A Barrel of Oil or a Bottle of Wine: How do Global Growth Dynamics Affect Commodity Prices?

This paper investigates the causes of extreme fluctuations in commodity prices from 1990 to 2010. Analyzing two very distinct commodities-crude oil and fine wine, we find that macroeconomic factors are the main determinants of commodity prices. Although supply constraints have the expected effect, aggregate demand growth is the key factor. The empirical results show that while advanced economies account for more than half of global consumption, emerging economies make up the bulk of the incremental change in demand, thereby having a greater weight in commodity price formation. The results also show that the shift in the composition of aggregate commodity demand is a recent phenomenon.

Gross Private Capital Flows to Emerging Markets; Can the Global Financial Cycle Be Tamed?

This paper assesses empirically the key drivers of private capital flows to a large sample of emerging market economies in the last decade. It analyzes the effect of the global financial cycle, measured by the VIX, on capital flows and investigates the role of fundamentals and country characteristics in mitigating or amplifying its effect. Using interaction models, we find the effect of the VIX to be non-linear. For low levels of the VIX, capital flows are driven by fundamental factors. During periods of stress, the VIX becomes the dominant driver of capital flows while other determinants, with the exception of interest rate differentials, lose statistical significance. Our results also suggest that the effect of global financial conditions on gross private capital flows increases with the host country’s level of financial sector development. Finally, our results imply that countries cannot fully insulate themselves from global financial shocks, unless creating a fragmented global financial system.

Global and Regional Spillovers to GCC Equity Markets

This paper analyzes the impact of global and regional spillovers to GCC equity markets. GCC equity markets were impacted by spillovers from U.S. equity markets despite varying degrees of foreign participation. Spillovers from regional equity markets were also important but the magnitude of the effects were on average smaller than that from mature markets. The results also illustrated episodes of contagion in particular during the recent global financial crisis. The findings suggest that given the degree of openness, and open capital accounts the financial channel is an important source through which volatility is transmitted. In this regard, GCC equity markets are not immune from global and regional financial shocks. These findings refute the notion of decoupling between the GCC equity and global equity markets.

Effects of Capital Flow Liberalization - What is the Evidence from Recent Experiences of Emerging Market Economies?

This paper analyzes the experiences of emerging market economies (EMEs) that have liberalized capital flows over the past 15 years with respect to macroeconomic performance and risks to financial stability. The results of the panel data regressions indicate that greater openness to capital flows is associated with higher growth, gross capital flows, and equity returns and with lower inflation and bank capital adequacy ratios. The effects vary depending on thresholds. As a potential application of these findings, the paper explores the possible effects of liberalization on China by applying the coefficients of explanatory variables to the corresponding variables of China in 2012–16.

Is Credit Easing Viable in Emerging and Developing Economies? An Empirical Approach

During the global financial crisis, many central banks in advanced economies engaged in credit easing. These policies have been perceived as largely successful in reducing stress in financial markets, thus avoiding larger output losses. In this paper, we study empirically whether credit easing is also a viable policy tool to cope with banking crises in emerging and developing economies. We find that credit easing leads to a sharp increase in domestic currency depreciation, high inflation, and a substantial reduction in economic growth in a large panel of emerging and developing economies. For advanced economies, we find the effects to be benign. Our results suggest that emerging and developing economies should be cautious when using credit easing as it may fuel adverse macroeconomic repercussions.

Do Gulf Cooperation Countries' equity markets waltz or tango to spillovers?

This paper analyses the impact of global and regional spillovers to GCC equity markets. GCC equity markets were impacted by spillovers from US equity markets despite varying degrees of foreign participation. Spillovers from regional equity markets were also important but the magnitude of the effects was on average smaller than that from mature markets. The results also illustrated episodes of contagion, in particular during the recent global financial crisis. The findings suggest that the degree of interconnectedness between the GCC and global financial markets, given their longstanding net creditor status, underscores the financial channel as an important source through which volatility is transmitted. In this regard, GCC equity markets are not immune from global and regional financial shocks. These findings cast doubts on the notion among some analysts of decoupling between the GCC and global equity markets.
