Select Committee on European Union Minutes of Evidence


Examination of Witnesses (Questions 160-172)

Professor Richard Portes

17 JULY 2007

  Q160  Lord Kerr of Kinlochard: I agree with you that the Sarkozy line on competition at EU level will be rather important. I hope that it will be a different line from the Chirac line. I do not think we know. I think you can be reassured that the removal of the words "competition that is free and unfettered" from the draft constitutional Treaty will have no legal impact whatsoever. The words were never in the Treaty of Rome, or Maastricht, or Single European Act, or Amsterdam or Nice. I know, because I wrote them in 2002, and, alas, the French never liked them, at the time. Now my words have disappeared. Since they never were in a ratified Treaty, that has no effect on EU competition policy, run by that brilliant Frenchman Michel Petite, in Brussels. His powers will be in no way constrained by their removal. I agree with you, it is interesting because we do not know the President's motive. If on national champions, economic patriotism, he is going to run against Brussels, we are back to Chirac. If, on the other hand, he is going to maintain domestically that he has changed Brussels, and so reduce hostility to Brussels, there possibly one could see the sad death of my language as a good outcome, if it enables him to change. I was going to take you on from competition policy to Paris' attacks on another brilliant Frenchman, M Jean-Claude Trichet, and the way the ECB operates monetary policy. M Trichet is told on a daily basis, or was, in President Chirac's time, that his monetary policy is too tight, his interest rates are too high, and the euro is so ludicrously hard as to seriously penalise French trade. Do you think the ECB has operated monetary policy wisely? The stress on the inflation objective, is that right, or should they have, as French commentators have argued down the years, an additional growth objective? And do you think the objectives should be set by ECOFIN or by M Trichet?

  Professor Portes: You will recall, of course, My Lord, that the conflict between President Chirac and Mr Trichet, when he was Governor of the Banque de France, was exactly the same conflict over the franc before, and that did not change. It is natural, it is absolutely natural, that politicians, where the independence of the central bank has not been fully established, should take that line; we are familiar with that, we saw plenty of it. What we have not seen, quite interestingly, since 1 May 1997, is that kind of political grandstanding pressure, whatever you like, in this country, and I think that is quite interesting but not totally the point. Let us get to the point, which is the sorts of questions which you put about monetary policy itself, that is to say, some of Mr Sarkozy's criticisms, whether economically well informed or not, might there be some justice in them. I think, on the whole, not; no. Take the first question about the restrictiveness of monetary policy. If you compare long-term real interest rates in the United States and the European Monetary Union since the inception of monetary union you will find that there is very little difference, we are talking at most times about differences of 50 basis points; nothing in it really. That is what we think is relevant for growth, we do not think that the short-term policy rate is relevant for investment decisions. What we have observed is, as I say, regardless of the monetary policies being applied, very similar long-term interest rates, and therefore, from that point of view, a very similar environment for growth, and the Fed has not been criticised on that count. The second way of looking at it is something which was popular for a while among academic researchers and recently has been taken up by private sector economists. I will put in the technical term but then I will try to make it reasonably intelligible, the Taylor Rule, looking at what a Taylor Rule would suggest about the behaviour of the central banks. The bottom line of all this is to try to formulate, quite precisely and econometrically, what it is that, say, the Federal Reserve Board of the United States, or the old Bundesbank, would have done if they had been facing the same economic data as the European Central Bank faced. You can investigate the behaviour of the Fed and of the Bundesbank over time and then say, suppose you had that decision-making process and the way in which it was operating, what would they have done if they had been looking at the same employment, price stability, all this stuff. The answer, uniformly, whether it is academic researchers or private sector economists who are doing these estimates, is that the Fed and the Bundesbank both would have run more restrictive, tighter monetary policies than the European Central Bank actually has done. There was a little piece in The Economist about this, a year or so ago, maybe it was two years ago, coming out of a piece by David Mackie, of JP Morgan, which had done this in a reasonably intelligible way, and the evidence is fairly clear on that. I do not think the policy has been too restrictive. I think the problems of growth in the euro area have been problems of a different kind and, as I said, now we can see some progress on that. Should the ECB consider other factors than price stability; well, the short answer is, of course, the Treaty says no, the Treaty says only when those are without prejudice to price stability, considering those other factors. That said, look at the practice, and if you actually look at the behaviour of the ECB since 1999 I think it is fairly clear that they have looked at other factors besides price stability. They have looked at that, they have looked at the level of economic activity and this comes out just from looking at monetary policy decisions and what the data were that were there at the time. I think the simple answer is, whether you think it should or not, whether you think it ought to have a different mandate from the one that it actually has, in fact, it has not been looking only at price stability, I think, and that is probably clear. This is relevant to the inflation target issue, if you look at the actual performance on inflation, sometimes it has been 80%, more often than not, month by month, it has been above 2%, actually. If you do just a simple count of the annualised rate of inflation on a monthly basis, from month to month, in fact, the majority of months it has been at a rate above 2%. In that sense, again, you might say that, in practice, they are running a regime in which 2% is not the upper inflexible limit but, in fact, it is rather more symmetrical, around 2%; but that just comes out of the data again. Should ECOFIN or the Eurogroup have the power to set the inflation target, ECOFIN, no, ECOFIN has no standing, in my view, in this matter, it is a Eurogroup matter. Yes, I think that here the UK model is absolutely correct, the target should be set by the political authorities, and that is a matter of policy, that then the Bank is there to implement. The current position, which is effectively the result of the Maastricht Treaty, that the Bank decides whatever it wants to do on the target, I think that is wrong, I think it gives the Bank too much independence and does not give a proper political/policy dimension to monetary policy. There is a role for the political authorities. I think we have it right in the UK.

  Lord Kerr of Kinlochard: This was the inherent tension at Maastricht: the majority of those who are now in the Eurogroup would totally agree with you, but the Germans did not, so we ended up where we did.

  Q161  Chairman: For fear of running out of time, I am going to jump to the back end of the questions because it is what you really want to talk about. I have the question formulated as what has been the impact of the euro on the functioning of European capital markets, and then we go on to the levels of trade. Can I say, before we start talking about the European capital markets, I have noticed from your CV that you are one of the wise men who advise MTS. I sit on the Board of the London Stock Exchange and currently, as you will know, we are proposing a merger with Boursa Italiana. I just thought I would mention that before we started, because it does seem to me to bear on reform structure, while we are at it. Can I get you to talk about what you have been doing in the function of European Capital Markets?

  Professor Portes: I can talk at great length, My Lord Chairman, about MTS, but I shall not; perhaps on another occasion. I was involved as President of the Wise Men Committee in adjudicating on the matter of the Citigroup operations on MTS in August 2004, which raised quite a ruckus at the time and triggered investigations by the various supervisory authorities, including the FSA, which ultimately fined them its largest single fine and the Wise Men Committee also imposed sanctions. I learned in that exercise quite a lot about how the government bond markets operate. I should say that the euro has had a tremendously positive effect on the functioning government bond markets in Europe, i.e. minus the function of corporate bond markets; let me take the two in turn. The smaller countries, in particular, now find that their bond markets are much more liquid than they were before, they have much more foreign participation, for the simple, obvious reason that they are all now denominated in the same currency. Buying a Finnish bond is buying something which is denominated in euros without the currency risk that you would take, as a member of another Euro Area country, resident in another Euro Area country, if you were to adopt a Finnish bond denominated in markka before 1999. The smaller countries have benefited, as I say, enormously from this, and the result is that if you look at the functioning of the European government bond market, the Euro Area government bond market, now, in some respects it compares quite favourably with the US Treasury market. I will not go into details there, but the Treasury's market is the model for how a government bond market should operate, and so on and so on. In terms of the efficiency of the way the Euro Area bond markets operate, and in particular the role of the futures market, much more developed, actually, in the Euro Area than in the United States in the government bond markets. Corporate bond markets, we at CEPR did studies last year on both these markets in relation to MiFID and the transparency requirements of MiFID and whether they should be extended to the bond market. We discovered among other things that the spreads in the Euro Area corporate bond market are now lower than those in the US, in the corporate bond market in the United States, and on that criterion, which is a pretty common criterion, what does it cost you, in terms of margins, to trade, the Euro Area corporate bond market is more efficient than in the US. If you look at equities, where you will be very familiar with the transformation that is taking place, it is still a very complicated landscape. If you look at the chart, there is a famous chart, which is put out by FESE, the Federation of European Stock Exchanges, where you can see all the Exchanges and the interconnections among them and their relations with the derivative markets and it looks like a big bowl of spaghetti of different colours, gradually some of the spaghetti is being eaten and that chart is getting a little bit simpler as we go over time, with the gradual consolidation, if you like, of the equity markets. The big obstacle there, as you doubtless recognise, is clearing the settlement and that is a topic which is so arcane in some ways and complex that it is difficult for ordinary people to talk about it. I have no great expertise in it but I do know what the costs are, and that is the biggest single obstacle to rationalising, to expanding equity market activity in Europe, but that is not just the euro area that is throughout the European Union. If you then look at the data on bond issuance, and that sort of thing, since the introduction of the euro, you will find, for example, that two years ago, and since, the Euro Area passed the United States in the issuance of international bonds. In terms of current flow, there is more international bond issuance denominated in euros than in dollars. Nobody would have imagined that before 1999, if anybody had said what would be the effects of the European Union. There has been an explosion of activity in the capital markets and I think in the Euro Area in particular this is bound ultimately to have substantial effects on growth as well.

  Q162  Lord Kerr of Kinlochard: May I ask a follow up from that? I agree, nobody would have predicted the astonishing take-off of the bond market and I hazard a guess that nobody would have predicted either that the location which has done best of all is a market not in the euro zone, i.e. the London market. I would not have predicted that, at the time; would you have?

  Professor Portes: In what sense do you suggest that the London market has done better than the euro one?

  Q163  Lord Kerr of Kinlochard: In terms of places where eurobonds are traded?

  Professor Portes: Yes, that the trading would be concentrated, that would happen mainly here. I think that is right, it was not predicted and certainly I did not predict it. On the other hand, by the way, if we look at the operation of the corporate bond market in the United Kingdom we find that spreads are significantly higher than in the euro area as well. Again, by that measure of efficiency, we see that things are actually operating rather well in the euro area.

  Q164  Chairman: That is astounding. Has the same effect been seen not just in bonds but in fixed interests and derivatives?

  Professor Portes: Derivatives, as I say, the contract on the Bund is the biggest futures contract in the world. It is quite interesting, there is a structural difference in the way in which the US market operates and the way the Euro Area government bond market operates, as I said, in the role of derivatives and the futures markets. Roughly speaking, turnover in the Euro Area government bond market is about one third in the cash market and two thirds in the derivatives market. It is exactly the other way round, it is one third in the derivatives market and two thirds in the cash markets, in the United States. You can make a rather technical argument that this is actually to the benefit of the euro area, that the greater role of the derivatives markets here gives a more efficient market overall. We will see, of course, what happens now that the Chicago Board of Trade and the Chicago Mercantile Exchange are merging; they will become a stronger competitor to Eurex. One thing we have learned over the past decade or so, really I think the first clear evidence of it was in 1997, when LIFFE lost the contract on the Bund, that is to say, the ten-year German government bond futures contract was traded primarily in London, on the London International Financial Futures Exchange, which is now the property of Euronext; within a period of months this business transferred to Frankfurt. This is something that we do not expect in the financial markets, we did not expect anyway; normally liquidity creates liquidity and so it is hard to move liquidity, but in this case it moved very rapidly, and the reason for it was primarily technological. They introduced a better trading system in Frankfurt and everybody realised this and, zap, off went the business, it was cheaper and quicker to do it there. What this shows is that it is not only currencies and all that which matter, the technology is very important now and the technology seems to be even more important as we go forward because of the increasing role of hedge funds in trading in bond markets and their desire, many of them, to do programme trading which involves reacting within I will not say nanoseconds but mere seconds to little tiny changes in prices, or divergences in prices, and trying to arbitrage those away. That means you need very efficient electronic technology to trade, if you want to act that fast, and the Exchanges which have the best technology will get the business. I am not sure that answers your question.

  Q165  Chairman: I was just brooding as to whether it did. It answers my question about that the derivatives growth you would tag directly to the euro zone?

  Professor Portes: I think a good part of it, yes. The business in the main derivatives contracts for euro area government securities has grown enormously. Let me just try to explain why. The basic point is that those derivatives contracts on the German government bond are used as a hedge for all trades in the euro zone. That is to say, if you take a position in Italian government bonds in the cash market you will hedge it against a futures contract in the German government bond, or if you take a position in the French government bonds, it will all be hedged by operating in that futures market. Having a single common security with which to hedge is a great promoter of the efficiency of the market and activity in the cash markets.

  Q166  Chairman: How very interesting. There is a question we usually ask at some point, and it may be that this is the moment. Do you think the euro itself is becoming used increasingly as a reserve currency? It sort of bears on all this.

  Professor Portes: Indeed, and this is something on which I have written, on the international role of the euro. I think I and my former colleague, the current Finance Minister of Greece, wrote the first paper on this issue in 1991 and then my new colleague at the London Business School, Helene Ray, and I published a paper on the subject in 1998, and currently I am working on about three different papers on this. This is about as close to my own research area as you can get, which makes it harder to answer your question because there is too much to say. Let me try to boil it down. The role of the euro as an international currency has not been emphasised by the European Central Bank, quite to the contrary, it has played a very hands-off role here, in saying explicitly and at any time you ask that it seeks neither to promote nor to hinder the development of the euro as an international currency. That derives partly from the stance of the Bundesbank in the old days, which resisted the use of the Deutschmark as an international currency, in the belief that this would make monetary policy more difficult, you would lose control of the money supply, and so on. I think that argument and that policy stance are questionable and I am working on that issue currently. The facts so far are that the currencies of the countries going into the Euro Area constituted about 17% of international reserves, Central Bank reserves, at the beginning of 1999, when the transition to the euro came, and now the euro is about 25% of international reserves. The United States dollar is still dominant on reserves. The growth of the euro's role has been primarily at the expense of the yen and sterling and the Swiss franc; the share of the dollar has not fallen very much, if at all, over that period. The reserve currency role, first, is not the only game in town, it is not the only issue, for an international currency. An international currency is also a currency which is the centre of trading in the foreign exchange markets, and there the dollar dominates completely, at least according to the most recent data that we have. Where a currency is traded in only a limited number of markets, the dollar is the standard of reference. If you want to trade between Indian rupees and Brazilian reals you go through the dollar and you do not go through the euro. That may change but that is the state of play right now. On the other hand, in financial markets, as we discussed before, the role of the euro has expanded greatly, and in private financial markets the euro as an asset currency has greatly increased its role since 1999. The euro is an invoicing currency, as far as we can tell, that is to say, in what currency do you bill people, in what currency do Japanese firms send out their invoices to firms in other countries, and the answer is that the role of the euro has been growing significantly, gradually but significantly, say, for Japan, now. Japan's firms used to invoice a lot of their exports to the euro area countries in dollars and now they are invoiced almost entirely in euros, that sort of thing. The future, I think, will be an increased and growing role for the euro, but the euro area central banks and authorities should be very careful about this. If there were a sudden shift of portfolios from dollar-denominated to euro-denominated assets the exchange rate effects would be very powerful, and we are talking about the euro going to $1.40, well, you can see it going a lot higher than that if there was a major shift. We have seen, for example, some of the sovereign wealth authorities, sovereign wealth funds, some of these big, emerging, market capital, big reserve holdings, are putting some of their reserves into special sovereign type of wealth funds which invest in different ways from the central banks. Norway has done this for a long time with its oil money. Singapore has done it for a long time. Now other countries are joining in. Those sovereign wealth funds are looking to diversify and they do not like being so heavily in dollars, and they are shifting, we can observe, to some extent anyway, from dollars to euros. As I say, if that process were to gather speed then the consequences for international financial markets would be very considerable, and not necessarily benign, in terms of exchange rate stability, and so forth, so one has to watch for that. I think the bottom line is that the euro is challenging, in a sense, the dollar in its role as an international currency, in various dimensions; there are a couple of dimensions in which that challenge is not yet apparent, but in a broad range it is, and that is perhaps a cause for celebration in the Euro Area, perhaps not. I think, getting outside your European remit, it may be a cause for concern about the stability of the international financial system. After all, the last time we observed a change in the dollar and currency in the international system was the 1930s, when the dollar took over from sterling. This was only a part of what was going on.

  Q167  Chairman: It was a difficult time; not a happy time.

  Professor Portes: We refer to this sometimes. There is a doctrine, if you like, perhaps that is elevating it too much, but a view, called the hegemonic stability theory, or hypothesis, the idea that you need in international financial markets a hegemon, a dominant currency, in order to ensure stability. If that hypothesis is true we may be in for a rough ride.

  Chairman: Thank you very much. I think that we have just about got time to get through one more question.

  Q168  Lord Inglewood: Moving area, if I may. If we go back to the euro zone, and looking particularly at those countries which are outside it and would like to come into it, how do you feel about the appropriateness of the criteria they have to meet in order to become members?

  Professor Portes: In: that is to say, inappropriate.

  Q169  Lord Inglewood: Exactly, yes. I am being neutral.

  Professor Portes: Estonia could have, and should have, come into the euro area from day one, from 1 May, 2004. It had been anchored to the Deutschmark then the euro in a currency board system since June of 1992 without any hint of currency instability whatsoever. There was no reason why Estonia—it had, in that sense, demonstrated its capacity to take a single monetary policy, in fact, the single monetary policy of the European Central Bank, since 1999, because, effectively, for all practical purposes, the kroon was the euro, and still is. Estonia does not have an independent monetary policy because its currency is anchored through a currency board to the euro, so it could have gone in straightaway. The broader issue, which many of us pointed out well before this all came up, is that the conjunction of the inflation criterion and the exchange rate stability criterion is very difficult to meet because countries which are growing relatively fast, as these countries are, relative to the euro area countries, are catching up. All that we know about that process suggests that these countries will have to have some degree of real exchange rate appreciation, and there are only two ways in which that can come about. Either their nominal exchange rate appreciates, and this is what was happening in Poland, for example, for quite a while, and then they violate the exchange rate stability criterion, or the other way you can get real exchange rate appreciation, and this is not obvious perhaps to the non-economist but if you consider it, is by having a faster rate of inflation than other countries. The point about real exchange rate appreciation is that it compensates for the differential of productivity growth. Those countries are catching up, they have somewhat faster productivity growth than the euro area countries; you would expect that to be compensated somewhat by an exchange rate appreciation so that their goods did not become ridiculously cheap. If productivity is increasing fast and their exchange rate stays constant, in real terms, then they become hypercompetitive. You do not expect to see that happen and indeed one of the problems we are having with China now is that China is not having the rate of inflation that you would expect it to have in order to compensate for this fast productivity growth, with a fixed exchange rate. In a sense, it is the opposite side of that which happens in these countries which are catching up; with flexible exchange rates, if you try to keep the exchange rates within the ERM II sort of band then you would expect to have higher inflation, and so it is very hard to satisfy those two criteria at the same time. I will not get into the question of whether the Maastricht criteria themselves make economic sense, but that is a different issue. I am just saying it is harder for these countries.

  Q170  Lord Inglewood: If you were given the job of refining these criteria, how would you jump?

  Professor Portes: I think I would go with the inflation criterion, and there are various ways you can adjust it. It is an unrealistically tight criterion in the way it is framed as well, because it is the average of the inflation rates in the three lowest inflation countries, not in the Euro Zone, in the EU. What is it right now, is it Sweden that has got this—this is slightly absurd, more than slightly absurd actually, and that does not make sense, but that was formulated, of course, at a time when it was thought that all the countries would be in the monetary union, but it has not turned out that way. That is the criterion I would look at. There are various ways you could give it more flexibility and I think it should have more flexibility.

  Chairman: Thank you very much, Professor. Colleagues, what have we not asked?

  Q171  Lord Kerr of Kinlochard: I would like to ask just one, about the stability of the whole system. I am smarting from what Professor Portes has just said about the Maastricht criteria. I am going to retaliate by saying I remember him, in the mid nineties, I think, or perhaps early nineties, being pretty strong on the exogenous shock theory. I remember being quite strong on it myself. The exogenous shock theory has gone out of fashion. Brent crude at $78, that looks quite like a shock, with differential effects. The system, although it has not yet had the labour market reforms, and it does not have and it is not going to have a big fiscal flywheel, seems to be stable: would you comment on that? To ask what you would have expected, had you been looking from, 1995 or thereabouts, is a bit silly, because very few of us would have predicted quite how many would join EMU from the start; but how has its fragility/stability worked out compared with your expectations?

  Professor Portes: I can remember very clearly discussions in the mid 1990s and even closer to 1999, suggesting it was all going to end in tears very quickly and there would be speculation. Indeed, the Chief Economic Adviser to the Department of Trade and Industry, who had just stepped down, wrote a well-known pamphlet, given great publicity, saying George Soros will be there and the speculators will bring it down within months of January 1999. Of course, this was nonsense, as some of us did point out at the time, but I can remember quite a number of meetings in the City saying "It can't work; the legal obstacles, the technical obstacles, running a counter monetary policy, is so difficult, with all these different monetary policy systems in different countries and institutions, and a single payments area." My goodness, payments systems are so complicated, how can they possibly put them all together at the same time. It worked out rather differently, and every time I see a new pamphlet of this kind, and doubtless some of you will have seen something which came out from the Centre for European Reform, of all places, in the autumn, which talked about the high risks of a break-up of the euro area.

  Q172  Lord Kerr of Kinlochard: ...It was worry about Italy, and bond markets, wasn't it?

  Professor Portes: I think the chances of a break-up of the Euro Area are minimal, not zero; treaties have been abrogated in the past. This is, after all, a treaty; you do not just walk out and say, "Bye-bye, actually I want to go back to my own currency now." This is a rather more formal obligation than that and it has huge political dimensions to it which I think countries would not lightly violate. On political grounds, I think that the break-up of the euro zone, or an exit from the euro zone by any country in it, is extremely unlikely; on economic grounds. I do not think it would be particularly warranted either. It is true that the economics literature, I did not contribute to this literature myself, I hasten to say, did have quite a lot in the mid 1990's about the risk of asymmetric shocks when a particular outside event, like a rise in the price of oil, would affect different countries in the zone differentially. Normally they would want to have different monetary policies and exchange rate policies, or exchange rate flexibility, to react to that shock, and they could not, so there would be tensions, and that would be exacerbated by the absence of labour market flexibility and the absence of a fiscal redistributive system, and so forth. First of all, all that is based on economic analysis, for which its author, Professor Robert Mundell, got a Nobel Prize, but nevertheless it was economic analysis which was done at the beginning of the 1960s when we did not have open capital markets. That is a huge difference, a huge difference. The capital markets have provided a lot of the missing flexibility which labour market adjustment or fiscal federalism was called upon to provide before you had open capital markets. That is the first point. We do have much more of a range of adjustment than was originally discussed, and it was not really discussed much in the mid nineties either. The second is, which was unexpected as well, there is a greater degree of labour market flexibility in practice than people expected simply looking at migration patterns among the euro area countries. Why? Because, the same reason that we have had a remarkably flexible labour market for the past several years: immigration from outside; in the Spanish case, from North Africa, and Rumania and Bulgaria actually too. The Spanish labour market has been much more flexible over the past several years than anybody expected, because they have had migration, so they have been able to accommodate this boom, about which everybody said "Oh, it can't last." To some extent that may be true, but so far so good, and part of that has been facilitated by the availability of labour resources. Here was Spain with a high unemployment rate, that unemployment rate has come down very radically, and at the same time they have been importing workers to do the jobs that Spanish workers do not want to do, just as we have been importing Polish builders, and so on. The conclusion I would come to is that there is more labour market flexibility in practice than was expected when the original discussions of these things took place. To sum up, I do not think that the euro and the single monetary policy have imposed constraints on countries and economies that those economies will be unable to bear. Italy has big problems. Italy would have had big problems without monetary union. We can hope that, in fact, the constraints imposed by monetary union will push Italy to resolve those problems, as, to some extent, clearly, they have pushed Germany.

  Chairman: Thank you very much. You have given us most generously of your time. It was a terrific experience. Thank you very much indeed for coming.
