jens thomsen : european bond markets before and after the euro speech by mr jens thomsen, member of the board of governors of the national bank of denmark and chairman of the efc - subcommittee on eu government bonds and bills markets, at the european government bond summit, brussels, 25 october 2006. * * * my remarks will focus on reflections related to the integration process that the european bond markets has experienced in the post - emu era. in particular, i will highlight the successful evolution of european government bond markets following the introduction of the common currency. the establishment of the european monetary union on january 1, 1999, paved the way for a more integrated european bond market. in the pre - emu era, different euro area countries'government bond yields differed substantially. as an example, yield spreads against germany in the 10 - year government bond segment ranged up to 700 bp in the 1990's ( see slide 1 ). yield spreads were however expected to decline along with the introduction of the euro primarily due to the elimination of exchange rate risk. prior to 1999, attempts were made to anticipate the magnitude of the post - 1999 yield spreads between emu member states. sparsely evidence from other currency areas provided some insight in relation to such anticipations. the provincial bond market in canada was one such candidate area to use for comparison as the canadian provinces had some similar characteristics to the forthcoming emu countries, including no explicit rules for mutual or federal bail out. the spreads between bonds issued by different canadian provinces and canadian government bonds were much lower than euro area spreads prior to the euro ranging " only " up to 60 bp. notwithstanding declining spreads, the canadian evidence indicated that the euro area spreads would not completely disappear ( see slide 2 ). 1 considering the post - 1999 era in retrospect, the euro area spreads have indeed declined significantly since the introduction of the euro ( see slide 3 ). in fact, euro area spreads are small today and actually lower than the ones observed between canadian provinces. this may be due to a higher level of liquidity in the emu countries'issues as well as somewhat better credit ratings among emu countries. regarding the credit ratings, they may be influenced by the generally larger tax bases of central governments in addition to lower labour mobility in europe which causes tax bases to be more secure. the convergences of yields among euro area countries have not yet been observed as markedly for the 10 new eu member states even though erm2 members clearly have experienced lower spreads

the pricing of fixed income instruments. the emergence of a liquid swap curve has thereby served to further alleviate the issue of fragmentation in the european fixed income. the small yield spreads that still exist today between emu member states are primarily attributable to differences in liquidity and credit risk between issuers. consequently, the emu era has drawn more attention to these two factors. regarding credit risk, increased focus may have served to increase the disciplinary effect of the financial markets on policy makers. an inspection of the relationship between the development of national debt - to - gdp ratios and sovereign yield spreads relative to germany 1999 a€ “ 2006, indicates that the improved creditworthiness of the emu member states since 1999 can explain some of the decline in the spreads ( see slide 10 ). however, credit risk is only one of the factors that determine the size of the spreads and should therefore not be viewed in isolation. in order to examine the role of respectively credit risk and liquidity embedded in the current yield spreads across emu countries, one may use prices on credit default swaps ( cds ) to split up the yield spread between credit risk and liquidity. the fact that the price of a cds approximately equals the credit risk premium of the underlying bond makes this possible. under the assumption that the yield spread between the emu - members purely can be explained by differences in credit risk and liquidity, the liquidity risk premium may be defined as the residual of the yield spread after deducting the credit risk premium ( see slide 11 ). the calculation shows that the yield spreads today only are affected noticeable by credit risk for greece, italy and portugal, whereas liquidity primarily plays a role for the smaller issuers. in addition to the government bond market, the introduction of the euro also formed expectations concerning a development of the euro - denominated corporate bond market. though this market has increased fairly much in terms of total outstanding in the post - 1999 period, the corporate bond market continues to account for a small fraction of the euro - zone debt market ( see slide 12 ). corporate finance traditions in europe favouring the banking model may be one explanation for this. it should be recognised that well developed mortgage markets make a strong contribution to debt security markets in a number of european countries. nevertheless, an increasing number of entities outside the euro - zone issue bonds denominated in euro. indeed, the role of the euro in the international debt security markets has increased substantially since 1999. for broadly defined
