AFII - Anthropocene Fixed Income Institute

AFII’s philosophy is that it's through the buy and sell decisions of bond portfolio managers and traders in the market that we can change the cost-of-capital in favour of a sustainable future. It’s grimy, technical and quantitative; it's an everyday struggle for alpha, but fixed income is extremely powerful when you direct it for a sustainable purpose.

The idea for AFII emerged from a series of lectures, “Fixed income in the Anthropocene”, conducted by founder Dr Ulf Erlandsson over the course of 2019. Ulf was a credit portfolio manager at the Fourth Swedish State Pension Fund (AP4) and a quant strategist at Barclays Capital. He was one of the pioneers in the green bond market as well as in high-frequency credit derivative trading. Following Ulf's return to investing in 2026, Justine Leigh-Bell, who had previously helped build the Climate Bonds Initiative as Deputy CEO, took the leadership position at AFII as CEO, after five years as both Executive Director and co-CEO working alongside Ulf.

AFII was propelled into existence by generous philanthropic organisations aligned with our goals. We have a global market focus with a growing team of experienced market practitioners producing innovative research, analysis and portfolio tools to support the fixed income community in delivering a sustainable transition.
