„An AI bubble could become an issue for monetary policy“
Mr. Vujčić, Bulgaria will join the eurozone on 1January 2026. What obstacles were there to the introduction of the euro in Croatia in 2023?
The difference between Croatia’s or Bulgaria’s accession to the eurozone and the one of states prior to the euro crisis is that we not only had to fulfill the Maastricht criteria. Now we have additional requirements which include getting into the so-called close cooperation with the ECB. This basically means to join the European Banking Supervision, SSM, before joining the eurozone. So, a lot of work has to be done for a central bank prior to joining the euro area also regarding technical aspects. It started five and a half years before joining, and was, all in all, a two-year full-time project for us. And in our case, we had on top an additional challenge when introducing the euro.
What was that challenge?
Croatia was a unique case. We had to fulfill the Maastricht criteria including the inflation criteria in spring 2022. This was the time when inflation in Europe picked up dramatically, and more so in Central and East European member states due to different reasons. Even though Croatia had low inflation for 25 years before this, we were in risk of not passing the inflation criteria. We could have maybe asked for an exception to this rule because of the special circumstances. But it was better not to get into this situation, and we did not.
When a country is introducing the euro, there are always people saying this leads to inflation. Did this happen in Croatia?
As we had low inflation for a long time and then introduced the euro in a time of high inflation, many in Croatia started to blame the new currency for the high prices. That was a real difficult challenge in public communication. Unfortunately, most of the people still think this way. Even though there have been several studies on this topic. Depending on the study, the price increase due to the euro introduction was between 0.2 and 0.4 percentage points. That is not a lot in a time when inflation was around 10%. It helped us in communication that we had lower inflation than all non-euro countries in central East Europe, so, it could not have been that inflation was that high because of the euro.
How has the introduction of the euro influenced Croatia's economic development?
Croatia for sure benefits. The euro eliminated the exchange risks. We were quite euroized before in terms of deposits. Banks were hedging their foreign exchange risks. The level of the exchange risk was quite high. Before the introduction of the euro, a depreciation of our currency by 10% would basically mean an increase in the debt in domestic currency terms by also 10%. As a consequence of that we have significantly lower interest rates in Croatia, and the euro also boosts tourism, which is an important economic sector in Croatia.
Is it a disadvantage that Croatia no longer is solely responsible for monetary policy? It now must find the right stance with many other countries for the whole eurozone.
This is a theoretical disadvantage. As I mentioned, a high share of deposits and debt was in euro. We therefore pegged the exchange rate. Once we have done that, we could not deviate from the monetary policy of the ECB. Otherwise, the exchange rate would not have been stable. So, theoretically you are right, but in praxis you cannot lose what you never had.
Is it a problem for the ECB that the inflation data of the individual members is currently diverging quite significantly? France and Italy are well below 2%, while Croatia, for example, is at 4%.
We are all aware that you always will have some divergence. I would say cyclically, we move in the same direction. Yes, the individual inflation rates are different. Over the last few years Croatia, for example, has been growing much faster than eurozone average, wage growth was much higher, but, long run Croatia has very well aligned economic cycle with the eurozone one. Therefore, I think the monetary policy is long run beneficial for all. Certainly better than the counterfactual.
In your view, is there a risk that the ECB's monetary policy is more suited to larger economies than smaller ones?
I wouldn't say so. It is a question of how cyclicaly adjusted your economy is to the economic cycle of the eurozone as a whole. And there is a lot of convergence, as the most important trade partner of European countries are other European countries.
I don't have a special scenario in mind for a rate cut or a rate hike. Everything is circumstantial.

In early November, you said about the monetary policy of the ECB: We feel that we have done our job. Does this mean the ECB is probably done with rate cuts?
We have done our job in the sense that inflation we have brought the inflation from double-digit level to around 2%, without creating a recession in the eurozone. People take that for granted now, but two years ago most of the people I talked to feared the scenario of monetary tightening leading into the recession. On the other hand, I can also say that the task of a central bank is of course always a continuous job, never done. But for the time being, we are in a good place that we hopefully will stay as long as possible.
What have you to see in the economic data or in the ECB staff projection in December or March to be in favor of another rate cut?
I don't have a special scenario in mind for a rate cut or a rate hike. Everything is circumstantial. We have many things we look at to determine the inflation outlook and interest rate action.
What is your assessment? Are the risks for inflation and growth balanced at the moment?
Both are in my view balanced. Growth has been stronger than expected. For next year, we forecast healthy growth. Inflation has also been a bit higher than expected but that has only been a notch. We are still good at forecasting inflation. And we have been particularly good at forecasting wage growth, which is important for the service inflation. Wage pressure should continue to be moderate, which should lead to an inflation in the eurozone around our target.
The ECB tolerates minor deviations from the 2% inflation target. When is the deviation so big that the ECB adjusts monetary policy?
We should not try to micromanage inflation. If we don't see persistent pressure for inflation to come up or down, we should not change interest rates. Doing too much would just create unnecessary volatility. As I said, for the time being we are in a good place.
The December projection of the ECB will for the first time include numbers for 2028. If the inflation according to the projection would be below 2% for three years in a row, would this be a persistent downward deviation from target?
If you don't see large enough persistent deviation or an increasing downward trend, then it is fine. Thinking two or three years ahead, you always have increasing uncertainty. We better stick to the more visible future and make sure that the data we get is consistent with our projections. If they are, we are fine.
The current projections for 2027 contain a higher inflation due to the introduction of the EU Emissions Trading System ETS2. This will probably be postponed by the EU. Does this have any implication for you for monetary policy?
There is still lack of clarity on the exact timing and design. If not too large, this is an example of something that has an one time effect on inflation. If it is not too large and therefore does not propagates into further price increases, I think we should not make too much out it.
I am certainly a central banker in and out, in all aspects of central banking, and I want to stay the central banker in one way or the other.

A lot of people are warning at the moment that there is maybe an AI bubble growing. What is your view on this?
That is definitely one of the risks we have to consider very seriously. If there are disappointments in the benefits and revenues of AI, the evaluations at the stock markets could quickly reverse. If you have such high evaluations as now and so much money spent on investments in one sector and such a high concentration of the risks, then we must be very careful. Nobody can say what exactly will happen, but we must make sure that if there will be sharp corrections in the markets, we have a financial system that is resilient enough to withstand the shock.
Could a burst of an AI bubble lead to an adjustment of the monetary policy stance.
It depends on what exactly happens. If it leads to a large shock in the real economy because people lose money and curb their consumption this could lead to much lower growth. In such a scenario a bursting AI bubble would not only be a threat for financial stability but also an issue for monetary policy.
Of course, we cannot end this interview without asking you about the rumors you are interested in getting the next vice president of the ECB. What is your comment on this?
Well, let us see. The process will soon start officially, and then it is up to the governments to nominate their candidates. I have been a deputy governor or governor for 25 years now. I am certainly a central banker in and out, in all aspects of central banking, and I want to stay the central banker in one way or the other.
And more in general, how important is it in your point of view that Eastern Europe has a seat in the ECB board after the upcoming changes until end of 2027?
It is a fact that central East Europe never had a seat in the ECB Board. And it is also true that after Bulgaria’s accession to the eurozone, a third of the euro area members are from central East Europe.
