Tied aid credits are a way for donors to look to boost the international competitiveness of domestic enterprises while simultaneously contributing to development in recipient countries. Though regulated through the Arrangement on Officially Supported Export Credits, tied aid credits claim a place among the instruments of development policy and are eligible as Official Development Assistance (ODA). This raises the question of whether the international regulatory framework is equipped to safeguard the presumed development goals. This article examines the internal coherence of the tied aid disciplines of the Organisation for Economic Co-operation and Development (OECD) with the development principles coined by the Development Assistance Committee (DAC). Thereby, the extent to which the OECD lives up to its own promise of Policy Coherence for Development (PCD) is scrutinized.
