The loan has a maturity of 15 years, SBI said in a statement.
The process of fund raising was facilitated by SBI's subsidiary, SBI Capital Markets.
With a twin focus on agricultural and micro-enterprise loans, the facility is designed to further strengthen and extend SBI's priority sector lending activities.
The pact was signed by V G Kannan, Managing Director, SBI on behalf of the state-run lender, while KfW was represented by Roland Siller, Director General Europe and Asia and Nicolai Tust, Principal Country Manager.
Kannan said he expects the relationship to further grow in other strategic sectors like clean energy where SBI has already committed to support in line with Indian government's initiatives to reduce the carbon footprint.
