Current trends seem to be leading toward a more fragmented global financial system in which countries rely primarily on domestic capital formation. Sharper regional disparities in the availability and cost of capital could emerge, particularly for smaller businesses and consumers, constraining investment and growth in some countries. And, while a more balkanized financial system does reduce the likelihood of global shocks creating volatility in far-flung markets, it may also concentrate risks within local banking systems and increase the chance of domestic financial crises.
