more than the SDR against the dollar (Chart 1). As for interest rates, the ECU is found to have generally carried the highest (Chart 2). The rates of dollar assets were generally below those of both the ECU and the SDR. In fact, it is only since the end of 1977 that dollar rates have risen to levels similar or even higher than those of the two currency baskets. Finally, when account is taken of the overall yield deriving from interest payments and exchange rate variations, 100 dollars invested in each of these assets at the beginning of 1973 would have produced, at the end of November 1980, 216 dollars, if the investment had been made in assets denominated in ECUs, 204 dollars if in SDRs and 181 dollars if the funds had been held in the US currency (Chart 3). Even when the simulation is extended to the currencies of the two other major countries, the yen and the Deutschemark - the latter of which has the dominant weight in the Community basket - the yield of the ECU appears satisfactory. In fact, during the period in question the performance of investments in these two currencies is found to have been only slightly better than that of an investment in ECUs - respectively 232 and 241 dollars in the previous example but, given the smaller exchange rate variations of the ECU, its use would have better fitted the requirements of lenders and borrowers. If past experience is any guide to the future, the figures given above provide good grounds for believing that the ECU can play a more active and important role in the denomination of both fixed and variable rate bond issues. And this is true not only for the international markets, but also, if suitable forms are adopted, for domestic markets, as is shown, for example, by the success of 1979 ECU-linked loan by San Paolo Bank. Indeed, this bank deserves praise for having included an Italian name in the list of those who have developed financial formulas based on composite units of account, thus opening the way for the new monetary unit born with the EMS to be used in capitai markets. It is obvious, however, that the support for this type of issue in individuai domestic markets must take account of the limits present in the various countries in the form of exchange, monetary and credit controls. Real freedom for ECU securities to be issued and to circuiate must necessarily be set in the framework of a progressive integration of national markets and of harmonization of the existing rules and regulations. The active interest of the monetary authorities in the development of this role of the ECU is confirmed by some projects that are now under consideration. The ECOFIN Council is about to revise and extend the mechanism of Community loans to help member countries overcome balance-of-payments difficulties. It will be possible to arrange such loans, either directly with third countries and financial agencies or in the capitai markets, and to de20
