Three Essays on Information, Volatility, and Crises in Equity Markets


Book Description

Essay 3 investigates the relation between proxies for investor sentiment and stock market crises and recoveries on international indices. Using an Early-Warning-System (EWS) model, the essay examines whether investor sentiment is a useful predictor for the occurrence of stock market crises and early signs of recovery. Three alternative proxies are used to measure investor sentiment, including previously cited measures of stock market riskiness, investors' risk aversion and investors' optimism about stock markets. The results show that investor sentiment is overall a significant predictor of the occurrence of crises within a one year period, and that the addition of sentiment into early warning signal models of stock market crises can improve the predictive performance of the model (increases in investor sentiment increase the probability of occurrence of a crisis, which is in line with previous contributions finding a negative lead-lag relation between sentiment and stock returns). The extension of the model to early signs of recoveries also shows that sentiment is a reliable predictor. The measure of stock market riskiness (Baker and Wurgler, 2006) is found to be a better predictor than the Volatility Index (VIX) and the Put-to-Call Ratio (PCR). The cross-country comparison results confirms the literature findings that the link between sentiment and stock market returns varies across indices and cultures, as the predictive power of the variable appears strongest in the French and U.S. indices.




Emerging Capital Markets and Globalization


Book Description

Back in the early 1990s, economists and policy makers had high expectations about the prospects for domestic capital market development in emerging economies, particularly in Latin America. Unfortunately, they are now faced with disheartening results. Stock and bond markets remain illiquid and segmented. Debt is concentrated at the short end of the maturity spectrum and denominated in foreign currency, exposing countries to maturity and currency risk. Capital markets in Latin America look particularly underdeveloped when considering the many efforts undertaken to improve the macroeconomic environment and to reform the institutions believed to foster capital market development. The disappointing performance has made conventional policy recommendations questionable, at best. 'Emerging Capital Markets and Globalization' analyzes where we stand and where we are heading on capital market development. First, it takes stock of the state and evolution of Latin American capital markets and related reforms over time and relative to other countries. Second, it analyzes the factors related to the development of capital markets, with particular interest on measuring the impact of reforms. And third, in light of this analysis, it discusses the prospects for capital market development in Latin America and emerging economies and the implications for the reform agenda.




Global Financial Stability Report, October 2019


Book Description

The October 2019 Global Financial Stability Report (GFSR) identifies the current key vulnerabilities in the global financial system as the rise in corporate debt burdens, increasing holdings of riskier and more illiquid assets by institutional investors, and growing reliance on external borrowing by emerging and frontier market economies. The report proposes that policymakers mitigate these risks through stricter supervisory and macroprudential oversight of firms, strengthened oversight and disclosure for institutional investors, and the implementation of prudent sovereign debt management practices and frameworks for emerging and frontier market economies.




Global Financial Stability Report, April 2021


Book Description

Extraordinary policy measures have eased financial conditions and supported the economy, helping to contain financial stability risks. Chapter 1 warns that there is a pressing need to act to avoid a legacy of vulnerabilities while avoiding a broad tightening of financial conditions. Actions taken during the pandemic may have unintended consequences such as stretched valuations and rising financial vulnerabilities. The recovery is also expected to be asynchronous and divergent between advanced and emerging market economies. Given large external financing needs, several emerging markets face challenges, especially if a persistent rise in US rates brings about a repricing of risk and tighter financial conditions. The corporate sector in many countries is emerging from the pandemic overindebted, with notable differences depending on firm size and sector. Concerns about the credit quality of hard-hit borrowers and profitability are likely to weigh on the risk appetite of banks. Chapter 2 studies leverage in the nonfinancial private sector before and during the COVID-19 crisis, pointing out that policymakers face a trade-off between boosting growth in the short term by facilitating an easing of financial conditions and containing future downside risks. This trade-off may be amplified by the existing high and rapidly building leverage, increasing downside risks to future growth. The appropriate timing for deployment of macroprudential tools should be country-specific, depending on the pace of recovery, vulnerabilities, and policy tools available. Chapter 3 turns to the impact of the COVID-19 crisis on the commercial real estate sector. While there is little evidence of large price misalignments at the onset of the pandemic, signs of overvaluation have now emerged in some economies. Misalignments in commercial real estate prices, especially if they interact with other vulnerabilities, increase downside risks to future growth due to the possibility of sharp price corrections.
