The rise of supplemental lending at the World Bank

Abstract

AbstractWorld Bank projects sometimes receive supplemental loans months or years after initial project approval. Largely unnoticed, supplemental lending has mushroomed in the last decade, accounting for nearly 30% of all new loans in some years. These loans can serve important functions, as they come without the bureaucratic delays associated with new projects. We argue that supplemental loans are potentially useful foreign policy tools for powerful donors in settings where time is of the essence. Consistent with this, we find that countries receive significantly larger supplemental loans while serving a two‐year term on the geopolitically important United Nations Security Council.
