What Andrew Bailey said

Written from the verified transcript and checked against it. Every figure links to the moment it was said.

Andrew Bailey, Governor of the Bank of England, said UK banks still lack access to Anthropic's Mythos AI model, despite a promised trial. He noted the delay is tied to the US administration's process, which he cannot explain. Bailey stressed the need for a controlled but fast assessment process and highlighted the importance of international cooperation on cyber risks, as banks are interconnected. He pushed back on the idea that US dominance is problematic, focusing instead on spillover risks. On private credit, he called it a good thing but warned of interconnections with banks and rising outflow requests, prompting a second system-wide exploratory scenario. He said stablecoin proposals will come before summer, possibly with issuance limits, and emphasized global rules for cross-border use. He expressed skepticism about a digital pound, favoring tokenized deposits and citing Project Agora for cross-border payments. He also described using AI for data, coding, and testing MPC minutes.

Key takeaways

  1. UK banks still lack access to Mythos, with delay tied to US administration process.
  2. Bailey calls for international approach to cyber risks due to bank interconnectedness.
  3. Bailey skeptical of digital pound, prefers tokenized deposits and Project Agora.

  1. 0:00So do you know what happened?
  2. 5:01Is that, I mean, are you getting a hearing on that from us in terms of the risks of that?
  3. 7:15Are you now scrapping the idea of capping the amount of stablecoin that individuals and businesses can?
  4. 9:23Will there ever be a Bank of England digital pound?
  5. 10:40Our economist team are using AI on what the Bank of England says, and we're judging whether or not it's in the direction of travel. How are you using it?
Interviewer 0:00 ↗
At this conference, we did have an opportunity to hear from you and talk to you about monetary policy this morning. But there's also been a lot of conversation about AI and the potential impact on the economy of AI, but also the cyber security risks associated with new AI tools. And of course, most recently, the one we've been hearing about worrying about is Mythos. Can I just confirm, have UK banks got access to Mythos now? Are they getting it on that trial basis so they don't have access to Mythos at the moment? And that's an issue that is very important. And by the way, this is a very important development. But there are other models out there. I mean, Mythos isn't the only model out there. There's obviously something of a race going along to move the technology on. And, you know, I'm very optimistic that they are either by other just have or about to get the major UK banks have access to other models which will get them substantially. But just going back to the Mythos also because we had a story and I think the Anthropic UK and Northern Europe's head, the company that owns it, makes Mythos. They told Bloomberg last month that it would be within a week that UK bank chiefs were going to be able to be part of that, the Glasswing project. So do you know what happened?
Andrew Bailey 1:10 ↗
Well, there was a yes. So there has been a Glasswing phase two, been talked about really for the last six weeks or so, but it hasn't happened yet. And I think this has been somewhat caught up in the process with the US administration.
Interviewer 1:26 ↗
So sort of just reading between the lines, it sounds like Anthropic had certainly told us on Bloomberg Television that it was going to be just a matter of days or a week or so. And it's the US administration that has potential.
Andrew Bailey 1:38 ↗
Well, we're not party to that process. I think to be fair to Anthropic, I think they, you know, they have been working very hard. They want, you know, access to critical parties. And it's very important that still, you know, I think actively seeking that. Quite why the process is a bit different from one company to another, I'm afraid I can't explain to you. Obviously, from our point of view, given, you know, our concern about the risks involved in this, it's very important that there is access. And, you know, what I really want to see is evolve a process quickly where we can have a sort of controlled but fast process to assess these models and frankly, is to, well, what my head of, I'd say at the Bank of England told me is a ton of patching that then has to follow very quickly to fix the things that these models are finding.
Interviewer 2:25 ↗
And I guess, and as part of this conversation, I guess we also think about the conversations I have when I get nervous is when they also talk about the open source. The companies that are a bit behind the way they get uses is to have open source, which means if you discover that the so-called bad guys are using that technology to rob banks or whatever it is, you're then not able to turn it off in the way you can with the others.
Andrew Bailey 2:48 ↗
Well, look, I'm not speaking as an expert on the subject. I could be an asshole. Well, yeah, we try to learn quickly. I think two things that I've taken from the many discussions we've had. One is that I think if you have kept your cyber defenses up and better prepared, you will go into this process in a better place than if you haven't. And we've worked very hard with the UK banks over many years. I will go on doing so. Secondly, I think you're right on the open source point. Now, I think what Anthropic is certainly saying is that open source is more of a vulnerability than closed. And that's certainly a conclusion they've drawn from all the work they've done now. I mean, the two things, I think, however, one is there's a lot of open source out there. Two, again, I'm not an expert in this field. There's a lot of almost theological doctrine about open source and not open source, which this is somewhat pushing against.
Interviewer 3:48 ↗
So, yeah, I think because you tended to say there's been a sort of inclination towards open source, but in this case it feels like it's being questioned. Yeah. Yeah. I mean, does it highlight sort of overall the risks of, I mean, going back to the Anthropic thing of having US-owned companies being absolutely dominant in this space and actually UK banks being in the position of kind of going begging to the Americans to get access to it.
Andrew Bailey 4:11 ↗
Well, I don't take your position on, you know, where the sort of in a sense, the companies are sort of developing these things because this is a very, very big development and it's actually very important. And there are many good things that will come out of this. What I would say is that the spillovers from this sort of some cyber risk are so big that we can't just have a, you know, single sort of national approach towards dealing with the consequences and mitigating it. There's got to be an international approach to this. It's got to be in a sensible, sort of firmly based international process, because I think anybody who thought, well, I've dealt with my banks, that's okay. I'm afraid that won't work because they're all so heavily interconnected. We've got big payment systems, big messaging systems, so that approach won't work.
Interviewer 5:01 ↗
Now, as chairman of the Financial Stability Board, you obviously involved lots of discussions around sort of global efforts on financial stability and looking for risks. And one area again, where people are looking nervously at the US in particular, is the run up of private credit and whether there should be a more of a sort of a tougher approach to at least having more reporting requirements or other things on private credit. You've highlighted that a lot of traditional banks and institutions are now very much intertwined with private credit. Is that, I mean, are you getting a hearing on that from us in terms of the risks of that?
Andrew Bailey 5:34 ↗
Excuse me? Yes, I think. Look, first of all, private credit is playing an important role. I think it's a good thing. Yeah. Let's come back to AI for a moment. You know, we've got a very big investment demand going on for it to support the innovation. And in the tech sector more broadly and private credit is an important part of meeting that demand. And that's a good thing. What I think, you know, I think we have to look carefully at is the word private can be misleading in some ways because it is not an island on its own. It is connected into the broader system. A lot of the underpinning liquidity will come from the banking system. It is connected into the banking system. And that's inevitable. So it's very important that we understand those interconnections, how they work. All that points of sort of fragility in there. That's why at the Bank of England, we're doing the second system wide exploratory scenario to follow on the one we did on hedge fund activity and major government bond markets a couple of years ago. So that's the first thing. The second thing I think is important is, and I think this is particularly true with the spread into sort of so-called retail investment, is do the investors understand the assets they've got and the characteristics of those assets? Because there are clearly, you know, there are some signs of strains in the markets. I think they're often described as idiosyncratic. Okay. Every incident will have a different story attached to it. But we are seeing some increase in requests. Quite a big increase in requests for outflows to take liquidity out. And I think how that plays out will depend on what investors think. They think well thought they had relative to what they sort of now think they've got.
