Global investors have backed Asian Infrastructure Investment Bank (AIIB) to raise $2.5bn (€2.23bn) via bonds for infrastructure investment.

The development bank said the debut global bond attracted orders from over 90 investors across the globe representing 27 countries.

The five-year bond was backed by central banks, fund manager, insurers and pension schemes, AIIB said.

AIIB said the amount raised will be used for sustainable infrastructure investing, developing cross-border connectivity, and promoting environmental, social and governance (ESG) investing in emerging Asia.

Thierry de Longuemar, AIIB’s CFO said: “This bond is reflective of investor demand globally for high-quality sustainable investments. AIIB’s outlook has always been global with founding members from Asia, Africa, South America and Europe.

“We were delighted to see demand from such a diversified group of investors in the book and look forward to showing our global investor base the positive contribution that this capital will have in Asia and beyond.�

AIIB president Jin Liqun said the growing institutional demand for fiscally sustainable, revenue-positive projects and support for AIIB’s unique operating model is evidenced by the almost $8bn of financings already approved by the bank.

“By participating in capital markets, we can harness further financial support from a global investor base, which will enable us to catalyze infrastructure investment and accelerate adoption of ESG investing principles in emerging Asia.�
