News and announcements
View in News and announcements →- CGD reviews how development banks assess market impact ↗
Reviews public information on 17 institutions’ market-impact methodologies, targets, incentives and reporting. The authors find substantial differences and gaps in the evidence shareholders can use to assess how investment decisions affect markets.
View in Research hub → - Development banks revise how they measure mobilisation and private finance ↗
BII, through EDFI, and UK-backed multilateral banks are covered by a new joint methodology package. It updates mobilisation rules and adds a separate generation measure for institution-backed finance; work on catalysation continues. The guides require these different indicators to remain separate. No new UK financial commitment is announced.

Rob Moore and Ian Mitchell examine BII investment, UKEF support and UK guarantees through multilateral banks alongside aid spending. Their paper calls for stronger coordination and reporting. Its estimates and future scenarios depend on explicit assumptions and do not establish new capital payments.

New OECD research examines mandates, risk frameworks and staff incentives across development banks and DFIs, including BII and UK-backed multilaterals. It argues that mobilisation targets need to account for additionality and harder markets.
