In a number of countries, especially emerging market economies, the public sector has in recent years been accumulating sizeable cross-border financial assets, mainly in the form of official foreign exchange reserves. World reserves have risen from USD 1.2 trillion in January 1995 to above USD 4 trillion in September 2005, growing particularly rapidly since 2002. This paper investigates the features, drivers, risks and costs of such recent reserve accumulation, as well as the other uses that certain countries have been making of their accumulated foreign assets. The main trends in central bank reserve management are also reviewed. Finally, the paper provides some evidence for the impact of reserve accumulation on yields and asset prices.

The paper analyses whether, and to what extent, emerging market economies (EMEs) have systemic importance for global financial markets, above and beyond their influence during crises episodes. Using a novel database of exogenous economic and political shocks for 14 systematically relevant EMEs, we find that EME shocks not only have a statistically but also economically significant impact on global equity markets. The economic significance of EME shocks is in particular underlined by their remarkably persistent effects over time. Importantly, EMEs are found to influence global equity markets about just as much in "good" times as in "bad" times, i.e. during crises or periods of financial turbulence. Finally, we detect a large degree of heterogeneity in the transmission of EME shocks to individual countries' equity markets, stressing the different degrees of financial exposure, which is relatively higher for European equity markets.
