Inside the Bank of Italy’s Crisis Simulation: The Ethereum Doomsday Scenario

Central banks aren't just watching—they're war-gaming your portfolio's collapse.

The quiet hum of a Rome conference room just simulated a trillion-dollar black swan. No, it wasn't another sovereign debt crisis. This time, the stress test targeted Ethereum.

The Protocol Under Pressure

Forget minor bugs. The simulation modeled a perfect storm: a critical smart contract exploit cascading through DeFi, combined with a coordinated staking withdrawal crisis. The hypothetical trigger? Pick your poison—a state-level attack, a fundamental flaw in a core upgrade, or just the old-fashioned greed of a few large validators.

Liquidity Evaporates in Seconds

The model showed contagion doesn't need borders. A freeze in one decentralized lending protocol would ripple through interconnected apps, locking billions in seconds. The so-called 'decentralized' liquidity pools? They'd drain faster than a trader's confidence after a 10% dip.

Why a Central Bank Cares

It's not about protecting crypto bros. It's about systemic risk. When traditional finance has quietly built bridges to this $400B+ ecosystem—through ETFs, corporate treasuries, and institutional custody—a crash there doesn't stay there. The simulation maps how a crypto crisis could jump the fence into the real economy. A classic case of bankers running drills for a fire in a house they publicly claim is made of sticks.

The takeaway? The suits in Rome now have a detailed playbook for an Ethereum meltdown. They're preparing for a world where 'code is law' meets the very human law of panic. The real question isn't if they'll intervene, but when—and whose assets get saved first. After all, what's a little bailout among fintech friends?

Bank Of Italy Issues Technical Analysis

According to the Bank, permissionless blockchains like Ethereum act as settlement systems for a wide range of tokens and contracts. The institution treats the question as a stress test on infrastructure rather than only on asset prices.

The note warns that if a native token loses most of its market value and the drop remains persistent, the economic incentives that keep validators running could vanish. Validators might exit, the paper says, and that could make settlement slow or stop.

What The Paper Found

Based on reports in the Bank’s paper, the chain of effects is simple and worrying. Validators are paid in ETH. If ETH has next to no value, that payment no longer motivates operators.

As a result, transaction settlement could slow dramatically or, in extreme cases, halt. The paper also highlights that other assets using the chain — for example, tokenized securities or fully backed stablecoins — could become hard to MOVE or could face security problems if the network’s defenses weaken.

Italy’s broader regulators have recently stepped up their look at crypto risks. Reports show the Economy Ministry ordered a review of safeguards, and the Bank of Italy’s paper fits into that wider push to quantify risks tied to new payment systems.

Reuters and other outlets covered the regulator-level review in December and January as authorities pressed firms to meet emerging rules.

The authors do not claim the scenario is likely. Instead, the exercise is framed as a way to show how market risk can turn into infrastructure risk. The paper points out there is no formal mechanism to “shut down” a permissionless chain in an orderly way.

Any mitigation WOULD rely on voluntary action by validators, major staking firms, or protocol changes proposed and adopted by the community. That uncertainty is the main policy concern.

The Bank of Italy’s note is a technical, measured look at a worst-case scenario. It uses concrete data to argue that a collapse in Ethereum market value would not only hit holders but could also impair the functioning of systems that now run on Ethereum.
