The DFI Transparency Index  assesses both sovereign and non-sovereign lending by DFIs. In the case of sovereign lending, our assessment is limited to leading multilateral DFIs, while assessment of non-sovereign lending includes both multilateral and bilateral DFIs. For multilateral DFIs that conduct both sovereign and non-sovereign activities we assess each separately.

While we assess both forms of lending, our analysis and ranking separate sovereign and non-sovereign lending. This is a result of our recognition that the two types of lending involve significantly different business models and, as such, necessitate the disclosure of different types of information. As the DFI Transparency Tool varies across the two types of lending, and the DFI Transparency Index includes different indicators in line with the tool, it is necessary to weigh the constituent indicators differently. With this in mind, we conduct two rankings.
