A new central bank paper challenges the assumption that tokenized real-world assets are immune to crypto volatility, outlining a scenario where a crash in ETH’s price breaks the network’s security budget.
The security of over $800 billion in tokenized assets rests on a fragile correlation between Ethereum’s spot price and validator incentives, according to a new working paper from the Bank of Italy. The research, titled “What if Ether Goes to Zero?,” warns that a catastrophic drop in the price of Ether could trigger a “death spiral,” forcing validators offline and effectively freezing the settlement layer for stablecoins and tokenized securities.
ETH traded flat at $3,111 (-0.4%) Monday as the market digested the report, which argues that the “settlement layer” thesis for institutional finance ignores a critical dependency: the network’s hired guns are paid in a volatile token.
The Mechanics of a Freeze
Authored by economist Claudia Biancotti, the Bank of Italy paper models a contagion event where a collapse in ETH price erodes the real-world value of staking rewards. While yields might remain high in ETH terms, the fiat value of those rewards could fall below the operational costs (hardware, electricity, bandwidth) required to run a validator node.
“Should such tokens incur a substantial and persistent loss in market value, validators might cease operations. Transaction settlement could slow or stop, and the infrastructure’s exposure to cyberattacks could increase.”
In this scenario, rational validators would exit the network to cut losses. A mass exodus would degrade the blockchain’s crypto-economic security, lowering the cost to attack the network just as the value of the assets secured by it, tokenized stocks, bonds, and stablecoins, remains constant.
The $800 Billion Trap
The research targets a specific blind spot in the “Real World Asset” (RWA) narrative: the assumption that regulated assets issued on public blockchains are insulated from the volatility of the native cryptocurrency. The paper estimates that by late 2025, the ecosystem of assets relying on Ethereum for finality had swelled to over $800 billion.
If the base layer’s security budget collapses, these assets become trapped. An attacker could cheaply acquire enough stake to censor transactions or reorganize blocks, rendering the transfer of regulated liabilities impossible regardless of their legal standing.
Institutional Context
The warning arrives as European regulators weigh the risks of allowing supervised intermediaries to use permissionless chains. The Bank of Italy’s findings suggest that without a mechanism to decouple security incentives from the volatile price of ETH, public blockchains may remain too risky for systemic financial infrastructure.
