IMF raises alarm on finance sector risks after Claude Mythos, wants international cooperation

The International Monetary Fund (IMF) has warned of systemic risks to global finance due to advanced AI models like Anthropic's Claude Mythos. According to the IMF, we need international cooperation as AI inevitably breaches cyberdefenses.

In Short

• IMF sounds alarm on Claude Mythos, other advanced AI models
• IMF says Mythos may put global finance system at risk
• It wants countries to work together to safeguard defenses

On April 7, 2026, Anthropic announced Claude Mythos – its most advanced AI model yet, particularly when it came to cybersecurity. However, unlike previous Claude models, Anthropic had no plans to release it to the general public. Why? The AI startup claimed that Mythos was just too powerful to be in everyone’s hands – something that could wreak havoc on the internet. Now, a month later, in a blog post, the International Monetary Fund (IMF) has warned that AI models like Mythos could create systematic risks to the global financial system.

Do note that IMF’s blog post comes at a time when governments around the world, including the US and India have raised similar concerns over Claude Mythos and future AI models. US President Donald Trump is reportedly considering an AI oversight committee to review AI models.

Claude Mythos may make it easier to target finance networks

In the blog post, the IMF stated that advanced AI models can “dramatically reduce the time and cost” that is needed to identify and exploit vulnerabilities. This could make it easier for bad actors to spot such flaws and use them to target systems that are widely used across organisations.

Anthropic has previously stated that Claude Mythos is able to spot thousands of cybersecurity flaws that were missed by humans across almost every software or operating system.

That is, once the AI is able to spot a vulnerability in one system, it is likely that a bad actor may be able to exploit it across various institutions that use similar tools. This, the IMF says, could allow for “correlated failures” that could disrupt the world of finance – payments, accounts, and almost everything else – on a systematic level.

Attackers have the advantage

According to the IMF, AI models like Mythos are going to “amplify existing cyberattack techniques by operating at machine speed” – the models can allow bad actors to target systems at a much faster rate. It further says that attackers may have the advantage since exploiting such “vulnerabilities can occur faster than patching and remediation.”

But that may not be the only reason to worry. The IMF claimed that it may be inevitable for existing cybersecurity defenses to be breached by more advanced AI models. And this may put almost every sector at risk that uses similar systems, such as energy, telecom and public services.

IMF wants international cooperation to prevent Mythos scare

At this point, it may seem that the future may be grim for cybersecurity with global systems at risk. But the IMF does have a plan. It wants the world to work together in building stronger safeguards, potentially by using AI, and sharing solutions.

The IMF stated that while “emerging and developing economies” may be at more risk of being targeted due to lower resources, it could allow bad actors to weaken the global system. As a result, it wants all countries to work together and share information.

Do note that currently Claude Mythos is available to a select group of around 40 companies as part of Anthropic’s Project Glasswing. This includes the likes of Amazon, Google, and Apple. This limited release has allowed some companies to receive more patches. But many non-US banks and financial groups have been left without access to the new AI model, raising concerns about uneven levels of protection.

As per reports, countries like India, the EU, and Canada are looking to get access to Claude Mythos to bolster their cybersecurity defenses. However, it is believed that the US government may not be willing to give complete access just yet, and may give foreign governments limited access to the model.
