In order to prevent this from happening, investors would withdraw their savings from the affected banks and sell their government bonds immediately. Therefore countries leaving the Euro would face a situation of significant capital outflows or capital flight. These capital outflows would dent investor confidence and may limit the ability of the affected banks to lend money due to liquidity shortage. This ultimately will result in lower economic growth.
