AI’s biggest names are quickly becoming some of the largest and longest-dated issuers in investment grade credit. We believe this borrowing boom raises new risks for the passive portfolios that track bond indices, while creating opportunities for those with an active edge.

Why invest in the Rathbone Greenbank Global Sustainable Bond Fund
Flexible exposure to the entire fixed income market
The fund can invest across the fixed income universe including high yield and government bonds, with the majority of the portfolio within investment grade credit.
Specialist research and oversight
Our investment team is supported by the Responsible Investment Centre of Excellence, bringing together environmental, social, and governance (ESG) integration, stewardship, and ethical and sustainable research. The Centre screen every investment to ensure adherence to the fund sustainability criteria by a team independent of the investment team.
Tried and tested investment process
Our disciplined approach assesses every bond against our ‘Four Cs’ Plus framework (Character, Capacity, Collateral and Covenants).
Truly active
We believe active decision-making is essential in fixed income. Our approach combines credit research and sustainability analysis to determine the holdings that earn a place in the portfolio.
A robust sustainability framework
Combining ESG integration, negative screening, positive alignment and stewardship. This ensures every investment in the fund is aligned with one of our eight sustainable development themes.
While bonds can help reduce the overall risk of a portfolio, they are not risk free. Changes in interest rates, inflation and market conditions can affect the value of investments and the income they generate. Investors may get back less than they originally invested.
