Abstract
This paper examines whether the efficiency market hypothesis for the Greek sovereign debt holds. As in Blanco et al. (2005) we test the theoretical equivalence of credit default swap (CDS) and spreads that dictates a cointegration relationship between the two. The main innovation of the present analysis is the use of a threshold vector error-correction (TVECM) model, thus allowing thresholds within the sample covering the period 1990-2010. Moreover, by employing this methodology we are able to evaluate the degree and dynamics of transaction costs resulting from various events due to external market imperfections but also domestic factors. The main hypothesis we test is to what extent spreads and CDS are indeed integrated that may result in an efficient and integrated segniorage capital market. Our findings support the gradual integration hypothesis. We find that spreads and CDS are cointegrated, though threshold effects are also revealed in terms of events that have impacted on markets.

5. Conclusions and Policy Implications
Over the past year, euro area sovereign yields have exhibited an unprecedented degree of volatility. In March 2009 the spread between the yield on a 10-year Greek government bond and the yield on a German Bund of equivalent maturity was as high as 280 basis points (bp). By September 2009 the same spread had dropped below 120 bp. In January 2010, it had climbed back up to over 380 bp. Alas, in April 2010 the spread reach 670 bp only to climb even higher to the level of 1287 bp in May 2010, the month that Emergency Financing Mechanism and the memorandum of
understanding regarding policy conditionality, a joint initiative of the IMF, the EU Commission and the ECB were signed.
The goal of this paper was to examine whether there is a cointegration relationship between CDS and spreads of Greek sovereign bonds. We employed the threshold cointegration analysis of Hansen and Seo (2002). This methodology allows for regime shifts over the sample period and by doing so it would give us an opportunity to show whether the arbitrage relationship expected by the literature is subject to thresholds effects. The regime shift could occur in the intercept, trend or the entire cointegration vector. The main hypothesis we tested was to what extent spreads and CDS were indeed integrated that may result in an efficient and integrated segniorage capital market. The TVECM model has the advantage of allowing thresholds within the sample covering the period 2003-2010.
Our findings support the gradual integration hypothesis. Moreover, we found that spreads over swaps and CDS were cointegrated and two regimes were identified. This implies that a threshold exists and it is indeed significant. Thus, adjustment costs in the error correction are present, and they are valid at the typical regime one that is the dominant, and as a result should not be ignored.
