But although their publicly announced reason for doing so was to provide migrants with cheaper and more reliable services, the underling subtext of such initiatives - also strongly backed by the World Bank and the US Treasury - was to prevent these 'informal' 'underground' networks being used by terrorists and drugs smugglers - even though there was little or no evidence that "hawala" networks were actually being used for such purposes. Most informed commentators concluded that such 'informal' networks provided migrant workers with a service which was easier to access, cheaper, swifter, and if anything even more reliable than those provided by the banks and other former sector agencies.
