
The paper describes a possible “downward worth spiral accompanied by persistent unfavorable expectations,” the place stakers rush to promote their holdings to keep away from additional losses.
Promoting staked ETH requires “unstaking,” which successfully deactivates a validator. The report warns that in an excessive restrict state of affairs, “no validators implies that the community doesn’t work anymore.”
Below these situations, the settlement layer would successfully stop to operate, leaving customers capable of submit transactions which can be by no means processed. So, belongings residing on the chain would develop into “immovable,” no matter their off-chain creditworthiness.
When safety budgets break
In the meantime, this risk extends past a easy halt in processing. The paper argues {that a} worth collapse would drastically decrease the price for malicious actors to hijack the community.
This vulnerability is framed by way of the idea of the “financial safety price range”— outlined because the minimal funding required to accumulate sufficient stake to mount a sustained assault on the community.
On Ethereum, controlling greater than 50% of the lively validation energy allows an attacker to control the consensus mechanism. This example would allow double-spending and the censorship of particular transactions.
As of September 2025, the paper estimates Ethereum’s financial safety price range was roughly 17 million ETH, or roughly $71 billion. Below regular market situations, the writer notes, this excessive price makes an assault “extraordinarily unlikely.”
Nonetheless, the safety price range will not be static; it fluctuates with the token’s market worth. If ETH’s worth collapses, the greenback price to deprave the community falls in tandem.
Concurrently, as trustworthy validators exit the market to chop losses, the whole pool of lively stake shrinks, additional decreasing the brink for an attacker to achieve majority management.
The paper outlines a perverse inverse relationship: As the worth of the community’s native token approaches zero, the price of attacking the infrastructure plummets, but the motivation to assault it might enhance as a result of presence of different worthwhile belongings.
The lure for ‘secure’ belongings
This dynamic poses a selected threat to the “real-world” belongings (RWAs) and stablecoins which have proliferated on the Ethereum community.
As of late 2025, Ethereum hosted greater than 1.7 million belongings with a complete capitalization exceeding $800 billion. This determine included roughly $140 billion in mixed market capitalization for the 2 largest dollar-backed stablecoins.
In a state of affairs the place ETH has misplaced almost all its worth, the token itself can be of little curiosity to a classy attacker.
Nonetheless, the infrastructure would nonetheless home billions of {dollars} in tokenized treasury payments, company bonds, and fiat-backed stablecoins.
The report argues these belongings would develop into the first targets. If an attacker positive factors management of the weakened chain, they might theoretically double-spend these tokens by sending them to an alternate to be bought for fiat whereas concurrently sending them to a unique pockets on-chain.
This brings the shock instantly into the normal monetary system.
If issuers, broker-dealers, or funds are legally certain to redeem these tokenized belongings at face worth, however the on-chain possession data are compromised or manipulated, the monetary stress transfers from the crypto market to real-world stability sheets.
Contemplating this, the paper warns that the harm wouldn’t be confined to speculative crypto merchants, “particularly if issuers have been legally certain to reimburse them at face worth.”
No emergency exit
In standard monetary crises, panic typically triggers a “flight to security,” wherein members shift capital from distressed to secure venues. Nonetheless, such a migration could also be unattainable throughout a collapse of blockchain infrastructure.
For an investor holding a tokenized asset on a failing Ethereum community, a flight to security might imply shifting that asset to a different blockchain. But, that presents vital obstacles to this “swap in infrastructure.”
First, cross-chain bridges, that are protocols used to maneuver belongings between blockchains, are notoriously weak to hacks and should not scale to deal with a mass exodus throughout a panic.
These bridges might come underneath assault, and additional rising uncertainty might trigger belongings to be “speculated towards,” doubtlessly inflicting “weaker stablecoins” to de-peg.
Second, the ecosystem’s decentralized nature makes coordination tough. In contrast to a centralized inventory alternate that may halt buying and selling to chill a panic, Ethereum is a world system with conflicting incentives.
Third, a good portion of belongings could also be trapped in DeFi protocols.
In response to DeFiLlama information, about $85 billion is locked in DeFi contracts on the time of writing, and lots of of those protocols act as automated asset managers with governance processes that can’t reply immediately to a settlement-layer failure.
Moreover, the paper highlights the shortage of a “lender of final resort” within the crypto ecosystem.
Whereas Ethereum has built-in mechanisms to sluggish the pace of validator exits — capping processing to about 3,600 exits per day — these are technical throttles, not financial backstops.
The writer additionally dismissed the concept that deep-pocketed actors like exchanges might stabilize a crashing ETH worth by way of “large buys,” calling it “not possible to work” in a real disaster of confidence the place the market would possibly assault the rescue fund itself.
A regulatory dilemma
The Financial institution of Italy paper finally frames this contagion threat as a urgent coverage query: Ought to permissionless blockchains be handled as important monetary market infrastructure?
The writer notes that whereas some companies favor permissioned blockchains run by approved entities, the attract of public chains stays robust attributable to their attain and interoperability.
The paper cites the BlackRock BUIDL fund, a tokenized cash market fund out there on Ethereum and Solana, as a primary instance of early-stage conventional finance exercise on public rails.
Nonetheless, the evaluation means that importing this infrastructure comes with the distinctive threat that the “well being of the settlement layer is tied to the market worth of a speculative token.”
The paper concludes that central banks “can’t be anticipated” to prop up the value of privately issued native tokens merely to maintain the settlement infrastructure safe. As a substitute, it means that regulators could have to impose strict enterprise continuity necessities on issuers of backed belongings.
Essentially the most concrete proposal within the doc requires issuers to take care of off-chain databases of possession and to designate a pre-selected “contingency chain.” This could theoretically enable porting belongings to a brand new community if the underlying Ethereum layer fails.
With out such safeguards, the paper warns, the monetary system dangers sleepwalking right into a state of affairs the place a crash in a speculative crypto asset halts the plumbing of authentic finance.
