MONGOLIA —The Asian Infrastructure Investment Bank (AIIB) has entered Mongolia’s commercial banking market through a five-year senior unsecured green loan to Khan Bank, establishing its first nonsovereign-backed financing in the country and its first investment in a Mongolian financial institution. AIIB is providing USD 80 million as lead arranger, while Korea Development Bank (KDB) contributes USD 20 million as a parallel lender. A further USD 30 million comes from Asian B-loan participants, bringing the total financing package to USD 130 million.
The transaction is structured to enable disbursements in either US dollars or Mongolian tugrik, offering flexibility for financing eligible investments in a market where currency exposure can influence project costs and repayment risks. The additional USD 50 million from KDB and B-loan participants also broadens the pool of capital available beyond AIIB’s direct contribution.
Khan Bank will channel the proceeds into qualifying green investments across renewable energy, energy efficiency, environmentally sustainable buildings, pollution control, water management and treatment, and clean transport. By using an established domestic bank as the lending intermediary, the facility can reach businesses and projects beyond the limited number of large borrowers typically served by direct international development financing. The ultimate allocation will depend on project eligibility and the bank’s implementation of the green lending framework.
The financing is relevant to Mongolia’s climate agenda, as the country faces significant exposure to climate-related risks and has committed to reducing greenhouse gas emissions by 30.3% by 2035. Additional financing for cleaner energy, efficient buildings and water infrastructure could help businesses manage resource costs while supporting national environmental objectives. For local companies, access to longer-term green credit may improve the feasibility of investments that require substantial upfront capital.
The deal also creates a channel for international development lenders to support Mongolia’s private sector without relying exclusively on sovereign borrowing. Its unsecured structure places the financing at the level of the banking institution rather than tying it to a government-backed loan, while the dual-currency option may help accommodate borrowers with different revenue and funding profiles. However, the announcement does not specify individual projects, lending rates, allocation targets or expected emissions reductions.
AIIB is a multilateral development bank that finances sustainable infrastructure and other development priorities across Asia and beyond. Khan Bank is Mongolia’s largest commercial bank, with a nationwide network serving households and businesses. Korea Development Bank is a South Korean policy bank supporting industrial development and corporate financing. Their participation combines multilateral funding, domestic lending capacity and additional institutional capital to expand Mongolia’s green finance market, with results dependent on project selection, loan deployment and repayment performance.
