Q-Day scenario 2026: Saxo Bank warns of crypto collapse due to quantum computers

Saxo Bank is outlining a thought game for 2026 in which a quantum computer breaks the most common digital security standards – and what that would mean for the financial world.

Overnight, the promise that our emails, bank transfers, crypto wallets and corporate systems are securely encrypted would be lost. According to strategist Neil Wilson, the mere hint of such a technological breakthrough would be enough to massively shake trust in digital infrastructure worldwide.

Attackers could use these new capabilities immediately, while defenders and affected parties would need months to replace the digital infrastructure they have used for decades.

Collapsing financial markets and gold as a safe haven currency

In such a scenario, financial markets would be the first to respond to the threat, with the crypto sector being hit the hardest. Old Bitcoin addresses in particular suddenly appear vulnerable, causing exchanges to freeze payouts.

Investors try to save their assets – and this creates a real mass panic. Saxo Bank sees the original cryptocurrency Bitcoin collapsing “towards zero” in this situation as trust in digital encryption evaporates.

At the same time, fear is also spreading to traditional finance. People start hoarding cash and assets and “buying everything they can get their hands on.” As a result, commodities are particularly in demand: As the ultimate “no-password” asset, in the scenario, the price of gold shoots up to $10,000 while the crypto market collapses.

Global emergency plan and the new winners

According to Saxo Bank, the consequences of the shock are mobilizing a massive response from authorities and companies. Central banks are opening emergency funding lines and regulators are ordering a global “maintenance weekend” to replace the digital locks on payment systems. A G20 pact sets deadlines to update everything from browsers to banking hardware. The money eventually flows back, but more slowly and at higher costs, while insurance premiums skyrocket.

Amid the chaos, clear winners and losers are emerging, according to MarketWatch. Those benefiting include providers of physical vaults for secure backups as well as new cybersecurity firms that deliver a quantum-safe solution. Even old-fashioned banks with strong cash distribution networks are experiencing a renaissance. On the losing side, however, are public cryptocurrencies, hot wallet exchanges and companies based on weak security standards.

Why Saxo Bank predicts the impossible

Saxo Bank expressly emphasizes that the annual “Outrageous Predictions” are not official forecasts for the coming year. According to the bank, the goal is to broaden the perspective and ask what is surprisingly booming when the world is shaking. The debate about these scenarios should prepare investors for surprises.

MarketWatch points out that the Danish investment bank has maintained this tradition for more than 20 years. Although predictions such as the demise of OPEC last year did not come true, chief market strategist John Hardy points to partial successes in the past. The bank predicted turbulence that later came true in a similar way, for example in connection with the volatility of the US dollar or the rise of NVIDIA.
