This is a legitimate question, especially as some countries have tended to promote the internationalisation of their currency in the past. Such a promotion policy was motivated by several factors, including increased income from seigniorage, easier financing of balance of payments deficits and enhanced opportunities for the development of domestic financial markets. Nevertheless, these potential advantages should not be overrated.
The additional seigniorage revenue generated by the international use of a currency remains limited. For the most widely used international currency, the US dollar, seigniorage originating from the use of the dollar by non-residents is estimated at around 1% of GDP.
