A collapse within the worth of Ethereum might destroy the blockchain’s capacity to settle transactions and freeze greater than $800 billion in belongings, a Financial institution of Italy analysis paper warns.
The paper, written by Claudia Biancotti from the central financial institution’s Info Know-how Directorate, outlined a contagion state of affairs through which ETH’s worth collapse degrades the blockchain’s safety infrastructure to the purpose of failure.
Such a failure would ensnare and jeopardize the tokenized shares, bonds, and stablecoins that giant monetary establishments are more and more putting on public ledgers, the report argues.
Basically, this paper questions the idea that regulated belongings issued on public blockchains are insulated from the volatility of the underlying cryptocurrency.
In keeping with the report, the trustworthiness of the cost layer in permissionless networks like Ethereum is carefully tied to the market worth of unbacked tokens.
The entice of validator economics
The central argument of this paper is predicated on the elemental variations between conventional monetary market infrastructure and permissionless blockchains.
In conventional finance, cost techniques are operated by regulated establishments with formal supervision, capital necessities, and a central financial institution backstop. These entities are paid in fiat forex to make sure that the transaction is legally and technically accomplished.
In distinction, the Ethereum community depends on a decentralized workforce of “verifiers.” These are unbiased operators that validate and full transactions.
Nevertheless, they aren’t legally required to offer companies to the monetary system. Subsequently, they’re motivated by revenue.
Validators incur actual prices by way of {hardware}, web connectivity, and cybersecurity. Nevertheless, their revenues are primarily denominated in ETH.
The paper notes that even when staking yields are steady in token phrases, a “vital and sustained” decline within the greenback worth of ETH might wipe out the real-world worth of the proceeds.
If the income generated from validating transactions is lower than the price of working the gear, a rational enterprise will exit of enterprise.
The paper describes a possible “downward worth spiral with persistent unfavorable expectations” through which stakeholders rush to promote their holdings to keep away from additional losses.
Promoting staked ETH requires “de-staking,” which successfully deactivates the validator. The report warns that in excessive restriction situations, “no validators means the community will fail.”
In such a scenario, the cost layer turns into successfully non-functional, permitting customers to submit transactions that won’t be processed. Subsequently, belongings residing on-chain develop into “immovable” no matter off-chain creditworthiness.
When your safety price range reaches its restrict
Nevertheless, this risk extends past a easy processing outage. The paper argues that worth collapse considerably reduces the price for a malicious attacker to take over a community.
This vulnerability is framed by the idea of an “financial safety price range,” outlined because the minimal funding required to realize sufficient stake on a community to mount a sustained assault.
Ethereum permits attackers to control the consensus mechanism by controlling over 50% of the energetic verification energy. This case permits for double spending and censorship of sure transactions.
The paper estimates that as of September 2025, Ethereum’s financial safety price range is roughly 17 million ETH, or roughly $71 billion. Beneath regular market circumstances, this excessive price makes an assault “most unlikely”, the authors say.
Nevertheless, safety budgets will not be static. It fluctuates relying in the marketplace worth of the token. When the worth of ETH collapses, the greenback price of disrupting the community additionally falls.
On the similar time, as sincere validators exit the market to chop their losses, the full pool of energetic stakes shrinks, additional reducing the edge for attackers to realize majority management.
This paper outlines the perverse and inverse relationship. As the worth of a community’s native token approaches zero, the price of attacking the infrastructure drops sharply, however the presence of different worthwhile belongings might enhance the motivation to assault the infrastructure.
The “protected” asset entice
This dynamic poses specific dangers to the proliferation of “actual world” belongings (RWA) and stablecoins on the Ethereum community.
As of late 2025, Ethereum hosts greater than 1.7 million belongings with a complete capitalization of greater than $800 billion. This determine consists of the mixed market capitalization of the 2 largest dollar-backed stablecoins, roughly $140 billion.
In a state of affairs the place ETH loses virtually all of its worth, the token itself can be of little curiosity to a classy attacker.
Nevertheless, the infrastructure will nonetheless maintain billions of {dollars} of tokenized Treasury payments, company bonds, and fiat-backed stablecoins.
The report claims that these belongings would be the main targets. If an attacker features management of a weakened chain, they may theoretically double-spend these tokens by sending them to an alternate to promote for fiat forex, whereas additionally sending them to a different pockets on the chain.
This has a direct impression on the normal monetary system.
If issuers, broker-dealers, or funds have a authorized obligation to redeem these tokenized belongings at face worth, however on-chain possession data are compromised or manipulated, monetary stress shifts from the crypto market to real-world stability sheets.
With this in thoughts, the newspaper warns that the harm just isn’t restricted to speculative crypto merchants, “particularly if the issuer has a authorized obligation to refund at face worth.”
There are not any emergency exits
In conventional monetary crises, panic usually causes a “flight to security”, with contributors transferring their funds from misery to steady areas. Nevertheless, such a transition is probably not attainable within the occasion of blockchain infrastructure collapse.
For buyers holding belongings tokenized on the failed Ethereum community, a flight to security might imply transferring these belongings to a different blockchain. Nevertheless, this poses a serious impediment to this “infrastructure swap.”
First, cross-chain bridges, the protocols used to maneuver belongings between blockchains, are notoriously weak to hacking and will not scale effectively sufficient to deal with mass outflows in occasions of panic.
These bridges might be uncovered to assaults, and additional uncertainty might result in belongings being “speculated” and “weak stablecoins” being unpegged.
Second, the decentralized nature of the ecosystem makes coordination troublesome. Not like centralized inventory exchanges that may halt buying and selling to quell panic, Ethereum is a world system with conflicting incentives.
Third, a good portion of your belongings could also be locked up in DeFi protocols.
In keeping with information from DeFiLlama, roughly $85 billion is locked in DeFi contracts on the time of writing, with many of those protocols performing as automated asset managers with governance processes that can’t instantly reply to failures within the settlement layer.
Moreover, the paper emphasizes that there isn’t any “lender of final resort” within the cryptocurrency ecosystem.
Ethereum has built-in mechanisms to gradual validator exits, limiting processing to roughly 3,600 exits per day, however this can be a technical throttle, not an financial backstop.
The creator additionally rejected the concept that deep-pocketed entities like exchanges might stabilize collapsing ETH costs by “bulk purchases,” saying it was “most unlikely to work” in a real disaster of confidence, the place the market might assault the rescue fund itself.
regulatory dilemma
The Financial institution of Italy’s paper finally positions this contagion danger as a urgent coverage subject: Ought to permissionless blockchains be handled as crucial monetary market infrastructure?
The authors be aware that whereas some corporations want permissioned blockchains operated by licensed events, the attraction of public chains stays robust as a consequence of their attain and interoperability.
The paper cites the BlackRock BUIDL Fund, a tokenized cash market fund accessible on Ethereum and Solana, as a main instance of early-stage conventional monetary exercise on public rail.
Nevertheless, the evaluation means that this infrastructure import comes with distinctive dangers in that “the well being of the cost layer is tied to the market worth of speculative tokens.”
The paper concludes that central banks “can’t be anticipated” to jack up the costs of privately issued native tokens simply to make sure the safety of cost infrastructure. As an alternative, it means that regulators might have to impose strict enterprise continuity necessities on issuers of the underlying belongings.
Probably the most particular proposal within the doc requires issuers to take care of an off-chain possession database and specify a pre-selected “contingency chain.” This could theoretically enable belongings to be ported to a brand new community within the occasion of a failure of the underlying Ethereum layer.
The newspaper warns that with out such safeguards, the monetary system dangers slipping right into a sleepwalking state of affairs through which legit monetary plumbing shuts down as a result of collapse of speculative crypto belongings.
