Integration of European bond markets

I investigate the time variation in the integration of EU government bond markets. The integration is measured by the explanatory power of European factor portfolios for the individual bond markets for each year. The integration of the government bond markets is stronger for EMU than non-EMU members and stronger for old than new EU members. For EMU countries, the integration is weaker the lower the credit rating is. During the recent crisis periods, the integration is weaker, particularly for EMU countries.     

Systemic and Idiosyncratic Risk in EU-15 Sovereign Yield Spreads after Seven Years of Monetary Union

The market capitalisation of international bond markets is much larger than that of international equity markets. However, compared to the large body of literature on international equity market linkages, there are far fewer empirical studies of bond systemic risk or international bond market co-movements. The extent of international bond market linkages merits investigation, as it may have important implications for the cost of financing fiscal deficit, monetary policymaking independence, modelling and forecasting long-term interest rates, and bond portfolio diversification. In this paper, we investigate the relative influence of systemic and idiosyncratic risk factors on yield spreads over 10-year German government securities during the seven years after the beginning of Monetary Integration. We estimate both panel regressions for the two groups of EU-15 countries (EMU and non-EMU) and specific-country regressions for the nine countries in the EMU group and the three countries in the non-EMU group. All estimations include both domestic (differences in market liquidity and credit risk) and international risk factors. The results present clear evidence that it was mostly idiosyncratic rather than systemic risk factors that drove the evolution of 10-year yield spread differentials over Germany in all EMU countries during the seven years after the beginning of Monetary Integration. Conversely, in the case of non-EMU countries, adjusted yield spreads (corrected from the foreign exchange factor) are influenced more by systemic risk factors. The fact that these countries do not share a common Monetary Policy might explain these results, which may show that government bonds from EMU countries have a better safe-haven status that those of non-EMU countries.     

Have the GIPSI settled down? Breaks and multivariate stochastic volatility models for,and not against,the European financial integration

We investigate the integration of the European peripheral financial markets with Germany, France, and the UK using a combination of tests for structural breaks and return correlations derived from several multivariate stochastic volatility models. Our findings suggest that financial integration intensified in anticipation of the Euro, further strengthened by the EMU inception, and amplified in response to the 2007/2008 financial crisis. Hence, no evidence is found of decoupling of the equity markets in more troubled European countries from the core. Interestingly, the UK, despite staying outside the EMU, is not worse integrated with the GIPSI than Germany or France.     

Unraveling the Financial Contagion in European Stock Markets During Financial Crises: Multi-Timescale Analysis

The article investigates the evidence of financial contagion and market integration in selected European equity markets during nine major crises across regions. The focus is to identify whether (i) contagion evidence is pure or fundamental and (ii) dynamic evolution of integration is in the short run or long run. Wavelet decomposition in both its discrete and continuous forms is used. The findings reveal the following: (i) prior to the subprime crisis, contagion effects generated short-term shocks. The most recent US subprime crisis, however, reveals the evidence of fundamental based contagion. (ii) We find increasing short-run and long-run stock market integration, driven by several stages of the establishment of Economic and Monetary Union (EMU), questioning the ultimate benefits of formal entry into EMU membership.     

Volatility‐Spillover Effects in European Bond Markets

Volatility spillover from the US and aggregate European bond markets into individual European bond markets using a GARCH volatility‐spillover model is analysed. Strong statistical evidence of volatility spillover from the US and aggregate European bond markets is found. For EMU countries, the US volatility‐spillover effects are rather weak (in economic terms) whereas the European volatility‐spillover effects are strong. The bond markets of EMU countries have become much more integrated after the introduction of the euro, and in recent years they have become close to being perfectly integrated. The main driver of the integration appears to be convergence in interest rates.     

The determinants of the volatility of returns on cross-border asset holdings

Using both panel and cross-sectional models for 28 industrialized countries observed from 2001–2009, we report a number of findings regarding the determinants of the volatility of returns on cross-border asset holdings (i.e., equity and debt). Greater portfolio concentration and an increase in assets held in emerging markets lead to an elevation in earning volatility, whereas more financial integration and a greater share held in Organization for Economic Cooperation and Development countries and by the household sector cause a reduction in the return volatility. Larger asset holdings by offshore financial corporations and non-bank financial institutions cause higher market volatility, although they affect volatility in the equity and bond markets in the opposite way. Overall, both panel and cross-sectional estimations provide very similar results (albeit of different magnitude) and are robust to the endogeneity problem.     

Measuring bilateral spillover and testing contagion on sovereign bond markets in Europe

The global financial crisis rapidly spread across borders and financial markets, and also distressed EU bond markets. The crisis did not hit all markets in the same way. We measure the strength and direction of linkages between 16 EU sovereign bond markets using a factor-augmented version of the VAR model in Diebold and Yilmaz (2009). We then provide a novel test for contagion by applying the multivariate structural break test of Qu and Perron (2007) on this FAVAR detecting significant sudden changes in shock transmission. Results indicate substantial spillover, especially between EMU countries, with Belgium, Italy and Spain being key markets during the financial crisis. Contagion has been a rather rare phenomenon limited to a few well defined moments of uncertainty on financial assistance packages for Greece, Ireland and Portugal. Most of the frequent surges in market co-movement are driven by larger shocks rather than by contagion.     

International income risk-sharing and the global financial crisis of 2008–2009

We examine the impact of the global financial crisis on the degree of international income and consumption risk-sharing among industrial economies using returns on cross-border portfolio holdings (e.g., debt, equity, FDI). We split the returns from the net foreign holdings as receipts (inflows) and payments (outflows) to investigate which of the two sides exhibited the greater resilience for income risk-sharing during the recent crisis. First, we find that debt delivered better risk-sharing than equity, mainly reflecting the deficit deterioration in EMU countries during the post-crisis period. FDI, by contrast, did not correspond to noticeable risk diversification. Second, separating output shocks into positive and negative components reveals that debt holding receipts (equity liability payments) performed better under negative (positive) realizations of the shock variable. Third, the unwinding of capital flows resulted in a sharp fall in income dis-smoothing via the debt liability channel in the new EU countries.     

Time varying integration of European stock markets and monetary drivers

This study analyzes time-varying integration of stock markets among fourteen European countries and its monetary drivers relevant to the two contrasting events — the introduction of Euro in 1999 and banking crisis of GIIPS in 2011. Our panel analysis reports evidence that monetary performance convergence, lower differentials in interest rates and inflation among EU countries, has been a key driver for the increase in integration of EU stock markets post EMU. Our qualitative analysis indicates that post EMU, the GDP differences among the EU countries have reverse relations with monetary performance convergence. This finding is in line with those of our quantitative study with a price-based indicator for integration.     

Capital Market Integration in the Middle East and North Africa

This paper studies capital market integration in Middle Eastern and North African (MENA) countries and its implications for international portfolio investment allocation. Starting with four cointegration methodologies, we significantly reject the hypothesis of a stable, long-run bivariate relationship between each of these markets and the European Monetary Union (EMU), the United States, and a regional benchmark. This indicates the existence of significant diversification opportunities for three categories of investors (EMU, world, and regional investors). A recursive analysis based on Barari (2004) suggests that recently, the MENA markets have started to move toward international financial integration. Investigating the effect of selected financial, economic, and political events on such a process, we extend the methodology and find that the markets react heterogeneously to the different categories of shocks. They should therefore not be treated as a bloc for global allocation purposes. Finally, after adjusting the integration levels by relative market capitalization, Israel and Turkey are the most promising markets in the region, followed by Egypt, Jordan, and Morocco. Tunisia and Lebanon seem to be lagging behind.     

International spillover effects of unconventional monetary policies of major central banks

This study examines the effects of unconventional monetary policies (UMPs) by the major central banks, namely the Bank of England (BOE), Bank of Japan (BOJ), European Central Bank (ECB) and the Federal Reserve (Fed), on the international financial markets, taking global spillovers and monetary policy interaction into account. To this end, we applied the Global Vector Autoregressive (GVAR) model to 35 countries/economies and one region for the period from March 2009 to July 2019. In addition, we accommodated the smooth transition to the GVAR to consider possible structural changes in the effects of UMPs and monetary policy interaction. Our results indicate the importance of capturing structural changes, showing the remarkable difference between the beginning and end of the sample. For example, we found clear evidence of monetary policy coordination after the global financial crisis and less evidence of policy interaction in the recent period. Also, our results suggest that generally, the UMPs of the major central banks had stronger effects on both domestic and international bond markets in the earlier period. In contrast, the global equity markets responded more positively to the UMPs in the recent period, although there was no noticeable difference in the responses of domestic equity markets throughout the sample.     

Assessing Bond Market Developments Pot-Euro

As a result of global trends in the financial industry, European financial markets are in the midst of a major transformation, and Economic and Monetary Union (EMU) is acting as a primary catalyst for such change. Over time financial integration will provide European markets with sufficient liquidity and scale to turn them into effective rivals of the U.S. markets.
This paper provides a framework for assessing the likely consequences of EMU for the evolution of European bond markets. First, it discusses broad fundamental shifts in international capital flows and how EMU is expected to affect them. Second, it analyzes in some detail the two most important portfolio shifts expected to accompany Monetary Union: potential changes in currency reserves held by central banks and diversification of international investors' portfolios. Third, it considers the possibility that the asset management industry and households' increased appetite for risk will lead to a major shift on the demand side. On the supply side, it explores the likely effect of Monetary Union on government bond yield spreads and expected changes in the key pricing factors.
The paper concludes with an overview of the considerable growth prospects for the European corporate bond market. In the Euromarket, which has traditionally been the preserve of borrowers of high credit standing, there have already been signs of increased interest in corporate issues, particularly lower-rated ones. The search for higher yields by investors, greater expertise in analyzing credit risks by institutional investors, and reduced issuance in European government bond markets will combine to spur growth in the European corporate bond market. As a consequence, the traditional bank-oriented relations will clearly weaken, and more companies will find opportunities to raise capital and obtain financing at lower cost.     

Evolution of international stock and bond market integration: Influence of the European Monetary Union

This paper examines the dynamic relationship between daily stock and government bond returns of selected countries over the past decade to infer the state and progress of inter-financial market integration. We proceed to empirically investigate the influence of the European Monetary Union (EMU) on time variations in inter-stock–bond market integration/segmentation dynamics using a two-step procedure: First, we document the downward trends in time-varying conditional correlations between stock and bond market returns in European countries, Japan and the US. Second, we investigate the causality and determinants of this interdependent relationship, in particular, whether the various macroeconomic convergence criteria associated with the EMU have played a significant role. We find that real economic integration and the reduction in currency risk have generally had the desired effect on financial integration but monetary policy integration may have created uncertain investor sentiments on the economic future of the EMU, thereby stimulating a flight to quality phenomenon.     

The impact of the euro on Europe's financial markets

This paper presents an overview of the impact of the introduction of the euro on Europe's financial structure over the first four years since the start of EMU. It analyzes changes in money markets, bond markets, equity markets and foreign exchange markets. Euro's role in originating or catalyzing trends has been uneven across the spectrum of financial markets. From the supply side, banks and investors in fixed income markets have become more focused on the characteristics of individual borrowers rather than the nationality of the issuer and have built up expertise to evaluate credit risk. European equity markets have also been affected by the enhanced ability of investors to build strategies with a pan‐European perspective as prices increasingly reflected risk factors specific to industrial sectors rather than individual countries. On the borrower side, EMU has increased the attractiveness of market‐based financing methods by allowing debt issuers to tap institutional portfolios across the euro area. Lower barriers to cross‐border financial transactions have also increased the contestability of the market for financial services, be it at the wholesale or the retail level. The introduction of the euro has also highlighted the shortcomings of existing institutional structures and areas where excessive focus on narrowly defined interests may stand in the way of realizing the full potential benefits from the new environment. Diverging legal and institutional infrastructures and market practices can impede further financial market development and deepening. Hence, the euro has put a premium on cooperation between national authorities and institution as a means of achieving a more harmonized financial environment. The impact of EMU on depth in foreign exchange markets has been less clear‐cut, as volatility, spreads, trading volumes and liquidity appear not to have changed in a substantial way. Overall, it seems that the new currency has made some progress towards the goal of becoming a currency of international stature that would rival that of the US dollar. However, a number of the necessary next steps towards achieving this goal are also among the trickiest to implement.     

Asian financial integration: Global or regional? Evidence from money and bond markets

This paper investigates the degree of global versus regional financial integration in Southeast Asia during the period 2004–2012. We examine integration in the money and bond markets in Asia by employing a covered-interest-parity-based measure of financial integration. The impact of the 2008 financial crisis as well as the recent regional bond initiatives on the integration process of Asian money and bond markets respectively are specifically investigated. Empirically, we adopt the Phillips and Sul (2007) convergence methodology that has not been previously employed to examine the integration process in Asian money and bond markets. We find evidence of both global and regional integration in the money market pre 2008 but once the crisis hit, the process of global integration comes to an abrupt halt. However, regional integration, albeit at a slower pace, is still clearly evident in the post-crisis period. As for the Asian bond market, evidence of both global and regional integration is found but, in comparison, the latter is more convergent post 2008. Regional integration is stronger when interest rates with longer maturity are considered. In addition, we identify some convergent subgroups of countries and this suggests that a multi-tiered style of convergence is present.     

Financing the green projects: Market efficiency and volatility persistence of green versus conventional bonds,and the comparative effects of health and financial crises

The establishment of the green bond market is an attempt to attain environmental sustainability from the finance perspective. One of the factors that could either hinder or promote this course is the degree of market efficiency of the market. Against this background, this study comparatively examines the market efficiency of the U.S. green and conventional bonds. In addition, the performance of both markets is investigated during global health and financial crises. Applying the fractional integration technique, we find that the overall green and conventional bonds markets are still inefficient, indicating that green and conventional investors can make excess gains by predicting the future trends of bond prices. There is also evidence that the green bond market exhibits higher volatility persistence during the global health crisis than during the global financial crisis. These findings are corroborated by the GARCH-based models, whose results show that volatility shocks are more persistent in the green bond market during the health crisis than during the financial crisis. However, the conventional bond market observes persistence in volatility shocks during both events. Towards sustainable environment goals, these results have relevant implications for green investors and policy makers.     

On cross-border bank credit and the U.S. financial crisis transmission to equity markets

This paper examines the role played by cross-border equity, bond and bank credit flows versus international trade in the transmission of the U.S. financial crisis to equity markets worldwide. We estimate vector autoregressive models with exogenous global factors using monthly data on 36 emerging and developed countries. The results from an eclectic methodology that includes causality tests, generalized impulse responses and forecast error variance decompositions indicate that the crisis is mostly transmitted through bank credit rather than portfolio flows and international trade. The results are robust to altering the exogenous versus endogenous vectors of variables, to measuring equity prices in U.S. dollars or local currency, to averaging the data across countries versus averaging the parameters from individual country estimation, and to redefining the start date of the crisis. The findings endorse the use of banking regulation and capital controls as part of the policy toolkit to limit financial vulnerability.     

Leverage Constraints and the International Transmission of Shocks

Recent macroeconomic experience has drawn attention to the importance of interdependence among countries through financial markets and institutions, independently of traditional trade linkages. This paper develops a model of the international transmission of shocks due to interdependent portfolio holdings among leverage‐constrained investors. In our model, without leverage constraints on investment, financial integration itself has no implication for international macro comovements. When leverage constraints bind, however, the presence of these constraints in combination with diversified portfolios introduces a powerful financial transmission channel that results in a positive comovement of production, independently of the size of international trade linkages. In addition, the paper shows that with binding leverage constraints, the type of financial integration is critical for international comovement. If international financial markets allow for trade only in noncontingent bonds, but not equities, then the international comovement of shocks is negative. Thus, with leverage constraints, moving from bond trade to equity trade reverses the sign of the international transmission of shocks.     

Assessing the impact of an EU financial transactions tax on asset volatility: An event study

Under the context of EMU debt and financial crisis, we assess the impact of EMU's announcement of a Financial Transactions tax (FTT) on bond and equity volatilities for seven countries, namely Germany, France (core EMU), Greece, Italy, Ireland, Portugal and Spain (periphery EMU). In the absence of historical data on volume and volatility of transactions of such a tax, we utilize the event study methodology. The selected event date considering the FTT announcement was found significant for core EMU's equity portfolio and periphery EMU's bond portfolio. Moreover, under GARCH models, we found that the announcement effect of FTT increases the volatility of both core EMU's equity portfolio as well as periphery EMU's bond portfolio.     

Financial Integration in Asset and Liability Holdings in East Asia

In this article, we examine the evolution of intra-East Asian financial integration from 2001 to 2013. Most existing studies on this topic look primarily at asset holdings; we examine liability holdings as well. Using the International Monetary Fund’s Coordinated Portfolio Investment Survey data for equities, long-term debt, and short-term debt, our analysis generally supports the conventional wisdom that East Asian countries are more financially integrated with global financial centers than they are with each other. This is true for both asset holdings and liabilities and is confirmed by an econometric analysis based on financial gravity equations. However, the gap between global integration and regional integration has narrowed for asset holdings over time but not for liability holdings. The results of additional econometric analysis indicate that diversification of liability holdings can mitigate financial instability due to global financial shocks. More precisely, diversification was associated with smaller exchange rate depreciation during the quantitative easing taper tantrum of 2013. These results point to a possible benefit from strengthening regional financial integration. Deeper regional integration would reduce dependence on global financial markets for funding and hence vulnerability to global shocks.
