 Okay, good morning everybody. So, welcome to the 5th ECB Marker Prudential Research Conference. I would like to thank first the organizers of, uh, so my organizers of this event and, uh, I mean, they are all in the room, Marcos, Stefan and Angela. So, uh, just to give a bit of a kind of background of the questions that we want to kind of explore in this, in this conference, you know, Marker Prudential can be seen as a young policy. So some, some people say is a young policy that still needs to be brought to maturity. So, some people call it the younger sister or moderate policy. Uh, Matthew, you can also think of it as, you know, as in the fairy tale of, um, as, as Christian understand the ugly duckling. So, so the monetary policy is well developed. There is a lot of science behind it. Marker Prudential is still, is still developing. So it's still a kind of a ugly duckling of policy. So the fact that he's young is actually only partly true. Marker Prudential, uh, policy, you know, maybe it was not called that way, but as, as kind of historical roots, you know, when I had my first job and I did an introduction course in the Italian central bank. Uh, the, so one of the things I was told is that one of the objectives of monetary policy actually was to control total domestic credit. So this was the, you know, I was told that this was the key objective of monetary policy. Of course, at the time it was called monetary policy, but today we would probably call it Marker Prudential policy. And as you know, so many emerging markets have done, you know, Marker Prudential policy for, for many, many years. So it was a bit rediscovered after the government financial crisis, but it's not really a young policy. And also we know that these young sister of monetary policy has been helping monetary policy, you know, also in recent years, we know that there's been, you know, very pronounced monetary tightening in the last couple of years. And there was concern about, you know, financial stability risks. And so we know that among other things Marker Prudential policy has helped, you know, making this tightening cycle more, more kind of free of financial stability risk. And I think the vice president this evening will elaborate on this team. So just to kind of go on on this little comparison between Marker Prudential and monetary policy, so we know that monetary policy is as one target, you know, price stability, one instrument, and also one independent authority, the central bank running the policy. So what about Marker Prudential? It has certainly multiple instruments. I would say it has also multiple and perhaps unclear targets. So there can be also sectoral targets, for example. So so very, very multiple and kill targets and also several authorities. So in Europe, you know, the Marker Prudential policies is particularly, you know, vulcanized, I would say with, you know, with the divisional responsibility with the DCB and the national authorities. But it's the case also in other countries. So there are also other issues in the Marker Prudential policy that we still have to fully solve. And the conference today and tomorrow we will go through to some of them. So so we know that Marker Prudential policy tools can may leak. So the primary leakage. So in tomorrow we have we have a paper on that. We know that we may have, you know, a tightening bias. So so we know that some of the Marker Prudential tools are not easy to release. So they are easier to tighten than to release. And we saw this with the COVID crisis. So there was some release of Marker Prudential, but most of the capital release for banks, for example, came from Michael Prudential, Marker Prudential tools. And I would say also there is a strong competition. I mean, it should be, of course, it is the fact of cooperation, but it's also kind of intellectually competition from from Becky supervision. So so a lot of the things that we can do in Marker Prudential can also be done, you know, in the Marker Prudential setting. So so the question is also how to make it to cooperate and monetary policy does not have really this kind of kind of competitor. In the in the direction of making Marker Prudential simpler and perhaps sort of more scientific discipline in a bit like monetary policies. I mean, of course, on the one hand, you know, monetary policy is not as scientific as we sometimes think. So there are a lot of uncertainties also there, which perhaps are overlooked. But it's a question that I hope that David will shed some light on. For example, with this objective, you know, I believe that David is going to argue that growth at risk, you know, is a is a possible objective. So perhaps I would argue that maybe other value boost at risk, like bank equity at risk could be equally good objectives. But that is a discussion that that I will today and tomorrow to have. Also, another important discussion is how do we measure the stance. So how do we measure the stance of more potential policy? I mean, I know the IMF as some indicators, but these are very imperfect indicators. Just as we give an example, the long to value ratio, which is a key Marker Prudential tool, you know, maybe either very binding or not binding almost at all, you know, depends on the distribution or long to value ratios in the economy. So so the same tool, the same level of tool, say that a long to value ratio is point seven, you know, may imply, you know, a very tight or very loose policy. So so we have to, you know, measure that in a more, you know, in a finer way. So while and also while still searching for a soul for macro pru, you know, new frontiers, new topics are already emerging. So, so we know the liquidity, you know, is going to be an important topic. And we have a paper by Alexi Savov and co-authors tomorrow on this. So not back institutions also, you know, important for discussion or macro pru, what are macro tools can be used there in climate and, you know, clearly climate is also an area where macro prudential needs to get into. And we have also on this paper tomorrow. So let me stop here. You know how the ugly duckling fairy tale ends. So the ugly duckling becomes a beautiful swan. So let's hope the same will happen with macro prudential policy. Enjoy the conference and we look forward to all your contributions today and tomorrow. Thank you.
