Foreign Aid Without Cost: Monetary Sovereignty, Sterling Tradability, and the Real Economics of UK International Assistance

Foreign aid is universally framed as a fiscal burden on donor states, requiring higher taxation, borrowing, or reduced domestic expenditure. This paper challenges that premise for countries that issue their own internationally traded currencies. Focusing on the United Kingdom and sterling, we show that foreign aid paid in domestic currency does not necessarily constitute a transfer of real resources from the donor economy. Under identifiable monetary and market conditions, such aid functions primarily as an external monetary injection, expanding offshore currency holdings rather than displacing domestic activity. Drawing on Modern Monetary Theory (MMT), international monetary theory, and a constraint-based approach to inflation, we argue that well-designed sterling-denominated aid is macroeconomically neutral or positive for the UK, while supporting global development and financial stability. The analysis reframes foreign aid from a budgetary sacrifice into a tool of monetary circulation and capacity management. This is a preprint of a manuscript to be submitted to the Cambridge Journal of Economics.
