KfW was founded in 1948 in the post-war period, initiated by the Allies and the Federal Republic of Germany to specifically promote the reconstruction of the war-damaged economy and infrastructure, thus enabling an economic fresh start.

The primary goal was to provide long-term, low-interest loans for the reconstruction of industry, housing, infrastructure, and support for small and medium-sized enterprises.

In the 1950s and 1960s, KfW significantly contributed to expanding housing construction, supported SMEs, and increasingly engaged in social infrastructure such as health and education.

During this period, KfW began to consider environmental issues—for example, by supporting projects in renewable energy and environmental protection, which was a relatively new funding area at the time.

KfW expanded its international involvement, supporting development cooperation and the rebuilding of the new federal states after German reunification. It also intensified its promotion of innovation and technology.

Today, sustainability is a central part of KfW’s strategy. The bank actively supports projects related to energy efficiency, climate protection, and social development. This commitment underscores KfW’s role as a promotional institution for sustainable growth.

From providing purely reconstruction and financing assistance, KfW has developed into a broadly positioned promotional bank pursuing economic, social, and ecological goals. It operates nationally and internationally to promote sustainable development.

KfW is one of the world’s leading promotional banks. It supports the German SME sector, social infrastructure, environmental and climate protection projects, and is an important actor in international development financing.

In the 2020s, KfW has notably strengthened its role in managing the COVID-19 pandemic by providing extensive liquidity support to companies. Additionally, it focuses heavily on climate and environmental protection, supports the energy transition, and promotes innovation in digitalisation and sustainable technologies. KfW places increasing emphasis on ESG criteria and sustainable financing to actively shape the transition to a climate-neutral economy.
